In Silico Analysis of Selected Mikania Constituents As Human HMG-CoA Reductase, Human Inducible Nitric Oxide Synthase, and Human Squalene Synthase Inhibitory Agents.

Background Numerous pharmacological activities have been reportedin species. In the present investigation, we aimed to evaluate 26 selected constituents of as potent inhibitory agents of human HMG-CoA reductase (hHMGR), human inducible nitric oxide synthase (hiNOS), and human squalene synthase (hSQS) using the in silico method. Methodology Twenty-six selected constituents of were investigated based on the docking behavior of three target enzymes, namely hHMGR, hiNOS, and hSQS, using the Cdocker method (Discovery Studio 3.1, Accelrys, Inc., San Diego, CA). Results Docking analysis showed that methyl-3,5-di--caffeoyl quinate (MCQ) has the maximum binding energy (BE) (-39.63, -50.65, and -58.56 kcal/mol) with hHMGR, hiNOS, and hSQS enzymes. On the other hand, six ligands (kaurenoic acid (KAA), stigmasterol (SS), grandifloric acid (GA), kaurenol (KA), spathlenol (SP), and taraxerol (TA)) of failed to dock with either of the target enzymes (hHMGR, hiNOS, or hSQS). Conclusions The findings of the current study provide new insight regarding 26 selected ligands of as potent inhibitory agents of hHMGR, hiNOS, and hSQS.
