  Discovery of CS-2100, a potent, orally active and S1P3-sparing S1P1 agonist

  摘要：

  S1P(3)-sparing S1P(1) agonists have attracted attention as a suppressant of autoimmunity with reduced side effects. Our synthetic efforts and extensive SAR studies led to the discovery of 10b named CS-2100 with the EC50 value of 4.0 nM for human S1P(1) and over 5000-fold selectivity against S1P(3). The in vivo immunosuppressive efficacy was evaluated in rats on host versus graft reaction and the ID50 value was determined at 0.407 mg/kg. The docking studies of CS-2100 with the homology model of S1P(1) and S1P(3) showed that the ethyl group on the thiophene ring of CS-2100 was sterically hindered by Phe263 in S1P(3), not in the case of Leu276 in S1P(1). This observation gives an explanation for the excellent S1P(3)-sparing characteristic of CS-2100. (C) 2011 Elsevier Ltd. All rights reserved.

  Novel cyclic peptide derivatives based on ogipeptins A, B, C, and D were synthesized. Starting with a mixture of ogipeptins A–D, a practical four-step synthetic procedure was followed to prepare novel derivatives with various kinds of acyl side chains. Among the 45 new synthetic derivatives identified, the antibacterial activities of compounds 8-3 and 8-38 were comparable with those of ogipeptin A

  合成了基于 ogipeptins A、B、C 和 D 的新型环肽衍生物。从 ogipeptins A-D 的混合物开始，遵循实用的四步合成程序来制备具有各种酰基侧链的新型衍生物。中标识的45个新的合成衍生物，化合物的抗菌活性8-3和8-38分别与ogipeptin A的可比较的在体外肾毒性使用LLC-PK1细胞的筛选中，化合物8-3和8-38显示显著下细胞毒性 (LD 20 > 480 μM) 高于粘菌素 (LD 20 = 44.2 μM)。
