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
synthesized through the azide/alkyne dipolar cycloaddition. Hybrid molecules were evaluated for their cytotoxic activity against four cancer cell lines (e.g., HuCCA-1, HepG2, A549 and MOLT-3) and antimalarial activity toward Plasmodiumfalciparum. Most of the synthesized hybrids, except for analogs 10 and 16, displayed cytotoxicity against MOLT-3 cell line without affecting normal cells. Analogs (10

L'invention concerne une composition filtrante, notamment cosmétique, pour la protection d'une matière sensible contre le rayonnement ultraviolet, une telle composition comprenant une quantité efficace d'au moins un dérive azoté de chalcone de formule (I). L'invention concerne, encore, un procédé de protection d'une matière sensible contre le rayonnement ultraviolet, un procédé de fabrication de fibres ou de polymères textiles pour la protection contre un tel rayonnement ainsi qu'un médicament pour la prévention des effets néfastes d'un tel rayonnement et faisant appel à au moins un dérivé azoté de chalcone de formule (I).
Discovery and evaluation of chalcone derivatives as novel potential anti-Toxoplasma gondii agents
Due to numerous side effects of traditional treatments for toxoplasmosis, it is urgent to develop new anti-Toxoplasma agents with high efficiency and low toxicity. In this study, using drug-food-homologous chalcone skeleton as a leading compound, 6 series of chalconederivatives were designed, synthesized, and almost 1/2 compounds have good anti-Toxoplasma activity in vitro. The quantitative structure-activity
