good in vivo fungicidal activities against Pseudoperoniospora cubensis and Sphaerotheca fuliginea at the dosage of 200 microg mL(-1). Two compounds, (E)-methyl 2-[2-(3-[(E)-3-(2-chlorophenyl)acryloyl]phenoxy}methyl)phenyl]-3-methoxyacrylate (1e) and (E)-methyl 2-[2-(3-[(E)-3-(3-bromophenyl)acryloyl]phenoxy}methyl)phenyl]-3-methoxyacrylate (1l), were found to display higher fungicidal activities against
Antitumorigenic Activities of Chalcones. I. Inhibitory Effects of Chalcone Derivatives on 32Pi-Incorporation into Phospholipids of HeLa Cells Promoted by 12-O-Tetradecanoyl-phorbol 13-Acetate(TPA).
More than forty chalcone derivatives were synthesized to examine their structure-activity relationship against tumorigenesis. As a primary screening test, the inhibitory activities of the chalcones for the 32Pi-incorporation into phospholipids of HeLa cells enhanced by 12-O-tetradecanoyl-phorbol 13-acetate (TPA) were examined. 3-Hydroxy-chalcone derivatives possessing methyl group in 3'-, 4'-, or 2'-position and isoliquiritigenin homologs showed potent inhibitory activities in the phosphorylation test, which suggests their antitumorigenic effects.
A series of substituted pyrazolines were synthesized and evaluated for their anticancer activity and for their ability to inhibit P-glycoprotein-mediated multidrug resistance by direct binding to a purified protein domain containing an ATP-binding site and a modulator interacting region. Compounds 2a and e have been found to bind to P-glycoprotein with greater affinity.
AbstractA series of novel chalcone derivatives containing a benzothiazole scaffold were synthesized to develop novelantibacterial agents for solving the problem of drug resistance. Most compounds exhibited excellent antibacterial activity against Xanthomonas oryzae pv. Oryzae (Xoo), Xanthomonas axonopodis pv. Citri (Xac), and Ralstonia solanacearum (Rs) compared to a reference drug, bismerthiazol
