WebMay 1, 2001 · Captopril has a sulfhydryl group, fosinopril has a phosphinyl group, and all of the others have a carboxyl group. The differences in the binding groups lead to variations among the agents. For example, the sulfhydryl group on captopril is believed to be the cause of hypersensitivity reactions. WebThe N-phosphinyl group enabled the product purification to be performed simply by washing crude product with EtOAc and hexane. This reaction joined other eight GAP (Group … WebThe phosphinyl group bridges the two zinc ions using two of its three oxygen atoms to coordinate the metal ions. The third oxygen of the phosphonate portion forms a hydrogen bond to a terminal guanidino nitrogen ~h2! of theArg166 side chain. In addition, the binding mode of PAA is also charac- curlhighland.com
