Nitrogen-containing flavonoids as CDK1/Cyclin B inhibitors: Design, synthesis, and biological evaluation
摘要:
A novel series of nitrogen-containing flavonoids 5a-1, 6a,b, and 7a,b were designed and synthesized as cyclin-dependent kinases (CDKs) inhibitors. The representative compounds 5a, 5b, 5e, and 5g showed potent CDK1/Cyclin B inhibitory activities. All compounds displayed a significant growth inhibitory action in vitro against Bel-7402, PC-3, ECA-109, A-549, HL-60, and MCF-7 cancer cell lines. Flow cytometry analysis showed that 5b induced apoptosis in PC-3 cells. (c) 2006 Published by Elsevier Ltd.

Flavokawain B (1) is a natural chalcone extracted from the roots of Piper methysticum, and has been proven to be a potential cytotoxic compound. Using the partial structure of flavokawain B (FKB), about 23 analogs have been synthesized. Among them, compounds 8, 13 and 23 were found in new FKB derivatives. All compounds were evaluated for their cytotoxic properties against two breast cancer cell lines

substituent on ring A are sufficient for these compounds to have antifungal properties. The chalcone 3‐(2‐chlorophenyl)‐1‐(2′‐hydroxy‐4′,6′‐dimethoxyphenyl)prop‐2‐en‐1‐one, with a Cl atom in the ortho position of benzene ring B showed the best antifungalactivity against standardized strains of Trichophyton rubrum (MIC = 12.5 μg/mL) and inhibited all of the ten clinical isolates of T. rubrum tested (MIC at which

An efficient one-pot method for the synthesis of hydroxyflavanones is described. Methoxychalcones are treated with 36% HBr to afford cyclization and regioselective O-demethylation products (2a-i) while cyclization and complete O-demethylation products (3a-e) are obtained in the presence of 45% HI.

Breast cancer resistance protein (BCRP/ABCG2) belongs to the ATP binding cassette family of transport proteins. BCRP has been found to confer multidrug resistance in cancer cells. A strategy to overcome resistance due to BCRP overexpression is the investigation of potent and specific BCRP inhibitors. The aim of the current study was to investigate different multi-substituted chalcones for their BCRP inhibition. We synthesized chalcones and benzochalcones with different substituents (viz. OH, OCH3, Cl) on ring A and B of the chalcone structure. All synthesized compounds were tested by Hoechst 33342 accumulation assay to determine inhibitory activity in MCF-7 MX and MDCK cells expressing BCRP. The compounds were also screened for their P-glycoprotein (P-gp) and Multidrug resistance-associated protein 1 (MRP1) inhibitory activity in the calcein AM accumulation assay and were found to be selective towards inhibition of BCRP. Substituents at position 20 and 40 on chalcone ring A were found to be essential for activity; additionally there was a great influence of substituents on ring B. Presence of 3,4-dimethoxy substitution on ring B was found to be optimal, while presence of 2- and 4-chloro substitution also showed a positive effect on BCRP inhibition. (C) 2011 Elsevier Ltd.

Antimitotic and Antiproliferative Activities of Chalcones: Forward Structure–Activity Relationship
A series of 59 chalcones was prepared and evaluated for the antimitotic effect against K562 leukemia cells. The most active chalcones were evaluated for their antiproliferative activity against a panel of I I human and murine cell cancer lines. We found that three chalcones were of great interest as potential antimitotic drugs. In vivo safety studies conducted on one of the most active chalcones revealed that the compound was safe, allowing further in vivo antitumor evaluation.
