Hydrolytic lability
WebOur results provided evidence for the hydrolytic structure lability relationship and demonstrated that the hydrolytic stability in plasma and liver microsome might depend on carboxylesterase activity. Molecular modelling studies were performed in order to understand the experimental data. Websuch conditions because of the extreme hydrolytic lability of the amino groups on the ring which convert over to the hydroxy group. Thus as cited in U.S. Pat. 3,579,528 hy drolysis of one or both of the amino groups will occur dur ing halogenation of 2,6-diaminopyridine in an acid en vironment.
