Selected sets of tetrahydro-5,5′-bi(1,2,4-triazines) (1-3) appended with acetyl, benzoyl, and ester moieties at C-3 position and N-1 (p-substituted)phenyl ring have been prepared and characterized by spectral (IR, NMR, MS) data and X-ray diffraction for c

New hydrazonoyl chloride derivatives were prepared and characterized. Their VO(II) complexes were isolated after adjusting reaction medium to slightly basic by 0.5?g acetate. Neutral tridentate mode is a general coordination feature of ligands towards bin

In this study, we synthesized two series of novel 5-nitrofuran-2-carbohydrazides 21a-h and 22a-e in addition to a third series of thiophene-2-carbohydrazides 23a-g to develop potent antimicrobial and/or antitubercular agents. The newly synthesized compounds were evaluated in vitro for their antimicrobial and antimycobacterial activities. Most of the 5-nitrofuran-2-carbohydrazides 21a-h and 22a-e displayed variable activity against Aspergillus fumigates, Staphylococcus aureus, Streptococcus pneumonia, Bacillis subtilis, Salmonella typhimurium, Klebsiella pneumonia, Escherichia coli and Mycobacterium tuberculosis. The sulfonamide derivative 21f exhibited superior potency and broad-spectrum antimicrobial activity with minimum inhibitory concentration (MIC)=0.06-0.98 μg/mL and antimycobacterial activity with MIC=3.9 μg/mL. The 5-nitrofuran-2-carbohydrazides 21a, b, g, h and 22a-c exhibited significant antibacterial activity with MIC values in the range of 0.12-7.81 μg/mL. The significances of the 5-nitrofuran moiety and sulfonamide function were explored via the structure-activity relationship (SAR) study. In addition, docking studies revealed that the p-amino benzoic acid (PABA) and binding pockets of the dihydropteroate synthase (DHPS) were successfully occupied by compound 21f. Furthermore, two quantitative structure-activity relationship (QSAR) models were built to explore the structural requirements which controlled the activity.

The reaction of nitrile imines (II) with α-amino esters (III) proceeds with no detectable racemization and constitutes a convenient synthetic route to 4,5-dihydro-1,2,4-triazin-6-ones (IV).Permangamate oxidation of heterocycles (IV) affords the corresponding 1,2,4-triazin-6-ones (V).The reaction of (II) with β-amino esters gives the respective acyclic amidrazone adducts (VI).
