Side-chain monofluorinated analogs of amphetamine and p-chloroamphetamine. Effects on release of dopamine and 5-hydroxytryptamine from rat striatum.

Monofluorinated analogs of (+/-)-amphetamine and (+/-)-p-chloroamphetamine, in which the methyl group was replaced with a monofluoromethyl group, have pKa values approximately 1.65 units lower than those of their amphetamine counter-parts but retain some ability to stimulate release of dopamine and 5-hydroxytryptamine, respectively, from rat corpus striatum.
