Description


BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention


[0003] The present invention relates generally to reverse-turn mimetic structures and to a chemical library relating thereto. The invention also relates to applications in the treatment of medical conditions, e.g., cancer diseases, and pharmaceutical compositions comprising the mimetics.


[0004] 2. Description of the Related Art


[0005] Random screening of molecules for possible activity as therapeutic agents has occurred for many years and resulted in a number of important drug discoveries. While advances in molecular biology and computational chemistry have led to increased interest in what has been termed “rational drug design”, such techniques have not proven as fast or reliable as initially predicted. Thus, in recent years there has been a renewed interest and return to random drug screening. To this end, particular strides having been made in new technologies based on the development of combinatorial chemistry libraries, and the screening of such libraries in search for biologically active members.


[0006] In general, combinatorial chemistry libraries are simply a collection of molecules. Such libraries vary by the chemical species within the library, as well as the methods employed to both generate the library members and identify which members interact with biological targets of interest. While this field is still young, methods for generating and screening libraries have already become quite diverse and sophisticated. For example, a recent review of various combinatorial chemical libraries has identified a number of such techniques (Dolle, J. Com. Chem., 2(3): 383-433, 2000), including the use of both tagged and untagged library members (Janda, Proc. Natl. Acad. Sci. USA 91:10779-10785, 1994).


[0007] Initially, combinatorial chemistry libraries were generally limited to members of peptide or nucleotide origin. To this end, the techniques of Houghten et al. illustrate an example of what is termed a “dual-defined iterative” method to assemble soluble combinatorial peptide libraries via split synthesis techniques (Nature (London) 354:84-86, 1991; Biotechniques 13:412-421, 1992; Bioorg. Med. Chem. Lett. 3:405-412, 1993). By this technique, soluble peptide libraries containing tens of millions of members have been obtained. Such libraries have been shown to be effective in the identification of opioid peptides, such as methionine- and leucine-enkephalin (Dooley and Houghten, Life Sci. 52, 1509-1517, 1993), and a N-acylated peptide library has been used to identify acetalins, which are potent opioid antagonists (Dooley et al., Proc. Natl. Acad. Sci. USA 90:10811-10815, 1993. More recently, an all D-amino acid opioid peptide library has been constructed and screened for analgesic activity against the mu (“m”) opioid receptor (Dooley et al, Science 266:2019-2022, 1994).


[0008] While combinatorial libraries containing members of peptide and nucleotide origin are of significant value, there is still a need in the art for libraries containing members of different origin. For example, traditional peptide libraries to a large extent merely vary the amino acid sequence to generate library members. While it is well recognized that the secondary structures of peptides are important to biological activity, such peptide libraries do not impart a constrained secondary structure to its library members.


[0009] To this end, some researchers have cyclized peptides with disulfide bridges in an attempt to provide a more constrained secondary structure (Tumelty et al., J. Chem. Soc. 1067-68, 1994; Eichler et al., Peptide Res. 7:300-306, 1994). However, such cyclized peptides are generally still quite flexible and are poorly bioavailable, and thus have met with only limited success.


[0010] More recently, non-peptide compounds have been developed which more closely mimic the secondary structure of reverse-turns found in biologically active proteins or peptides. For example, U.S. Pat. No. 5,440,013 to Kahn and published PCT applications nos. WO94/03494, WO01/00210A1, and WO01/16135A2 to Kahn each disclose conformationally constrained, non-peptidic compounds, which mimic the three-dimensional structure of reverse-turns. In addition, U.S. Pat. No. 5,929,237 and its continuation-in-part U.S. Pat. No. 6,013,458, both to Kahn, disclose conformationally constrained compounds which mimic the secondary structure of reverse-turn regions of biologically active peptides and proteins. The synthesis and identification of conformationally constrained, reverse-turn mimetics and their application to diseases were well reviewed by Obrecht (Advances in Med. Chem., 4, 1-68, 1999).


[0011] While significant advances have been made in the synthesis and identification of conformationally constrained, reverse-turn mimetics, there remains a need in the art for small molecules which mimic the secondary structure of peptides. There is also a need in the art for libraries containing such members, as well as techniques for synthesizing and screening the library members against targets of interest, particularly biological targets, to identify bioactive library members.


[0012] The present invention also fulfills these needs, and provides further related advantages by providing confomationally constrained compounds which mimic the secondary structure of reverse-turn regions of biologically active peptides and proteins.


[0013] Wnt signaling pathway regulates a variety of processes including cell growth, oncogenesis, and development (Moon et al., 1997, Trends Genet. 13, 157-162: Miller et al., 1999, Oncogene 18, 7860-7872: Nusse and Varmus, 1992, Cell 69, 1073-1087: Cadigan and Nusse, 1997, Genes Dev. 11, 3286-3305: Peifer and Polakis, 2000 Science 287, 1606-1609: Polakis 2000, Genes Dev. 14, 1837-1851). Wnt signaling pathway has been intensely studied in a variety of organisms. The activation of TCF4/β-catenin mediated transcription by Wnt signal transduction has been found to play a key role in its biological functions (Molenaar et al., 1996, Cell 86:391-399; Gat et al., 1998 Cell 95:605-614; Orford et al., 1999 J. Cell. Biol. 146:855-868; Bienz and Clevers, 2000, Cell 103:311-20).


