This study delves into the exploration of Clindamycin derivatives, specifically compounds and , to unveil their antitumor potential by employing a multidisciplinary approach. Screening a repertoire of 200 Clindamycin-associated targets pinpointed the Family A G-protein-coupled receptor as a prominent antitumor candidate. Subsequent analyses unearthed 16 pertinent antitumor proteins, with compound exhibiting robust affinity towards a specific protein via stable hydrogen bonding. Molecular dynamics simulations underscored the adrenergic receptor β as a pivotal target, primarily situated in the plasma membrane and endoplasmic reticulum. These revelations hint towards compound 's potential to bolster natural defense mechanisms against tumors by modulating immune responses within the tumor microenvironment, thus paving the way for novel avenues in antitumor drug development. Furthermore, employing the MTT assay, we evaluated the anti-HepG2 cell activity of compounds and , with 5-fluorouracil serving as the control drug. Results revealed that compound exhibited significant differences ( < 0.01) across all concentrations (2.5, 5, 10 μg/mL) compared to the control group, paralleled by the pronounced differences ( < 0.01) observed with 5-fluorouracil.
本研究深入探索克林霉素衍生物,特别是化合物 和 ,通过采用多学科方法揭示其抗肿瘤潜力。对200个与克林霉素相关的靶点进行筛选,确定A类G蛋白偶联受体为一个重要的抗肿瘤候选靶点。随后的分析发现了16种相关的抗肿瘤蛋白,化合物 通过稳定的氢键对一种特定蛋白表现出强大的亲和力。分子动力学模拟强调肾上腺素能受体β是一个关键靶点,主要位于质膜和内质网中。这些发现表明化合物 有可能通过调节肿瘤微环境中的免疫反应来增强机体对肿瘤的天然防御机制,从而为抗肿瘤药物开发开辟新途径。此外,我们采用MTT法评估了化合物 和 的抗HepG2细胞活性,以5-氟尿嘧啶作为对照药物。结果显示,与对照组相比,化合物 在所有浓度(2.5、5、10μg/mL)下均表现出显著差异( < 0.01),5-氟尿嘧啶也观察到了明显差异( < 0.01)。
