Bohemine, structurally similar to Olomoucine and Roscovitine, is a novel, potent, selective, and cell-permeable cyclin-dependent kinase (CDK) with IC50s of 4.6, 83, and 2.7 μM for Cdk2/cyclin E, Cdk2/cyclin A, and Cdk9/cyclin T1, respectively. Bohemine exhibits a 52 μM IC50 for ERK2 inhibition, while its impact on CDK1, CDK4, and CDK6 is lessened. The anti-cancer effects of bohemine are wide-ranging.

Biological Activity
| Targets | CDK2/cyclinE (IC50 = 4.6 μM); cdk2/cyclin A (IC50 = 83 μM); CDK9/cyclinT1 (IC50 = 2.7 μM); ERK2 (IC50 = 52 μM) |
| ln Vitro |
Bohemine treatment inhibits cell growth. When bohemine is added at concentrations between 1 and 10 µM, growth and the production of monoclonal antibodies are temporarily stopped. Following the brief suppression of cell functions, there is a notable, transient increase in both the rate of specific growth and production[1]. The G1/S and G2/M boundaries of hybridoma cells are retarded, based on the concentration of bohemine (0-30 µM)[1]. T-cell lymphoblastic line Five proteins are shown to be downregulated when bohemine is used to treat CEM: α-enolase, triosephosphate isomerase, initiation factor 5A, and the α- and β-subunits of Rho GDP-dissociation inhibitor 1. These proteins are important for the processes of glycolysis, proteosynthesis, and cytoskeleton rearrangement[1]. With an IC50 of 27 µM, bohemine inhibits the growth of human tumor cell lines[2]. |
| ln Vivo | Bohemine (50 mg/kg; intravenous injection; BALB/c mice) treatment reveals a T1/2 of 1.39 hours, an observed clearance of 0.23 L/h, and a Cmax of 72,308 nM[2]. |

| Additional Infomation | Bohemine is purine substituted on C-2, C-6 and N-9 with (3-hydroxypropyl)amino, benzylamino and isopropyl groups respectively; a synthetic, cell-permeable, cyclin-dependent kinase (CDK) inhibitor that is structurally similar to olomoucine and roscovitine. It has a role as an EC 2.7.11.22 (cyclin-dependent kinase) inhibitor. |

For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (7.34 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.

Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.
