CDK7 inhibitors as anticancer drugs
Cancer Metastasis Rev 2020 Sep;39(3):805-823.PMID:32385714DOI:10.1007/s10555-020-09885-8.
Cyclin-dependent kinase 7 (CDK7), along with cyclin H and MAT1, forms the CDK-activating complex (CAK), which directs progression through the cell cycle via T-loop phosphorylation of cell cycle CDKs. CAK is also a component of the general transcription factor, TFIIH. CDK7-mediated phosphorylation of RNA polymerase II (Pol II) at active gene promoters permits transcription. Cell cycle dysregulation is an established hallmark of cancer, and aberrant control of transcriptional processes, through diverse mechanisms, is also common in many cancers. Furthermore, CDK7 levels are elevated in a number of cancer types and are associated with clinical outcomes, suggestive of greater dependence on CDK7 activity, compared with normal tissues. These findings identify CDK7 as a cancer therapeutic target, and several recent publications report selective CDK7 inhibitors (CDK7i) with activity against diverse cancer types. Preclinical studies have shown that CDK7i cause cell cycle arrest, apoptosis and repression of transcription, particularly of super-enhancer-associated genes in cancer, and have demonstrated their potential for overcoming resistance to cancer treatments. Moreover, combinations of CDK7i with other targeted cancer therapies, including BET inhibitors, BCL2 inhibitors and hormone therapies, have shown efficacy in model systems. Four CDK7i, ICEC0942 (CT7001), SY-1365, SY-5609 and LY3405105, have now progressed to Phase I/II clinical trials. Here we describe the work that has led to the development of selective CDK7i, the current status of the most advanced clinical candidates, and discuss their potential importance as cancer therapeutics, both as monotherapies and in combination settings.

Discovery and Characterization of SY-1365, a Selective, Covalent Inhibitor of CDK7
Cancer Res 2019 Jul 1;79(13):3479-3491.PMID:31064851DOI:10.1158/0008-5472.CAN-19-0119.
Recent studies suggest that targeting transcriptional machinery can lead to potent and selective anticancer effects in cancers dependent on high and constant expression of certain transcription factors for growth and survival. Cyclin-dependent kinase 7 (CDK7) is the catalytic subunit of the CDK-activating kinase complex. Its function is required for both cell-cycle regulation and transcriptional control of gene expression. CDK7 has recently emerged as an attractive cancer target because its inhibition leads to decreased transcript levels of oncogenic transcription factors, especially those associated with super-enhancers. Here, we describe a selective CDK7 inhibitor SY-1365, which is currently in clinical trials in populations of patients with ovarian and breast cancer (NCT03134638). In vitro, SY-1365 inhibited cell growth of many different cancer types at nanomolar concentrations. SY-1365 treatment decreased MCL1 protein levels, and cancer cells with low BCL2L1 (BCL-XL) expression were found to be more sensitive to SY-1365. Transcriptional changes in acute myeloid leukemia (AML) cell lines were distinct from those following treatment with other transcriptional inhibitors. SY-1365 demonstrated substantial antitumor effects in multiple AML xenograft models as a single agent; SY-1365-induced growth inhibition was enhanced in combination with the BCL2 inhibitor venetoclax. Antitumor activity was also observed in xenograft models of ovarian cancer, suggesting the potential for exploring SY-1365 in the clinic in both hematologic and solid tumors. Our findings support targeting CDK7 as a new approach for treating transcriptionally addicted cancers. SIGNIFICANCE: These findings demonstrate the molecular mechanism of action and potent antitumor activity of SY-1365, the first selective CDK7 inhibitor to enter clinical investigation.
Cyclin dependent kinase (CDK) inhibitors as anticancer drugs: Recent advances (2015-2019)
Bioorg Med Chem Lett 2019 Oct 15;29(20):126637.PMID:31477350DOI:10.1016/j.bmcl.2019.126637.
Sustained proliferative capacity and gene dysregulation are hallmarks of cancer. In mammalian cells, cyclin-dependent kinases (CDKs) control critical cell cycle checkpoints and key transcriptional events in response to extracellular and intracellular signals leading to proliferation. Significant clinical activity for the treatment of hormone receptor positive metastatic breast cancer has been demonstrated by palbociclib, ribociclib and abemaciclib, dual CDK4/6 inhibitors recently FDA-approved. SY-1365, a CDK7 inhibitor has shown initial encouraging data in phase I for solid tumors treatment. These results have rejuvenated the CDKs research field. This review provides an overview of relevant advances on CDK inhibitor research since 2015 to 2019, with special emphasis on transcriptional CDK inhibitors, new emerging strategies such as target protein degradation and compounds under clinical evaluation.
CDK7 Inhibitors in Cancer Therapy: The Sweet Smell of Success?
J Med Chem 2020 Jul 23;63(14):7458-7474.PMID:32150405DOI:10.1021/acs.jmedchem.9b01985.
Cyclin-dependent kinase (CDK) 7 has a unique functional repertoire by virtue of its dual role in transcription and cell cycle progression. Whereas CDK7 is ubiquitously expressed in various types of cancer, its downregulation leads to reduced cell proliferation. Importantly, it is now agreed that targeting transcription selectively limits the synthesis of mRNAs involved in tumor growth without causing an outage of transcription of housekeeping genes. Thus, CDK7 has been considered as a viable therapeutic target in cancer. Indeed, the development of CDK7 inhibitors has gained huge momentum with two molecules, CT7001 and SY-1365, currently under clinical development. Herein, we discuss the latest understanding of the role of CDK7 in cancer cells and provide an overview of the pharmacophores of CDK7 inhibitors, their efficacy in various cancer models, and their clinical development.
