Cells were replated at a lower density and analyzed for cell cycle phase distributions, ROS levels, MnSOD expression, and cyclin D1 protein levels.

The honokiol-mediated cell cycle arrest was associated with a decrease in protein levels of cyclin D1, cyclin-dependent kinase 4 (Cdk4), Cdk6, and/or cyclin E and suppression of complex formation between cyclin D1 and Cdk4 as revealed by immunoprecipitation using anti-cyclin D1 antibody followed by immunoblotting for Cdk4 protein.

Cancer Epidemiol. 2009 Jul;33(1):41-6. Epub 2009 May 27.


Their treatment inhibited the migration of damaged DNA induced by UV-B; furthermore, they decreased p21 expression and increased cyclin D1 expression as apoptosis-regulatory genes.

The synergistic effect was mediated through the same mechanism as in SK-7041 alone, involving reduction of cyclin D1 and induction of p21.

Cancer Lett. 2009 May 18;277(2):133-40. Epub 2009 Jan 9.


The honokiol-induced cell cycle arrest was well correlated with the suppressive expression of CDK4, cyclin D1, CDK2, cyclin E, c-Myc, and phosphorylated retinoblastoma protein (pRb) at Ser780.

Correlated well with the induction of apoptosis, obovatol increased the expression of the apoptotic genes; Bax, caspase-3, caspase-9, whereas inhibited expression of anti-apoptotic genes; Bcl-2, inhibitor of apoptosis protein (IAP-1) and X chromosome IAP (XIAP) as well as the cell proliferation marker genes; Cox-2, c-Fos, c-Jun and cyclin D1.

We present the design, synthesis and biological activity of a library of substituted (biphenylcarbonyl)-tryptamine and (biphenylcarbonyl)-tetrahydro-beta-carboline compounds related to the natural product fascaplysin, as novel inhibitors of CDK4/cyclin D1.
The most active compounds have a CDK4 IC (50) in the range 9-11 microM, three of them containing the para-biphenyl plus para-substituents supporting the existence of a pi-stacking pocket within the active site of CDK4.