[0014] In the absence of Wnt signals, tumor suppressor gene adenomatous polyposis coli (APC) simultaneously interacts with the serine kinase glycogen synthase kinase (GSK)-3β and β-catenin (Su et al., 1993, Science 262, 1734-1737: Yost et al., 1996 Genes Dev. 10, 1443-1454: Hayashi et al., 1997, Proc. Natl. Acad. Sci. USA, 94, 242-247: Sakanaka et al., 1998, Proc. Natl. Acad. Sci. USA, 95, 3020-3023: Sakanaka and William, 1999, J. Biol. Chem 274, 14090-14093). Phosphorylation of APC by GSK-3β regulates the interaction of APC with β-catenin, which in turn may regulate the signaling function of β-catenin (B. Rubinfeld et al., Science 272, 1023, 1996). Wnt signaling stabilizes β-catenin allowing its translocation to the nucleus where it interacts with members of the lymphoid enhancer factor (LEF1)/T-cell factor (TCF4) family of transcription factors (Behrens et al., 1996 Nature 382, 638-642: Hsu et al., 1998, Mol. Cell. Biol. 18, 4807-4818: Roose et all., 1999 Science 285, 1923-1926).


[0015] Recently c-myc, a known oncogene, was shown to be a target gene for β-catenin/TCF4-mediated transcription (He et al., 1998 Science 281 1509-1512: Kolligs et al., 1999 Mol. Cell. Biol. 19, 5696-5706). Many other important genes, including cyclin D1, and metalloproteinase, which are also involved in oncogenesis, have been identified to be regulated by TCF4/bata-catenin transcriptional pathway (Crawford et al., 1999, Oncogene 18, 2883-2891: Shtutman et al., 1999, Proc. Natl. Acad. Sci. USA., 11, 5522-5527: Tetsu and McCormick, 1999 Nature, 398, 422-426).


[0016] Moreover, overexpression of several downstream mediators of Wnt signaling has been found to regulate apoptosis (Moris et al., 1996, Proc. Natl. Acad. Sci. USA, 93, 7950-7954: He et al., 1999, Cell 99, 335-345: Orford et al, 1999 J. Cell. Biol., 146, 855-868: Strovel and Sussman, 1999, Exp. Cell. Res., 253, 637-648). Overexpression of APC in human colorectal cancer cells induced apoptosis (Moris et al., 1996, Proc. Natl. Acad. Sci. USA., 93, 7950-7954), ectopic expression of β-catenin inhibited apoptosis associated with loss of attachment to extracellular matrix (Orford et al, 1999, J. Cell Biol. 146, 855-868). Inhibition of TCF4/β-catenin transcription by expression of dominant-negative mutant of TCF4 blocked Wnt-1-mediated cell survival and rendered cells sensitive to apoptotic stimuli such as anti-cancer agent (Shaoqiong Chen et al., 2001, J. Cell. Biol., 152, 1, 87-96) and APC mutation inhibits apoptosis by allowing constitutive survivin expression, a well-known anti-apoptotic protein (Tao Zhang et al., 2001, Cancer Research, 62, 8664-8667).


[0017] Although mutations in the Wnt gene have not been found in human cancer, a mutation in APC or β-catenin, as is the case in the majority of colorectal tumors, results in inappropriate activation of TCF4, overexpression of c-myc and production of neoplastic growth (Bubinfeld et al, 1997, Science, 275, 1790-1792: Morin et al, 1997, Science, 275, 1787-1790: Casa et al, 1999, Cell. Growth. Differ. 10, 369-376). The tumor suppressor gene (APC) is lost or inactivated in 85% of colorectal cancers and in a variety of other cancers as well (Kinzler and Vogelstein, 1996, Cell 87, 159-170). APC's principal role is that of a negative regulator of the Wnt signal transduction cascade. A center feature of this pathway involves the modulation of the stability and localization of a cytosolic pool of β-catenin by interaction with a large Axin-based complex that includes APC. This interaction results in phosphorylation of β-catenin thereby targeting it for degradation.


[0018] CREB binding proteins (CBP)/p300 were identified initially in protein interaction assays, first through its association with the transcription factor CREB (Chrivia et al, 1993, Nature, 365, 855-859) and later through its interaction with the adenoviral-transforming protein ElA (Stein et al., 1990, J. Viol., 64, 4421-4427: Eckner et al., 1994, Genes. Dev., 8, 869-884). CBP had a potential to participate in variety of cellular functions including transcriptional coactivator function (Shikama et al., 1997, Trends. Cell. Biol., 7, 230-236: Janknecht and Hunter, 1996, Nature, 383, 22-23). CBP/p300 potentiates β-catenin-mediated activation of the siamois promoter, a known Wnt target (Hecht et al, 2000, EMBO J. 19, 8, 1839-1850). β-catenin interacts directly with the CREB-binding domain of CBP and β-catenin synergizes with CBP to stimulate the transcriptional activation of TCF4/β-catenin (Ken-Ichi Takemaru and Randall T. Moon, 2000 J. Cell. Biol., 149, 2, 249-254).



BRIEF SUMMARY OF THE INVENTION

[0019] From this background, it is seen that TCF4/β-catenin and CBP complex of Wnt pathway can be taken as target molecules for the regulation of cell growth, oncogenesis and apoptosis of cells, etc. Accordingly, the present invention addresses a need for compounds that block TCF4/β-catenin transcriptional pathway by inhibiting CBP, and therefore can be used for treatment of cancer, especially colorectal cancer.

[0044] In addition to naturally occurring amino acid side chain moieties, the amino acid side chain moieties of the present invention also include various derivatives thereof. As used herein, a “derivative” of an amino acid side chain moiety includes modifications and/or variations to naturally occurring amino acid side chain moieties.

For example, the compounds of this invention may be linked to one or more known compounds, such as biotin, for use in diagnostic or screening assay. Furthermore, R1, R2, R3, R4, R5, R6, R7, R8 or R9 may be a linker joining the compound to a solid support (such as a support used in solid phase peptide synthesis) or alternatively, may be the support itself. In this embodiment, linkage to another moiety or compound, or to a solid support, is preferable at the R1, R2, R7 or R9, or R9 position, and more preferably at the R1 or R2 position.


