fluoroalkyl-containing tropane derivatives was synthesized, and their binding affinities for the dopamine transporter (DAT), serotonin transporter (SERT), and norepinephrine transporter (NET) were determined via competitive binding assays. Among these derivatives, the fluoropropyl ester of beta-CIT (19), the fluoroethyl ester of beta-CIT (20), the N-fluoropropyl derivative of beta-CBT (12), and the fluoropropyl

A series of novel fluoroalkyl-containing tropane derivatives (6-8, 10-14, 17, and 18) were synthesized from cocaine. Novel compounds were evaluated for affinity and selectivity in competitive radioligand binding assays selective for cerebral serotonin (5-HT), dopamine (DA), and norepinephrine (NE) transporters (SERT, DAT, and NET). The nortropane-fluoroalkyl esters (7, 10, 11) were most potent for

A therapeutically effective class of low toxicity aldoxime-substituted functionalized imidazolium compounds and compositions is disclosed which is effective in the treatment of living species poisoned by organophosphorus chemicals which inactivate the enzyme acetylcholinesterase. In vivo administration of therapeutically effective amounts of these aldoxime-substituted imidazolium derivatives has been found to save mammals having inhibited acetylcholinesterase due to injection with lethal dosages of Soman.

The ruthenium catalyzed selective sp(3) C-O cleavage with amide formation was reported in reactions of 3-alkoxy-1-propanol derivatives and amines. The cleavage only occurs at the C3-O position even with 3-benzyloxy-1-propanol. Based on the experimental results, O-bound and C-bound Ru enolate complexes were proposed as key intermediates for the unique selective sp(3) C-O bond cleavage in 3-alkoxy-1-propanols.
