Abstract

Dermatophytic infection is a psychological burden due to its inefficacy in prolonged effectiveness during its course of treatment. The present study reports a novel antidermatophytic property from actinomycetes of wetlands soil. Total of 37 Streptomyces isolates were screened for antidermatophytic activity against Trichophyton mentagrophytes. The best isolate with 100% novel activity, was characterized and designated as Streptomyces albidoflavus STV1572a. Antidermatophytic compounds extracted from the mentioned strain were partially purified by chromatographic techniques. Further, it was characterized using UV-Vis spectroscopy, FTIR spectroscopy, and GC-MS analysis. Compound identified were, Phenol 2, 4-bis (1, 1-dimethylethyl), 9-octadecene (E), E-14- Hexadecenal, e-15- Heptadecenal, 1- Heneicosanol, Hypophosphonousdichloride bis (1, 1-dimethylethyl) and Heptadecyl trifluoroacetate. To sum up, this study illustrates an antidermatophytic lead compounds that pave its way for further purification and characterization of these compounds for their optimum utilization for antimycotic purposes.

摘要

皮肤癣菌感染是一种心理负担,因为其在治疗过程中疗效持续时间不长。本研究报告了湿地土壤放线菌的一种新型抗皮肤癣菌特性。总共筛选了37株链霉菌分离株对须癣毛癣菌的抗皮肤癣菌活性。具有100%新活性的最佳分离株被鉴定并命名为白黄链霉菌STV1572a。从上述菌株中提取的抗皮肤癣菌化合物通过色谱技术进行了部分纯化。此外,还使用紫外可见光谱、傅里叶变换红外光谱和气相色谱-质谱分析对其进行了表征。鉴定出的化合物有2,4-双(1,1-二甲基乙基)苯酚、9-十八碳烯(E)、E-14-十六碳烯醛、e-15-十七碳烯醛、1-二十一烷醇、次磷酸二氯双(1,1-二甲基乙基)和十七烷基三氟乙酸酯。总之,本研究阐明了一种抗皮肤癣菌先导化合物,为进一步纯化和表征这些化合物以将其最佳用于抗真菌目的铺平了道路。