[0049] In the embodiment wherein A is —(CHR3)—, B is —(C═O)—, D is —(CHR5)—, E is —(C═O)—, and G is —(XR7)n—, the reverse turn mimetic compound of this invention has the following formula (II):

[0053] In a more specific embodiment wherein A is —(C═O)—, B is —(CHR4)—, D is —(C═O)—, E is -(ZR6)—, and G is (XR7)n—, the reverse turn mimetic compound of this invention has the following formula (IV):

[0054] wherein R1, R2, R4, R6, R7, W, X and n are as defined above, and Z is nitrogen or CH (when Z is nitrogen, then n is zero, and when Z is CH, then X is nitrogen and n is not zero). In a preferred embodiment, R1, R2, R6 and R7 represent the remainder of the compound, and R4 is selected from an amino acid side chain moiety. In one aspect, R6 or R7 is selected from an amino acid side chain moiety when Z and X are both CH.


[0055] These compounds may be prepared by utilizing appropriate starting component molecules (hereinafter referred to as “component pieces”). Briefly, in the synthesis of reverse-turn mimetic structures having formula (I), first and second component pieces are coupled to form a combined first-second intermediate, if necessary, third and/or fourth component pieces are coupled to form a combined third-fourth intermediate (or, if commercially available, a single third intermediate may be used), the combined first-second intermediate and third-fourth intermediate (or third intermediate) are then coupled to provide a first-second-third-fourth intermediate (or first-second-third intermediate) which is cyclized to yield the reverse-turn mimetic structures of this invention. Alternatively, the reverse-turn mimetic structures of formula (I) may be prepared by sequential coupling of the individual component pieces either stepwise in solution or by solid phase synthesis as commonly practiced in solid phase peptide synthesis.


[0056] Specific component pieces and the assembly thereof to prepare compounds of the present invention are illustrated in FIG. 1. For example, a “first component piece” may have the following formula S1:
15


[0057] wherein R2 is as defined above, and R is a protective group suitable for use in peptide synthesis, where this protection group may be joined to a polymeric support to enable solid-phase synthesis. Suitable R groups include alkyl groups and, in a preferred embodiment, R is a methyl group. In FIG. 1, one of the R groups is a polymeric (solid) support, indicated by “Pol” in the Figure. Such first component pieces may be readily synthesized by reductive amination of H2N—R2 with CH(OR)2—CHO, or by a displacement reaction between H2N—R2 and CH(OR)2—CH2-LG (wherein LG refers to a leaving group, e.g., a halogen (Hal) group).


[0058] A “second component piece” may have the following formula S2:
16


[0059] where P is an amino protection group suitable for use in peptide synthesis, L1 is hydroxyl or a carboxyl-activation group, and R4 is as defined above. Preferred protection groups include t-butyl dimethylsilyl (TBDMS), t-butyloxycarbonyl (BOC), methyloxycarbonyl (MOC), 9H-fluorenylmethyloxycarbonyl (FMOC), and allyloxycarbonyl (Alloc). N-Protected amino acids are commercially available; for example, FMOC amino acids are available from a variety of sources. In order for the second component piece to be reactive with the first component piece, L1 is a carboxyl-activation group, and the conversion of carboxyl groups to activated carboxyl groups may be readily achieved by methods known in the art for the activation of carboxyl groups. Suitable activated carboxylic acid groups include acid halides where L, is a halide such as chloride or bromide, acid anhydrides where L1 is an acyl group such as acetyl, reactive esters such as an N-hydroxysuccinimide esters and pentafluorophenyl esters, and other activated intermediates such as the active intermediate formed in a coupling reaction using a carbodiimide such as dicyclohexylcarbodiimide (DCC). Accordingly, commercially available N-protected amino acids may be converted to carboxylic activated forms by means known to one of skill in the art.


[0060] In the case of the azido derivative of an amino acid serving as the second component piece, such compounds may be prepared from the corresponding amino acid by the reaction disclosed by Zaloom et al. (J. Org. Chem. 46:5173-76, 1981).


[0061] Alternatively, the first component piece of the invention may have the following formula S1′:
17


[0062] wherein R is as defined above and L2 is a leaving group such as halogen atom or tosyl group, and the second component piece of the invention may have the following formula S2′:
18


[0063] wherein R2, R4 and P are as defined above,


[0064] A “third component piece” of this invention may have the following formula S3:
19


[0065] where G, E, L1 and L2 are as defined above. Suitable third component pieces are commercially available from a variety of sources or can be prepared by methods well known in organic chemistry.


[0066] In FIG. 1, the compound of formula (1) has —(C═O)— for A, —(CHR4)— for B, —(C═O)— for D, and —(CR6)— for E. Compounds of formula (1) wherein a carbonyl group is at position B and an R group is at position B, i.e., compounds wherein A is —(CHR3)— and B is —(C═O)—, may be prepared in a manner analogous to that shown in FIG. 1, as illustrated in FIG. 2. FIG. 2 also illustrates adding a fourth component piece to the first-second-third component intermediate, rather than attaching the fourth component piece to the third component piece prior to reaction with the first-second intermediate piece. In addition, FIG. 2 illustrates the prepartion of compounds of the present invention wherein D is —(CHR5)— (rather than —(C═O)— as in FIG. 1), and E is —(C═O)— (rather than —(CHR6)— as in FIG. 1). Finally, FIG. 2 illustrates the preparation of compounds wherein G is NR7.


[0067] Thus, as illustrated above, the reverse-turn mimetic compounds of formula (I) may be synthesized by reacting a first component piece with a second component piece to yield a combined first-second intermediate, followed by reacting the combined first-second intermediate with third component pieces sequentially to provide a combined first-second-third-fourth intermediate, and then cyclizing this intermediate to yield the reverse-turn mimetic structure.


[0068] The syntheses of representative component pieces of this invention are described in Preparation Examples and working Examples.


