  3-(Substituted phenyl)imidazolidine-2-thiones (SPITs) and related compounds were synthesized by cyclizing monoethanolamine hydrogen sulfate with arylisothiocyanates in the presence of sodium hydroxide. The activity for stimulating adenylate cyclase prepared from thoracic nerve cords of the American cockroach, Periplaneta americana L., was examined with these compounds. A SPIT with a 2,6-diethylphenyl

  通过在氢氧化钠存在下将单乙醇胺硫酸氢盐与芳基异硫氰酸酯环化，可以合成3-（取代的苯基）咪唑烷-2-硫酮（SPIT）和相关化合物。用这些化合物检查了刺激从美国蟑螂美洲大i的胸神经线制备的腺苷酸环化酶的活性。具有2,6-二乙基苯基基团的SPIT（48）是唯一的完全激动剂，其他SPIT衍生物是部分激动剂。更大的酶活化似乎是由短链烷基而不是SPITs芳香环的2,6-位上的卤素取代引起的。在2,6-二取代的SPIT中，从甲基到乙基的链长增加导致酶激活增加。同时，在2中，从乙基到异丙基的链长进一步增加 6-二取代的SPIT导致酶活化降低。能量最小的章鱼胺和48的叠加显示出结构和构象相似，这说明48的Vmax值更高。在有效SPIT的咪唑烷环的C4或C5烷基化后，酶的活化作用明显降低。因此，在SPIT的苯环和N-末端的2-位和6-位的一定程度的蓬松度和疏水性对于活化腺苷酸环化酶是有利的。

  In view of the emergence and frequency of multidrug-resistant and extensively drug-resistant tuberculosis and consequences of acquired resistance to clinically used drugs, we undertook the design and synthesis of novel prototypes that possess the advantage of the two pharmacophores of thiourea and 1,3,4-thiadiazole in a single molecular backbone. Three compounds from our series were distinguished from the others by their promising activity profiles against Mycobacterium tuberculosis strain H37Rv. Compounds 11 and 19 were the most active representatives with minimum inhibitory concentration (MIC) values of 10.96 and 11.48 µM, respectively. Compound 15 was shown to inhibit M. tuberculosis strain H37Rv with an MIC value of 17.81 µM. Cytotoxicity results in the Vero cell line showed that these three derivatives had selectivity indices between 1.8 and 8.7. In order to rationalize the biological results of our compounds, molecular docking studies with the enoyl acyl carrier protein reductase (InhA) of M. tuberculosis were performed and compounds 11, 15, and 19 were found to have good docking scores in the range of −7.12 to −7.83 kcal/mol.

  考虑到多药耐药和广泛耐药结核病的出现和频率，以及对临床使用药物获得性耐药的后果，我们进行了新型原型药物的设计和合成，这些药物在一个分子骨架上同时具有硫脲和1,3,4-噻二唑两种药效基团的优势。在我们的系列化合物中，有三种化合物因其对结核分枝杆菌H37Rv株的潜在活性特征而脱颖而出。化合物11和19是最具活性的代表，其最小抑制浓度（MIC）值分别为10.96和11.48微摩尔。化合物15显示对结核分枝杆菌H37Rv株的MIC值为17.81微摩尔。在Vero细胞系中的细胞毒性结果显示，这三种衍生物的选择性指数在1.8至8.7之间。为了合理化我们化合物的生物学结果，我们进行了分子对接研究，与结核分枝杆菌的烯酰载体蛋白还原酶（InhA）结合，发现化合物11、15和19的对接得分在-7.12至-7.83千卡/摩尔的范围内。
