RESUMO
Elastase is a protease or proteolytic enzyme, responsible for the breakdown of protein. There are eight human genes encoding for elastase, of which Elastase-1 (CELA-1) and Elastase-2 (ELANE) has significant implications on human diseases. Elastase-1 is primarily expressed in skin keratinocytes and is regarded as the major cause for the blistering in bullous pemphigoid, which affects the skin. On the other hand, Elastase-2 (ELANE), is expressed in the azurophil granules of neutrophils, is responsible for pulmonary emphysema and cyclic hematopoiesis a rare genetic disorder. Elastase is also produced by bacteria such as Pseudomonas aeruginosa, and forms the virulent factor in human. The ingredients from essential natural oils were found to have wound healing effects on non-healing wounds that is interfered by elastase due to microbial infection. Essential oils such as citral, citronellal, geranial, geraniol, and thymol were screened for their inhibitory activity on elastase produced by neutrophil, skin, and Pseudomonas aeruginosa by docking and were analyzed for their subcutaneous ADMET properties by ADME - TOX - Web server.
