Abstract:

The acetohydrazides <strong>A5 </strong>containing an isoxazole ring and<strong> B5</strong> containing an indazole ring were synthesized from the corresponding acetohydrazide derivatives with acetic anhydride in about 80% high yield. Also, two acetohydrazones <strong>B6</strong> and <strong>B7</strong> were driven from acetohydrazide <strong>B4</strong> by condensation reaction. Bioactivity testes showed that none of them were active against on bacteria except acetohydrazones <strong>B7</strong> showing moderate reactivit

Abstract:

One of the most important tasks of our indigenous pharmaceutical science is the necessity for new medicines because existing drugs are characterized by various side effects, resistance, high toxicity, and so on. New bioactive molecule synthesis utilizes substances of natural origin as well as chemically modified ones. Thus, the researcher’s attention is mainly focused on 3-,7-,8-substituted derivatives of the natural heterocyclic xanthine system, which possess a wide range of pharmacological action. Synthesis of a novel of (3-benzyl-8-propylxanthin-7-yl)acetohydrazides with antimicrobial and d

Abstract:

The title compound, C9H12N2O3, was synthesized by the reaction of ethyl 2-(4-methoxyphenoxy)acetate with hydrazine hydrate in ethanol. In the acetohydrazide group, the N—N bond is relatively short [1.413 (2) Å], suggesting some degree of electronic delocalization in the molecule. In the crystal, molecules are linked into sheets lying parallel to the ab plane by N—H...N and N—H...O hydrogen bonds.

Abstract:

<p class="Abstract">Two new pharmacologically active series of tetrazolopyridine-acetohydrazide conjugates [9 (a-n), 10 (a-n)] were synthesized by reacting a variety of suitably substituted benzaldehydes and isomeric 2-(5-(pyridin-3/4-yl)-2H-tetrazol-2-yl)acetohydrazides (7, 8). The synthesized compounds were analyzed through FTIR, <sup>1</sup>H NMR, <sup>13</sup>C NMR and elemental techniques. These acetohydrazides were screened for their in vivo antidiabetic activity and molecular docking studies. An excellent agreement was obtained as the best docked poses show

Abstract:

Inhibition of cyclooxygenases (COXs), by selective and nonselective inhibitors, is a favorable approach for pharmacologic intervention in a variety of disorders such as cancer. For this purpose, a new class of tetrazole-hydrazone hybrids (1-12) was designed. A facile and efficient procedure was applied for the preparation of compounds 1-12, which were tested for their inhibitory activities towards cyclooxygenases (COXs) by means of an in vitro colorimetric method. The most potent and selective COX-1 inhibitors were determined as 2-[(1-methyl-1H-tetrazol-5-yl)thio]-N'-(4-(piperidin-1-yl)benzyli

ABSTRACT: An efficient, cost effective and ecologically safe method for the design of series of novel 2-[(4-chloro-1,3-benzoxazol-2-yl)sulfanyl]-N'-[phenylmethylidene] acetohydrazides 5(a-j) have been synthesized by fusing 2-[(4-chloro-1,3-benzoxazol-2-yl)sulfanyl] acetohydrazide with substituted aromatic aldehyde. The prepared compounds were characterized via LC-MS, IR, 1H NMR, 13C NMR and C, H, N analysis technique. All the synthesized compounds were evaluated for biological potency, which includes antimicrobial, antifungal, antioxidant and anticancer activities. The compounds 5a, 5b, 5d, 5e

Abstract:

Novel (benzo[1,3]dioxol-5-yloxy)-N′-(4-substituted benzylidene)acetohydrazide derivatives were synthesized and their anticonvulsant activity evaluated by MES and scMET seizure models. Compound 2-(benzo[d][1,3]dioxol-5-yloxy)-N′-benzylideneacetohydrazide (4a) was found to be most potent in MES seizure test and showed no neurotoxicity at the highest administered dose. All the compounds showed high docking score with γ-aminobutyric acid receptor, GABAAR-β3 homopentamer (PDB ID: 4COF). Thus, the probable mechanism of action of benzo[1,3]dioxol-5-yloxy-N′-(4-substituted benzylidene)acetohydrazide d

Abstract:

The present study introduces the synthesis of two series of tetrazole derivatives. Firstly, monosubstituted S1 was prepared by the reaction of ethyl 4-aminobenzoate with an amount of sodium azide and triethyl orthoformate in hot glacial acetic acid. Then, ethyl 4-(1H-tetrazol-1-yl) benzoate S1 was treated with a solution of hydrazine hydrate to prepare acetohydrazide S2. After that, tetrazole derivatives S3-S4 were prepared via the reaction of acetohydrazide S2 with various aromatic aldehydes. Secondly, compound 1,5-disubstituted tetrazole S5 was prepared from the reaction of aryl isothiocyana
