GtoPdb Ligand ID: 10095

Synonyms: RO-3306
Compound class: Synthetic organic
Comment: The selectivity profile of RO3306 (structure reported in [2]) suggests that is the most suitable CDK1 chemical probe to be reported (as of October 2018) [1]. Additional non-CDK off-targets that should be considered when interpreting experimental results include PKCδ (Ki 318 nM), SGK (Ki 497 nM) and ERK (Ki 1980 nM) [2].

Bioactivity Comments
RO3306 arrests HCT-116 colon carcinoma cells in the G2/M phase of the cell cycle, which is consistent with inhibition of CDK1 [1].
