SKF 38393 Hydrochloride is a D1 receptor agonist.

skf38393 hcl (skf38393) is a selective dopamine d1 receptor agonist [1], with an ic50 value of 110 nm [2].there are two functional types of dopamine receptors, d1 and d2 receptors [3]. the stimulation of the d1 receptor (d1r) in prefrontal cortex (pfc) results in an ‘inverted-u’ dose-response. either too little or too much d1r stimulation can impair spatial working memory [4].6-ohda reduced the specific expression of mrnas to encode substance p and d1 dopamine receptor in striatonigral neurons. subsequently daily injections of skf-38393 reversed this reduction effect. the treatment with skf-38393 also increased dynorphin mrna [5]. d1rs activate cyclic amp-dependent protein kinases, stimulate adenylyl cyclase, regulate neuron growth and differentiation, modify dopamine d2 receptor-mediated events and influence behavior [3]. in a 96-well plate assay, the plating of mcf-7 cells was involved in the breast cancer in vitro screening procedure. after 1 day, treatment with skf 38393 was applied to cells for 2 days. data showed that skf 38393 significantly decrease the proliferation of mcf-7 cells. the ic50 value was 0.1 +/- 0.03 μm [6].in locally anesthetized, artificially respired, gallamine-treated rats, i.v. administration of skf 38393 significantly altered dopamine cell activity. in these rats, firing rate increases and decreases were also observed [7].

(±)-SKF-38393 is a D1 dopamine receptor agonist. It is known to promote the production of glutamate in the hippocampus.
