Abstract
BACKGROUND: Aspergillosis, has recently confounded some states of India. Due to major role in fungal cell wall synthesis, in the present study UDP-glycosyltransferase, Glucosamine-6-phosphate synthase and chitin synthase were chosen as an appropriate sites to design drug. The objective of present study was molecular docking of lemon grass essential oil component citral and in vitro validation. GC-FID analysis was used to find out aromatic profile. For docking, Patch-dock analysis was used. Ligand Protein 2D and 3D Interactions were also studied. Drug likeliness, and toxicity profile were also studied. Docking analysis indicated effective binding of citral to UDP-glycosyltransferase, Glucosamine-6-phosphate synthase and chitin synthase. In vitro validation was performed by fungal strain RESULTS: GC-FID profiling revealed the presence of citral as major bioactive compound. Interactions results indicated that, UDP-glycosyltransferase, Glucosamine-6-phosphate synthase and chitin synthase enzymes and citral complexes forms hydrogen and hydrophobic interactions. Citral also depicted drug likeliness by LIPINSKY rule, sufficient level of bioactivity, drug likeliness and toxicity. CONCLUSION: In vitro results revealed that lemon grass oil was able to inhibit growth of fungal strains toxicity thus signifying its role as potent anti-fungal drug.
