Isoquinoline Promoted Synthesis of alkyl 2-(1-alkyl-5-oxo-3-phenyl-2-thioxotetrahydro-4H-imidazol-4-yliden) acetate derivatives
Derivatives of thiazolidinone ring systems are known to act as anti-HIV infections , analgesic, anti-bacterial, anti-convulsant, anti parasitic, potential anti-inflammatory and herbicidal agents. Due biological activities of thiazolidinones ring, several methods for their synthesis have been illustrated in literature. Imidazolidine-2-thiones were synthesized by the oxidative cyclization of 1-be...

متن کاملStudies on the Alkylation of Quinolin-2(1h)-one Derivatives
Alkylation of quinolin-2(1H)-one (1) and its C(6) and C(7) substituted dervatives (OMe, OBn, and Cl) with 2-bromoacetophenone or chloroacetone under basic condition (K2CO3 in DMF) gave a mixture of N1and O2alkylated products with the former one as a major product. However, alkylation of 8-methoxy-, 8-benzyloxy-, and 8-chloroquinolin-2(1H)-ones under the same reaction conditions gave exclusively...
متن کاملIn vitro and in vivo activities of 1-hydroxy-2-alkyl-4(1H)quinolone derivatives against Toxoplasma gondii.
1-Hydroxy-2-dodecyl-4(1H)quinolone (HDQ) was recently identified as a Toxoplasma gondii inhibitor. We describe here two novel 1-hydroxyquinolones, which displayed 50% inhibitory concentrations 10- and 5-fold lower than that of HDQ. In a mouse model of acute toxoplasmosis, these two compounds and HDQ reduced the percentages of infected peritoneal cells and decreased the parasite loads in lungs a...
متن کاملG-QSAR of Novel 2-{[2-(1H-imidazol-1-yl)ethyl]sulfanyl}-1H- benzimidazole Derivatives
In the present work, we have applied group quantitative structure–activity relationships (G-QSAR) for exploring the relationship between the structures of a new emerging family of 2-{[2-(1Himidazol-1-yl)ethyl]sulfanyl}-1H-benzimidazole derivatives and their antiprotozoal activities. We have developed descriptive models, in order to aid in further optimization and development of newer antiprotoz...
