The present invention relates generally to the fields of medicine, medicinal chemistry, organic chemistry, and pharmacology.
Human serum response factor (SRF) is a transcription factor which binds to a serum response element (SRE) associated with a variety of genes including proto-oncogenes such as c-fos, fosB, and, junB, and muscle genes such as smooth muscle α- and γ-actins, myosin light chain, and α- and β-myosin heavy chains.
SRF-binding sites were initially identified in growth-related genes. Gene inactivation or knockdown studies in species ranging from unicellular eukaryotes to mice have consistently shown that SRF plays a crucial role in cellular migration and normal actin cytoskeleton and contractile biology.
Cell migration is central to myriad developmental (e.g., gastrulation) and pathological (e.g., metastasis) processes. The actin cytoskeleton, long thought to be a static scaffold for the maintenance of cell shape, polarity, and mechanical support, undergoes dynamic remodeling involving scores of proteins that regulate the cytoskeleton. The driving force for membrane protrusion, one of the first steps in metastasis-associated cellular migration, is localized polymerization of submembrane actin filaments.
Glaucoma is the second leading cause of irreversible blindness and it affects over 70 million people worldwide. In glaucoma, progressive fibrosis and malfunctioning of the trabecular meshwork, in particular the aberrant production of extracellular matrix, leads to increased resistance to aqueous outflow and glaucomatous damage. SRF is involved in the regulation of genes that are involved in a variety of fibrosis phenotypes, including vascular, lung, and ocular fibrosis.
It has been estimated that the transcription of as many as 300 genes is under the control of SRF signaling, and of these, more than 200 are directly targeted by the protein. SRF is therefore integral to a vast number of cellular processes, from metastasis-associated cellular migration, to maintenance of ocular cell matrix dynamics. Given the role of SRF in cell migration and ocular matrix maintenance, inhibition of SRF is a new therapeutic approach for treating aberrant cell growth, metastasis, and glaucoma.
The present disclosure provides compositions and methods for addressing the SRF-mediated disorders discussed above. The inventors have identified a series of novel small organic compounds, referred to herein as remodilins, that are useful for inhibiting SRF activity and affecting the downstream pathways discussed above. The inventors have discovered that these novel remodilins inhibit activation of SRF. By inhibiting a transcription factor that is upstream of these pathologies, the remodilins provide a novel route for inhibiting tumor cell growth, inhibiting migration of cancer cells (metastasis), and treating glaucoma by softening eye cells and inhibiting smooth muscle alpha actin and fibronectin expression.

Other objects, features and advantages of the present invention will become apparent from the following detailed description. It should be understood, however, that the detailed description and the specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
The present invention overcomes the deficiencies of the prior art by providing remodilin compositions that inhibit serum response factor activity. Because serum response factor activity regulates expression of oncogenes, smooth muscle proteins, and cell matrix maintenance proteins, the remodilins disclosed herein provide novel small molecules for treating cancer, metastasis, and glaucoma.
Hypoxia-inducible factor 1-alpha (HIF1a) plays an important role in cellular responses to systemic oxygen levels. The remodilins disclosed herein inhibit TGFb-induced HIF1α accumulation in fibroblasts and inhibit hypoxia-induced accumulation of HIF1a. In clinical settings, remodilins may be used to inhibit hypoxia-induced responses, and may be useful for treating ischemia and hypoxia-related diseases, including sleep apnea. Remodilins also inhibit glycolysis and cellular metabolism.

Prodrugs of the compounds employed in the invention may be prepared by modifying functional groups present in the compound in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent compound.
Accordingly, prodrugs include, for example, compounds described herein in which a hydroxy, amino, or carboxy group is bonded to any group that, when the prodrug is administered to a subject, cleaves to form a free hydroxyl, free amino, or carboxylic acid, respectively. Other examples include, but are not limited to, acetate, formate, and benzoate derivatives of alcohol and amine functional groups; and alkyl, carbocyclic, aryl, and alkylaryl esters such as methyl, ethyl, propyl, iso-propyl, butyl, isobutyl, sec-butyl, tert-butyl, cyclopropyl, phenyl, benzyl, and phenethyl esters, and the like.
It should be recognized that the particular anion or cation forming a part of any salt of this invention is not critical, so long as the salt, as a whole, is pharmacologically acceptable. Additional examples of pharmaceutically acceptable salts and their methods of preparation and use are presented in Handbook of Pharmaceutical Salts: Properties, Selection and Use (2002), which is incorporated herein by reference.
