skf 81297 hydrobromide is a selective agonist of the dopamine d1-like receptor, with a ki value of 1.9 nm. the dopamine d1-like receptors, consisting of d1 and d5 subtypes, are a subfamily of dopamine receptors that mediate excitatory neurotransmission after binding the endogenous neurotransmitter dopamine. the dopamine d1-like receptors have been implicated in dopaminergic regulation of a variety of fundamental neurophysiologic processes including mood, motivation, cognitive function, as well as motor activity.1. neumeyer jl, kula ns, bergman j, baldessarini rj. receptor affinities of dopamine d1 receptor-selective novel phenylbenzazepines. european journal of pharmacology, 2003, 474(2-3): 137-140.2. undieh as. pharmacology of signaling induced by dopamine d(1)-like receptor activation. pharmacology & therapeutics, 2010, 128(1): 37-60.3. vermeulen rj, drukarch b, sahadat mc, et al. the dopamine d1 agonist skf 81297 and the dopamine d2 agonist ly 171555 act synergistically to stimulate motor behavior of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-lesioned parkinsonian rhesus monkeys. movement disorders, 1994, 9(6): 664-672.
