  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.

  A simple and efficient procedure for the synthesis of 1,3,4‐thiadiazoles has been achieved using thiourea as organocatalyst. In this study, the steric and electronic effects using structurally different derivatives of urea and thiourea in different solvents were evaluated. The best yields and the rate of the reactions were obtained using 30 mol % of thiourea as catalyst in acetonitrile at room temperature

  An effective oxidative intramolecular cyclization (C–S bond formation) of thiosemicarbazones using 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) has been developed to afford a diverse array of 2-amino-substituted-1,3,4-thiadiazoles. The attractive features of this protocol are operational simplicity, obviates the need of expensive transition-metal catalysts and broad substrate scope.
