synthesizing 1,3-enynes without prefunctionalized building blocks. In this transformation several classes of unactivated internal acceptor alkynes can be coupled with terminal donor alkynes to deliver 1,3-enynes in a highly regio- and stereoselective manner. The scope of compatible acceptor alkynes includes propargyl alcohols, (homo)propargyl amine derivatives, and (homo)propargyl carboxamides. This method is
There is provided medicaments, particularly a vascular endothelial growth factor (VEGF) inhibitor which is useful as a therapeutic drug for solid tumors, diabetic retinopathy and the like diseases in which angiogenesis is taking a role. That is, since a novel 3-quinolin-2(1H)-ylideneindolin-2-one derivative or a salt thereof has good VEGF inhibitory action, angiogenesis inhibitory action and anti-tumor action, it is useful as ideal VEGF inhibitor, angiogenesis inhibitor and anti-tumor agent.

Diarylquinolines represent a new class of antibiotics with high potency against Mycobacterium tuberculosis. As such, they are of utmost importance in the treatment of drug-resistant bacterial pathogens. In this work, we report a strategy for preparing fluorescently labeled derivatives of the FDA-approved diarylquinoline-based tuberculosis drug bedaquiline. The labeled compounds were capable of blocking
A series of nicotinic ligands, carrying a quinoline nucleus, and characterized by a pharmacophoric distance between the quinoline nitrogen (H-bond acceptor) and the cationic nitrogen atoms higher than that proposed in the classical pharmacophoric models, have been synthesized and tested for their affinity for the central nicotinic receptor. The enantiomers of the nicotine analogue 1-methyl-2-pyrrolidinyl-6-quinoline
