A series of flavonoid derivativescontaining thiazole scaffold were designed, synthesized and evaluated for their inhibition effects against Rhizoctonia solani, Fusarium graminearum, Gaeumannomyces graminis, Alternaria solani, Botrytis cinerea, and Alternaria mali. The antifungal bioassays results in vitro indicated that some target compounds showed good antibacterial activity against the tested plant
Central neuromedin U 2 receptor (NMU2R) plays important roles in the regulation of food intake and body weight. Identification of NMU2R agonists may lead to the development of pharmaceutical agents to treat obesity. Based on the structure of rutin, a typical flavonoid and one of the NMU2R agonists we previously identified from an in-house made natural product library, 30 flavonoid derivatives have been synthesized and screened on a cell-based reporter gene assay. A number of compounds were found to be selective and highly potent to NMU2R. For example, the EC50 value of compound NRA 4 is very close to that of NMU, the endogenous peptide ligand of NMU2R. Structure-activity relationship analysis revealed that a 3-hydroxyl group in ring C and a 2'-fluoride group in ring B were essential for this class of compounds to be active against NMU2R.
