Iso-Olomoucine is an inactive stereoisomer of the Cdk5 inhibitor olomoucine.
Cyclin-dependent kinases (CDKs) are reported to be key regulators of cell cycle progression whose function/dysfunction has been implicated in cancer, human neurodegenerative diseases, as well as the response of addictive drugs through alteration of postsynaptic dopamine receptor signaling.
In vitro: In a previous study, rat dorsal striatal synaptosomes were incubation with the Cdk5 inhibitors roscovitine, olomoucine, and GW8510 or the inactive congener iso-olomoucine, which led to a rapid, concentration-dependent inhibition of specific [3H]DA uptake. However, roscovitine was the only inhibitor that did not decrease [3H]2beta-carbomethoxy-3beta-(4-fluorophenyl)tropane binding to dSTR DATs. Roscovitine-induced inhibition of dSTR [3H]DA uptake was demonstrated by decreased maximal uptake velocity, without a change in cell-surface DAT levels. Moreover, roscovitine did not enhance [3H]DA release mediated by either DAT reverse-transport. Instead, roscovitine could enhance spontaneous [3H]DA outflow and inhibit DAT-mediated [3H]DA reaccumulation into dSTR slices. Additionally, in a Cdk5-independent manner, iso-olomoucine was able to rapidly inhibit dopamine transporter activity in rat dorsal striatal synaptosomes with a potency similar to that of olomoucine (IC50 ~37 μM) [1]
In vivo: Up to now, there is no animal in vivo data reported.
Clinical trial: So far, no clinical study has been conducted.
