BOHEMINE Chemical Properties,Usage,Production

Definition

ChEBI: 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.

Biological Activity

a highly conserved array of mechanisms regulating cyclin-dependent kinases (cdk), which govern the timing of cell cycle progression and division, has developed in eukaryotes. cdk inhibitors have been shown to play an key regulatory role in cell proliferation, differentiation, senescence, as well as programmed death.

in vitro

bohemine was applied to cultures of mouse hybridoma cells in order to evaluate its capacity of cell growth and the production of monoclonal antibody. results showed that addition of bohemine at concentrations in the range of 1-10 μm led to a short-term arrest of growth and monoclonal antibody production. such short-term suppression of cell functions was followed by a significant temporary increase of specific growth rate and specific production rate. in semicontinuous cultures, the steady-state viable cell density values showed a certain stimulation of cell growth in the presence of bohemine at micromolar concentrations, and growth inhibition at 10 and 30 μm [1].

in vivo

in mice, bohemine was found to be rapidly and completely metabolized and disappeared from circulation during the first 60 min following i.v. administration. moreover, the metabolites were eliminated by the hepatobiliary tract and also by renal excretion [2].
