Pyrazolobenzodiazepines: Part I. Synthesis and SAR of a potent class of kinase inhibitors
摘要:
A novel series of pyrazolobenzodiazepines 3 has been identified as potent inhibitors of cyclin-dependent kinase 2 (CDK2). Their synthesis and structure-activity relationships (SAR) are described. Representative compounds from this class reversibly inhibit CDK2 activity in vitro, and block cell cycle progression in human tumor cell lines. Further exploration has revealed that this class of compounds inhibits several kinases that play critical roles in cancer cell growth and division as well as tumor angiogenesis. Together, these properties suggest a compelling basis for their use as antitumor agents. (c) 2010 Elsevier Ltd. All rights reserved.
High-throughput screening has shown that Retro-1 inhibits ricin and Shiga toxins by diminishing their intracellular trafficking via the retrograde route, from early endosomes to the Golgi apparatus. To improve the activity of Retro-1, a structure-activity relationship (SAR) study was undertaken and yielded an analogue with a roughly 70-fold better half-maximal effective concentration (EC50) against Shiga toxin cytotoxicity measured in a cell protein synthesis assay.

Aniline-derived diaryliodoniumsalts were synthesized and functionalized in good to excellent yields by judicious utilization of electron-withdrawing protecting groups. This simple approach opens another route to radiolabeling amino arenes in relatively complex molecules, such as flutemetamol.
