Dihydrofolate reductase (DHFR) has gained significant attention in drug development, primarily due to marked distinctions in its active site among different species. DHFR plays a crucial role in both DNA and amino acid metabolism by facilitating the transfer of monocarbon residues through tetrahydrofolate, which is vital for nucleotide and amino acid synthesis. This considers its potential as a promising target for therapeutic interventions. In this study, our focus was on conducting a virtual screening of phytoconstituents from the IMPPAT2.0 database to identify potential inhibitors of DHFR. The initial criterion involved assessing the binding energy of molecules against DHFR and we screened top 20 compounds ranging energy -13.5 to -11.4 (kcal/Mol) while Pemetrexed disodium bound with less energy -10.2 (kcal/Mol), followed by an analysis of their interactions to identify more effective hits. We prioritized IMPHY007679 (), which displayed a high binding affinity and crucial interaction with DHFR. We also evaluated the drug-like properties and biological activity of IMPHY007679. Furthermore, MD simulation was done, RMSD, RMSF, Rg, SASA, PCA and FEL explore the time-evolution impact of IMPHY007679 comparing it with a reference drug, Pemetrexed disodium. Collectively, our findings suggest that IMPHY007679 recommend further investigation in both and settings for its potential in developing anticancer and antibacterial therapies. This compound holds promise as a valuable candidate for advancing drug research and treatment strategies.
二氢叶酸还原酶(DHFR)在药物研发中备受关注,主要是因为不同物种间其活性位点存在显著差异。DHFR通过四氢叶酸促进一碳残基的转移,在DNA和氨基酸代谢中发挥关键作用,而这对核苷酸和氨基酸合成至关重要。鉴于此,它具有作为治疗干预潜在靶点的可能性。在本研究中,我们聚焦于对IMPPAT2.0数据库中的植物成分进行虚拟筛选,以鉴定DHFR的潜在抑制剂。初始标准是评估分子与DHFR的结合能,我们筛选了结合能在-13.5至-11.4(千卡/摩尔)范围内的前20种化合物,而培美曲塞二钠的结合能较低,为-10.2(千卡/摩尔),随后分析它们的相互作用以确定更有效的命中物。我们将IMPHY007679()列为优先对象,它与DHFR表现出高结合亲和力和关键相互作用。我们还评估了IMPHY007679的类药性质和生物活性。此外,进行了分子动力学模拟,通过均方根偏差(RMSD)、均方根波动(RMSF)、回旋半径(Rg)、溶剂可及表面积(SASA)、主成分分析(PCA)和自由能景观(FEL)来探究IMPHY007679与参考药物培美曲塞二钠相比的时间演化影响。总体而言,我们的数据表明,IMPHY007679因其在开发抗癌和抗菌疗法方面的潜力,在[具体内容缺失]和[具体内容缺失]环境中值得进一步研究。该化合物有望成为推进药物研究和治疗策略的有价值候选物。
