[0002] This disclosure relates to the crystal form and preparation method of a condensed tricyclic derivative, belonging to the pharmaceutical field. Background Technology
[0003] Cyclin-dependent kinases (CDKs) are important cellular enzymes that play a crucial role in regulating eukaryotic cell division and proliferation. The catalytic unit of a CDK is known as the activation of the regulatory subunits of cyclins. At least 16 mammalian cyclins have been identified (Annu. Rev. Pharmacol. Toxicol. (1999) 39: 295-312). Cyclin B / CDK1, cyclin A / CDK2, cyclin E / CDK2, cyclin D / CDK4, cyclin D / CDK6, and possibly other heterodynes are important regulators of cell cycle progression. Other functions of cyclin / CDK heterodynes include transcriptional regulation, DNA repair, differentiation, and apoptosis (Annu. Rev. Cell. Dev. Biol. (1997) 13: 261-291).
