Cyclin-dependent kinases (CDKs) are key regulators of cell cycle progression and are therefore promising targets for cancer therapy. SNS-032 is an ATP-competitive inhibitor of Cdk9, 2, and 7 with IC₅₀ values of 4, 38, and 62 nM, respectively. It is selective for these kinases and displays no additional activity against a panel of 190 kinases (IC₅₀s = >1,000 nM). SNS-032 can block the cell cycle, inhibit transcription, and induce apoptosis in multiple myeloma RPMI-8226 cells with an IC₉₀ value of 0.3 μM. This compound has been shown to induce apoptosis by inhibiting the transcription of the anti-apoptotic proteins, Mcl-1 and XIAP.

SNS 032 is a selective inhibitor of Cyclin-dependent Kinase (CDK) 2,7, and 9.

ChEBI: N-(5-{[(5-tert-butyl-1,3-oxazol-2-yl)methyl]sulfanyl}-1,3-thiazol-2-yl)piperidine-4-carboxamide is a secondary carboxamide resulting from the formal condensation of the carboxy group of piperidine-4-carboxylic acid with the amino group of 5-{[(5-tert-butyl-1,3-oxazol-2-yl)methyl]sulfanyl}-1,3-thiazol-2-amine. It is an ATP-competitive inhibitor of CDK2, CDK7 and CDK9 kinases and exhibits anti-cancer properties. It has a role as an apoptosis inducer, an antineoplastic agent, an EC 2.7.11.22 (cyclin-dependent kinase) inhibitor and an angiogenesis inhibitor. It is a piperidinecarboxamide, a member of 1,3-oxazoles, a member of 1,3-thiazoles, an organic sulfide and a secondary carboxamide.
