Potent and Preferential Degradation of CDK6 via Proteolysis Targeting Chimera Degraders.

ABSTRACT: A focused PROTAC library hijacking cancer therapeutic target CDK6 was developed. A design principle as "match/mismatch" was proposed for understanding the degradation profile differences in these PROTACs. Notably, potent PROTACs with specific and remarkable CDK6 degradation potential were generated by linking CDK6 inhibitor palbociclib and E3 ligase CRBN recruiter pomalidomide. The PROTAC strongly inhibited proliferation of hematopoietic cancer cells including multiple myeloma and robustly degraded copy-amplified/mutated forms of CDK6, indicating future potential clinical applications.

Proteolysis Targeting Chimera Degraders of the METTL3-14 m<sup>6</sup>A-RNA Methyltransferase.

Project description:Methylation of adenine N6 (m6A) is the most frequent RNA modification. On mRNA, it is catalyzed by the METTL3-14 heterodimer complex, which plays a key role in acute myeloid leukemia (AML) and other types of blood cancers and solid tumors. Here, we disclose the first proteolysis targeting chimeras (PROTACs) for an epitranscriptomics protein. For designing the PROTACs, we made use of the crystal structure of the complex of METTL3-14 with a potent and selective small-molecule inhibitor (called UZH2). The optimization of the linker started from a desfluoro precursor of UZH2 whose synthesis is more efficient than that of UZH2. The first nine PROTAC molecules featured PEG- or alkyl-based linkers, but only the latter showed cell penetration. With this information in hand, we synthesized 26 PROTACs based on UZH2 and alkyl linkers of different lengths and rigidity. The formation of the ternary complex was validated by a FRET-based biochemical assay and an in vitro ubiquitination assay. The PROTACs 14, 20, 22, 24, and 30, featuring different linker types and lengths, showed 50% or higher degradation of METTL3 and/or METTL14 measured by Western blot in MOLM-13 cells. They also showed substantial degradation on three other AML cell lines and prostate cancer cell line PC3.

Bridged Proteolysis Targeting Chimera (PROTAC) Enables Degradation of Undruggable Targets.

Project description:Proteolysis Targeting Chimeras (PROTACs) are attractive therapeutic modalities for degrading disease-causing proteins. While many PROTACs have been developed for numerous protein targets, current small-molecule PROTAC approaches cannot target undruggable proteins that do not have small-molecule binders. Here, we present a novel PROTAC approach, termed bridged PROTAC, which utilizes a small-molecule binder of the target protein's binding partner to recruit the protein complex into close proximity with an E3 ubiquitin ligase to target undruggable proteins. Applying this bridged PROTAC strategy, we discovered MS28, the first-in-class degrader of cyclin D1, which lacks a small-molecule binder. MS28 effectively degrades cyclin D1, with faster degradation kinetics and superior degradation efficiency than CDK4/6, through recruiting the CDK4/6-cyclin D1 complex to the von Hippel-Lindau E3 ligase. MS28 also suppressed the proliferation of cancer cells more effectively than CDK4/6 inhibitors and degraders. Altogether, the bridged PROTAC strategy could provide a generalizable platform for targeting undruggable proteins.

Chemically induced degradation of CDK9 by a proteolysis targeting chimera (PROTAC).

Project description:Cyclin-dependent kinase 9 (CDK9), a member of the cyclin-dependent protein kinase (CDK) family, is involved in transcriptional elongation of several target genes. CDK9 is ubiquitously expressed and has been shown to contribute to a variety of malignancies such as pancreatic, prostate and breast cancers. Here we report the development of a heterobifunctional small molecule proteolysis targeting chimera (PROTAC) capable of cereblon (CRBN) mediated proteasomal degradation of CDK9. In HCT116 cells, it selectively degrades CDK9 while sparing other CDK family members. This is the first example of a PROTAC that selectively degrades CDK9.

Proteolysis-targeting chimera (PROTAC) for targeted protein degradation and cancer therapy.

