Olomoucine is an ATP-competitive CDK inhibitor [1].

Cyclin-dependent kinases (CDKs) play important roles in the regulation of the cell division cycle and are therefore promising targets for cancer therapy [1].

Olomoucine is an ATP-competitive CDK inhibitor with IC50 values of 7, 7, 7, 3 and 25 μM against CDC2/cyclin B, Cdk2/cyclin A and Cdk2/cyclin E kinases, the brain CDK5/p35 kinase and the ERK1/p44 MAP kinase, respectively [1]. In metaphase-arrested Xenopus egg extracts, Olomoucine inhibited M-phase-promoting factor activity. Olomoucine provided an anti-mitotic reagent that might preferentially inhibit certain steps of the cell cycle [1]. In interleukin-2-stimulated T lymphocytes (CTLL-2 cells), Olomoucine inhibited DNA synthesis and caused Gl arrest [2].

In rats after after spinal cord injury (SCI), olomoucine attenuated astroglial proliferation and glial scar formation, decreased lesion cavity and mitigated functional deficits. In rats following SCI, olomoucine significantly decreased the spinal cord edema formation, suppressed microglial proliferation and attenuated production of proinflammatory cytokines in the traumatic spinal cord. Olomoucine also attenuated neuronal cell death [3].
