  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.

  studied by electron ionization (EI) and electrospray ionization (ESI) as methods of ion generation. To explain the observed complex skeletal rearrangements, tandem mass spectrometry, accurate mass measurement and isotope labeling (compounds containing one 13C atom in oxadiazole ring) were used. Loss of CO, N2 and H atoms under EI conditions led to the formation of 9,10-dihydroacridine-type ions, loss of

The resulting 2-amino-1,3,4-oxadiazole and 2-amino-1,3,4-thiadiazole core skeleton are functionalized with various electrophiles such as alkyl halide, acid halides, and sulfornyl chloride in high yields.

  A series of novel 5-phenyl-substituted 1,3,4-thiadiazole-2-amines were designed, synthesized, and screened for their antitumor and antitubercular activities. The target compounds were synthesized starting from isocyanates and acid hydrazides by conventional and microwave-assisted protocols. The structures of the products were confirmed by H-1 NMR, C-13 NMR, high-resolution mass spectrometry, and IR spectroscopy and elemental analysis. Some of the synthesized compounds showed significant invitro antitumor activities against breast cancer and normal human cell lines. Among them, N-benzyl-5-(4-fluorophenyl)-, N-benzyl-5-(4-nitrophenyl)-, and 5-phenyl-N-(p-tolyl)-1,3,4-thiadiazole-2-amines demonstrated higher inhibitory activities against the MDA-MB-231 cell line than the cisplatin control (IC50 3.3 M). N-Benzyl-5-(4-methoxyphenyl)-, 5-phenyl-N-[4-(trifluoromethyl)phenyl]methyl-, N-benzyl-5-(4-fluorophenyl)-, and N-benzyl-5-(4-nitrophenyl)-1,3,4-thiadiazole-2-amines exhibited high inhibitory activities against the HEK293T cell line (IC50 52.63, 42.67, 34.71, and 33.74 M, respectively), which were higher compared to the cisplatin control. In antitubercular activity testing against mycobacterium smegmatis MC155, 5-phenyl-N-[4-(trifluoromethyl)-phenyl]methyl-1,3,4-thiadiazole-2-amine proved to be a more potent agent (MIC 26.46 g/mL) compared to the Isoniazid control (12 g/mL). Potential bioactivities of the synthesized compounds were computed using Molinspiration and Molsoft software tools.
