Abstract:
:The metabolic pathway such as glyoxylate cycle (GC) enables Candida albicans, to survive under glucose deficient conditions prevalent in the hostile niche. Thus its key enzymes (Isocitrate lyase; ICL and malate synthase; MLS) represent attractive targets against C. albicans. We have previously reported the antifungal potential of a natural monoterpenoid perillyl alcohol (PA). The present study uncovers additional role of PA as a potent GC inhibitor. We explored that PA phenocopied ICL1 deletion mutant and were hypersensitive under low carbon utilizing conditions. The effect of PA on GC was substantiated by molecular docking analyses, which reveals the in-silico binding affinity of PA with ICL and MLS and explored that PA binds to the active sites of both proteins with better binding energy in comparison to their known inhibitors 3-nitropropionate and bromopyruvate respectively. Enzyme kinetics by Lineweaver-Burk plot unravels that PA inhibits ICL and MLS enzymes in competitive and non-competitive manner respectively. Moreover, semi-quantitative RT-PCR indicated that PA inhibits ICL1 and MLS1 mRNA expressions. Lastly, we demonstrated the antifungal efficacy of PA by enhanced survival of Caenorhabditis elegans model and less hemolytic activity (10.6%) on human blood cells. Further studies are warranted for PA to be considered as viable drug candidate.