1. Pharmaceutical Formulations and Routes of Administration
Pharmaceutical compositions are provided herein that comprise an effective amount of one or more substances and/or additional agents dissolved or dispersed in a pharmaceutically acceptable carrier. The phrases “pharmaceutical or pharmacologically acceptable” refers to molecular entities and compositions that do not produce an adverse, allergic or other untoward reaction when administered to an animal, such as, for example, a human, as appropriate. The preparation of a pharmaceutical composition that contains at least one substance or additional active ingredient will be known to those of skill in the art in light of the present disclosure, as exemplified by Remington's Pharmaceutical Sciences, 18th Ed.

In any case, the composition may comprise various antioxidants to retard oxidation of one or more component. Additionally, the prevention of the action of microorganisms can be brought about by preservatives such as various antibacterial and antifungal agents, including but not limited to parabens (e.g., methylparabens, propylparabens), chlorobutanol, phenol, sorbic acid, thimerosal, or combinations thereof.
The substance may be formulated into a composition in a free base, neutral or salt form. Pharmaceutically acceptable salts, include the acid addition salts, e.g., those formed with the free amino groups of a proteinaceous composition, or which are formed with inorganic acids such as for example, hydrochloric or phosphoric acids, or such organic acids as acetic, oxalic, tartaric or mandelic acid. Salts formed with the free carboxyl groups can also be derived from inorganic bases such as for example, sodium, potassium, ammonium, calcium or ferric hydroxides; or such organic bases as isopropylamine, trimethylamine, histidine, or procaine.
In embodiments where the composition is in a liquid form, a carrier can be a solvent or dispersion medium comprising but not limited to, water, ethanol, polyol (e.g., glycerol, propylene glycol, liquid polyethylene glycol, etc.), lipids (e.g., triglycerides, vegetable oils, liposomes) and combinations thereof. The proper fluidity can be maintained, for example, by the use of a coating, such as lecithin; by the maintenance of the required particle size by dispersion in carriers such as, for example liquid polyol or lipids; by the use of surfactants such as, for example hydroxypropylcellulose; or combinations thereof such methods. It may be preferable to include isotonic agents, such as, for example, sugars, sodium chloride or combinations thereof.
In other embodiments, one may use eye drops, nasal solutions or sprays, aerosols or inhalants. Such compositions are generally designed to be compatible with the target tissue type. In a non-limiting example, nasal solutions are usually aqueous solutions designed to be administered to the nasal passages in drops or sprays. Nasal solutions are prepared so that they are similar in many respects to nasal secretions, so that normal ciliary action is maintained. Thus, in certain embodiments the aqueous nasal solutions usually are isotonic or slightly buffered to maintain a pH of about 5.5 to about 6.5. In addition, antimicrobial preservatives, similar to those used in ophthalmic preparations, drugs, or appropriate drug stabilizers, if required, may be included in the formulation. For example, various commercial nasal preparations are known and include drugs such as antibiotics or antihistamines.
In certain embodiments the substance is prepared for administration by such routes as oral ingestion. In these embodiments, the solid composition may comprise, for example, solutions, suspensions, emulsions, tablets, pills, capsules (e.g., hard or soft shelled gelatin capsules), sustained release formulations, buccal compositions, troches, elixirs, suspensions, syrups, wafers, or combinations thereof. Oral compositions may be incorporated directly with the food of the diet. In certain embodiments, carriers for oral administration comprise inert diluents, assimilable edible carriers or combinations thereof. In other aspects of the invention, the oral composition may be prepared as a syrup or elixir. A syrup or elixir, and may comprise, for example, at least one active agent, a sweetening agent, a preservative, a flavoring agent, a dye, a preservative, or combinations thereof.
In certain embodiments an oral composition may comprise one or more binders, excipients, disintegration agents, lubricants, flavoring agents, and combinations thereof. In certain embodiments, a composition may comprise one or more of the following: a binder, such as, for example, gum tragacanth, acacia, cornstarch, gelatin or combinations thereof; an excipient, such as, for example, dicalcium phosphate, mannitol, lactose, starch, magnesium stearate, sodium saccharine, cellulose, magnesium carbonate or combinations thereof; a disintegrating agent, such as, for example, corn starch, potato starch, alginic acid or combinations thereof; a lubricant, such as, for example, magnesium stearate; a sweetening agent, such as, for example, sucrose, lactose, saccharin or combinations thereof; a flavoring agent, such as, for example peppermint, oil of wintergreen, cherry flavoring, orange flavoring, etc.; or combinations thereof the foregoing. When the dosage unit form is a capsule, it may contain, in addition to materials of the above type, carriers such as a liquid carrier. Various other materials may be present as coatings or to otherwise modify the physical form of the dosage unit. For instance, tablets, pills, or capsules may be coated with shellac, sugar, or both.
