Antitumor, Analgesic, and Anti-inflammatory Activities of Synthesized Pyrazolines
Nitrogen heterocyclic compounds such as pyrazolines have been found to possess a broad spectrum of biological activities such as anticancer, antitubercular, anti-inflammatory, analgesic, and antidepressant activities. Pyrazoline derivatives IV, V (a-e) have been synthesized from the intermediate chalcones III (a-h) by cyclizing with phenyl hydrazine and hydrazine hydrate. The structures of thes...
متن کاملSynthesis, cytotoxicity and carbonic anhydrase inhibitory activities of new pyrazolines.
A series of polymethoxylated-pyrazoline benzene sulfonamides were synthesized, investigated for their cytotoxic activities on tumor and non-tumor cell lines and inhibitory effects on carbonic anhydrase isoenzymes (hCA I and hCA II). Although tumor selectivity (TS) of the compounds were less than the reference compounds 5-Fluorouracil and Melphalan, trimethoxy derivatives 4, 5, and 6 were more s...
متن کاملTBD-organocatalysed synthesis of pyrazolines.
It was found that TBD, a cheap and commercially available guanidine, easily catalysed the synthesis of biologically important 3,5-diarylpyrazolines from chalcones and acylhydrazines via a selective secondary amine alkylation.
متن کاملDivergent syntheses of 2-aminonicotinonitriles and pyrazolines by copper-catalyzed cyclization of oxime ester.
Copper-catalyzed cyclization of an oxime ester toward divergent heterocycle synthesis is reported. Oxime ester serves as an enamine precursor to cyclize with malononitrile and aldehydes for access to 2-aminonicotinonitriles in a one-pot reaction, while cyclizing with N-sulfonylimines leads to synthesis of pyrazolines.
متن کاملFacile synthesis of spirooxindole-pyrazolines and spirobenzofuranone-pyrazolines and their fungicidal activity.
Novel spirooxindole-pyrazolines and spirobenzofuranone-pyrazolines have been synthesized in good to excellent yields via the annulation reactions of the corresponding 3-alkylideneoxindoles and 3-alkylidenebenzofuranones with Huisgen zwitterions. The preliminary bioassay demonstrated that some of the spiropyrazolines possess good in vitro fungicidal activity against several crop fungi at a conce...