[0069] The reverse-turn mimetic structures of formula (III) and (IV) may be made by techniques analogous to the modular component synthesis disclosed above, but with appropriate modifications to the component pieces.


[0070] The reverse-turn mimetic structures of the present invention are useful as bioactive agents, such as diagnostic, prophylactic, and therapeutic agents. For example, the reverse-turn mimetic structures of the present invention may be used for modulating a cell signaling transcription factor related peptides in a warm-blooded animal, by a method comprising administering to the animal an effective amount of the compound of formula (I).


[0071] Further, the reverse-turn mimetic structures of the present invention may also be effective for inhibiting peptide binding to PTB domains in a warm-blooded animal; for modulating G protein coupled receptor (GPCR) and ion channel in a warm-blooded animal; for modulating cytokines in a warm-blooded animal.


[0072] Meanwhile, it has been found that the compounds of the formula (I), especially compounds of formula (VI) are effective for inhibiting or treating disorders modulated by Wnt-signaling pathway, such as cancer, especially colorectal cancer.
20


[0073] wherein, Ra is a bicyclic aryl group having 8 to 11 ring members, which may have 1 to 3 heteroatoms selected from nitrogen, oxygen or sulfur, and Rb is a monocyclic aryl group having 5 to 7 ring members, which may have 1 to 2 heteroatoms selected from nitrogen, oxygen or sulfur, and an aryl group in the compound may have one or more substituents selected from a group consisting of halide, hydroxy, cyano, lower alkyl, and lower alkoxy group.


[0074] In another aspect, it is an object of the present invention to provide a pharmaceutical composition comprising a safe and effective amount of the compound having general formula (VI) and pharmaceutically acceptable carrier, which can be used for treatment of disorders modulated by Wnt signaling pathway, especially by TCF4-β-catenin-CBP complex.


[0075] Further, the present invention is to provide a method for inhibiting the growth of tumor cells by using the above-described composition of the present invention; a method for inducing apoptosis of tumor cells by using the above-described composition of the present invention; a method for treating a disorder modulated by TCF4-β catenin-CBP complex by using the above-described composition of the present invention; and a method of treating cancer such as colorectal cancer by administering the composition of the present invention together with other anti-cancer agent such as 5-fluorouracil (5-FU), taxol, cisplatin, mitomycin C, tegafur, raltitrexed, capecitabine, and irinotecan, etc.


[0076] In a preferred embodiment of the present invention, the compound of the present invention has a (6S,10R)-configuration as follows:
21


[0077] wherein Ra and Rb have the same meanings as defined above.


[0078] In another aspect of this invention, libraries containing reverse-turn mimetic structures of the present invention are disclosed. Once assembled, the libraries of the present invention may be screened to identify individual members having bioactivity. Such screening of the libraries for bioactive members may involve; for example, evaluating the binding activity of the members of the library or evaluating the effect the library members have on a functional assay. Screening is normally accomplished by contacting the library members (or a subset of library members) with a target of interest, such as, for example, an antibody, enzyme, receptor or cell line. Library members which are capable of interacting with the target of interest, are referred to herein as “bioactive library members” or “bioactive mimetics”. For example, a bioactive mimetic may be a library member which is capable of binding to an antibody or receptor, or which is capable of inhibiting an enzyme, or which is capable of eliciting or antagonizing a functional response associated, for example, with a cell line. In other words, the screening of the libraries of the present invention determines which library members are capable of interacting with one or more biological targets of interest. Furthermore, when interaction does occur, the bioactive mimetic (or mimetics) may then be identified from the library members. The identification of a single (or limited number) of bioactive mimetic(s) from the library yields reverse-turn mimetic structures which are themselves biologically active, and thus are useful as diagnostic, prophylactic or therapeutic agents, and may further be used to significantly advance identification of lead compounds in these fields.


[0079] Synthesis of the peptide mimetics of the library of the present invention may be accomplished using known peptide synthesis techniques, in combination with the first, second and third component pieces of this invention. More specifically, any amino acid sequence may be added to the N-terminal and/or C-terminal of the conformationally constrained reverse-turn mimetic. To this end, the mimetics may be synthesized on a solid support (such as PAM resin) by known techniques (see, e.g., John M. Stewart and Janis D. Young, Solid Phase Peptide Synthesis, 1984, Pierce Chemical Comp., Rockford, Ill.) or on a silyl-linked resin by alcohol attachment (see Randolph et al., J. Am Chem. Soc. 117:5712-14, 1995).


[0080] In addition, a combination of both solution and solid phase synthesis techniques may be utilized to synthesize the peptide mimetics of this invention. For example, a solid support may be utilized to synthesize the linear peptide sequence up to the point that the conformationally constrained reverse-turn is added to the sequence. A suitable conformationally constrained reverse-turn mimetic structure which has been previously synthesized by solution synthesis techniques may then be added as the next “amino acid” to the solid phase synthesis (i.e., the conformationally constrained reverse-turn mimetic, which has both an N-terminus and a C-terminus, may be utilized as the next amino acid to be added to the linear peptide). Upon incorporation of the conformationally constrained reverse-turn mimetic structures into the sequence, additional amino acids may then be added to complete the peptide bound to the solid support. Alternatively, the linear N-terminus and C-terminus protected peptide sequences may be synthesized on a solid support, removed from the support, and then coupled to the conformationally constrained reverse-turn mimetic structures in solution using known solution coupling techniques.


[0081] In another aspect of this invention, methods for constructing the libraries are disclosed. Traditional combinatorial chemistry techniques (see, e.g., Gallop et al., J. Med. Chem. 37:1233-1251, 1994) permit a vast number of compounds to be rapidly prepared by the sequential combination of reagents to a basic molecular scaffold. Combinatorial techniques have been used to construct peptide libraries derived from the naturally occurring amino acids. For example, by taking 20 mixtures of 20 suitably protected and different amino acids and coupling each with one of the 20 amino acids, a library of 400 (i.e., 202) dipeptides is created. Repeating the procedure seven times results in the preparation of a peptide library comprised of about 26 billion (i.e., 208) octapeptides.


