series of 20 chalcone derivatives was synthesized, and their antiproliferative activity was tested against the human Tcellacutelymphoblasticleukemia‐derivedcell line, CCRF‐CEM. On the basis of the structural features of the most active compounds, a new library of chalcone derivatives, according to the structure–activity relationship design, was synthesized, and their antiproliferative activity was
Major anti-inflammatoryagents, steroids and cyclooxygenase, were proved to have serious side effects. Here, a series of chalconederivatives were synthesized and screened for anti-inflammatory activities. QSAR study revealed that the presence of electron-withdrawing groups in B-ring and electron-donating groups in A-ring of chalcones was important for inhibition of LPS-induced IL-6 expression. Further

Disclosed are compounds which are nuclear receptor modulators that can act as antagonists to the androgen receptor, for example, a compound of Formula I: wherein R1 to R5 and X1 to X5 are as described herein, as well as pharmaceutically acceptable salts, solvates, and stereoisomers thereof. Pharmaceutical compositions comprising such compounds, as well as methods of use, and treatment for cancers, including prostate cancers, other nuclear receptor mediated cancers, and other conditions, are also disclosed.
to 9 kbar) allows for relatively fast (1–5 h) and highlyenantioselective 1,4-addition of nitromethane and 2-nitropropane to chalcones at room temperature with substantial reduction of catalyst loading (0.2–1 mol% of cinchonaalkaloid-based thioureas and squaramides). Various γ-nitroketones were obtained at 9 kbar with high yield and enantioselectivity (up to 98%), whereas in control experiments at atmospheric

A robust and stable Ru-Biphosphinobioxazoline catalystsystem is discovered for the highly enantioselective hydrogenation of enones to allylicalcohols. A series of acyclic α,β-unsaturated ketones react well affording the desired products in high yields (up to 98%) and enantioselectivities (up to 98% ee). Simple manipulation process and tolerance of water and air make this catalysis more practical