Additional formulations which are suitable for other modes of administration include suppositories. Suppositories are solid dosage forms of various weights and shapes, usually medicated, for insertion into the rectum, vagina, or urethra. After insertion, suppositories soften, melt or dissolve in the cavity fluids. In general, for suppositories, traditional carriers may include, for example, polyalkylene glycols, triglycerides, or combinations thereof. In certain embodiments, suppositories may be formed from mixtures containing, for example, the active ingredient in the range of about 0.5% to about 10%, and preferably about 1% to about 2%.
Sterile injectable solutions are prepared by incorporating the active compounds in the required amount in the appropriate solvent with various of the other ingredients enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the various sterilized active ingredients into a sterile vehicle which contains the basic dispersion medium and/or the other ingredients. In the case of sterile powders for the preparation of sterile injectable solutions, suspensions or emulsion, certain methods of preparation may include vacuum-drying or freeze-drying techniques which yield a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered liquid medium thereof. The liquid medium should be suitably buffered if necessary and the liquid diluent first rendered isotonic prior to injection with sufficient saline or glucose. The preparation of highly concentrated compositions for direct injection is also contemplated, where the use of DMSO as solvent is envisioned to result in extremely rapid penetration, delivering high concentrations of the active agents to a small area.
The composition must be stable under the conditions of manufacture and storage, and preserved against the contaminating action of microorganisms, such as bacteria and fungi. It will be appreciated that endotoxin contamination should be kept minimally at a safe level, for example, less than 0.5 ng/mg protein.
In particular embodiments, prolonged absorption of an injectable composition can be brought about by the use in the compositions of agents delaying absorption, such as, for example, aluminum monostearate, gelatin, or combinations thereof.
2. Combination Therapy
The compositions and methods disclosed herein may be used in combination, i.e., a composition comprising a compound of Formula I may include at least one compound of Formula II and/or at least one additional compound of Formula I. A composition comprising a compound of Formula II may include at least one compound of Formula I and/or at least one additional compound of Formula II.
The compositions and related methods of the present invention, particularly administration of a remodilin of Formula I or Formula II, may also be used in combination with the administration of other glaucoma or cancer therapies. In glaucoma, exemplary treatments include prostaglandins (latanoprost (Xalatan)), travoprost (Travatan Z), tafluprost (Zioptan), bimatoprost (Lumigan) and latanoprostene bunod (Vyzulta); beta blockers timolol (Betimol, Istalol, Timoptic) and betaxolol (Betoptic); alpha-adrenergic agonists apraclonidine (Iopidine) and brimonidine (Alphagan P, Qoliana); carbonic anhydrase inhibitors dorzolamide (Trusopt) and brinzolamide (Azopt); Rho kinase inhibitors netarsudil (rhopressa); and miotic or cholinergic agents pilocarpine (Isopto Carpine).
Cancer therapies also include a variety of combination therapies with both chemical and radiation based treatments. Combination chemotherapies include, for example, cisplatin (CDDP), carboplatin, procarbazine, mechlorethamine, cyclophosphamide, camptothecin, ifosfamide, melphalan, chlorambucil, busulfan, nitrosurea, dactinomycin, daunorubicin, doxorubicin, bleomycin, plicomycin, mitomycin, etoposide (VP16), tamoxifen, raloxifene, estrogen receptor binding agents, taxol, gemcitabien, navelbine, farnesyl-protein tansferase inhibitors, transplatinum, 5-fluorouracil, vincristin, vinblastin and methotrexate, or any analog or derivative variant of the foregoing.
Additional cancer therapies include factors that cause DNA damage, such asas γ-rays, X-rays, and/or the directed delivery of radioisotopes to tumor cells. Other forms of DNA damaging factors are also contemplated such as microwaves and UV-irradiation. It is most likely that all of these factors effect a broad range of damage on DNA, on the precursors of DNA, on the replication and repair of DNA, and on the assembly and maintenance of chromosomes. Dosage ranges for X-rays range from daily doses of 50 to 200 roentgens for prolonged periods of time (3 to 4 wk), to single doses of 2000 to 6000 roentgens. Dosage ranges for radioisotopes vary widely, and depend on the half-life of the isotope, the strength and type of radiation emitted, and the uptake by the neoplastic cells.
