cdk1-in-2

CDK1-IN-2 (cdk1 inhibitor 2) is a CDK1 inhibitor with IC50 of 5.8 μM. A broad-spectrum kinase profiling of CDK1-IN-2 revealed nonselective inhibition of several kinases.

CDK1 2 4-IN-1 (compound 3a) is a potent CDK inhibitor with IC50 values of 1.47, 0.78, and 0.87 μM for CDK1, CDK2, and CDK4, respectively. It can be used in cancer research to arrest the cell cycle at the G2 M phase and induce apoptosis, elevating Bax, caspase-3, and P53 levels while decreasing Bcl-2 levels [1].

CDK2-IN-4 is a potent and selective inhibitor of CDK2 with an IC50 of 44 nM for CDK2 cyclin A. It shows 2,000-fold selectivity over CDK1 cyclin B with IC50 of 86 uM.

AZD8421 is a potent and highly selective inhibitor of cyclin-dependent kinase 2 (CDK2) with an IC50 of 9nM, demonstrating greater selectivity over CDK1, CDK4, and CDK6. This compound also exhibits antiproliferative properties by effectively inhibiting Rb phosphorylation. In models of breast and ovarian cancer, AZD8421 has shown significant activity both as a monotherapy and in combination with CDK4 6 inhibitors.

Anticanceragent 264 (Compound 5w) is an anticancer compound that exhibits significant antiproliferative activity in tumor cell lines, with an IC50 range of 7.5-33.67 μM. It notably induces cell cycle arrest at the G2 M phase in MDA-MB-231, MIA PaCa-2, and DU-145 cell lines. This compound reduces key cell cycle proteins CDK1, CDK2, and Cyclin B1 in a dose-dependent manner and has strong binding activity with differentiation inhibitors and DNA-binding proteins. Anticanceragent 264 is useful for research in the cancer disease domain.

JH295 is a highly potent and selective inhibitor of NIMA-related kinase 2 (Nek2), exhibiting irreversible inhibition activity with an IC 50 value of 770 nM. This compound effectively inhibits cellular Nek2 using the alkylation of Cys22. Importantly, JH295 does not exhibit any inhibitory effects toward Cdk1, Aurora B, or Plk1, which are kinases involved in mitotic processes. Furthermore, JH295 has no impact on bipolar spindle assembly or the spindle assembly checkpoint mechanism.

3-Methylthienyl-carbonyl-JNJ-7706621 is a highly potent and selective inhibitor of cyclin-dependent kinase (CDK), showing IC50 values of 6.4 nM for CDK1 cyclin B and 2 nM for CDK2 cyclin A. It also exhibits potent inhibition of GSK-3 (IC50 = 0.041 μM) and moderate inhibition of CDK4, VEGF-R2, and FGF-R2 (IC50 = 0.11 μM, 0.13 μM, and 0.22 μM, respectively), making it significant for cancer research.

CDK HDAC-IN-2 is a potent dual HDAC CDK inhibitor that acts on HDAC1 (IC50: 6.4 nM), HDAC2 (IC50: 0.25 nM), HDAC3 (IC50: 45 nM), HDAC6 and 8 (IC50 > 1000 nM), CDK1 (IC50: 8.63 nM), CDK2 (IC50: 0.30 nM), and CDK4, 6, and 7 (IC50 > 1000 nM). CDK HDAC-IN-2 can arrest the cell cycle in the G2 M phase and induce apoptosis, demonstrating excellent anti-proliferative and significant anti-tumor effects.

CGP74514A is a CDK1 inhibitor with potential anticancer activity. In U937 cells, CGP74514A - induced apoptosis (5 microM) became apparent within 4 hr and approached 100% by 24 hr. The pan- caspase inhibitor Boc-fmk and the caspase-8 inhibitor lETD-fmk opposed CGP74514A -induced caspase-9 activation and PARP degradation, but not cytochrome c or Smac DIABLO release. CGP74514A -mediated apoptosis was substantially blocked by ectopic expression of full-length Bel- 2, a loop-deleted mutant Bcl-2, and Bcl-x(L). CGP74514A treatment (5 microM; 18 hr) resulted in increased p21(CIP1) expression, p27(KIP1) degradation, diminished E2F1 expression, and dephosphorylation of p34(CDC2). It also induced early (i.e., within 2 hr) inhibition of CDK1 activity and dephosphorylation of pRb, followed by pRb degradation, but did not block pRb phosphorylation at CDK2- and CDK4- specific sites. These findings indicate that the selective CDK1 inhibitor, CGP74514A , induces complex changes in cell cycle......

Riviciclib hydrochloride (P276-00) is a novel inhibitor of CDK1, CDK4, and CDK9, with IC50 values of 79 nM, 63 nM, and 20 nM, respectively, currently in Phase 2 3.

CDK4 6-IN-14 is a potent, highly selective inhibitor of Cyclin-Dependent Kinases 4 and 6 (CDK4 6), with inhibition concentrations (IC50s) of 10 nM and 16 nM, respectively. It shows over 60-fold selectivity for CDK4 6 compared to CDKs 1, 2, 7, and 9, and exhibits significant selectivity against 205 other kinases.

LL-K9-3, a selective hydrophobic tagging technology (HyT)-based degrader, specifically targets the CDK9-cyclin T1 complex, displaying DC50 values of 589 nM for cyclin T1 and 662 nM for CDK9. This compound consists of the CDK9 inhibitor, SNS 032, linked to a hydrophobic tag via a glycol linker. Notably, LL-K9-3 does not affect the degradation of other CDKs (CDK1, 2, 4, 5, 6, and 7). Tested in 22RV1 cells, it effectively reduces androgen receptor (AR) and cMyc expression by inducing the selective and synchronous degradation of CDK9 and cyclin T1.

QLT0267 is an inhibitor targeting integrin-linked kinase (ILK; IC50= 26 nM), showing over 10-fold selectivity against cyclin-dependent kinases 1, 2, and 5 (Cdk1, Cdk2, and Cdk5), and over 1,000-fold selectivity against C-terminal Src kinase (CSK), DNA-PK, Pim-1, Akt, PKC, and casein kinase 2 (CK2) at a concentration of 10 mg/ml. This compound effectively inhibits the proliferation of NPA187 papillary thyroid cancer cells with an IC50 of approximately 3 µM and induces apoptosis in NPA187, DRO, and K4 cancer cell lines. In vivo studies reveal that QLT0267, administered at 100 mg/kg, significantly reduces tumor growth in a DRO mouse xenograft model and diminishes both tumor volume and intratumoral vascularization in a U87MG glioblastoma mouse xenograft model, showcasing its potential for therapeutic applications in cancer treatment.

Cyclin-dependent kinase 2 also known as cell division protein kinase 2. The protein encoded by this gene is a member of the cyclin-dependent kinase family of Ser/Thr protein kinases. This protein kinase is highly similar to the gene products of S. cerevis
