Bioisosteric replacement of anilide with benzoxazole: potent and orally bioavailable antagonists of VLA-4
摘要:
We have designed and synthesized a series of heterocyclic bioisosteres for an anilide based on molecular modeling. Excellent potency was retained in the benzoxazole and the benzimidazole derivatives, where a hydrogen bond acceptor is appropriately positioned to mimic the amide bond oxygen. The deletion of the hydrogen bond donor (N-H) led to improved lipophilicity and bioavailability. In the process, 9a was identified as a potent, specific, and bioavailable VLA-4 antagonist, while 9c was found to be a potent and bioavailable dual antagonist of VLA-4 and alpha(4)beta(7).