[0082] Specifically, synthesis of the peptide mimetics of the library of the present invention may be accomplished using known peptide synthesis techniques, for example, the General Scheme of [4,4,0] Reverse-Turn Mimetic Library as follows:
22


[0083] Synthesis of the peptide mimetics of the libraries of the present invention was accomplished using a FlexChem Reactor Block which has 96 well plates by known techniques. In the above scheme ‘Pol’ represents a bromoacetal resin (Advanced ChemTech) and detailed procedure is illustrated below.


[0084] Step 1


[0085] A bromoacetal resin (37 mg, 0.98 mmol/g) and a solution of R2-amine in DMSO (1.4 mL) were placed in a Robbins block (FlexChem) having 96 well plates. The reaction mixture was shaken at 60° C. using a rotating oven [Robbins Scientific] for 12 hours. The resin was washed with DMF, MeOH, and then DCM


[0086] Step 2


[0087] A solution of commercial available FmocAmino Acids (4 equiv.), PyBob (4 equiv.), HOAt (4 equiv.), and DIEA (12 equiv.) in DMF was added to the resin. After the reaction mixture was shaken for 12 hours at room temperature, the resin was washed with DMF, MeOH, and then DCM.


[0088] Step 3


[0089] To the resin swollen by DMF before reaction was added 25% piperidine in DMF and the reaction mixture was shaken for 30 min at room temperature. This deprotection step was repeated again and the resin was washed with DMF, Methanol, and then DCM. A solution of hydrazine acid (4 equiv.), HOBt (4 equiv.), and DIC (4 equiv.) in DMF was added to the resin and the reaction mixture was shaken for 12 hours at room temperature. The resin was washed with DMF, MeOH, and then DCM.


[0090] Step 4a (Where Hydrazine Acid is MOC Carbamate)


[0091] The resin obtained in Step 3 was treated with formic acid (1.2 mL each well) for 18 hours at room temperature. After the resin was removed by filtration, the filtrate was condensed under a reduced pressure using SpeedVac [SAVANT] to give the product as oil. The product was diluted with 50% water/acetonitrile and then lyophilized after freezing.


[0092] Step 4b (Where Fmoc Hydrazine Acid is Used to Make Urea Through Isocynate)


[0093] To the resin swollen by DMF before reaction was added 25% piperidine in DMF and the reaction mixture was shaken for 30 min at room temperature. This deprotection step was repeated again and the resin was washed with DMF, Methanol, then DCM. To the resin swollen by DCM before reaction was added isocynate (5 equiv.) in DCM. After the reaction mixture was shaken for 12 hours at room temperature the resin was washed with DMF, MeOH, then DCM. The resin was treated with formic acid (1.2 mL each well) for 18 hours at room temperature. After the resin was removed by filtration, the filtrate was condensed under a reduced pressure using SpeedVac [SAVANT] to give the product as oil. The product was diluted with 50% water/acetonitrile and then lyophilized after freezing.


[0094] Step 4c (Where Fmoc-hydrazine Acid is Used to Make Urea Through Active Carbamate)


[0095] To the resin swollen by DMF before reaction was added 25% piperidine in DMF and the reaction mixture was shaken for 30 min at room temperature. This deprotection step was repeated again and the resin was washed with DMF, MeOH, and then DCM. To the resin swollen by DCM before reaction was added p-nitrophenyl chloroformate (5 equiv.) and diisopropyl ethylamine (5 equiv.) in DCM. After the reaction mixture was shaken for 12 hours at room temperature, the resin was washed with DMF, MeOH, and then DCM. To the resin was added primary amines in DCM for 12 hours at room temperature and the resin was washed with DMF, MeOH, and then DCM. After reaction the resin was treated with formic acid (1.2 mL each well) for 18 hours at room temperature. After the resin was removed by filtration, the filtrate was condensed under a reduced pressure using SpeedVac [SAVANT] to give the product as oil. The product was diluted with 50% water/acetonitrile and then lyophilized after freezing.


[0096] To generate these block libraries the key intermediate hydrazine acids were synthesized according to the procedure illustrated in Preparation Examples.

[0099] Synthesis of the peptide mimetics of the bicyclic template libraries of the present invention was accomplished using FlexChem Reactor Block which has 96 well plate by known techniques. In the above scheme ‘Pol’ represents Bromoacetal resin (Advanced ChemTech) and detailed procedure is illustrated below.


[0100] Step 1


[0101] The bromoacetal resin (1.6 mmol/g) and a solution of R1 amine in DMSO (2M solution) were placed in 96 well Robbins block (FlexChem). The reaction mixture was shaken at 60° C. using rotating oven [Robbins Scientific] for 12 hours. The resin was washed with DMF, MeOH, and then DCM


[0102] Step 2


[0103] A solution of commercial available Fmoc-Amino Acids (4 equiv.), PyBob (4 equiv.), HOAt (4 equiv.), and DIEA (12 equiv.) in DMF was added to the resin. After the reaction mixture was shaken for 12 hours at room temperature, the resin was washed with DMF, MeOH, and then DCM.


[0104] Step 3


[0105] To the resin swollen by DMF before reaction was added 25% piperidine in DMF. After the reaction mixture was shaken for 30 min at room temperature. This deprotection step was repeated again and then washed with DMF, Methanol, then DCM. A solution of hydrazine carbamoyl chloride (4 equiv.), HOBt (4 equiv.), and DIC (4 equiv.) in DMF was added to the resin. After the reaction mixture was shaken for 12 hours at room temperature, the resin was washed with DMF, MeOH, and then DCM.


