Abstract

Contemplating the exemplary benefits of pectin on human health, we precisely characterized and evaluated the antibacterial and anticancer activities from purified Mulberry Fruit Pectins (MFP). Here, we tested BR-2 and S-13 varieties of mulberry fruit pectins against six bacterial strains and two human cancer cell lines (HT-29 and Hep G-2), using MIC and an in vitro cell-based assay respectively. The BR-2 mulberry fruit pectin performs superior to S-13 by inhibiting strong bacterial growth (MIC = 500-1000 μg/mL) against tested bacterial strains and cytotoxic activities at the lowest concentration (10 µg/ml) against the Hep G-2 cell line. However, both tested drugs failed to exhibit cytotoxicity on the human colon cancer cell line (HT-29). Based on molecular interaction through docking, pectin binds effectively with the receptors (1e3g, 3t0c, 5czz, 6j7l, 6v40, 5ibs, 5zsy, and 6ggb) and proven to be a promising antimicrobial and anti-cancer agents. The pursuit of unexploited drugs from mulberry fruit pectin will potentially combat against bacterial and cancer diseases. Finally, future perspectives of MFP for the treatment of many chronic diseases will help immensely due to their therapeutic properties.

摘要

考虑到果胶对人类健康的典范益处,我们精确地描述和评估了从纯化的桑椹果胶(MFP)中获得的抗菌和抗癌活性。在这里,我们使用 MIC 和体外基于细胞的测定法分别测试了 BR-2 和 S-13 品种的桑椹果果胶对六种细菌菌株和两种人类癌细胞系(HT-29 和 Hep G-2)的作用。BR-2 桑椹果果胶的性能优于 S-13,因为它可以抑制测试的细菌菌株的强烈细菌生长(MIC=500-1000μg/mL),并且在最低浓度(10μg/ml)下对 Hep G-2 细胞系具有细胞毒性活性。然而,两种测试药物均未能对人结肠癌细胞系(HT-29)表现出细胞毒性。基于通过对接进行的分子相互作用,果胶可以有效地与受体(1e3g、3t0c、5czz、6j7l、6v40、5ibs、5zsy 和 6ggb)结合,并被证明是一种有前途的抗菌和抗癌药物。从桑椹果胶中寻找未开发的药物将有可能对抗细菌和癌症疾病。最后,由于 MFP 的治疗特性,MFP 治疗许多慢性疾病的未来前景将非常有帮助。
