is one of the major causative agents of mucormycosis. The disease has a poor prognosis with a high mortality rate, and resistance towards current antifungal drugs poses additional concern. The disease treatment is complicated with antifungals; therefore, surgical approach is preferred in many cases. A comprehensive understanding of the pathogenicity-associated virulence factors of is essential to develop new antifungals against this fungus. Virulence factors in include cell wall proteins, spore germination proteins and enzymes that evade host immunity. The spore coat protein (CotH3) and high-affinity iron permease (FTR1) have been identified as promising therapeutic targets in screening is a preferred approach to identify hit molecules for further studies. In the present study, twelve bioactive molecules were docked within the active site of CotH3 and FTR1. Further, molecular dynamics simulation analysis of best-docked protein-ligand structures revealed the dynamics information of their stability in the biological system. Eugenol and isoeugenol exhibited significant binding scores with both the protein targets of and followed the Lipinski rule of drug-likeness. To corroborate the results, studies were conducted using bioactive compounds eugenol, isoeugenol, and myristicin against isolated from the soil sample. Eugenol, isoeugenol exhibited antifungal activity at 156 µg/mL whereas myristicin at 312 µg/mL. Hence, the study suggested that eugenol and isoeugenol could be explored further as potential antifungal molecules against
是毛霉病的主要病原体之一。该疾病预后较差,死亡率高,对当前抗真菌药物的耐药性引发了更多关注。抗真菌药物治疗该疾病较为复杂,因此在许多情况下首选手术方法。全面了解与致病性相关的毒力因子对于开发针对这种真菌的新型抗真菌药物至关重要。的毒力因子包括细胞壁蛋白、孢子萌发蛋白和逃避宿主免疫的酶。孢子 coat 蛋白(CotH3)和高亲和力铁通透酶(FTR1)已被确定为筛选中的有前景的治疗靶点,筛选是识别用于进一步研究的命中分子的首选方法。在本研究中,12 种生物活性分子被对接至 CotH3 和 FTR1 的活性位点内。此外,对最佳对接的蛋白质 - 配体结构进行分子动力学模拟分析揭示了它们在生物系统中稳定性的动力学信息。丁香酚和异丁香酚与的两个蛋白质靶点均表现出显著的结合分数,并符合类药的 Lipinski 规则。为了证实结果,使用生物活性化合物丁香酚、异丁香酚和肉豆蔻醚对从土壤样品中分离出的进行了研究。丁香酚、异丁香酚在 156 µg/mL 时表现出抗真菌活性,而肉豆蔻醚在 312 µg/mL 时表现出抗真菌活性。因此,该研究表明丁香酚和异丁香酚可作为针对的潜在抗真菌分子进一步探索