Additional cancer therapies that may be used in combination with remodelins include immunotherapeutics that rely on the use of immune effector cells and molecules to target and destroy cancer cells. The immune effector may be, for example, an antibody specific for some marker on the surface of a tumor cell. The antibody alone may serve as an effector of therapy or it may recruit other cells to actually effect cell killing. The antibody also may be conjugated to a drug or toxin (chemotherapeutic, radionuclide, ricin A chain, cholera toxin, pertussis toxin, etc.) and serve merely as a targeting agent. Alternatively, the effector may be a lymphocyte carrying a surface molecule that interacts, either directly or indirectly, with a tumor cell target. Various effector cells include cytotoxic T cells and NK cells.
Inducers of cellular proliferation may be used in combination with remodelins. The proteins that induce cellular proliferation further fall into various categories dependent on function. The commonality of all of these proteins is their ability to regulate cellular proliferation. For example, a form of PDGF, the sis oncogene, is a secreted growth factor. Oncogenes rarely arise from genes encoding growth factors, and at the present, sis is the only known naturally-occurring oncogenic growth factor. In one embodiment of the present invention, it is contemplated that anti-sense mRNA directed to a particular inducer of cellular proliferation is used to prevent expression of the inducer of cellular proliferation.
Inhibitors of cellular proliferation may be used in combination with remodelins. The tumor suppressor oncogenes function to inhibit excessive cellular proliferation. The inactivation of these genes destroys their inhibitory activity, resulting in unregulated proliferation. Exemplary tumor suppressors include p53, p16 and C-CAM.
The compositions and related methods of the present invention may be used in combination with therapies that regulate cell death (apoptosis), by inducing apoptosis. Apoptosis, or programmed cell death, is an essential process for normal embryonic development, maintaining homeostasis in adult tissues, and suppressing carcinogenesis (Kerr et al., 1972). The Bcl-2 family of proteins and ICE-like proteases have been demonstrated to be important regulators and effectors of apoptosis in other systems. The Bcl-2 protein, discovered in association with follicular lymphoma, plays a prominent role in controlling apoptosis and enhancing cell survival in response to diverse apoptotic stimuli (Bakhshi et al., 1985; Cleary and Sklar, 1985; Cleary et al., 1986; Tsujimoto et al., 1985; Tsujimoto and Croce, 1986). The evolutionarily conserved Bcl-2 protein now is recognized to be a member of a family of related proteins, which can be categorized as death agonists or death antagonists. Subsequent to its discovery, it was shown that Bcl-2 acts to suppress cell death triggered by a variety of stimuli. Also, it now is apparent that there is a family of Bcl-2 cell death regulatory proteins which share in common structural and sequence homologies. These different family members have been shown to either possess similar functions to Bcl-2 (e.g., BclXL, BlcW, BlcS, Mcl-1, A1, Bfl-1) or counteract Bcl-2 function and promote cell death (e.g., Bax, Bak, Bik, Bim, Bid, Bad, Harakiri).
Compounds discussed herein may precede, be co-current with and/or follow the other agents by intervals ranging from minutes to weeks. In embodiments where the agents are applied separately to a cell, tissue or organism, one would generally ensure that a significant period of time did not expire between the time of each delivery, such that the agents would still be able to exert an advantageously combined effect on the cell, tissue or organism. For example, in such instances, it is contemplated that one may contact the cell, tissue or organism with two, three, four or more modalities substantially simultaneously (i.e., within less than about a minute) as the candidate substance. In other aspects, one or more remodilins may be administered or provided within 1 minute, 5 minutes, 10 minutes, 20 minutes, 30 minutes, 45 minutes, 60 minutes, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 9 hours, 10 hours, 11 hours, 12 hours, 13 hours, 14 hours, 15 hours, 16 hours, 17 hours, 18 hours, 19 hours, 20 hours, 21 hours, 22 hours, 22 hours, 23 hours, 24 hours, 25 hours, 26 hours, 27 hours, 28 hours, 29 hours, 30 hours, 31 hours, 32 hours, 33 hours, 34 hours, 35 hours, 36 hours, 37 hours, 38 hours, 39 hours, 40 hours, 41 hours, 42 hours, 43 hours, 44 hours, 45 hours, 46 hours, 47 hours, 48 hours, 1 day, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 8 days, 9 days, 10 days, 11 days, 12 days, 13 days, 14 days, 15 days, 16 days, 17 days, 18 days, 19 days, 20 days, 21 days, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 7 weeks, or 8 weeks or more, and any range derivable therein, prior to administering a different glaucoma, anti-proliferative, or anti-metastatic therapeutic. In some embodiments, more than one course of therapy may be employed. It is contemplated that multiple courses may be implemented.
Methods can involve cells, tissues, or organs involving the heart, lung, kidney, liver, bone marrow, pancreas, skin, bone, vein, artery, cornea, blood, small intestine, large intestine, brain, spinal cord, smooth muscle, skeletal muscle, ovary, testis, uterus, and umbilical cord.
