FIELD OF INVENTION

The present invention relates to a series of quinoline derivatives, as hedgehog pathway inhibitors, especially as SMO inhibitors, compounds of the present invention can be used in treating diseases relating to hedgehog pathway including cancer.

PRIOR ARTS

Hedgehog proteins are secreted signal proteins originally found in drosophila, they are highly hydrophobic proteins and play a critical role in embryonic development. Three types of homologous hedgehog proteins have already been identified in humans, which are sonic hedgehog (Shh), Indian hedgehog (Ihh) and Desert hedgehog (Dhh) respectively. Thereinto, Shh is not only essential for embryonic development and there are a lot of evidence showing that it also plays an important role in the carcinogenesis mechanism of some cancers including basal cell carcinoma and so on. (Caro, I. and J. A. Low, Clin Cancer Res, 2010. 16 (13): 3335-9). In vivo Shh synthesizes a precursor protein with a molecular weight of 45 kDa, produces a N-terminal fragment with a molecular weight of 20 kDa by self-excision, the N-terminal fragment is of all the known biological activities in vivo, including activating an intracellular hedgehog signaling pathway whose key members embraces patched (PTCH), GPCRs-like receptors oncogene smoothened (SMO) and transcription factor Gli, etc. (Bale, A. E. and K. P. Yu, Hum Mol Genet, 2001. 10 (7): 757-62). Analysis results of the variation in basal cell carcinoma hedgehog signaling pathway show that most of the variation occurs in PTCH-1 and SMO. (Von Hoff, D. D., et al., N Engl J Med, 2009. 361 (12): 1164-72). PTCH-1 is a membrane protein with a 12-transmembrane structure, which is a direct receptor of Shh. In the absence of Shh, PTCH-1 interacts with SMO, which is a 7-transmembrane protein, to inhibit the biological activity of SMO. The binding of Shh and PTCH-1 leads to a removal of PTCH-1 from SMO thereby making SMO loose from being inhibited. Gli transcription factor is controlled by SMO which is as a switch of gene transcription and whose key members include Gli1, Gli2 and Gli3. The whole hedgehog pathway plays an important role in normal embryonic development. Disrupting this signaling pathway will cause serious malformation, the natural teratogenic compound cyclopamine is an example which is a hedgehog inhibitor. Usually, the concentration of hedgehog protein in an adult human body is very low. In the case of low hedgehog protein concentration, PTCH-1 binds to SMO thereby inhibiting the biological activity of SMO, so that the whole pathway is inactive or of very low activity. When the cells secrete hedgehog protein, the binding of hedgehog to the PTCH-1 receptor leads to its removal from SMO, thereby losing inhibition effect on SMO. SMO further activates transcription factor Gli-1 to regulate gene transcription and cell growth. Increasing evidence indicates that the majority of the basal cell carcinoma is caused by overhigh hedgehog signaling pathway activity led by mutations or other causes. Thus, inhibiting the overhigh activity of hedgehog signaling pathway can inhibit the growth of cancer cells so as to achieve the treatment of basal cell carcinoma or other cancers caused by the same mechanism. The evidence that SMO's constitutive activation leads to cancer (e.g. BCC) as well as relieving the inhibition from Ptch makes SMO cause cancer illustrates the use of SMO antagonist as therapeutic agents in the treatment of the diseases (Stone, et al., (1996) Nature 384: 129). A series of scientific and clinical trials show that hedgehog inhibitors are effective in the treatment of many cancers. The latest clinical trial data show that hedgehog inhibitor GDC-0449 is effective in the treatment of basal cell carcinoma and medullary cell carcinoma (Lorusso P M. et al. Clin Cancer Res. 2011; 17 (8): 2502-11), which was licensed by FDA in January 2012, and the other cancers cause by the same mechanism, such as basal cell nevus syndrome (BCNS) (Goldberg L H. et al. Arch Dermatol. 2011 Mar. 21.). Biochemical studies show that the inhibition position of GDC-0449 locates on SMO, inhibiting the activity of SMO means inhibiting the activity of the whole hedgehog pathway, so as to achieve the purpose of anti-cancer. In addition to the two types of cancers, basal cell carcinoma and medullary cell carcinoma, there are many other cancers related to the ultra-high activity of hedgehog signaling pathway, including pancreatic cancer, stomach cancer, colorectal cancer, ovarian cancer and prostate cancer, and part of leukemia etc. (De Smaele E. et al. Curr Opin Investig Drugs. 2010; 11(6): 707-18). Thus, there is a promising prospect of developing hedgehog inhibitors as novel anticancer drugs.

Although there are some SMO inhibitors in the prior art, it still need to be further improved in the aspects of activity, solubility, pharmacokinetics, druggability and so on.

Inoculate the logarithmic growth phase of C3H10T1/2/Gli-Luc cells into a 96-well culture plate with 20000 cells per well, cells were cultured in a 37° C., 5% CO₂ incubator overnight. The next day, the compounds were diluted in the following ways: the positive compound GDC0449 (1 mM) and the compounds (1 mM) to be measured were serially diluted to 7 concentrations by DMSO according to 1:3 and 1:10 respectively, the eighth is for DMSO control, and then diluted with fresh medium 100 times. The medium of the cells cultured overnight was removed, 80 μL fresh culture medium was added per well, then 20 μL gradiently diluted positive compound and compounds to be measured and 100 μL 30 nM Shh-N containing conditioned medium were added, each concentration repeated 2 wells, at the same time, positive and negative reference well were set (i.e. Shh Ctrl: 80 μL fresh medium+20 μL 1% DMSO containing medium+100 μL 30 nM Shh-N containing conditioned medium; Unstimulated Ctrl: 180 μL fresh medium+20 μL 1% DMSO containing medium), cells were cultured in the incubator for further 24 h.

Intracellular luciferase activity detection: take the cells out of 96-well plate, discard the culture medium, the cells were washed with PBS twice, then each well added with 20 μL lysate (Promega E1531), oscillate pyrolysis at room temperature for 30 min. 5 μL cell lysates were transferred to 384-well plate (Greiner 781074), then each well was added with 25 μL luciferase reaction liquid (Promega E1501), after rapid mixed, immediately placed into the VarioSkan Flash multi-function reading instrument to read the relative light units (RLU) value.

Data analysis: using Prism's GraphPad 5 for data analysis. RLU reading to the logarithmic mapping of compound concentration on behalf of luciferase activity, and then curve fitting using the following equation to give IC₅₀ value, Y (RLU)=minimum+(maximum−minimum)/(1+10^(log of compound concentration−Log IC₅₀)).
