cdk-4-in-1

CDK4 inhibitor is a novel and specific CDK4 Cyclin D1 inhibitor with an IC50 of 10 nM; 1500 and 500 fold than CDK1 Cyclin B (IC50>15 uM) and CDK2 Cyclin A (IC50=5.265 uM) respectively.

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].

Manzamine A hydrochloride is an orally active beta-carboline alkaloid that exhibits specific inhibitory effects on GSK-3β (IC50 = 10.2 μM) and CDK-5 (IC50 = 1.5 μM). Additionally, it targets vacuolar ATPases, leading to the inhibition of autophagy in pancreatic cancer cells. Manzamine A hydrochloride possesses antimalarial and anticancer properties, and also demonstrates potent activity against HSV-1[4].

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].

CDK HDAC-IN-1 exhibits potent inhibitory activity towards CDK2 4 6 and HDAC6, with IC50 values of 60.9 ± 2.9 nM, 276 ± 22.3 nM, 27.2 ± 4.2 nM, and 128.6 ± 0.4 nM, respectively.

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.

EGFR CDK2-IN-4 (compound 4c) is a dual inhibitor targeting EGFR and CDK-2, with IC50 values of 89.6 nM for EGFR and 165.4 nM for CDK-2. It induces apoptosis and S phase cell cycle arrest in MCF-7 cells, showing significant anti-cancer activity with an IC50 of 2.74 μM against MCF-7 cells [1].

CDK2-IN-18 (compound 8q) serves as a powerful inhibitor of CDK 2 E and CDK 4 D1, showing IC50 values of 8 nM and 46 nM, respectively. It effectively inhibits tumor cell proliferation [1].