[0106] Step 4


[0107] To the resin swollen by DMF before reaction was added 25% piperidine in DMF. After the reaction mixture was shaken for 30 min at room temperature. This deprotection step was repeated again and then washed with DMF, Methanol, then DCM. To the resin swollen by DCM before reaction was added R1-isocynate (5 equiv.) in DCM. After the reaction mixture was shaken for 12 hours at room temperature the resin was washed with DMF, MeOH, then DCM.


[0108] Step 5


[0109] The resin was treated with formic acid (1.2 mL each well) for 18 hours at room temperature. After the resin was removed by filtration, the filtrate was condensed under reduced pressure using SpeedVac [SAVANT] to give the product as oil. These products were diluted with 50% water/acetonitrile and then lyophilized after freezing.

[0111] In a further aspect of this invention, the present invention provides methods for screening the libraries for bioactivity and isolating bioactive library members.


[0112] In yet another aspect, the present invention provides a method for carrying out a binding assay. The method includes providing a composition that includes a first co-activator, an interacting protein, and a test compound. The amino acid structure of the first co-activator includes a binding motif of LXXLL, LXXLI or FxxFF wherein X is any amino acid. The method further includes detecting an alteration in binding between the first co-activator and the interacting protein due to the presence of the compound, and then characterizing the test compound in terms of its effect on the binding.


[0113] The assay may be carried out by any means that can measure the effect of a test compound on the binding between two proteins. Many such assays are known in the art and can be utilized in the method of the present invention, including the so-called Two-Hybrid and Split-Hybrid systems.


[0114] The Two-Hybrid system, and various means to carry out an assay using this system, are described in, e.g., U.S. Pat. No. 6,410,245. The Split-Hybrid system has been described by, e.g., Hsiu-Ming Shiu et al. Proc. Natl. Acad. Sci. USA, 93:13896-13901, November 1996; and John D. Crispino, et al. Molecular Cell, 3:1-20, February 1999. In the Split-Hybrid system, a fusion protein is utilized where protein X is fused to the lexA DNA binding domains (pLexA) and protein Y is fused to the transcription activator VP16 (pSHM.1-LacZ). Interaction between lexA-X and VP16-Y leads to the expression of the Tetracycline repressor protein (TetR). TetR prevents transcription of the HIS3 reporter gene, making the cells unable to grow on media lacking histidine. Disruption of protein-protein interaction will restore the ability of the cells to grow on such media by shutting down expression of the tetracycline repressor. Accordingly, compounds of the present invention may be added to the growing cells, and if the addition of the compound restores the ability of the cells to grow on the media, the compound may be seen as an effective disruptor of the protein-protein interaction.


[0115] The yeast strains required to make the Split-Hybrid system work can be employed with two hybrid LexANP16 constructs such as those described by Stanley M. Hollenberg, et al. Molecular and Cellular Biology 15(7):3813-3822, July 1995. A useful modification of the Split-Hybrid system was utilized by Takemaru, K. I. and Moon, R. T. J. of Cell Biol. 149:249-254, 2000.


[0116] Other assay formats are also suitable. For example, reporter gene assays for AP-1, ELISA, for example, blocking the production of IL-2 by a T-cell line after stimulation with CD3 and CD28 to look for inhibitors of IL-2 transcription. Direct binding assays (between coactivators and their partners) can be performed by surface plasmon resonance spectroscopy (Biacore, Sweden, manufactures suitable instruments) or ELISA.


[0117] Exemplary transcriptional regulators include, without limitation, VP16, VP64, p300, CBP, PCAF, SRC1 PvALF, AtHD2A and ERF-2. See, for example, Robyr et al. (2000) Mol.

[0118] In a preferred embodiment, the transcriptional coactivator is a human transcriptional coactivator. In another preferred embodiment, the transcriptional coactivator is a member of the p300/CBP family of co-activators which have histone acetyltransferase activity. p300 is described for example by Eckner et al, 1994 and CBP by Bannister and Kouzarides, 1996. For the purposes of the present invention, reference to p300/CBP refers to human allelic and synthetic variants of p300, and to other mammalian variants and allelic and synthetic variants thereof, as well as fragments of said human and mammalian forms of p300. In one aspect of the assay, the interacting protein is a transcription factor or a second co-activator.

In another aspect of the assay, the interacting protein is any one of ERAP140; RIP140; RIP160; Trip1; SWI1 (SNF); ARA70; RAP46; TIF1; TIF2; GRIP1; and TRAP. In another aspect of the invention, the interacting protein is any one of VP16; VP64; p300; CBP; PCAF; SRC1 PvALF; AtHD2A; ERF-2; OsGAI; HALF-1; C1; AP-1; ARF-5; ARF-6; ARF-7; ARF-8; CPRF1; CPRF4; MYC-RP/GP; and TRAB1. In another aspect of the invention, the first co-activator is CBP or p300.


[0120] The test compound is selected from compounds as described herein. For example, compounds having the formula (I), (II), (III), (IV), (VI) and (VIa). Typically, a test compound will be evaluated at several different concentrations, where these concentrations will be selected, in part, based on the conditions of the assay, e.g., the concentrations of the first co-activator and the interacting protein. Concentrations in the range of about 0.1 to 10 μM are typical. In one aspect, the assay evaluates the relative efficacy of two compounds to affect the binding interaction between two proteins, where at least one of those two compounds is a compound of the present invention. The more effective compound can than serve as a reference compound in a study of the relationship between compound structure and compound activity.


[0121] The libraries of the present invention were screened for bioactivity by various techniques and methods. In general, the screening assay may be performed by (1) contacting the mimetics of a library with a biological target of interest, such as a receptor, to allow binding between the mimetics of the library and the target to occur, and (2) detecting the binding event by an appropriate assay, such as the calorimetric assay disclosed by Lam et al. (Nature 354:82-84, 1991) or Griminski et al. (Biotechnology 12:1008-1011, 1994) (both of which are incorporated herein by reference). In a preferred embodiment, the library members are in solution and the target is immobilized on a solid phase. Alternatively, the library may be immobilized on a solid phase and may be probed by contacting it with the target in solution.

