  Synthesis and testing of 3-acetyl-2,5-disubstituted-2,3-dihydro-1,3,4-oxadiazole derivatives for antifungal activity against selected Candida Species

  摘要：

  A series of 21 1,3,4-oxadiazoline derivatives was synthesized by cyclization of N-acylhydrazones with acetic anhydride and evaluated for their in vitro antifungal activity against six Candida strains: Candida albicans (ATCC 90028 and LM V-42), C. krusei (ATCC 6258 and LM 12 C) and C. tropicalis (ATCC 13803 and LM 14). The Candida strains were found to be sensitive to some of the compounds, which inhibited the growth by 50-90%, with minimum inhibitory concentration (MIC) in the range of 64-512 mu g mL(-1). The compounds' structures were fully confirmed and characterized by Fourier transform infrared spectroscopy (FTIR), H-1 and C-13 nuclear magnetic resonance (NMR) and mass spectrometry (MS).

  Background: Vasoconstriction is a major pathological feature of cardiovascular diseases involving endothelium dependent and independent mechanisms. Oxadiazole moiety appeared to be effective in various pathologies. Objective: The aim of the study was to synthesize and evaluate the mechanism of vasorelaxation exhibited by synthesized oxadiazole derivatives. Method: The 2,5-disubstituted-1,3,4-oxadiazole derivatives were synthesized by an efficient and simple method. The derivatives were investigated for their ex-vivo vasorelaxant action on intact/denuded endothelium rat aortic rings precontracted with norepinephrine/ phenylephrine/KCl. Results: The contractions induced in the aortic rings by the addition of cumulative concentrations of norepinephrine, phenylephrine, KCl and calcium were significantly antagonized by a derivative, OXD-Z2. In another experiment, verapamil pretreatment inhibited phenylephrine and Ca2+-induced aortic contractions and OXD-Z2 did not alter verapamilinduced inhibition. This indicated the role of L-type Ca2+-channels in the OXD-Z2-induced vasorelaxation via inhibition of calcium influx. Further, atropine (muscarinic receptor antagonist), L-NAME (NO synthase inhibitor) and methylene blue (non-selective cGMP inhibitor) inhibited OXD-Z2-induced relaxation in other sets of experiments. These results indicate that OXD-Z2 also mediates vasorelaxation through NO release by muscarinic receptor activation. In addition, the molecular docking studies showed that OXD-Z2 interacts with L-type Ca2+-channel, muscarinic (M2) receptor and eNOS. Conclusion: Thus, it is deduced from the above findings that the vasorelaxant activity of OXD-Z2 involves muscarinic receptor-mediated nitric oxide release in addition to direct inhibition of L-type Ca2+-channels.

  背景：血管收缩是心血管疾病的一个主要病理特征，涉及内皮依赖和独立机制。草酰二唑似乎对各种病症有效。 目的：本研究旨在合成和评估草酰二唑的血管舒张机制：本研究的目的是合成并评估合成的噁二唑衍生物的血管舒张机制。 方法：2,5-二取代的噁二唑衍生物：采用高效简单的方法合成了 2,5-二取代-1,3,4-噁二唑衍生物。研究了这些衍生物对去甲肾上腺素/苯肾上腺素/氯化钾预收缩的完整/脱落内皮大鼠主动脉环的体内外血管舒张作用。 结果：在主动脉环上加入累积浓度的去甲肾上腺素、苯肾上腺素、氯化钾和钙后，OXD-Z2 衍生物可显著拮抗其引起的收缩。在另一项实验中，维拉帕米预处理抑制了去甲肾上腺素和 Ca2+诱导的主动脉收缩，而 OXD-Z2 并未改变维拉帕米诱导的抑制作用。这表明 L 型 Ca2+ 通道在 OXD-Z2 通过抑制钙离子流入诱导的血管舒张中发挥作用。此外，在其他实验中，阿托品（毒蕈碱受体拮抗剂）、L-NAME（NO 合酶抑制剂）和亚甲蓝（非选择性 cGMP 抑制剂）也抑制了 OXD-Z2- 诱导的松弛作用。这些结果表明，OXD-Z2 还能通过激活毒蕈碱受体释放 NO 来介导血管舒张。此外，分子对接研究表明，OXD-Z2 与 L 型 Ca2+ 通道、毒蕈碱（M2）受体和 eNOS 相互作用。 结论：因此，根据上述研究结果推断，OXD-Z2 的血管舒张活性除了直接抑制 L 型 Ca2+ 通道外，还涉及毒蕈碱受体介导的一氧化氮释放。
