mosquitoes transmit several human pathogens that cause millions of deaths worldwide, mainly in Latin America. The indiscriminate use of insecticides has resulted in the development of species resistance to some such compounds. Piperidine, a natural alkaloid isolated from , has been used as a hit compound due to its larvicidal activity against . In the present study, piperidine derivatives were studied through in silico methods: pharmacophoric evaluation (PharmaGist), pharmacophoric virtual screening (Pharmit), ADME/Tox prediction (Preadmet/Derek 10.0), docking calculations (AutoDock 4.2) and molecular dynamics (MD) simulation on GROMACS-5.1.4. MP-416 and MP-073 molecules exhibiting ΔG binding (MMPBSA -265.95 ± 1.32 kJ/mol and -124.412 ± 1.08 kJ/mol, respectively) and comparable to (ΔG binding = -216.21 ± 0.97) and pyriproxyfen (a well-known larvicidal, ΔG binding= -435.95 ± 2.06 kJ/mol). Considering future in vivo assays, we elaborated the theoretical synthetic route and made predictions of the synthetic accessibility (SA) (SwissADME), lipophilicity and water solubility (SwissADME) of the promising compounds identified in the present study. Our in silico results show that MP-416 and MP-073 molecules could be potent insecticides against the mosquitoes.
蚊子传播多种人类病原体,导致全世界数百万人死亡,主要集中在拉丁美洲。杀虫剂的滥用导致一些物种对这些化合物产生了抗性。从 中分离出的天然生物碱 已被用作命中化合物,因为它对 的幼虫具有杀幼虫活性。在本研究中,通过计算方法研究了 衍生物:药效团评估(PharmaGist)、药效团虚拟筛选(Pharmit)、ADME/Tox 预测(Preadmet/Derek 10.0)、对接计算(AutoDock 4.2)和分子动力学(MD)模拟在 GROMACS-5.1.4 上。MP-416 和 MP-073 分子表现出 ΔG 结合(MMPBSA-265.95 ± 1.32 kJ/mol 和 -124.412 ± 1.08 kJ/mol),与 (ΔG 结合 = -216.21 ± 0.97)和吡虫啉(一种著名的杀幼虫剂,ΔG 结合= -435.95 ± 2.06 kJ/mol)相当。考虑到未来的体内试验,我们详细阐述了理论合成路线,并对本研究中鉴定的有前途的化合物的合成可及性(SA)(SwissADME)、亲脂性和水溶性(SwissADME)进行了预测。我们的计算结果表明,MP-416 和 MP-073 分子可能是针对 蚊子的有效杀虫剂。
