A practical 1,2,3,4-tetrahydroisoquinoline (THIQ)-mediated synthesis of 1,3-disubstituted allenes from terminal alkynes and aldehydes under mild conditions in the presence of CuBr first and then ZnI2 was reported. This telescoped allene synthesis reaction includes three consecutive steps and two reactions: first, a room-temperature CuBr-catalyzed synthesis of propargylamines, exo-yne-THIQs, fro...
Water-soluble compounds of the type [AuCl(PR3)] with alkyl-bis-(m-sulfonated-phenyl)-(mC6H4SO3Na)2 and dialkyl-(m-sulfonated-phenyl)-(mC6H4SO3Na) (R = nBu, Cp) phosphanes have been prepared. Dialkyl-phosphane compounds generate water-soluble nanoparticles of 10-15 nm radius when dissolved in water. These air-stable complexes have been evaluated as catalysts in the synthesis of propargylamines v...
In our search for novel, low-toxic, cell-penetrable and neuroprotective antioxidants, we have designed a number of novel N-propargylamine derivatives of nitroxyl, named "JSAKs". The reactivity and antioxidative potency of two selected JSAKs and their parent nitroxyl against reactive oxygen species (ROS) were examined in vitro, in a cell-free gamma-radiolysis and in model Fenton-type reaction sy...
HIGHLIGHTS ASS2324 is a hybrid compound resulting from the juxtaposition of donepezil and the propargylamine PF9601N ASS2324 is a multi-target directed propargylamine able to bind to all the AChE/BuChE and MAO A/B enzymesASS2324 shows antioxidant, neuroprotective and suitable permeability propertiesASS2324 restores the scopolamine-induced cognitive impairment to the same extent as donepezil, an...
