摘要

热带和亚热带地区受到疟疾的挑战;由恶性疟原虫引起的一种危及生命的疾病。抗疟药物耐药性的增加,特别是耐药恶性疟原虫菌株的增加,导致迫切需要新的抗疟药物。本研究的重点是使用计算技术来调查和分析在金盏花中发现的植物化学物质,金盏花是一种在非洲以治疗疟疾而闻名的植物,作为恶性疟原虫转酮醇酶的潜在抑制剂和假定的抗疟疾剂。计算技术,包括分子对接和分子动力学模拟,用于评估鉴定的植物化学物质与目标蛋白的结合亲和力、稳定性和相互作用。结果表明,Khivorin (AKT-6)、7-去乙酰基Khivorin (AKT-18)和1-去乙酰基Khivorin (AKT-22)这三种植物化学物质具有良好的药代动力学特性、药物相似性和与恶性疟原虫转酮醇酶的强结合亲和力。分子动力学模拟证实了蛋白质-配体复合物的稳定性,进一步支持了这些化合物作为抑制剂的潜力。所鉴定的植物化学物质在与转酮醇酶形成复合物时表现出显著的结合潜力和稳定性,具有最佳的药代动力学,表明它们有可能成为未来药物发现工作的先导化合物。图形化的简介:

Computational study of phytochemicals from Khaya grandifoliola (WELW) as potential inhibitors of the Plasmodium falciparum transketolase and putative antimalarial agents.

The tropical and subtropical region has been challenged with Malaria; a life-threatening disease caused by Plasmodium falciparum. The rise of anti-malarial drug resistance, especially drug resistant Plasmodium falciparum strains has led to the urgent need for novel antimalarial drugs. This study focuses on using computational techniques to investigate and profile phytochemicals found in K. grandifoliola, a plant known for its medicinal use in Africa for treating malaria in particular, as potential inhibitors of the Plasmodium falciparum transketolase enzyme and putative antimalarial agents. Computational techniques, including molecular docking and molecular dynamics simulations, were employed to assess the binding affinity, stability, and interactions of the identified phytochemicals with the target protein. The findings revealed that three phytochemicals, Khivorin (AKT-6), 7-deacetylkhivorin (AKT-18), and 1-deacetylkhivorin (AKT-22), exhibited favorable pharmacokinetic properties, drug-likeness, and strong binding affinity for the P. falciparum transketolase. Molecular dynamics simulations confirmed the stability of the protein-ligand complexes, further supporting the potential of these compounds as inhibitors. The identified phytochemicals that demonstrated significant binding potential and stability upon forming complex with transketolase, having optimum pharmacokinetics, suggests their potential as lead compounds for future drug discovery efforts.
