Insilico Characterization and Antifungal Activity of Curcuma Longa on DNA Topoisomerases of Candida Auris

Abstract

C.auris is now an emerging and opportunistic pathogen with serious ailments both in terms of disease progression and increasing resistance to current antifungals.Topoisomerase I and II were actively used by the strain to multiply within the host. Though not very essential, but still could be used as drug targets. The emerging new fungal species is making the world to look for the development of new antifungal drugs which could lessen the people from symptoms.

Curcuma longa (Turmeric) was effectively used against many fungal infections since ages, but still clinically not advised owing to its poorer absorption. In this study, a total of ten compounds from the turmeric were screened for their potent binding affinities to the above said receptors, using the insilicodocking study, druglikeness properties, ADME/T test, PASS prediction along with P450 site of metabolism prediction.Form the experiment, micafungin and germacrene were found to be best docked ligands to the receptors, though micafungin was equally good in docking score to that of positive controls (Amphotericin B and caspofungin). Even the druglikeness properties, ADME/T test, PASS prediction along with P450 site of metabolism prediction all suggest germecrene to be more effective than micafungin. Moreover, germacrene was found to not toxic and nontumoric.