[0123] It has been found according to the present invention that compounds of general formula (I), and especially the compounds of general formula (VI), can inhibit CBP-mediated transcriptional activation in cancer cells due to their specific binding to CBP. This conclusion is supported by immunoprecipitation of CBP of SW480 cells with compounds of the present invention.


[0124] The compounds of the present invention can also inhibit the survivin expression in SW480 cells, and therefore, inhibit the oncogenic activity in cancer cells. The compounds of the present invention can be used for inhibiting cancer cells, and thus, would be useful for the regulation of cell growth. Supporting such results, the compounds of the present invention further shows that it can induce the caspase-3 activation in SW480 cells, and therefore, induce the apoptotic activity in cells. The compounds of the present invention can be also advantageously used for inducing apoptosis in cells.


[0125] To confirm the oncogenic activity in cancer cell in in vitro MTS cytotoxicity assay was tested by following method.


[0126] (1) Cytotoxicity Test


[0127] SW480 or HCT116 cells were placed into 96 well microplate (104cells/well) and incubated for 24 hours at 37° C. The cells were treated with TCF4 compound at various concentrations for 24 hours. 20 μl of MTS solution (Promega) was added into each well and incubated for 2 hours at 37° C.

[0142] In another aspect of the present invention, a method for treating a disorder modulated by Wnt signaling pathway in which the method comprises administering to a patient a safe and effective amount of the compounds having general formula (I), especially the compound of general formula (VI) is disclosed.

Thus, it is another aspect of the present invention to provide a method for the treatment of disorder modulated by TCF4-βcatenin-CBP complex, using the compounds having the general formula (I), especially the compound of general formula (VI).


[0143] Further, because the treatment of cancer is also closely related to inducing apoptosis in cancer cells in a subject, the present invention is also directed to a method of inducing apoptosis in cancer cells using the compounds of general formula (I), especially the compound of general formula (VI).


[0144] It has been known from previous art that 5-FU [Fluorouracil; 5-fluoro-2,4(1H, 3H)-pyrimidinedione] can induce apoptosis in cultured oral cancer cells (D. Tong et al., Oral Oncology 36, 2000 236-241). Further, it is also known that colon cancer has a sensitivity to 5-FU (D. Arango et al., Cancer Research 61, 2001 4910-4915). In the present invention, therefore, the combination of 5-FU having established anti-cancer activity and the compounds of formula (I), especially the compound of general formula (VI) of the present invention is prepared and tested against SW480 cell lines. As a result, it is found that the combination of 5-FU with the compounds of the present invention, especially TCF4 compound, has a remarkable effect for inhibiting cancer cell growth such as SW480 cells.

[0148] Compounds of the present invention have been shown to inhibit the expression of Wnt signaling. Hanai et al., J. Cell Bio. 158:529 (2002), have shown that endostatin, a known anti-angiogenic factor, inhibits Wnt signaling. Accordingly, another aspect of the present invention provides a method of treating or preventing aberrant angiogenesis disease comprising administering to a subject in need thereof a safe and effective amount of a reverse-turn mimetic of the present invention. In one embodiment the invention treats the aberrant angiogenesis disease, i.e., administration of a reverse-turn mimetic of the present invention to a subject having aberrant angiogenesis disease achieves a reduction in the severity, extent, or degree, etc. of the aberrant angiogenesis disease. In another embodiment the invention prevents aberrant angiogenesis disease, i.e., administration of a reverse-turn mimetic of the present invention to a subject that is anticipated to develop new or additional aberrant angiogenesis disease achieves a reduction in the anticipated severity, extent, or degree, etc. of the aberrant angiogenesis disease. Optionally, the subject is a mammalian subject.


[0149] Compounds of the present invention have been shown to inhibit the expression of Wnt signalling. Sen et al., P.N.A.S. (USA) 97:2791 (2000), have shown that mammals with rheumatoid arthritis demonstrate increased expression of Wnt and Fz in RA synovial tissue. Accordingly, another aspect of the present invention provides a method of treating or preventing rheumatoid arthritis disease comprising administering to a subject in need thereof a safe and effective amount of a reverse-turn mimetic of the present invention. In one embodiment the invention treats the rheumatoid arthritis disease, i.e., administration of a reverse-turn mimetic of the present invention to a subject having rheumatoid arthritis disease achieves a reduction in the severity, extent, or degree, etc. of the rheumatoid arthritis disease.

Optionally, the subject is a mammalian subject.


[0150] Compounds of the present invention have been shown to inhibit the expression of Wnt signalling. Uthoff et al., Int. J. Oncol. 19:803 (2001), have shown that differential upregulation of disheveled and fz (Wnt pathway molecules) occurs in ulcerative colitis (compared to Chron's disease patients). Accordingly, another aspect of the present invention provides a method of treating or preventing ulcerative colitis comprising administering to a subject in need thereof a safe and effective amount of a reverse-turn mimetic the present invention. In one embodiment the invention treats the ulcerative colitis, i.e., administration of a reverse-turn mimetic of the present invention to a subject having ulcerative colitis achieves a reduction in the severity, extent, or degree, etc. of the ulcerative colitis.

Optionally, the subject is a mammalian subject.


