Dinaciclib(SCH727965) is a potent cyclin-dependent kinase (CDK) inhibitor with IC50 values of 1nM, 1nM, 3nM, and 4nM for CDK2, CDK5, CDK1 and CDK9, respectively[1]. Dinaciclib induces apoptosis by inhibiting the phosphorylation of retinoblastoma protein (Rb) and promoting the accumulation of p85 PARP caspase cleavage product (p85 PARP)[2]. Dinaciclib has been widely used in cancer research to inhibit the growth of various cancer cells[3].
In vitro, Dinaciclib treatment for 96 hours inhibited the viability of Rh41, BT-12 and TC-71 cells, with IC50 values of 10.5nM, 8.5nM and 3.9nM, respectively[4]. Treatment with 500nM Dinaciclib for 24 hours reduced the expression of the anti-apoptotic protein Mcl-1 in HL-60 cells and induced the cleavage of the PARP protein, promoting cell cycle arrest[5]. 8nM of Dinaciclib incubation for 24 hours inhibited the proliferation of HuCCT1 cells, resulting in a decrease in the proportion of cells in the S phase, accompanied by an increase in caspase3/7 activity[6].
In vivo, Dinaciclib treatment via intraperitoneal injection at a dose of 30mg/kg, twice a week for 6 weeks, prolonged the survival period of bearing Eμ-Myc and IG-cMYC-translocated lymphomas[7]. Intraperitoneal injection of Dinaciclib at a dose of 20mg/kg daily for 21 consecutive days inhibited tumor growth and suppressed the phosphorylation of Rb (Ser807/811) and RNA polymerase II (Ser2) in tumor tissues in SH-SY5Y xenograft mice[8].

Protocol
| Cell experiment [1]: | |
|
Cell lines |
HuCCT1 cells |
|
Preparation Method |
HuCCT1 cells were RPMI-1640 medium supplemented with 100μg/ml streptomycin, 100μg/ml penicillin and 5% fetal bovine serum at 37°C in an incubator with 5% CO2. HuCCT1 cells (2×103/well) were seeded in the 96-well plates and cultured overnight followed by treatment with different concentrations of Dinaciclib (0, 1, 5, 10, 20, and 30nM) for 24h. Cells viability was measured. |
|
Reaction Conditions |
0, 1, 5, 10, 20, and 30nM; 24h |
|
Applications |
Dinaciclib reduced cell viability of HuCCT1 in a dose-dependent manner. |
| Animal experiment [2]: | |
|
Animal models |
Athymic NCR nude mice |
|
Preparation Method |
Athymic NCR nude mice were housed in cages and maintained in air-conditioned animal quarters with a 12h light-dark cycle and free access to autoclaved tap water and a standard chow diet. A transverse incision was generated over the left flank of the nude mice, and 1.5×106 luciferase-transduced SH-SY5Y cells, which were diluted in 0.1ml of PBS, were surgically injected into the left renal capsule and toward the superior pole of the left kidney of the nude mice. After allowing the injected mice to engraft for 2 to 3 weeks, tumor-bearing mice with similar sizes (using bioluminescent imaging to monitor the tumor size) were randomly divided into two groups: a DMSO control group and a Dinaciclib treated group (20mg/kg by intraperitoneal injection once daily for 21 days). Each group contained four mice with SH-SY5Y-luciferase tumors. At the end of the treatment, all mice were sacrificed. Tumors and the right kidneys (control) were harvested, weighed and photographed. |
