TL;DR: Two new series of Hantzsch 1,4-dihydropyridine derivatives containing substituted pyrazole moiety were synthesized by the reaction of 3-aryl-1H-pyrazole-4-carbaldehydes with 1,3-dicarbonylcompounds (ethylacetoacetate and methylaceto acetate) and ammonium acetate and were found to be potent antibacterial and antioxidant agents.

TL;DR: Two series of novel imidazole derivatives containing substituted pyrazole moiety (3a-d and 5a-j) were synthesized and compound 3c was found to be potent antimicrobial agent.

TL;DR: A series of novel 2,4-disubstituted thiazole derivatives containing substituted pyrazole moiety showed significant antibacterial activity against all tested microorganisms.

TL;DR: An efficient, microwave irradiated synthesis of novel chromeno[2,3-b]-pyrimidine derivatives was carried out and few of the compounds are found to be potential antimicrobials.

TL;DR: In this article, two series of imidazoles were prepared: i) reaction of thiosemicarbazones (I) with dimethylacetylenedicarboxylate (II) furnishes the imidiazoles (III) in good yields; ii) trisubstituted imidozoles (VI) are obtained by refluxing diketones (IV) with pyrazole carbaldehydes (V) and ammonium acetate via Debus reaction.
