WebHere, using ring-closing metathesis, we substitute the A6-A11 disulfide bond of insulin with a rigid, non-reducible dicarba linkage, yielding two distinct stereo-isomers (cis and trans). Remarkably, only the cis isomer displays full insulin potency, rapidly lowering blood glucose in mice (even under insulin-resistant conditions). normal amylase and elevated lipaseWebThe AlH 2 unit is pseudo-tetrahedral, with the N(3)–Al(1) bond longer than N(4)–Al(1), suggesting some dative bonding character from the lone pair on N(3) to the empty orbital of Al(1).
