  1,3,4-Thiadiazole Derivatives. Synthesis, Structure Elucidation, and Structure−Antituberculosis Activity Relationship Investigation

  摘要：

  A series of 2,5-disubstituted-1,3,4-thiadiazoles were synthesized, the compounds structures were elucidated and screened for the antituberculosis activity against Mycobacterium tuberculosis H37Rv using the BACTEC 460 radiometric system. Among the tested compounds, 2-phenylamino-5-(4-fluorophenyl)-1,3,4-thiadiazole 22 showed the highest inhibitory activity. The relationships between the structures of compounds and their antituberculosis activity were investigated by the Electronic-Topological Method (ETM) and feed forward neural networks (FFNNs) trained with the back-propagation algorithm. As a result of the approach, a system of pharmacophores and anti-pharmacophores has been found that effectively separates compounds of the examination set into groups of active and inactive compounds. The system can be applied to the screening and design of new active compounds possessing skeletons similar to those used in the present study.

  interaction of amidrazones and isocyanate esters in dimethylformamide produces good yields of 4-substituted -1-imidoylsemicarbazides. They are unaffected by acids, but are cyclised to 3-alkyl (or aryl)-1,2,4-triazol-3-ones or their 4-substituted analogues in alkaline media. Analogous linear adducts arising in good yields from amidrazones and ethoxycarbonyl isothiocyanates are cyclised to 3-substituted

  4-thiadiazoles (I; X = Cl) were treated with several nucleophilic agents in different solvents. Displacement of chlorine by piperidine was chosen for a kinetic study in ethanol and in benzene, in the temperature range 30–60°. Reactions were first order with respect to both reagents in ethanol, while a third-order term appeared in benzene. Substituents on the Ph ring affected the rate of nucleophilic exchange

  一些2-芳基-5-氯-1,3,4-噻二唑（Ⅰ； X = Cl）在不同溶剂中用几种亲核试剂处理。为了在30-60°C的温度范围内在乙醇和苯中进行动力学研究，选择了哌啶取代氯。对于两种试剂，在乙醇中的反应是一阶的，而在苯中则是三阶的。在乙醇中，Ph环上的取代基在50°下的Hammett相对值为1·47，从而影响亲核交换的速率。动力学结果与该类和其他类噻二唑的理论预期值和实验数据进行了比较。
