Problems solved by technology

Representative small molecule inhibitors include Flavopiridol, Roscovitine, SNS-032, R547, TG-02, AT-7519, etc.; however, highly selective small molecule inhibitors targeting CDK7 or CDK9, or targeting CDK7 and CDK9 There are relatively few researches on pharmaceutical agents (US2007179161A1, US2015111873A1, WO2016193939A1, WO2016142855A2)
Although small-molecule inhibitors acting on CDK7 and CDK9 block the cell cycle, induce apoptosis and regulate transcription have become important anti-tumor methods, but recent studies have shown that small-molecule inhibitors acting on CDKs targets appear drug resistance, only through Treatment with Small Molecule Inhibitors Cannot Be an Effective Antitumor Approach
