It has been specifically shown to be an effective inhibitor of angiogenesis both in vitro and in vivo. Using curcumin as a lead compound for anti-angiogenic analog design, a series of structurally related compounds utilizing a substituted chalcone backbone have been synthesized and tested via an established SVR cell proliferation assay. The results have yielded a wide range of compounds that equal or

elemental analysis). All chalcones were evaluated for their cytotoxic action against the cancer cell lines, MCF-7 and HepG2. One 2-pyridyl-substituted compound 14 with IC50 values 17.4±0.2 towards MCF-7 and 15.4±0.6µmol L-1 towards HepG2 cells. Results: The results demonstrated that the cytotoxicactivity of 2-pyridyl-substituted compound shown higher activity as compared with the standard cisplatin
Under the high-speed vibration milling conditions, K2CO3 was found to be a very efficient catalyst for the solvent-free Michael reactions of 1,3-dicarbonyl compounds with chalcones and azachalcones. In most cases, conventional side reactions were avoided and thus excellent yields were achieved. The influences of other catalysts and the vibration frequency on the Michael reaction were investigated.

A series of new 2,2′-bipyridine derivatives were synthesized via three-component reactions of 3-aryl-1-(pyridin-2-yl)prop-2-en-1-ones, malononitrile, and aromatic amines in DMF under microwave irradiation. It is an efficient and promising synthetic strategy to construct 2,2′-bipyridine skeleton.
Mechanochemical Michael Reactions of Chalcones and Azachalcones with Ethyl Acetoacetate Catalyzed by K<sub>2</sub>CO<sub>3</sub>under Solvent-Free Conditions
addition reactions of chalcones and azachalcones with ethylacetoacetate have been successfully performed in the presence of catalytic amount of K 2 CO 3 (10 mol %) and under the high-speed vibration milling conditions. The reactions take place at ambient temperature without any solvent and full completion can be achieved in very short time (20-40 min). In most cases, conventional side reactions were avoided
查耳酮和氮杂查耳酮与乙酰乙酸乙酯的迈克尔加成反应在催化量的K 2 CO 3 (10 mol %)存在下和高速振动研磨条件下成功进行。反应在环境温度下进行,无需任何溶剂,可以在很短的时间内(20-40 分钟)完全完成。在大多数情况下,避免了传统的副反应,从而实现了高化学选择性和定量收率。所需的迈克尔加合物仅由两种非对映异构体 anti 和 syn 组成,它们通过 1 H NMR 光谱测定和指定。
