Structures of enactins Ia, Ib1, Ib2 and Va were determined by spectroscopic studies using their bis-2,4-dinitrophenyl derivatives. Both enactins and neoenactins contain L-serine to form the hydroxamic acid structure. Their physico-chemical and biological properties are closely related. The structures of neoenactin congeners have been previously reported and enactins Ia and Va are proved to be 19-hydroxyneoenactin B2 and 14-dihydroneoenactin M1, respectively. Both enactins Ib1 and Ib2 are determined to be 19-hydroxyneoenactin B1 and considered to be diastereoisomers at the 19-position, though their steric structures at this position remain to be determined.
