Description générale

A cell-permeable oxazole compound that acts as a selective CRT (β-catenin responsive transcription) inhibitor (IC50 = 8.2 nM against Wnt3a-dependent SuperTopFlash STF16-luc reporter activity in HEK293 cultures) by interfering with β-cat-TCF4 interaction via direct β-catenin (β-cat) binding, while exhibiting much reduced activity against Hedgehog, Jak/Stat, or Notch signaling pathway-dependent transcription activation. Effectively inhibits cellular expression of CRT target genes, including WISP1, AXN2, and CYCD1, in a dose-dependent manner (25 to 75 µM), and selectively inhibits the proliferation of HCT116 (75 µM), HT29 (75 µM), and several primary human colon cancer cultures (6.25 to 100 µg/ml; average IC50 ~36 µg/ml) that require sustained Wnt/CRT activity for survival.

Androgen receptor (AR) is the major therapeutic target in aggressive prostate cancer. However, targeting AR alone can result in drug resistance and disease recurrence. Therefore, simultaneous targeting of multiple pathways could in principle be an effective approach to treating prostate

Misregulated β-catenin responsive transcription (CRT) has been implicated in the genesis of various malignancies, including colorectal carcinomas, and it is a key therapeutic target in combating various cancers. Despite significant effort, successful clinical implementation of CRT inhibitory therapeutics remains a
