To screen and identify ideal leading compounds from a drug library (ZINC15 database) with potential inhibition effect against c-Myc to contribute to medication design and development.A series of computer-aided virtual screening techniques were performed to identify potential inhibitors of c-Myc. LibDock from the software Discovery Studio was used to do a structure-based screening after ADME (absorption, distribution, metabolism, excretion) and toxicity prediction. Molecular docking was utilized to show the binding affinity and potential mechanism between ligands and c-Myc. Stability of the ligand-receptor complex was analyzed by molecular dynamic simulation at the end of the research.Compounds with more interactive energy which are confirmed to be the potential inhibitors for c-Myc were identified from the ZINC15 databases. Additionally, those compounds are also anticipated with fewer ames mutagenicity, rodent carcinogenicity, nondevelopmental toxic potential, and tolerant with cytochrome p450 2D6(CYP2D6). Dynamic simulation analysis also revealed that the very compounds had more favorable potential energy compared with 10058-F4(ZINC12406714). Furthermore, we prove that those compounds are stable and can exist in natural conditions.This study demonstrates that the compounds are potential therapeutic inhibitors for c-Myc. These compounds are safe and stable for drug candidates and may play a critical role in c-Myc inhibitor development.
从药物库(ZINC15 数据库)中筛选和鉴定具有潜在 c-Myc 抑制作用的理想先导化合物,为药物设计和开发做出贡献。采用一系列计算机辅助虚拟筛选技术,从 ZINC15 数据库中筛选具有潜在 c-Myc 抑制作用的先导化合物。在进行吸收、分布、代谢和排泄(ADME)以及毒性预测后,利用 Discovery Studio 软件中的 LibDock 进行基于结构的筛选。利用分子对接展示配体与 c-Myc 的结合亲和力和潜在作用机制。研究结束时,通过分子动力学模拟分析配体-受体复合物的稳定性。从 ZINC15 数据库中鉴定出与 c-Myc 具有更多相互作用能的化合物,这些化合物被确认为潜在的 c-Myc 抑制剂。此外,这些化合物还预计具有较少的 Ames 致突变性、啮齿动物致癌性、非发育毒性潜力,并且对细胞色素 P450 2D6(CYP2D6)具有耐受性。动态模拟分析还表明,与 10058-F4(ZINC12406714)相比,这些化合物具有更有利的潜在能量。此外,我们证明这些化合物是稳定的,可以在自然条件下存在。本研究表明,这些化合物是 c-Myc 的潜在治疗抑制剂。这些化合物作为候选药物是安全且稳定的,可能在 c-Myc 抑制剂的开发中发挥关键作用。
