The half-lives of the nine model prodrugs in the presence of porcine liver esterase ranged from about 2 min to 190 min. The steric bulkiness of the acyl group seems to have only a very minor effect on the half-lives of the esterase-triggered release of amines from the model prodrugs. The rate of the lactonization depends on the steric and electronic properties of the amine moiety.}, number={4}, journal={BIOORGANIC & MEDICINAL CHEMISTRY}, author={Wang, BH and Zhang, HJ and Zheng, AL and Wang, W}, year={1998}, month={Apr}, pages={417–426} }
