absorbed P-gp inhibitor) as a starting point for optimization. To aid in the design of these dualinhibitors, we solved the high-resolution cryo-EM structure of encequidar bound to human P-gp. The structure guided us to prudently decorate the encequidar scaffold with CYP3A4 pharmacophores, leading to the identification of several analogues with dual potency against P-gp and CYP3A4. In vivo, dual P-gp and

The aspect of the present application relate to process for the preparation of Encequidar (HM-30181A) and salts thereof. Specific aspects relate to an improved process for the Encequidar and its mesylate salt, comprising the amidation of aniline precursor of Encequidar of formula II using 4-oxo-4H-chromene-2-carboxylic acid in the presence of an activating agent.

rational design and evaluation of novel dual potentinhibitors of P-gp and CYP3A4 using an anthranilamide derivative tariquidar as a starting point for their structural optimizations. Compound bearing -imidazolylbenzyl side chain, was found to have potent and selective P-gp (EC = 28 nM) and CYP3A4 (IC = 223 nM) inhibitory activities with low absorption potential (P (A-to-B) <0.06). , inhibitor improved
