چکیده

A new series of antimycobacterial agents 2a–j, 3a–d, 6b–f,j, and 7b,f was designed, synthesized and evaluated for antimycobacterial activity against different mycobacterium species i.e. M. tuberculosis, M. avium, and M. intracellulare in an agar dilution method. Some of these compounds (2e, 3a–d) were highly potent with in vitro activity against M. tuberculosis H37Rv and clinical isolates (sensitive strains), equivalent to that of Isoniazid.

Synthesis, Characterization and Antibacterial Activity Studies of Some N-Acyl-N'-aryl Thiourea Derivatives

Some N¬-acyl-N'-aryl thiourea derivatives 4(a-f) have been prepared by the reaction of acyl halides ammonium thiocyanate and aryl amines. The structures of synthesized compounds have been characterized by IR, 1HNMR spectral studies. The synthesized compounds 5(a-f) have been screened for antibacterial activity. The effect of the structure of the investigated compounds on the antibacterial activ...

Three-Component and Click Strategy for Synthesis of β-Hydroxy 1,4-Disubstituted 1,2,3-Triazoles Derivatives Catalyzed by 1,4-Dihydroxyanthraquinone-copper(II) Complex onto Nano AlPO4

In this work, copper(II) heterogeneous nanocatalyst supported on modified AlPO4 (Cu(II)-DA@Nano AlPO4) was used for the synthesis of some biological active heterocyclic molecules, particularly for the efficient conversion of a wide range of non-activated terminal alkynes to β-hydroxy 1,4-disubstituted 1,2,3-triazolethrough a three-component “click” reaction at room temperature in water. The reg...

Synthesis and Antimycobacterial Activity of 2-(Phenylthio) benzoylarylhydrazone Derivatives

A series of new 2-(phenylthio) benzoylaryl hydrazones were synthesized by acid-catalyzed condensation of hydrazide 3 with corresponding aldehydes. The chemical structures of the compounds were elucidated by FT-IR, 1H-NMR and Mass spectra. All newly synthesized compounds were evaluated for their antimycobacterial activities against Mycobacterium tuberculosis H37Rv using the microplate alamar blu...

Synthesis and Antimycobacterial Activity of some Triazole Derivatives–New Route to Functionalized Triazolopyridazines

A series of cyclic analogues of bioactive thiosemicarbazide derivatives have been synthesized as potential antimycobacterial agents. The 4-amino-1,2,4-triazole-5-thione analogues (Ia-f) were prepared by heating a mixture of thiocarbohydrzide and appropriate carboxylic acids. Reaction of thiocarbohydrazide with γ-ketoesters in the presence of sodium methoxide furnished triazolopyridazine derivat...