Project description:Proteolysis-targeting chimera (PROTAC) has been developed to be a useful technology for targeted protein degradation. A bifunctional PROTAC molecule consists of a ligand (mostly small-molecule inhibitor) of the protein of interest (POI) and a covalently linked ligand of an E3 ubiquitin ligase (E3). Upon binding to the POI, the PROTAC can recruit E3 for POI ubiquitination, which is subjected to proteasome-mediated degradation. PROTAC complements nucleic acid-based gene knockdown/out technologies for targeted protein reduction and could mimic pharmacological protein inhibition. To date, PROTACs targeting ~ 50 proteins, many of which are clinically validated drug targets, have been successfully developed with several in clinical trials for cancer therapy. This article reviews PROTAC-mediated degradation of critical oncoproteins in cancer, particularly those in hematological malignancies. Chemical structures, cellular and in vivo activities, pharmacokinetics, and pharmacodynamics of these PROTACs are summarized. In addition, potential advantages, challenges, and perspectives of PROTAC technology in cancer therapy are discussed.

Crizotinib-based proteolysis targeting chimera suppresses gastric cancer by promoting MET degradation.

Project description:As one of the common malignant cancer types, gastric cancer (GC) is known for late-stage diagnosis and poor prognosis. Overexpression of the receptor tyrosine kinase MET is associated with poor prognosis among patients with advanced stage GC. However, no MET inhibitor has been used for GC treatment. Like other tyrosine kinase inhibitors that fit the "occupancy-driven" model, current MET inhibitors are prone to acquired resistance. The emerging proteolysis targeting chimera (PROTAC) strategy could overcome such limitations through direct degradation of the target proteins. In this study, we successfully transformed the MET-targeted inhibitor crizotinib into a series of PROTACs, recruiting cereblon/cullin 4A E3 ubiquitin ligase to degrade the MET proteins. The optimized lead PROTAC (PRO-6 E) effectively eliminated MET proteins in vitro and in vivo, inhibiting proliferation and motility of MET-positive GC cells. In the MKN-45 xenograft model, PRO-6 E showed pronounced antitumor efficacy with a well-tolerated dosage regimen. These results validated PRO-6 E as the first oral PROTAC for MET-dependent GC.

Disordered region of cereblon is required for efficient degradation by proteolysis-targeting chimera.

Project description:Proteolysis targeting chimeras (PROTACs) are an emerging strategy for promoting targeted protein degradation by inducing the proximity between targeted proteins and E3 ubiquitin ligases. Although successful degradation of numerous proteins by PROTACs has been demonstrated, the elements that determine the degradability of PROTAC-targeted proteins have not yet been explored. In this study, we developed von Hippel-Lindau-Cereblon (VHL-CRBN) heterodimerizing PROTACs that induce the degradation of CRBN, but not VHL. A quantitative proteomic analysis further revealed that VHL-CRBN heterodimerizing PROTACs induced the degradation of CRBN, but not the well-known immunomodulatory drug (IMiD) neo-substrates, IKAROS family zinc finger 1 (IKZF1) and -3 (IZKF3). Moreover, truncation of disordered regions of CRBN and the androgen receptor (AR) attenuated their PROTAC-induced degradation, and attachment of the disordered region to stable CRBN or AR facilitated PROTAC-induced degradation. Thus, these results suggest that the intrinsically disordered region of targeted proteins is essential for efficient proteolysis, providing a novel criterion for choosing degradable protein targets.

Discovery of the first potent proteolysis targeting chimera (PROTAC) degrader of indoleamine 2,3-dioxygenase 1.

Project description:Cancer immunotherapy is revolutionizing oncology and has emerged as a promising strategy for the treatment of multiple cancers. Indoleamine 2,3-dioxygenase 1 (IDO1), an immune checkpoint, plays an important role in tumor immune escape through the regulation of multiple immune cells and has been regarded as an attractive target for cancer immunotherapy. Proteolysis Targeting Chimeras (PROTAC) technology has emerged as a new model for drug research and development for its advantageous mechanism. Herein, we reported the application of PROTAC technology in targeted degradation of IDO1, leading to the discovery of the first IDO1 PROTAC degrader 2c, which induced significant and persistent degradation of IDO1 with maximum degradation (d max) of 93% in HeLa cells. Western-blot based mechanistic studies indicated that IDO1 was degraded by 2c through the ubiquitin proteasome system (UPS). Label-free real-time cell analysis (RTCA) indicated that 2c moderately improved tumor-killing activity of chimeric antigen receptor-modified T (CAR-T) cells. Collectively, these data provide a new insight for the application of PROTAC technology in tumor immune-related proteins and a promising tool to study the function of IDO1.