Moreover, methods can be employed in cells of the following type: platelet, myelocyte, erythrocyte, lymphocyte, adipocyte, fibroblast, epithelial cell, endothelial cell, smooth muscle cell, skeletal muscle cell, endocrine cell, glial cell, neuron, secretory cell, barrier function cell, contractile cell, absorptive cell, mucosal cell, limbus cell (from cornea), stem cell (totipotent, pluripotent or multipotent), unfertilized or fertilized oocyte, or sperm.
TGFβ plays a key role in promoting breast cancer metastasis, and both anti-TGFβ antibodies and pharmacological inactivation of the TGFβ receptor inhibit experimental breast cancer metastasis in mice. Antibodies and small-molecule TGFβ receptor antagonists inhibit TGFβ function globally, thereby preventing TGFβ from exerting its beneficial physiological activities at sites unrelated to the cancer or its metastases.
A new class of small molecules termed remodilins affect some downstream targets of TGFβ cell stimulation (e.g., activation of serum response factor SRF) without affecting proximal TGFβ cell signaling. Importantly, remodilins blunt the invasive and migratory capabilities of human triple negative breast cancer cells in vitro, and they blunt TGFβ-stimulated myofibroblast transformation, a process associated with fibroblast metastasis-promoting capability. Given the role of SRF in cell migration, inhibition of SRF is a new therapeutic approach for treating aberrant cell growth and metastasis.
In certain aspects, a composition comprising at least one remodelin as disclosed herein may be administered to treat a cancer. The cancer may be a solid tumor, metastatic cancer, or non-metastatic cancer. In certain embodiments, the cancer may originate in the bladder, blood, bone, bone marrow, brain, breast, colon, esophagus, duodenum, small intestine, large intestine, colon, rectum, anus, gum, head, kidney, liver, lung, nasopharynx, neck, ovary, prostate, skin, stomach, testis, tongue, or uterus.

The aqueous humor of primary open angle glaucoma (POAG) patients contains an elevated level of transforming growth factor β2 (TGF-β2) as compared with controls. In perfused human anterior segments, TGF-β2 causes a decrease in outflow facility and an increase in intraocular pressure (IOP). The effects of TGF-β2 were further confirmed in murine models where outflow facility is decreased and IOP increased after adenoviral gene transfer of active human TGF-β2. TGF-β2 is known to activate pro-fibrogenic activities in many parts of the body including trabecular meshwork (TM) cells. In TM cells, TGF-β2 induces elevated expression of extracellular proteins (collagen, fibronectin and laminin) and contractile proteins like alpha-smooth muscle actin (α-SMA). TGF-β2 also induces pro-fibrogenic activities in SC cells and these profibrogenic activities likely make SC cells stiffer. In POAG, the increased stiffness of SC cells has been shown to be correlated with reduced pore formation in SC inner walls and concomitantly increased outflow resistance. Taken together, elevation of TGF-β2 has detrimental effects on aqueous humor outflow likely through pro-fibrogenic activations of TM cells and SC cells. By inhibiting pro-fibrogenic activation by TGF-β2, TGF-β2-induced decreases in outflow facility can be prevented and those structural changes made by TGF-β2 potentially reversed.
A novel class of small molecules (remodilins) inhibit TGF-β1 induced myofibroblast differentiation in vitro in human lung fibroblasts and human airway smooth muscle cells. In murine models in vivo, these remodilins mitigate airways hyperresponsiveness and inhibit aberrant airway remodeling.

