Maintenance of pluripotency in human and mouse embryonic stem cells through activation of Wnt signaling by a pharmacological GSK-3-specific inhibitor
TLDR
It is shown that activation of the canonical Wnt pathway is sufficient to maintain self-renewal of both HESCs and MESCs, and the use of GSK-3-specific inhibitors such as BIO may have practical applications in regenerative medicine.

Biochemical and cellular effects of roscovitine, a potent and selective inhibitor of the cyclin-dependent kinases cdc2, cdk2 and cdk5.
TLDR
Through its unique selectivity for some cyclin-dependent kinases, roscovitine provides a useful antimitotic reagent for cell cycle studies and may prove interesting to control cells with deregulated cdc2, cdk2 or cdk5 kinase activities.

Indirubin, the active constituent of a Chinese antileukaemia medicine, inhibits cyclin-dependent kinases
TLDR
Indirubin-3′-monoxime inhibits the proliferation of a large range of cells, mainly through arresting the cells in the G2/M phase of the cell cycle, which has implications for therapeutic optimization of indigoids.

Phosphorylation of DARPP-32 by Cdk5 modulates dopamine signalling in neurons
TLDR
Dopamine and cyclic AMP-regulated phospho-protein DARPP-32 is a bifunctional signal transduction molecule which, by distinct mechanisms, controls a serine/threonine kinase and aserine/Threonine phosphatase.

Indirubins inhibit glycogen synthase kinase-3 beta and CDK5/p25, two protein kinases involved in abnormal tau phosphorylation in Alzheimer's disease. A property common to most cyclin-dependent kinase…
TLDR
It is reported here that indirubins are also powerful inhibitors (IC(50): 5-50 nm) of an evolutionarily related kinase, glycogen synthase kinase-3beta (GSK-3 beta), and it is shown that many, but not all, reported CDK inhibitors are powerful inhibitors of GSK-3 Beta.

Exploiting chemical libraries, structure, and genomics in the search for kinase inhibitors.
TLDR
Purine libraries could provide useful tools for analyzing a variety of signaling and regulatory pathways and may lead to the development of new therapeutics.

Inhibition of cyclin-dependent kinases by purine analogues: crystal structure of human cdk2 complexed with roscovitine.
TLDR
Results from structure/activity studies and from analysis of the cdk2/roscovitine complex crystal structure should allow the design of even more potent cdk inhibitors.
