CDK2 is a member of the eukaryotic S T protein kinase family and its function is to catalyze the phosphoryl transfer of ATP γ-phosphate to serine or threonine hydroxyl (denoted as S0 T0) in a protein substrate.
6-Chloro-2-fluoropurine is a heterocyclic building block.1,2It has been used in the synthesis of purine nucleosides that inhibit cyclin-dependent kinases (CDKs)in vitro.16-Chloro-2-fluoropurine has also been used in the synthesis of purine nucleosides that are active against HIV-1 and hepatitis B virus (HBV)in vitro.2 1.Wilson, S.C., Atrash, B., Barlow, C., et al.Design, synthesis and biological evaluation of 6-pyridylmethylaminopurines as CDK inhibitorsBioorg.

VMY-1-103 is a potent CDK inhibitor, is also a novel dansylated analog of purvalanol B, was shown to inhibit cell cycle progression and proliferation in prostate and breast cancer cells more effectively than purvalanol B. VMY-1-103 , but not purvalanol B, significantly decreased the proportion of cells in S phase and increased the proportion of cells in G(2)/M. VMY-1-103 increased the sub G(1) fraction of apoptotic cells, induced PARP and caspase-3 cleavage and increased the levels of the Death Receptors DR4 and DR5, Bax and Bad while decreasing the number of viable cells, all supporting apoptosis as a mechanism of cell death. VMY-1-103 possesses unique antiproliferative capabilities and that this compound may form the basis of a new candidate drug to treat medulloblastoma.
LSN3106729 hydrochloride, the metabolite of Abemaciclib , is a CDK inhibitor with antitumor activity. LSN3106729 hydrochloride and a CRBN ligand have been used to design PROTAC CDK4/6 degrader[1].

CKD-712 is a nuclear factor NF-kappa B inhibitor. CKD-712 suppressed MMP-9, but not MMP-2 and other NF-κB-regulated proteins involved in cancer metastasis such as VEGF. CKD-712 induced cell cycle arrest at G2M phase by suppressing cyclin A, cyclin B and C
3-Methylthienyl-carbonyl-JNJ-7706621 is a highly potent and selective inhibitor of cyclin-dependent kinase (CDK). It exhibits impressive IC50 values of 6.4 nM and 2 nM for CDK1 cyclin B and CDK2 cyclin A, respectively. Additionally, 3-Methylthienyl-carbonyl-JNJ-7706621 demonstrates potent inhibition against GSK-3 (IC50 = 0.041 μM) and moderate potency towards CDK4, VEGF-R2, and FGF-R2 (IC50 = 0.11 μM, 0.13 μM, and 0.22 μM, respectively). Its applications in cancer research are noteworthy.
