Semicarbazones 126-141 cytokine like 1 Homo sapiens 102-106 941194-2 1976 Hydrolysis can be achieved without rearrangement by 1) formation of a C-17 semicarbazone, 2) alkaline removal of the acetate group, and 3) removal of the semicarbazone group in the presence of pyruvic acid-acetic acid. Semicarbazones 75-88 cytokine like 1 Homo sapiens 70-74
