Design, synthesis and biological evaluation of new arylpiperazine derivatives bearing a flavone moiety as α1-adrenoceptor antagonists
摘要:
Elaborate study on the three-dimensional model of alpha(1)-adrenoceptor (alpha(1)-AR) antagonists led to the development of a series of new arylpiperazine derivatives bearing a flavone nucleus as alpha(1)-AR antagonists. The in vitro activities were evaluated and compounds 1, 4, 10, 13 and 15 showed activities close to the reference compound (Prazosin). (C) 2010 Elsevier Ltd. All rights reserved.
Synthesis, biopharmaceutical characterization, antimicrobial and antioxidant activities of 1-(4′-O-β-d-glucopyranosyloxy-2′-hydroxyphenyl)-3-aryl-propane-1,3-diones
摘要:
This research communication is toward the investigation of the antibacterial, antifungal and antioxidant activities of the synthesized compounds 1-(4'-O-beta-D-glucopyranosyloxy-2'-hydroxyphenyl)-3-aryl-propane-1,3-diones (5a)-(5h). These compounds have been obtained by the interaction of alpha-acetobromoglucose with 1-(2',4'-dihydroxyphenyl)-3-aryl-propane-1,3-diones (3a)-(3h) under anhydrous condition and at lower temperature. The structures of these newly synthesized O-beta-D-glucopyranosides were established on the basis of chemical, elemental, and spectral analyses. Further, the compounds (5b), (5c), (5d) and (5g) showed potent antibacterial and antifungal activity. A good correlation was obtained between the theoretical predictions of bioavailability using Lipinski's rule-of-five and experimental verification. (c) 2011 Elsevier Masson SAS. All rights reserved.