All air or moisture sensitive reactions were performed under positive pressure of nitrogen with oven-dried glassware. Chemical reagents and anhydrous solvents were obtained from commercial sources and used as-is. Preparative purification was performed on a Waters semi-preparative HPLC. The column used was a Phenomenex Luna C18 (5 micron, 30×75 mm) at a flow rate of 45 mL/min. The mobile phase consisted of acetonitrile and water (each containing 0.1% trifluoroacetic acid). A gradient of 10% to 50% acetonitrile over 8 minutes was used during the purification. Fraction collection was triggered by UV detection (220 nm). Analytical analysis for purity was determined by a Final QC Method:
Final QC Method analysis was performed on an Agilent 1260 with a 7 minute gradient of 4% to 100% acetonitrile (containing 0.025% trifluoroacetic acid) in water (containing 0.05% trifluoroacetic acid) over 8 minute run time at a flow rate of 1 mL/min. A Phenomenex Luna C18 column (3 micron, 3×75 mm) was used at a temperature of 50° C. Purity determination was performed using an Agilent Diode Array Detector. Mass determination was performed using an Agilent 6130 mass spectrometer with electrospray ionization in the positive mode. All of the analogues for assay have purity greater than 95% based on both analytical methods. 1H and 13C NMR spectra were recorded on a Varian 400 (100) MHz spectrometer. High resolution mass spectrometry was recorded on Agilent 6210 Time-of-Flight LC/MS system. Method A: Amide coupling via acid chloride intermediate
4-Bromo-3-iodobenzoic acid (0.25 g, 0.77 mmol), and oxalyl chloride (0.09 ml, 0.99 mmol) was stirred in DCM (5.00 mL) at room temperature (rt) before adding DMF (2.96 μl, 0.04 mmol) slowly. The mixture was stirred at rt for 72 h, at which time the reaction was concentrated to a white solid. The acid chloride product was reacted with 4-(pyrrolidin-1-ylsulfonyl)aniline to afford the amide product. An alternative reaction entails refluxing 1 equivalent of carboxylic acid with 1.2 equivalents of PCl5 in CHCl3 (1.0 mL). This reaction mixture is refluxed for 3 h then cooled and concentrated. This mixture is used neat for the acid chloride-amine coupling reaction.
Method B: Negishi coupling of organozinc and aryl halide
Method C: Sulfonamide formation by reaction with sulfonyl chloride intermediate, acetamide hydrolysis, and reaction between resulting amine and aromatic acid chloride
Method D: Sulfonamide formation by reaction with sulfonyl chloride intermediate, reduction of nitro to amine, and reaction between resulting amine and aromatic acid chloride
4-amino-N,N-diethylbenzenesulfonamide (0.35 mmol), in DIPEA (1.00 mmol) was stirred at rt in DCM (1.0 mL) before a 1 M solution of 3-iodo-4-methoxybenzoyl chloride (0.42 mL, 0.42 mmol) in DCM was added.

Remodilins 4, 39, 50, and 83 were found to blunt TGFβ-stimulated transformation of human lung-derived fibroblasts to the fibrosis-promoting myofibroblast phenotype in a dose-dependent fashion (
In cultured human lung fibroblasts, remodilins act downstream of Smad signaling, which remains intact, though TGFβ-induced SRF activation is blocked (
TGFβ plays a role in breast cancer metastasis, and remodilins suppress aspects of TGFβ signaling related to cytoskeletal function. The effect of remodilins on the invasive and migratory properties of in vitro breast cancer cells was examined.
Remodilins 39 and 83 each slowed the invasion of triple negative MDA-MB-231 human breast cancer cells from spheroids into a surrounding collagen gel (
Remodilin in vivo pharmacokinetics (PK)
The in vivo bioavailability, plasma half-life, Cmax, and area under the curve (AUC) were determined after administration of single 10 mg/kg doses of remodilins 39 and 83 to mice (Table 1). Selected tissue concentrations of remodilins 39 and 83 after single oral doses of 10 or 50 mg/kg (
By contrast, remodilin 39 exhibits lower oral bioavailability and has a short plasma half-life, but it is distributed much more uniformly across tissues. Even with its longer half-life, single oral doses of remodilin 83 did not maintain tissue or plasma levels above 10 μM throughout the day (
Remodilin 83 is lipophilic and is readily dissolved in either 20% Solutol (macrogol [15]-hydroxystearate, polyethylene glycol [15]-hydroxystearate, polyoxyethylated 12-hydroxystearic acid, Kolliphor; Solutol is a clinically acceptable excipient) or DMSO. In the experiments corresponding to
This study is replicated in female Balb/c including a measurement of mammary fat pad remodilin 83 levels, and doses of 30, 40, and 50 mg/kg BID IP to confirm results of
The experimental procedure examines remodilin effects on three mice at each timepoint (immediately before and 2 hrs after the last dose), all on day 14 of the dosing regimen. The use of 3 mice at each timepoint/condition allows for identification of outlier datapoints while minimizing animal use and cost.
Mouse 4T1.2luc3 cells, which are stably transduced with the firefly luciferase gene, are used for syngeneic injection into syngeneic Balb/c mice; human MDA-MB-436 cells harboring firefly luciferase are injected into athymic nude mice. These highly metastatic cell lines lack expression of estrogen and progesterone receptors and of HER2 (EGFR2) and mimic “triple negative” breast cancer.
