Development of Scalable Syntheses of Selective PI3K inhibitors
摘要:
On the basis of a more practical and scalable route to an iodothiophene, an efficient and reliable synthesis has been developed for three selective PI3K inhibitors. From this advanced intermediate, the three title compounds were each prepared in five additional steps. Key learnings also include: high throughput experimentation (HTE) screening toward a more robust Suzuki coupling, a more efficient triazole synthesis, and an acid/base cleanup developed to purify the final compounds. The final enabled synthesis required no column chromatography.

HighlyselectivePI3Kinhibitors with subnanomolar PI3Kα potency and greater than 7000-fold selectivity against mTOR kinase were discovered through structure-based drug design (SBDD). These tetra-substituted thiophenes were also demonstrated to have good in vitro cellular potency and good in vivo oralantitumoractivity in a mouse PI3K driven NCI-H1975 xenograft tumor model. Compounds with the desired
