  Design, synthesis and biological evaluation of novel (E)-α-benzylsulfonyl chalcone derivatives as potential BRAF inhibitors

  摘要：

  Activating mutations in the BRAF serine/threonine kinase are found in more than 70% of human melanomas, >90% of which are BRAF(V600E). It provides new therapeutic opportunities in malignant melanoma. In silico and in vitro screening of our compound collection has identified Hit 2 as BRAF(V600E) inhibitor. Based on its structure, a series of novel (E)-alpha-benzylsulfonyl chalcone derivatives (13-40) were designed and synthesized. Compound 38 exhibited the most potent inhibitory activity with an IC50 value of 0.17 mu M for BRAF(V600E) and GI(50) value of 0.52 mu M for mutant BRAF-dependent cells. The results of cell based pERK activity and cellular selectivity suggested that those compounds could selectively inhibit proliferation of mutant BRAF-dependent melanoma cell line through inhibition of oncogenic BRAF.

  A highly efficient and enantioselective Ir-catalyzed hydrogenation of unsaturated sulfones was developed. Chiral cyclic and acyclic sulfones were produced in excellent enantioselectivities (up to 98% ee). Coupled with the Ramberg-Bäcklund rearrangement, this reaction offers a novel route to chiral allylic and homoallylic compounds in excellent enantioselectivities (up to 97% ee) and high yields (up

  Cys–Gly, glutathione, and homoglutathione derivatives were synthesized by the Ugi four-component reaction using various benzylthio aldehydes and ketones as carbonyl building blocks. The scope and limitations of the method were investigated. Formation of imidazoline by-products in the Ugi reaction was discussed. 2,2,2-Trifluoroethanol was shown to be a superior reaction media than methanol in some reactions
