Metal-Free Synthesis of 1,3,4-Oxadiazoles from N′-(Arylmethyl)hydrazides or 1-(Arylmethyl)-2-(arylmethylene)hydrazines

An efficient and versatile metal-free synthesis of 1,3,4-oxadiazoles from N′-(arylmethyl)hydrazides or 1-(arylmethyl)-2-(arylmethylene)hydrazines through oxidative dehydrogenation is reported. A range of 2,5-disubstituted 1,3,4-oxadiazoles were prepared by treating N′-(arylmethyl)hydrazides with (diacetoxyiodo)benzene in acetonitrile or by treating 1-(arylmethyl)-2-(arylmethylene)hydrazines with [bis(trifluoroacetoxy)iodo]benzene in methyl tert-butyl ether. Aldehyde N-acylhydrazones and aldazines were initially generated in situ as intermediates.

2,5-Disubstituted-1,3,4-oxadiazoles: Thymidine phosphorylase inhibitors

A series of 2,5-disubstituted-1,3,4-oxadiazoles (1-16) were synthesized via microwave irradiation and screened against thymidine phosphorylase enzyme. Four members of the series have demonstrated thymidine phosphorylase inhibitory activities with IC50 values between 37 and 320 μM. Pyridinyl-containing 1,3,4-oxadiazoles exhibited an enhanced inhibitory potential, while phenyl analogs did not show substantial inhibitory potential. Compound 9, a dipyridinyl residue having an IC50 value of 37 ± 0.76 μM was found to be the most potent in the series superior to standard inhibitor 7-deazaxanthine (IC50 = 39.28 ± 0.76 μM).

Antimycobacterial and antimicrobial study of new 1,2,4-triazoles with benzothiazoles

In this study, we report the antimycobacterial and antimicrobial evaluation of newly synthesized 3-(3-pyridyl)-5-(4-methoxyphenyl)-4-(N-substituted-1,3- benzothiazol-2-amino)-4H-1,2,4-triazole 6a-j in good yields. All the synthesized compounds have been established by elemental analysis, IR, 1H NMR, 13C-NMR and Mass spectral data. In-vitro antimycobacterial activity was carried out against (Mycobacterium tuberculosis) H37Rv strain using Lowenstein-Jensen medium and antimicrobial activity against two Gram positive bacteria (Staphylococcus aureus, Streptococcus pyogenes), two Gram negative bacteria (Escherichia coli, Pseudomonas aeruginosa) and three fungal species (Candida albicans, Aspergillus niger, Aspergillus clavatus) using the broth microdilution method. Compounds 2e, 6a, 6g, 6h, and 6j exhibited promising antimicrobial activity whereas compound 6j showed very good antimycobacterial activity. The antimycobacterial and antimicrobial evaluation of newly synthesized 3-(3-pyridyl)-5-(4-methoxyphenyl)-4-(N-substituted-1,3-benzothiazol- 2-amino)-4H-1,2,4-triazoles is reported in detail. Compounds 2e, 6a, 6g, 6h, and 6j exhibited promising antimicrobial activity whereas compound 6j showed very good antimycobacterial activity. Copyright
