A new class of lymphocyte function-associated antigen-1 (LFA-1) antagonists is described. Elaboration of the 2,3-dihydro-1H-pyrrolizin-5(7aH)-one scaffold resulted in the synthesis of potent inhibitors of the LFA-1/ICAM-1 interaction. Along with the in vitro activity, we present the X-ray crystal structure of the complex of compound 9b, in a novel binding mode to the I-domain of LFA-1.
描述了一种新型的淋巴细胞功能相关抗原-1(LFA-1)拮抗剂。精心制作的2,3-二氢-1H-吡咯嗪-5(7aH)-一个支架可合成LFA-1 / ICAM-1相互作用的有效抑制剂。随着体外活性,我们提出了化合物9b的复合物的X射线晶体结构,其以新颖的结合方式与LFA-1的I结构域结合。
