Synthesis, Identification, and Evaluation of Antibacterial Activity of Some New 4,5-Dihydro-1H-Pyrazoles, Derivatives from Substituted Chalcones

In this work, a series of new 4,5-dihydro-1H-pyrazole derivatives (M21-M25) has been synthesized successfully via the reaction of different aldehydes with ketones to produce chalcones, followed by the reaction with hydrazine and phenyl hydrazine. The prepared compounds were identified using FT-IR spectroscopy, 1H NMR spectroscopy, and 13C NMR spectroscopy.

Synthesis and prediction of the biological activity of heterocyclic n-derivatives naphthoquinone

The most urgent task of organic and pharmaceutical chemistry today is the search for new biologically active compounds, which in future can be used as promising substances for the development of new low-toxic, high-performance medicinal products. To this end, heterocyclic N-derivatives of 1,4-dichloroanotoquinone were synthesized and their drug-like characteristics were determined.
