Analysis of Selected Four-Leaf Water Clover ( species) Constituents as Human Acetyl Cholinesterase (hAchE), Carbonic Anhydrase II (hCA-II), and Protein Tyrosine Phosphatase 1B (PTP1B) Inhibitory Agents.

A four-leaf water clover ( species) has been reported to exhibit various biological activities. In the present study, we aimed to evaluate 23 selected constituents of a four-leaf water clover ( species) as potent inhibitory agents of human acetyl cholinesterase (hAchE), carbonic anhydrase II (hCA-II), and protein tyrosine phosphatase 1B (hPTP-1B) using an method. The 23 selected constituents of the four-leaf water clover ( species) were studied on the docking behavior of hAchE, hCA-II, and hPTP-1B by using the Webina docking method. In addition to docking, toxicity analysis was also performed using the pkCSM web server. Toxicity analysis has shown that 10 ligands (44%) of the four-leaf water clover ( species) were predicted to have hERG II (human ether-a-go-go-related gene) inhibition activity. The docking analysis showed that marsilin has exhibited the maximum binding energy (-11.3 kcal/mol) with the hAchE, whereas it fails to dock with both the target enzymes (hCA-II and hPTP-1B). Thus, the present find provides a new understanding about the 23 selected ligands of the four-leaf water clover ( species) as potent inhibitory agents of human acetyl cholinesterase (hAchE), carbonic anhydrase II (hCA-II), and protein tyrosine phosphatase 1B (hPTP-1B).
