Synthesis, Biological Activities, and Quantitative Structure–Activity Relationship (QSAR) Study of Novel Camptothecin Analogues
mmol/L and 0.00942 mmol/L, respectively) compared with CPT (LC50 0.19719 mmol/L) against T. Cinnabarinus. Based on the observed bioactivities, preliminary structure–activityrelationship (SAR) correlations were also discussed. Furthermore, a three-dimensional quantitativestructure–activityrelationship (3D-QSAR) model using comparative molecular field analysis (CoMFA) was built. The model gave statistically
A series of novel 2,3-dihydro-4H-1-benzoselenin-4-one (thio)semicarbazone derivatives were designed and synthesized by using molecular hybridization approach. All the target compounds were characterized by HRMS and NMR and evaluated in vitro antifungal activity angainst five pathogenic strains. In comparison with precursor selenochroman-4-ones, the hybrid molecules in this study showed significant
通过分子杂交的方法,设计合成了一系列新颖的2,3-二氢-4 H -1-苯并硒啉-4-酮(硫代)半碳zone酮衍生物。所有目标化合物均通过HRMS和NMR进行了表征,并针对五种病原菌株评估了其体外抗真菌活性。与前体硒代苯并二氢吡喃-4-酮相比,本研究中的杂化分子显示出显着的抗真菌活性。值得注意的是,化合物B8对除烟曲霉以外的其他菌株均表现出显着的抗真菌活性(白色念珠菌为0.25μg/ mL,新隐球菌为2μg/ mL,玉米芽孢杆菌为8μg / mL)。氟康唑敏感菌株白色念珠菌(Candida albicans)的浓度为2μg/ mL )。此外,化合物B8,B9和C2还显示出对四种氟康唑耐药菌株的最有效活性。特别地,杂合分子B8对耐氟康唑的菌株的MIC值在0.5-2μg/ mL的范围内。因此,本研究中的分子杂交方法为抗真菌药物的开发提供了新思路。

(11) ų, Z = 2. In addition, DIZ and MIC assays were used to examine the in vitro antifungal activity of the title conjugates 5a⁻o against four fungal strains. Compound 5e, bearing a 4-ethoxyphenyl fragment, showed the best MIC value (0.304 µmol/mL) against both C. tropicalis and C. parapsilosis species, while compounds 5c (MIC = 0.311 µmol/mL), 5k, and 5l (MIC = 0.287 µmol/mL) exhibited the best anti-C
