It has been found that readily available 3-benzoylacrylic acids undergo palladium-catalyzed decarboxylative arylation with arylboronic acids in the presence of a copper salt oxidant to produce chalcone derivatives. The decarboxylative arylation could also be achieved using aryl halides as the alternative aryl source to expand the applicable scope.

Process for inhibiting vascularization of a tumor mass comprising administering, in an amount effective to inhibit vascularization, at least one chalcone of formula (I): wherein: R is chosen from a hydrogen atom, a methyl group, an ethyl group, a chlorine atom, and a bromine atom, A is an NR1R2 group, wherein R1 and R2, which may be identical or different, are each chosen from a methyl group and an ethyl group, and n is an integer equal to 2 or 3.
Antimalarial alkoxylated and hydroxylated chalones: Structure-activity relationship analysis
Liu,Wilairat,Go
, p. 4443 - 4452 (2007/10/03)
Chalcones with 2′,3′,4′-trimethoxy, 2′,4′-dimethoxy, 4′-methoxy, 4′-ethoxy, 2′,4′-dihydroxy, and 4′-hydroxy groups on ring B were synthesized and evaluated in vitro against Plasmodium falciparum (K1) in a [3H] hypoxanthine uptake assay. The other ring A was quinoline, pyridine, naphthalene, or phenyl rings with electron-donating or electron-withdrawing substituents of varying lipophilicities. Trimethoxy 6 and 27, dimethoxy 7, 8, 29, and methoxy 31 analogues had good in vitro activities (IC50 5μM). 3-Quinolinyl ring A derivatives were well represented among the active compounds. Hydroxylated chalcones were less active than the corresponding alkoxylated analogues. When evaluated in vivo, 8 and 208 were comparable to chloroquine in extending the lifespan of infected mice. Multivariate data analysis showed that in vitro activity was mainly determined by the properties of ring B. Quantitative structure - activity relationship models with satisfactory predictive ability were obtained for various B ring chalcones using projections to latent structures. A model with good predictability was proposed for 19 active chalcones. Size and hydrophobicity were identified as critical parameters.

A large number of substituted chalcones have been synthesized and tested for antileishmanial and lymphocyte-suppressing activities. A subset of the chalcones was designed by using statistical methods. 3D-QSAR analyses using 67 (antileishmanial activity) and 63 (lymphocyte-suppressing activity) of the compounds for the training sets and 9 compounds as an external validation set were performed by using the GRID/GOLPE methodology. The Smart Region Definition procedure with subsequent region selection as implemented in GOLPE reduced the number of variables to approximately 1300 yielding 3D-QSAR models of high quality (lymphocyte-suppressing model, R2 = 0.90, Q2 = 0.80; antileishmanial model, R2 = 0.73, Q2 = 0.63). The coefficient plots indicate that steric interactions between the chalcones and the target are of major importance for the potencies of the compounds. A comparison of the coefficient plots for the antileishmanial effect and the lymphocyte- suppressing activity discloses significant differences which should make it possible to design chalcones having a high antileishmanial activity without suppressing the proliferation of lymphocytes.
2'-Substituted chalcone derivatives as inhibitors of interleukin-1 biosynthesis

, p. 1434 - 1442 (2007/10/02)
A series of 2'-substituted chalcone derivatives has been found to show potent inhibition of the production of IL-1β from human peripheral blood monocytes stimulated with lipopolysaccharide (LPS), with IC50 values in the 0.2-5.0-μM range. Some members of the series have also shown inhibition of septic shock induced in mice by injection of LPS, although with low potency. Qualitative structure-activity relationships have shown that the enone is required for activity, which may be mediated by conjugate addition of a biological nucleophile to the chalcone. Electron-poor aromatic rings β to the ketone give enhanced potency. Although electronic effects in the other ring (directly attached to the ketone) are minimal, this ring must possess an ortho substituent for good activity without cytotoxicity, suggesting a degree of selectivity which would not be expected for simple, nonspecific alkylating agents.

Certain chalcone derivatives are reported to inhibit the polymerization of tubulin to form microtubules and are therefore antimitotic agents which can be used to control the growth of tumor tissue and can be used as antigout agents.
Chalcones: A new class of antimitotic agents

A series of chalcones was evaluated as antimitotic agents. One of these, (E)-1-(2,5-dimethoxyphenyl)-3-[4-(dimethylamino)phenyl]-2-methyl-2-propen- 1-one) (73), was found to be an effective antimitotic agent at a concentration of 4 nM in an in vitro HeLa
