  Design and synthesis of novel triazole antifungal derivatives by structure-based bioisosterism

  摘要：

  The incidence of life-threatening fungal infections is increasing dramatically. In an attempt to develop novel antifungal agents, our previously synthesized phenoxyalkylpiperazine triazole derivatives were used as lead structures for further optimization. By means of structure-based bioisosterism, triazolone was used as a new bioisostere of oxygen atom. This type of bioisosteric replacement can improve the water solubility without loss of hydrogen-bonding interaction with the target enzyme. A series of triazolone-containing triazoles were rationally designed and synthesized. As compared with fluconazole, several compounds showed higher antifungal activity with broader spectrum, suggesting their potential for further evaluations. (C) 2011 Elsevier Masson SAS.

  Using dehydroabietic acid as the lead compound for structural modification, 25 dehydroabietic acid derivatives were synthesized. Among them, compound D1 not only showed the strongest relaxation effect on the aortic vascular ring in vitro (Emax = 99.5 ± 2.1%, EC50 = 3.03 ± 0.96 µM), but also significantly reduced systolic and diastolic blood pressure in rats at a dose of 2.0 mg/kg in vivo. Next, the

  以脱氢松香酸为先导化合物进行结构修饰，合成了25种脱氢松香酸衍生物。其中，化合物D1不仅在体外对主动脉血管环表现出最强的舒张作用（Emax=99.5±2.1%，EC 50 =3.03±0.96μM），而且在一定剂量下能显着降低大鼠的收缩压和舒张压。体内浓度为 2.0 mg/kg。接下来，通过HUVECs进一步研究最佳活性D1的血管保护作用及其分子机制。结果表明， D1以浓度依赖性方式诱导大鼠胸主动脉内皮依赖性舒张。使用 NG -硝基-l-精氨酸甲酯 ( l -NAME)、1 H -[1,2,4]-恶二唑并-[4,3-a]-喹喔啉-1-酮 (ODQ) 去除内皮或主动脉环预处理）和四乙铵（TEA）显着抑制D1诱导的松弛。此外，渥曼青霉素、KT5823、曲西立宾、地尔硫卓、BaCl 2 、4-氨基吡啶、吲哚美辛、普萘洛尔和阿托品可减弱D1诱导的血管舒张作用。 D1增加了 HUVEC 中 eNOS

  Based on the structure of the active site of cytochrome P450 14 alpha-demethylase (CYP51) and the conclusions of the structure-activity relationships of azole antifungals, a series of 1-(2-(2,4-difluorophenyl)-2-hydroxy-3-(1H-1,2,4-triazol-1-yl)propyl)-1H-1,2,4-triazol-5(4H)-one of fluconazole analogs was synthesized. All compounds were characterized by IR, HRMS, (HNMR)-H-1 and C-13 NMR spectroscopic analysis. Results of preliminary antifungal in vitro test using eight human pathogenic species showed that some compounds displayed comparable or even better antifungal activities than reference drug fluconazole and that compound 3i exhibited significant activity against Candida albicans being worthy of further optimization.
