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

The present invention relates to chalcone and chalcone derivatives and analogs which are useful as angiogenesis inhibitors. The present compounds, which are inexpensive to synthesize, exhibit unexpectedly good activity as angiogenesis inhibitors. The present invention also relates to the use of chalcone and its analogs as antitumor/anticancer agents and to treat a number of conditions or disease states in which angiogenesis is a factor, including angiongenic skin diseases such as psoriasis, acne, rosacea, warts, eczema, hemangiomas, lymphangiogenesis, among numerous others, as well as chronic inflammatory disease such as arthritis.
Chalcones can unusually serve as the precursors of acetophenones which then undergo formal (4+1) cyclization with internal alkynes via rhodium(III) catalysis in a regio- and chemoselective manner. 1-Indanones containing quaternary carbon centers along with reusable aryl aldehydes were formed by this annulation. This discovery enables a practical two-step protocol to indanones from the reaction of acetophenones
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.
