Therapeutic potential of biosurfactant (BS) has been improved in recent years. Our present study deals with production of BS from Planococcus maritimus SAMP MCC 3013 in a mineral salt medium (MSM) supplemented with glucose (1.5% w/v). Further, BS has been purified and partially characterized as glycolipid type through our previous publication. Current research article aimed to evaluate biological potential of BS against Mycobacterium tuberculosis, Plasmodium falciparum and cancerous cell lines. Planococcus derived glycolipid BS was found to be a promising inhibitor of M. tuberculosis (MTB) H37Ra at IC 64.11 ± 1.64 μg/mL and MIC at 160.8 ± 1.64 μg/mL. BS also showed growth inhibition of P. falciparum at EC 34.56 ± 0.26 µM. Additionally, BS also displayed the cytotoxicity against HeLa (IC 41.41 ± 4.21 μg/mL), MCF-7 (IC 42.79 ± 6.07 μg/mL) and HCT (IC 31.233 ± 5.08 μg/mL) cell lines. Molecular docking analysis was carried for the most popular glycolipid type BS namely Rhamnolipid (RHL) aiming to interpret the possible binding interaction for anti-tubercular and anti-cancer activity. This analysis revealed the involvement of RHL binding with enoyl reductase (InhA) of M. tuberculosis. Docking studies of RHL with tubulin directed several hydrophobic and Vander Waal interactions to exhibit anti-cancer potential. The present study will be helpful for further development of marine bioactive molecules for therapeutic applications. Their anti-tubercular, anti-plasmodial and cytotoxic activities make BS molecules as a noteworthy candidate to combat several diseases. To the best of our knowledge, this is the first report on projecting the pharmacological potential of Planococcus derived BS.
生物表面活性剂(BS)的治疗潜力近年来得到了提高。我们目前的研究涉及在补充葡萄糖(1.5%w/v)的无机盐培养基(MSM)中从 Planococcus maritimus SAMP MCC 3013 生产 BS。此外,BS 已通过我们之前的出版物被纯化并部分鉴定为糖脂类。当前的研究文章旨在评估 BS 对结核分枝杆菌、疟原虫和癌细胞系的生物学潜力。从 Planococcus 衍生的糖脂 BS 被发现是结核分枝杆菌(MTB)H37Ra 的有前途的抑制剂,IC 64.11±1.64μg/mL,MIC 为 160.8±1.64μg/mL。BS 还显示出对疟原虫生长的抑制作用,EC 34.56±0.26μM。此外,BS 还对 HeLa(IC 41.41±4.21μg/mL)、MCF-7(IC 42.79±6.07μg/mL)和 HCT(IC 31.233±5.08μg/mL)细胞系显示细胞毒性。进行了针对最流行的糖脂 BS 即鼠李糖脂(RHL)的分子对接分析,旨在解释其抗结核和抗癌活性的可能结合相互作用。该分析表明 RHL 与结核分枝杆菌的烯酰还原酶(InhA)结合。RHL 与微管蛋白的对接研究指导了几种疏水和范德华相互作用,以表现出抗癌潜力。本研究将有助于进一步开发用于治疗应用的海洋生物活性分子。它们的抗结核、抗疟原虫和细胞毒性活性使 BS 分子成为对抗多种疾病的有价值候选物。据我们所知,这是首次报道预测源自 Planococcus 的 BS 的药理学潜力。
