against CA I, II and IX, and weak inhibition against CA IV. Some of the derivatives displayed selectiveinhibition towards tumor-associated CA IX isoform, within the nanomolar range. These potent compounds were also screened for their selective toxicity to evaluate their in vitro anti-proliferative effects on Human Gingival Fibroblasts (HGFs) and breast adenocarcinoma cell line (MCF7).

为了开发新的潜在抗肿瘤剂,已使用尾部方法开发了两个系列的苯和苯并噻唑磺酰胺衍生物,作为有效的人碳酸酐酶 (hCA, EC 4.2.1.1) 抑制剂。合成的化合物(XS-1至XS-22) 对 hCA 的生理相关异构体、细胞溶质 CA I 和 II、膜结合 CA IV 和肿瘤相关 CA IX 的抑制作用进行了测定。发现这两个系列的化合物对 CA I、II 和 IX 表现出低至中等纳摩尔范围的抑制作用,对 CA IV 表现出弱抑制作用。一些衍生物在纳摩尔范围内对肿瘤相关的 CA IX 异构体表现出选择性抑制。还筛选了这些有效化合物的选择性毒性,以评估它们对人牙龈成纤维细胞 (HGF) 和乳腺癌细胞系 (MCF7) 的体外抗增殖作用。最后,进行了分子对接研究,以解释那些有助于区分选定的人碳酸酐酶同种型的结构要求。
Synthesis, antifungal activities and molecular docking studies of novel 2-(2,4-difluorophenyl)-2-hydroxy-3-(1H-1,2,4-triazol-1-yl)propyl dithiocarbamates
A series of 2-(2,4-difluorophenyl)-2-hydroxy-3-(1H-1,2,4-triazol-1-yl)propyl dithiocarbamates as new analogs of fluconazole were synthesized and their antifungal activities were evaluated. Among these compounds, 2a-f and 3a-q exhibited higher activities than fluconazole against nearly all fungi tested except Aspergillus fumigatus. Noticeably, the in vitro biological activities of 2b, 3a, 3c, 3h-k, and 3o-q against Candida species were much better than those of fluconazole and ketoconazole. Also, 2a-d, 3a-d, 3e-f, 3h-k, 3p and 3q showed higher activities against A. fumi than fluconazole. Computational docking experiments indicated that the inhibition of CYP51 involved a coordination bond with iron of the heme group, the hydrophilic H-bonding region, the hydrophobic region, and the narrow hydrophobic cleft.

Synthesis and Cytotoxicity Screening of Piperazine-1-carbodithioate Derivatives of 2-Substituted Quinazolin-4(3<i>H</i>)-ones
piperazine‐1‐carbodithioate derivatives of 2‐substituted quinazolin‐4(3H)‐ones were synthesized via a five‐steps procedure starting from 2‐amino‐5‐methylbenzoic acid. The cytotoxicity of the resulting compounds against A‐549 (human lung cancer), HCT‐8 (human colon cancer), HepG2 (human liver cancer), and K562 (human myelogenous leukaemia) cell lines was determined by the MTT assay. Preliminary screening results of
