Studies on the Formulation of Topical Corticosteroids
… were compared with their 21-isomers using esterases from hog liver and mouse skin homogenates. The results showed that the 21-esters were very sensitive to the esterases. Based on the quantitative data on the decomposition of these corticosteroids, it was clearly shown that the …

Evaluation of Surface Acetylated Bacterial Cellulose for Antibacterial Wound Dressing Applications
… were hypothesized to be cleaved by bacterial esterases or other hydrolytic enzymes such that acetic acid, a well-known antibacterial compound, will be produced leading to the death of the bacterial cells. Surface acetylation was confirmed via FTIR and its effect on the morphology of bacterial …
