BBO-10203 is an orally active small molecule, also designated as Compound 758, that functions as a selective PI3Kα-Ras interaction disruptor by binding to the Ras-binding domain of PI3Kα. BBO-10203 effectively prevents Ras-PI3Kα complex formation, inhibits downstream Akt activation without altering basal PI3Kα kinase activity, thereby minimizing risks of hyperglycemia and hyperinsulinemia, and displays selective antitumor activity against KRAS-mutant malignancies, making it an important investigational candidate for targeted cancer therapeutics.