[0151] Compounds of the present invention have been shown to inhibit Wnt TCF/catenin signalling. Accordingly, another aspect of the invention provides a method of treating or preventing tuberious sclerosis complex (TSC) comprising administering to a subject in need thereof a safe and effective amount of a reverse-turn mimetic the present invention. Subjects having TSC typically develop multiple focal lesions in the brain, heart, kidney and other tissues (see, e.g., Gomez, M. R. Brain Dev. 17(suppl): 55-57 (1995)). Studies in mammalian cells have shown that overexpression of TSC1 (which expresses hamartin) and TSC2 (which expresses tuberin) negatively regulates cell proliferation and induces G1/S arrest (see, e.g., Miloloza, A. et al., Hum. Mol. Genet. 9: 1721-1727 (2000)). Other studies have shown that hamartin and tuberin function at the level of the 13-catenin degradation complex, and more specifically that these proteins negatively regulate beta-catenin stability and activity by participating in the beta-catenin degradation complex (see, e.g., Mak, B. C., et al. J. Biol. Chem. 278(8): 5947-5951, (2003)). Beta-catenin is a 95-kDa protein that participates in cell adhesion through its association with members of the membrane-bound cadherin family, and in cell proliferation and differentiation as a key component of the WntAWingless pathway (see, e.g., Daniels, D. L., et al., Trends Biochem. Sci. 26: 672-678 (2001)). Misregulation of this pathway has been shown to be oncogenic in humans and rodents. The present invention provides compounds that modulate β-catenin activity, and particularly its interactions with other proteins, and accordingly may be used in the treatment of TSC. Thus, in one embodiment the invention treats TSC, i.e., administration of a reverse-turn mimetic of the present invention to a subject having TSC achieves a reduction in the severity, extent, or degree, etc. of the TSC. In another embodiment the invention prevents TSC, i.e., administration of a reverse-turn mimetic of the present invention to a subject that is anticipated to develop new or additional TSC achieves a reduction in the anticipated severity, extent, or degree, etc. of the TSC. Optionally, the subject is a mammalian subject.


[0152] Compounds of the present invention have been shown to inhibit the expression of Wnt signalling. The Kaposi's sarcoma-associated herpesvirus (KSHV) latency-associated nuclear antigen (LANA) is expressed in all KSHV-associated tumors, including Kaposi's sarcoma (KS) and β-cell malignancies such as primary effusion lymphoma (PEL) and multicentric Castleman's disease. Fujimuro, M. et al., Nature Medicine 9(3):300-306 (2003), have shown that LANA acts to stabilize β-catenin, apparently by redistribtution of the negative regular GSK-3 β. The present invention provides compounds and methods for inhibiting β-catenin protein interactions, e.g., β-catenin/TCF complex formation. Thus, the compounds of the present invention thwart the LANA-induced accumulation of β-catenin/TCF complex and, at least in part, the consequences of KSHV infection. Accordingly, another aspect of the present invention provides a method of treating or preventing conditions due to infection by Karposi's sarcoma-associated herpesvirus (KSHV). Such conditions include KSHV-associated tumors, including Kaposi's sarcoma (KS) and primary effusion lymphoma (PEL). The method comprises administering to a subject in need thereof a safe and effective amount of a reverse-turn mimetic the present invention. In one embodiment the invention treats the KSHV-associated tumor, i.e., administration of a reverse-turn mimetic of the present invention to a subject having a KSHV-associated tumor achieves a reduction in the severity, extent, or degree, etc. of the tumor. In another embodiment the invention prevents a KSHV-associated tumor, i.e., administration of a reverse-turn mimetic of the present invention to a subject that is anticipated to develop new or additional KSHV-associated tumors achieves a reduction in the anticipated severity, extent, or degree, etc. of the tumor. Optionally, the subject is a mammalian subject.


[0153] LEF/TCF DNA-binding proteins act in concert with activated β-catenin (the product of Wnt signaling) to transactivate downstream target genes. DasGupta, R. and Fuchs, E. Development 126(20):4557-68 (1999) demonstrated the importance of activated LEF/TCF complexes at distinct times in hair development and cycling when changes in cell fate and differentiation commitments take place. Furthermore, in skin morphogenesis, β-catenin has been shown to be essential for hair follicle formation, its overexpression causing the “furry” phenotype in mice (Gat, U., et al. Cell 95:605-614 (1998) and Fuchs, E. Harvey Lect. 94:47-48 (1999). See also Xia, X. et al. Proc. Natl. Aad. Sci. USA 98:10863-10868 (2001). Compounds of the present invention have been shown to inhibit the expression of Wnt signaling, and interfere with formation of β-catenin complexes. Accordingly, the present invention provides a method for modulating hair growth comprising administering to a subject in need thereof a safe and effective amount of a reverse-turn mimetic the present invention, where the amount is effective to modulate hair growth in the subject. Optionally, the subject is a mammalian subject.


[0154] Alzheimer's disease (AD) is a neurodegenerative disease with progressive dementia. This disease is accompanied by three main structural changes in the brain, namely, i) intracellular protein deposits (also known as neurofibrillary tangles, or NFT), ii) extracellular protein deposits termed amyloid plaques that are surrounded by dystrophic neuritis, and iii) diffuse loss of neurons. Developmental studies have shown that familial forms of AD (FAD)-linked presenilin (PS) proteins function as components in the Notch signal transduction cascase and that β-catenin and GSK-3β are transducers of the Wnt signaling pathway (De Ferrari, G. V. and Inestrosa N. C., Brain Res. Rev. 33(1):1-12, August 2000). Both pathways have been connected through Dishevelled (Dvl) protein, a known transducer of the Wnt pathway, and are thought to have an important role in brain development. See also Hartmann, D. Proc. Natl. Acad. Sci. USA 2001, 98(19):10522-10523. Compounds of the present invention have been shown to inhibit the expression of Wnt signaling, and interfere with formation of β-catenin complexes. Accordingly, the present invention provides a method for treating or preventing Alzheimer's disease (AD) comprising administering to a subject in need thereof a safe and effective amount of a reverse-turn mimetic the present invention, where the amount is effective to treat or prevent AD in the subject. Optionally, the subject is a mammalian subject.
