Synthesis and SAR study of modulators inhibiting tRXRα-dependent AKT activation
摘要:
RXR alpha represents an intriguing and unique target for pharmacologic interventions. We recently showed that Sulindac and a designed analog could bind to RXR alpha and modulate its biological activity, including inhibition of the interaction of an N-terminally truncated RXR alpha (tRXR alpha) with the p85 alpha regulatory subunit of phosphatidylinositol-3-OH kinase (PI3K). Here we report the synthesis, testing and SAR of a series of novel analogs of Sulindac as potential modulators for inhibiting tRXR alpha-dependent AKT activation. A new compound 30 was identified to have improved biological activity. (C) 2013 Elsevier Masson SAS. All rights reserved.
A novel acid/base-co-catalyzed formal Baeyer–Villiger oxidation of various ketones using O2 as the sole oxidant under metal-free conditions has been developed for the first time. The reaction tolerates a wide range of ketones and anilines and provides a simple and efficient method for the construction of various amides and isoquinolin-1-ones from the reactions of ketones with anilines in a single step
Getting some closure: Mechanistic studies supported the participation of an oxanickelacycle complex in the hydroacylation step of the title reaction, which proceeds without decarbonylation even in the absence of well‐known chelation assistance by heteroatoms.

plays an important role in many biological and pathological processes. The nongenomic action of RXRα is implicated in many cancers. K-8008, a non-canonical RXRα ligand derived from sulindac, inhibits the TNFα-activated PI3K/AKT pathway by mediating the interaction between a truncated form of RXRα (tRXRα) and the p85α regulatory subunit of PI3K and exerts potent anticancer activity in animal model.
