Hepatoprotective pyrrole derivatives of Lycium chinense fruits.
As a part of our search for hepatoprotective compounds from Lycium chinense fruits, three new pyrrole derivatives (1-3) were isolated. These compounds and a related synthetic methylated compound (4) were evaluated for their biological activity and structure-activity relationship, and compounds 1 and 2 showed hepatoprotective effects comparable to silybin at the concentration of 0.1 microM (64.4...
متن کاملSynthesis of New Derivatives of Pyrrole Tuberculostatics Providing Structural Diversity
Nine pyrrole-containing compounds were designed introducing reasonable structural novelties within the framework of the architecture of confirmed tuberculostatics. The new products were synthesized via adopted Paal-Knorr cyclization by condensation of three 1,4-dicarbonyl compounds with a set of substituted anilines, acting as primary amines. Preliminary in vitro tests have already registered e...
متن کاملSynthesis of certain pyrrole derivatives as antimicrobial agents.
In an effort to establish new pyrroles and pyrrolo[2,3-d] pyrimidines with improved antimicrobial activity we report here the synthesis and in vitro microbiological evaluation of a series of pyrrole derivatives. A series of new 2-aminopyrrole-3-carbonitriles (1a-d) were synthesized from the reaction of benzoin, primary aromatic amines and malononitrile, from which a number of pyrrole derivative...
متن کاملAntifungal Susceptibility of 3,4-di-hydropyrimidine-1-(H2)-L-H1-pyrrole Derivatives in Candida Clinical Isolates
Background and purpose: There is an increasing rate of drug resistance to azole among Candida species, so, finding new compounds that are effective in laboratory conditions, such as 3,4-dihydropyrimidine derivatives are important. The purpose of this study was to evaluate the antifungal sensitivity of 3,4-di-hydropyrimidine-1- (H2) -L- H1-pyrrole derivatives in Candida isolates. Materials and ...
متن کاملOrganocatalytic Asymmetric α-Chlorination of 1, 3-Dicarbonyl Compounds Catalyzed by 2-Aminobenzimidazole Derivatives
Bifunctional chiral 2-aminobenzimidazole derivatives 1 and 2 catalyze the enantioselective stereodivergent α-chlorination of β-ketoesters and 1,3-diketone derivatives with up to 50% ee using N-chlorosuccinimide (NCS) or 2,3,4,4,5,6-hexachloro-2,5-cyclohexadien-1-one as electrophilic chlorine sources.
