- Discovery of a potent inhibitor of MELK that inhibits expression of the anti-apoptotic protein Mcl-1 and TNBC cell growth
-
Despite recent advances in molecularly directed therapy, triple negative breast cancer (TNBC) remains one of the most aggressive forms of breast cancer, still without a suitable target for specific inhibitors. Maternal embryonic leucine zipper kinase (MELK) is highly expressed in TNBC, where level of overexpression correlates with poor prognosis and an aggressive disease course. Herein, we describe the discovery through targeted kinase inhibitor library screening, and structure-guided design of a series of ATP-competitive indolinone derivatives with subnanomolar inhibition constants towards MELK. The most potent compound, 17, inhibits the expression of the anti-apoptotic protein Mcl-1 and proliferation of TNBC cells exhibiting selectivity for cells expressing high levels of MELK. These studies suggest that further elaboration of 17 will furnish MELK-selective inhibitors with potential for development in preclinical models of TNBC and other cancers.

- Indole ketone compound or its derivatives and their use
-
The present invention relates to indolone compounds shown by general formula (a) or derivatives thereof, and uses thereof. The technical problem solved by the present invention is to provide indolone compounds or derivatives thereof, and uses thereof. The present invention uses a deuterium-enriched indolone compound obtained from a deuterium-substituted indolone compound. The above-mentioned indolone compounds can simultaneously effect on three key receptor families involved in the process of blood vessel formation, i.e., vascular endothelial growth factor receptor (VEGFR), fibroblast growth factor receptor (FGFR), and platelet-derived growth factor receptor (PDGFR), and inhibit the formation of blood vessel, thereby achieving the effect of treating cancers. The above-mentioned deuterium-substituted indolone compounds or derivatives thereof have the advantage of high efficiency as medicaments.

- Design, synthesis and biological evaluation of deuterated nintedanib for improving pharmacokinetic properties
-
Nintedanib is a novel triple angiokinase inhibitor that inhibits three growth factors simultaneously. Deuterated derivatives of nintedanib at certain metabolically active sites were prepared and evaluated in vitro and in vivo. In particular, deuterated compound SKLB-C2202 had significantly improved pharmacokinetic properties compared with nintedanib. These efforts lay the foundation for further investigating the druggability of SKLB-C2202. Deuterated derivatives of nintedanib at certain metabolically active sites were prepared and evaluated in vitro and in vivo. Deuterated compound SKLB-C2202 had significantly improved pharmacokinetic properties compared with nintedanib. Further research is underway.

- Photoinduced and N-bromosuccinimide-mediated cyclization of 2-azido-N-phenylacetamides
-
An efficient synthesis of quinoxalin-2(1H)-ones or spiro[cyclohexene-1, 2′-imidazol]-4′-ones has been achieved in moderate to high yields by the visible light-induced and N-bromosuccinimide-mediated cyclization reaction of 2-azido-N-phenylacetamides at ambient temperature. Both the regioselectivity and the speed of cyclization are affected by the substituents attached to the phenyl ring. For example, quinoxalin-2-ones are produced as the main products when the substrates bear electron-withdrawing groups at the para-position of the phenyl ring; in contrast, spiro[cyclohexene-1,2′-imidazol]-4′-ones are obtained as the main products when the substrates bear electron-donating groups at the para-position.

- Synthesis of substituted oxindoles from α-chloroacetanilides via palladium-catalyzed C - H functionalization
-
A novel method for the synthesis of oxindoles is described. In the presence of catalytic palladium acetate and 2-(di-tert-butylphosphino)biphenyl, α-chloroacetanilides are converted to oxindoles in good to excellent yields with high functional group compatibility using triethylamine as a stoichiometric base. The cyclization is highly regioselective, obviating the need for prefunctionalized arenes. Plausible mechanistic pathways for the reaction are discussed. Copyright
