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 angiogenic skin diseases such as psoriasis, acne, rosacea, warts, eczema, hemangiomas, lymphangiogenesis, among numerous others, as well as chronic inflammatory disease such as arthritis.

In this study, we investigated the effects of 24 chalcone derivatives from 2-naphthylacetophenone toward a lymphoblastic leukemia cell line (L1210). Three compounds, called R7, R13, and R15, presented concentration- and time-dependent cytotoxicity and induced cellular death by apoptosis via mitochondrial injury and oxidative stress. The effects of these compounds appear to occur through different mechanisms because R13 and R7 induced a greater disturbance of mitochondrial potential, and all compounds induced disturbances of cellular ATP content and increased caspase-3 activity before cellular death. These compounds also interfered with antioxidant enzymes activities and GSH content through different mechanisms. (C) 2010 Elsevier Ltd. All rights reserved.
Chiral recognition and molecular interaction in cellulose derivatives
Nineteen 1,3-bis(aryl)propane derivatives and six model compounds with a single chromophore were used to explore the chiral discrimination ability of cellulose derivatives, in particular cellulose triphenylcarbamate (CTC), in connection with the mode of interaction of these probe molecules with adsorbents. The interaction was evaluated by conformational analysis of the probe molecules and circular dichroism. Thc 1,3-bis(aryl)propanes with 9-anthryl moieties possessed a highly limited conformation owing to thc bulky substituent and hardly changed their shape on CTC as evidenced by CD spectra; thus, they may be regarded as ''rigid'' substrates. However, these ''rigid'' substrates were resolved quite effectively. On the other hand, those with 2-naphthyl moieties possessed a number of stable conformations and could change their shape in diastereomeric complexes on CTC; thus, they may be assumed as ''soft'' substrates, against which the chiral discrimination was inefficient. The present study revealed that the optical resolution may be interpreted at least partly in terms of the ''rigid'' and ''soft'' concept.
