Silanediol peptidomimetics have been prepared, designed to inhibit the serine protease enzyme Factor XIa (FXIa) for treatment of thrombosis without complete interruption of normal hemostasis. These Arg-[Si]-Ala analogues of the FXIa substrate (FIX) are the first silanediol dipeptide analogues to carry a basic guanidine group. Control of stereochemistry was accomplished using catalytic asymmetric hydrosilylation and addition of a silyllithium intermediate to the Davis-Ellman sulfinimine.
硅二醇肽拟肽已被制备，旨在抑制丝氨酸蛋白酶酶因子 XIa（FXIa），以治疗血栓而不完全中断正常止血。这些 FXIa 底物（FIX）的 Arg-[Si]-Ala 类似物是第一个带有碱性胍基的硅二醇二肽类似物。使用催化不对称氢化硅烷化和将硅烷基锂中间体加成到戴维斯-埃尔曼亚磺亚胺来控制立体化学。
