Three-dimensional (3D) multi-cellular aggregates (MCAs), as a model scaffold-free tissue construct, are useful for engineering cell-dense and matrix-poor tissues for repair and regeneration applications. To facilitate rapid MCA formation with high degrees of linker consistency and performance, we synthesized a class of dendrimer hydrazides with 8, 16 and 32 arms that can react with the aldehyde...

New platinum (II) complexes of cyclohexanecarboxylic acid hydrazide (chcah) were synthesized and characterized by elemental analysis, IR, and 1H NMR spectra. Their inhibitory effects on cell growth and macromolecular synthesis of Friend leukemia cells in culture as well as the in vivo antitumor activity towards L1210 leukemia in mice were compared with those of complexes containing differently ...

An unprecedented three-component oxysulfenylation reaction of alkenes with sulfonyl hydrazides and alcohols has been developed in the presence of 20 mol% iodine to give a range of structurally diverse β-alkoxy sulfides in good to excellent yields.

A variety of aromatic amines/hydrazides and aldehydes have been utilized for the construction of crystalline COFs at a faster rate and in high yield, irrespective of their reactivity and solubility using the Liquid-Assisted Grinding (LAG) method.

A series of eighteen 1,3,4-oxadiazole derivatives have been synthesized by treating aromatic acid hydrazides with carbon disulfide in ethanolic potassium hydroxide yielding potassium salts of 1,3,4-oxadiazoles. Upon neutralization with 1 N hydrochloric acid yielded crude crystals of 1,3,4-oxadiazoles, which were purified by recrystallization in boiling methanol. The synthesized 1,3,4-oxadiazole...

 The uses of non-steroidal anti-inflammatory drugs (NSAIDs) are limited by a variety of side effects. So research on preparing new analgesic agents is important. According to some reports about the analgesic activity of hydrazide and hydrazine derivatives a new series of these compounds were synthesized in order to obtain new analgesic compounds. The final compounds 10a-10e and 15a-15d were pre...

Background: Ofloxacin is a fluoroquinolone antibiotic very useful in the treatment of several bacterial infections. The Thiazolidinone ring system represents privileged structure drug discovery. multi-drug-resistant tuberculosis bacteria infects many people worldwide and disease kills 1.8 million annually, so combination ofloxacin-thiazolidinone ...
