Roscovitine is a synthetic inhibitor of cyclin-dependent kinases that is currently undergoing clinical trials as a candidate drug for some oncological indications. Its discovery prompted many research teams to further optimize its structure or to initiate their own related but independent studies. This article reviews known roscovitine bioisosteres that have been prepared as CDK inhibitors using different core heterocycles. The individual bioisostere types have been described and explored to a different extent, which complicates direct comparisons of their biochemical activity - only six direct analogs containing different purine bioisosteres have been prepared and evaluated side by side with roscovitine. Only four types of bioisosteres have demonstrated improved biological properties, namely pyrazolo[ 1,5-a]-1,3,5-triazines, pyrazolo[1,5-a]pyrimidines, pyrazolo[1,5-a]pyridines and pyrazolo[4,3-d]pyrimidines.

Deregulation of cyclin-dependent kinases (CDKs) has been associated with many cancer types and has evoked an interest in chemical inhibitors with possible therapeutic benefit. While most known inhibitors display broad selectivity towards multiple CDKs, recent work highlights CDK9 as the critical target responsible for the anticancer activity of clinically evaluated drugs. In this review, we discuss recent findings provided by structural biologists that may allow further development of highly specific inhibitors of CDK9 towards applications in cancer therapy. We also highlight the role of CDK9 in inflammatory processes and diseases.
