Based on the previously reported lead compound, a series of benzofuran derivatives were prepared to study their antagonistic activities to A2A receptor. The replacement of the phenyl group at the 4-position with a heterocyclic ring improved the PK profile and aqueous solubility. From these studies, we discovered a potent new A2A antagonist, 12a, which has both a good oral bioavailability and in vivo
基于先前报道的先导化合物,制备了一系列苯并呋喃衍生物以研究其对A 2A受体的拮抗活性。用杂环取代4-位的苯基改善了PK曲线和水溶性。从这些研究中,我们发现了一种有效的新型A 2A拮抗剂12a,在MPTP处理的普通mar猴中,它既具有良好的口服生物利用度,又具有体内运动障碍的体内功效。