BET protein proteolysis targeting chimera (PROTAC) exerts potent lethal activity against Mantle Cell Lymphoma cells

Project description:Bromodomain extraterminal protein (BETP) inhibitors transcriptionally repress oncoproteins and NFkB target genes, which undermines the growth and survival of MCL cells. However, BETi treatment causes accumulation of BETPs, associated with reversible binding and incomplete inhibition of BRD4, which potentially compromises the activity of BETi in MCL cells. Unlike BETi, BET-PROTACs (proteolysis-targeting chimera) ARV-825 and ARV-771 (Arvinas, Inc.) recruit and utilize an E3-ubiquitin ligase to effectively degrade BETPs in MCL cells. BET-PROTACs induce more apoptosis than BETi of MCL cells, including those resistant to ibrutinib. BET-PROTAC treatment induced more perturbations in the mRNA and protein expressions than BETi, with depletion of c-Myc, CDK4, cyclin D1, and the NFkB transcriptional targets Bcl-xL, XIAP and BTK, while inducing the level of HEXIM1, NOXA and CDKN1A/p21. Treatment with ARV-771, which possesses superior pharmacological properties compared to ARV-825, inhibited the in vivo growth and induced greater survival improvement than the BETi OTX015 of immune-depleted mice engrafted with MCL cells. Co-treatment of ARV-771 with ibrutinib or the BCL2-antagonist venetoclax or CDK4/6 inhibitor palbociclib synergistically induced apoptosis of MCL cells. These studies highlight promising and superior pre-clinical activity of BET-PROTAC than BETi, requiring further in vivo evaluation of BET-PROTAC as a therapy for ibrutinib-sensitive or resistant MCL.

RUNX1 knockdown and BET protein proteolysis targeting chimera (PROTAC) exerts potent lethal activity against mtRUNX1 AML cells

Project description:Bromodomain extraterminal protein (BETP) inhibitors transcriptionally repress oncoproteins which undermines the growth and survival of AML cells. However, BETi treatment causes accumulation of BETPs, associated with reversible binding and incomplete inhibition of BRD4, which potentially compromises the activity of BETi in AML cells. Unlike BETi, BET-PROTAC (proteolysis-targeting chimera) ARV-825 recruits and utilize an E3-ubiquitin ligase to effectively degrade BETPs in AML cells. BET-PROTACs induce more apoptosis than BETi of mtRUNX1 AML cells. BET-PROTAC treatment induced more perturbations in the mRNA and protein expressions than BETi. It was noted that treatment with BETi or BET-PROTAC caused significant and sustained depletion of RUNX1 in AML cells. We also determined the effects of global depletion of RUNX1 in mtRUNX1 expressing AML OCI-AML5 cells. We observed an overlap in the signature of RUNX1 knockdown by shRNA with that of OTX015 and ARV-825 in OCI-AML5 cells.

Systematic exploration of different E3 ubiquitin ligases: an approach towards potent and selective CDK6 degraders.

Project description:Cyclin-dependent kinase 6 (CDK6) is an important regulator of the cell cycle. Together with CDK4, it phosphorylates and inactivates retinoblastoma (Rb) protein. In tumour cells, CDK6 is frequently upregulated and CDK4/6 kinase inhibitors like palbociclib possess high activity in breast cancer and other malignancies. Besides its crucial catalytic function, kinase-independent roles of CDK6 have been described. Therefore, targeted degradation of CDK6 may be advantageous over kinase inhibition. Proteolysis targeting chimeras (PROTACs) structurally based on the cereblon (CRBN) ligand thalidomide have recently been described to degrade the targets CDK4/6. However, CRBN-based PROTACs have several limitations including the remaining activity of immunomodulatory drugs (IMiDs) on Ikaros transcription factors as well as CRBN inactivation as a resistance mechanism in cancer. Here, we systematically explored the chemical space of CDK4/6 PROTACs by addressing different E3 ligases and connecting their respective small-molecule binders via various linkers to palbociclib. The spectrum of CDK6-specific PROTACs was extended to von Hippel Lindau (VHL) and cellular inhibitor of apoptosis protein 1 (cIAP1) that are essential for most cancer cells and therefore less likely to be inactivated. Our VHL-based PROTAC series included compounds that were either specific for CDK6 or exhibited dual activity against CDK4 and CDK6. IAP-based PROTACs caused a combined degradation of CDK4/6 and IAPs resulting in synergistic effects on cancer cell growth. Our new degraders showed potent and long-lasting degrading activity in human and mouse cells and inhibited proliferation of several leukemia, myeloma and breast cancer cell lines. In conclusion, we show that VHL- and IAP-based PROTACs are an attractive approach for targeted degradation of CDK4/6 in cancer.