5×105 mouse or 2×106 human tumor cells are injected into the fourth left mammary fat pad of lightly anesthetized mice. Tumor volumes are measured by caliper twice per week and calculated as volume=(π/6)×width2×length; tumor growth is monitored by Xenogen imaging weekly (as the tumor cells harbor luciferase). All mice receive luciferin (luciferase substrate; 100 μL of 15 mg/mL solution IP) 15 minutes prior to Xenogen bioluminescence imaging. Experiments continue for 6 weeks to allow for development of lung, liver, and bone metastasis.
In mice exhibiting excessive tumor growth and morbidity, the primary tumor is be excised (on the same day from all animals in both remodilin-treated and vehicle-treated parallel groups) and experiments continue until mouse sacrifice at 6 weeks. At the time of sacrifice or earlier excision, primary tumor size, vascularization, and evidence of local invasion is evaluated by gross and microscopic pathology examination. In mice where remodilins inhibit primary tumor growth, then 106 cancer cells are given to additional mice by tail vein or left ventricular injection to induce lung or bone metastases, respectively.
At the time of sacrifice 6 weeks after tumor cell implantation, intravasation is assessed by assessing the relative abundances of circulating tumor cells. For human cancer cells, the human and mouse isoforms of GAPDH provide relative markers of intravasated tumor and endogenous circulating leukocytes, respectively; these are quantified by real-time PCR, using the ΔΔCt method. For mouse cancer cells, a distinguishing feature is the luciferase gene with which they are transduced (the human cells also have this); as such, the relative blood abundances of firefly luciferase and mouse GAPDH RNAs are measured by real-time PCR to reveal intravasation intensity. Comparison between human GAPDH/mouse GAPDH and luciferase/mouse GAPDH results in xenografted is be used to validate the latter method. Weekly Xenogen imaging, as described above, is used to monitor the growth of distant metastases in lung, liver, and bone. At the time of sacrifice, these organs and brain are examined for metastasis by gross inspection (after inflation with and fixation in Bouin's solution to highlight lung metastases and by bisection of each organ to allow for gross visual identification) and by microscopic quantification, incorporating methods of quantitative stereology to estimate total metastatic volume. Histologic features of metastases are also examined to reveal any potential differences between remodilin-vs vehicle-treated mice. Treatment with remodilin or its corresponding vehicle/delivery control are initiated 2 days prior to tumor cell implantation, in order to ensure that remodilin is present throughout the potential metastasis development period.
In primary open angle glaucoma (POAG) patients, the aqueous humor contains an elevated level of transforming growth factor β2 (TGF-β2) as compared with normal. TGF-β2 activates fibrogenic activities of two key cell types in conventional outflow pathway: trabecular meshwork (TM) cells and Schlemm's canal endothelial (SC) cells. In both TM and SC cells, TGF-β2 induces elevated expression of extracellular proteins (collagen, fibronectin and laminin) and contractile protein such as alpha-smooth muscle actin (α-SMA). These changes in extracellular matrix and contraction in conventional outflow pathway decrease outflow facility and thus elevate intraocular pressure. A novel class of small molecules (remodilins) inhibit TGF-β1 induced myofibroblast differentiation in vitro in human lung fibroblasts and human airway smooth muscle cells. The effect of remodilins on inhibition of TGF-β2 induced fibrogenic activities in the human outflow pathway is examined below.
In POAG, the increased resistance to aqueous humor outflow may be caused by increased extracellular matrix deposition by TM cells, leading to increased TM stiffness, and such fibrogenic change in trabecular meshwork is likely controlled by TGF-β2 pathways. Remodilins' effect on inhibiting fibrogenic activities in TGF-β2 treated TM cells was examined. Two different remodilins in TGF-β2 treated TM cells isolated from a normal post-mortem eye were examined. Expression of extracellular matrix proteins (collagen, fibronectin, laminin) and contractile protein (α-SMA) together with cellular contractile force were examined.
