The synthesis and characterization of some pyrazoline compounds of 1,3-diketones with hydrazine derivatives, namely, 1-(S-benzyldithiocarbazate)-3-methyl-5-phenyl-5-hydroxypyrazoline (1); 1-(2-thiophenecarboxylic)-3-meth ...
Montmorrilonite K10 catalyzed efficient synthesis of some 4'-nitrochalcones and their 1, 3, 5-triaryl-2-pyrazolines and in vitro antimicrobial evaluation
(Islamic Azad University Of Qaemshahr, 2016-07)
An expeditious synthesis of some 4´-nitrochalcones (3a-n) and their subsequent facile one-pot transformation to 1, 3,<br />5-triaryl-2-pyrazolines (4a-n) has been carried out using montmorrilonite K10 via microwave mediated ...
Hybrid Molecules Containing a 7-Chloro-4-aminoquinoline Nucleus and a Substituted 2-Pyrazoline with Antiproliferative and Antifungal Activity
(Molecular Diversity Preservation International, 2016-08)
Twenty-four new hybrid analogues (15-38) containing 7-chloro-4-aminoquinoline and 2-pyrazoline N-heterocyclic fragments were synthesized. Twelve of the new compounds were evaluated against 58 human cancer cell lines by the ...
New thiazolyl‐pyrazoline derivatives bearing nitrogen mustard as potential antimicrobial and antiprotozoal agents
(Wiley VCH Verlag, 2020-03-18)
A new series of N‐substituted pyrazoline derivatives 6a–g, 7a–g, 8a–g, and 9a–g was synthetized by reaction of hydrazine derivatives and chalcone–thiazole hybrids bearing nitrogen mustard 5a–g. The chalcones 5a–g were ...
