CCR5 Antagonists: 3-(Pyrrolidin-1-yl)propionic Acid Analogues with Potent Anti-HIV Activity
摘要:
graphicA novel approach to alpha,alpha-disubstituted-beta-amino acids (beta(2,2)-amino acids) was employed in the synthesis of a series of 3-(pyrrolidin-1-yl)-propionic acids possessing high affinity for the CCR5 receptor and potent anti-HIV activity. The rat pharmacokinetics for these new analogues featured higher bioavailabilities and lower rates of clearance as compared to cyclopentane 1.