TM cells were cultured in 6-well plates and serum-deprived for one day before drug treatment. Cells were treated with prostaglandin E2 (PGE2, 1 μM), remodilin [3 μM] or vehicle control (dimethyl sulfoxide, DMSO) together with human recombinant TGF-β2 [5 ng/mL] for 48 hours. PGE2 was chosen as a positive control due to its known anti-fibrogenic effects. Compared to no treatment group, TGF-β2 treatment alone elevated α-SMA expressions and pre-treatment of PGE2 inhibited α-SMA expression induced by TGF-β2. Remodilin treatment inhibited α-SMA expression induced by TGF-β2 (
Remodilins' effect on SC cells, another key cell type in conventional outflow pathway, was examined. As described above, TGF-β2 also promotes pro-fibrogenic activation in SC cells and such activation accompanies elevation of cell contraction. Protein expression in TGF-β2 treated SC cells was examined first. SC cells from two different donors were cultured in 6-well plates and serum-deprived for 1 day before drug treatment. Cells were treated with Remodilin [3 or 0 μM] or DMSO together with human recombinant TGF-β2 [2.5 ng/mL] for 48 hours. Compared to no treatment, TGF-β2 treatment induced elevated expression of fibronectin, a key extracellular matrix protein secreted by SC cells. Pre-treatment of remodilins partially inhibited fibronectin expression in TGF-β2 treated SC cells (
Remodilins' effect on elevation of SC cell contraction by TGF-β2 treatment was then examined. Cellular contractile force was measured using Fourier-Transform Traction Microscopy. Compared to no treatment, TGF-β2 treatment elevated average cellular contractile force by almost seven-fold. When SC cells were pre-treated with three different remodilins, remodilins partially inhibited the elevation of contractile force in TGF-β2 treated SC cells in a dose dependent manner (
Remodilins Inhibit Pathways Regulated by Hypoxia-Inducible Factor-1 Alpha (HIF1α) in TGF-Beta (TFGβ)-Stimulated Human Airway Myocytes
RNAseq analysis suggested that remodilins inhibit pathways regulated by hypoxia-inducible factor-1 alpha (HIF1α) in TGF-beta (TFGP)-stimulated human airway myocytes. The influence of remodilin 83 on HIF-1α accumulation in TGFβ-treated fibroblasts was examined. As shown in
In light of the ability of remodilins to inhibit TGFβ-induced and hypoxia-induced HIF1α accumulation, and in light of additional RNAseq data suggesting that remodilins can inhibit glycolytic pathways, the effect of remodilin 83 on oxygen consumption rate (OCR,
Together, the results in
OSA is a chronic, morbid disease affecting about 10% of the adult population, in which frequent episodes of upper airway collapse obstruct inspiratory airflow and cause IH. These episodes of IH disrupt sleep but perhaps more importantly accelerate multiple cardiometabolic abnormalities, including systemic hypertension, cardiovascular disease, stroke, and abnormal glucose metabolism. Therefore, remodilins were examined for their ability on inhibit hypoxia-induced accumulation of HIF1α, a transcription factor that mediates many of the adverse responses to IH. The experiments represented in
Remodilins were tested for their ability to inhibit the systemic hypertension induced in rats subjected to IH in vivo. As depicted in
Adverse cardiometabolic consequences of OSA are treated individually and without specific accounting for the fact that they are promoted (or entirely induced) by the intermittent hypoxia caused by OSA. Hypertension in OSA is treated with antihypertensives, cardiovascular disease prevention follows standard of care (statins, etc) to prevent heart disease and stroke, and glucose intolerance is treated with anti-hyperglycemics, including insulin. Critically, none of these current treatments addresses their more root cause in OSA—that is, the abnormal HIF1α accumulation and signaling induced by intermittent hypoxia. Remodelins may be used to blunt OSA/IH-induced HIF1α accumulation and signaling by interrupting the common pathogenetic pathway upstream of each of these cardiometabolic disturbances. Remodelins may therefore be used to prevent the induction of multiple disorders that currently require multiple drugs.
In vitro, remodilins inhibit serum response factor (SRF) activation by TGFβ, inhibit TGFβ-induced myofibroblast transformation (MFT), and inhibit proximal TGFβ-Smad signaling in breast cancer cells (not in fibroblasts). TGFβ facilitates breast cancer metastasis at multiple key steps including MFT, and SRF is overexpressed in multiple breast cancer types and contributes to sternness.
To test whether remodilins inhibit SRF activation in vivo, the effects of remodilins on luciferase expression (monitored by Xenogen imaging) in 4T1.2 and MDA-MB-436 tumors harboring a SRF-luc transgene (whose luciferase expression depends solely on SRF activity) will be compared to that of tumors in other mice created from corresponding breast cancer cells that constitutively express luciferase. Greater inhibition of SRF-dependent luciferase expression by remodilins would demonstrate their in vivo suppression of SRF activity. Mice will receive a remodilin (39 or 83) or its corresponding vehicle as control. Tumors, metastases, and surrounding tissues will be immunostained for MFT to determine whether modulation of MFT signaling contributes to remodilin effects in vivo. Primary tumors, metastases, and surrounding tissues will be immunostained for Smad4 to determine whether and in which cells Smad4 has translocated to the nucleus (reflecting active proximal TGFβ signaling) and for smooth muscle 3-actin as a marker of myofibroblast transformation, and scored semi-quantitatively for relative expression on a 0-4 scale. Immunostaining for 3-actin will be examined to allow detection and control for any non-specific effect of remodilin treatment.
