最終版 學會議程

3月8日(日)

泛素基礎分解後的展望

12:50 Organizer’s Welcome Remarks

13:00 Chairperson’s Remarks

Markus Queisser, PhD, Scientific Leader, Protein Degradation DPU, R&D Future Pipelines Discovery, GlaxoSmithKline

13:05 以自然形式利用細胞分解機制

Laura Itzhaki, FRSC, Professor of Structural Pharmacology, Department of Pharmacology, University of Cambridge; CSO, PolyProx Therapeutics

The common underpinning basis of the cell’s proteostasis network is molecular recognition involving the specific interactions of proteins with one another. The Polyproxin™ platform exploits our understanding of these interactions to harness proteostasis networks and thereby manipulate protein stability and disease outcome. The platform comprises libraries of target-engagement modules and degradation-inducing modules in a mix-and-match format to identify the best combination for effective knockdown of the target. The platform can thereby be directed to diverse targets and disease states by co-opting the broadest range of degradation machineries including, but not limited to, the ubiquitin-proteasome system.

13:35 除了分解以外,使用應對PROTAC的泛素訊號的方法

Tauseef R. Butt, PhD, President and CEO, Progenra, Inc.

Nature synthesizes multiple poly-ubiquitin chains that extend from seven lysines on the ubiquitin surface. Lys 48 and Lys 63 poly-ubiquitin are primary degradation signals for PROTACs, driven by ubiquitin ligases cereblon, VHL and HDM2. Little is known about the roles of mono-ubiquitin or atypical poly-ubiquitin chains or their cognitive ubiquitin ligases. The roles of classic ubiquitin ligases and atypical ubiquitylation will be discussed with the aim of expanding the horizon of PROTAC drugs beyond protein degradation.

14:05 Looking beyond Degradation: What Cellular Pathways Can We Explore and Exploit?

Discussion with Session Speakers

14:35 Sponsored Presentation (Opportunity Available)

15:05 Opening Refreshment Break

特別會議:尋求新的連接酶

15:35 FEATURED PRESENTATION: 用於PROTAC開發的工具箱擴充

Alex Bullock, PhD, Associate Professor, Nuffield Department of Medicine, University of Oxford; Principal Investigator, Structural Genomics Consortium (SGC)

The discovery of PROTACs remains empirical and can fail due to the limited choice of E3s. To date only ~1% of the 600 E3s have been explored for PROTACs. We are developing chemical handles for an expanded set of E3s with distinct structural properties as well as diverse temporal and spatial expression profiles to expand the potential applications of PROTACs for chemical biology and broaden the horizon for future drug discovery efforts.

16:05 為了鑑定可分解目標蛋白質的新E3泛素連接酶而開發的表現型非依賴手法

Markus Queisser, PhD, Scientific Leader, Protein Degradation DPU, R&D Future Pipelines Discovery, GlaxoSmithKline

We report a novel, unbiased, phenotypic screening approach for the identification of such chemical matter. The key concept of the assay is the chemical modification of screening compounds and the evaluation of their ability to recruit E3 ligases by a simple fluorescence-based readout in an easy to setup cellular screening system. This combines, for the first time, high-throughput chemistry with high-content screening in living cells.

16:35 以Affinity-directed PROtein Missile (AdPROM)系統分解目標蛋白質

Gopal Sapkota, PhD, Programme Leader, MRC Protein Phosphorylation & Ubiquitylation Unit, Sir James Black Centre, School of Life Sciences, University of Dundee

The AdPROM system utilizes E3 ubiquitin ligases linked to small, polypeptide binders of intracellular proteins of interest (POIs) as protein missiles to target the destruction of the POIs through the proteasome. The system achieves rapid and efficient degradation of target POIs and is versatile. The AdPROM system can not only degrade POIs but also rapidly inform whether different E3 ligases are capable of degrading POIs.

17:05 Exploring New Ligases and Degradation Pathways

尋求用於分解研究的適當測定

8:30 Chairperson’s Remarks

Roy Pollock, PhD, Senior Vice President, Biology, C4 Therapeutics

8:40 目標蛋白質分解誘導作為新的治療方法

Roy Pollock, PhD, Senior Vice President, Biology, C4 Therapeutics

The ability to direct proteins for degradation by the ubiquitin-proteasome system using heterobifunctional small molecules has created a unique opportunity to treat human diseases. Targeted protein degradation (TPD) offers the potential for more profound ablation of protein function and broadens the spectrum of addressable therapeutic targets. In this presentation, I will use BRD4 as a case study to illustrate our approach to TPD including the critical assays used and how they inform on degrader development.

9:10 使應對癌症困難目標的分解藥開發成為可能的大規模蛋白質組的途徑

Katherine Donovan, PhD, Scientist, Laboratory of Dr. Eric Fischer, Cancer Biology, Dana-Farber Cancer Institute/Harvard Medical School

Small molecules that induce protein degradation through ligase-mediated ubiquitination have shown considerable promise as a new pharmacological modality. We and others have demonstrated that efficacious degradation of kinases and other targets can be achieved in vitro and in vivo, however, many targets remain recalcitrant to degradation. In this presentation, I will discuss the use of large-scale chemical-proteomics approaches to accelerate the development of degraders as novel chemical probes for kinases and other disease targets.

9:40 Sponsored Presentation (Opportunity Available)

10:10 Coffee Break

FINDING NOVEL DEGRADERS

10:40 Cullin-RING泛素連接酶與去除低分子誘發性目標

Yue Xiong, PhD, William R. Kenan Jr. Professorship of Biochemistry and Biophysics, University of North Carolina; Co-Founder, Cullgen

Development of small molecules to target ubiquitin-dependent degradation of disease-linked proteins represents a promising opportunity for the drug discovery. Multiple such small molecules have been developed based on different E3 ubiquitin ligases. I will discuss the catalytic mechanism, assembly and regulation of cullin-RING E3 ubiquitin ligases (CRLs). I will also present our efforts in developing novel degraders targeting different human cancer protein. Finally, I will share the thoughts on developing novel E3 ligands.

11:10 目標蛋白質分解誘導作為新的治療藥物型態

Nikki Carter, PhD, Associate Director, Discovery Biology, AstraZeneca

This presentation will highlight internal efforts to build state-of-the-art assay cascades towards understanding the molecular mechanism underlying this intriguing biology, the build of a proteomics platform to define the binding and degradation selectivity of protein degraders and the hit finding for novel E3 ligase ligands. The identification of novel degraders against two oncogenic targets and their utility as target validation tools and as potential therapeutics for many solid and haematological malignancies will be described.

11:40 Structure-Based Design of a Macrocyclic PROTAC

Andrea Testa, PhD, Head of Chemistry, Amphista Therapeutics Ltd.

Constraining a molecule in its bioactive conformation via macrocyclization represents an attractive strategy that to date remains unprecedented for bifunctional molecules such as PROTAC degraders. The talk will illustrate the design, synthesis, biophysical studies and crystal structure of a macrocyclic PROTAC targeting BET proteins.

12:10 Luncheon Presentation (Sponsorship Opportunity Available) or Enjoy Lunch on Your Own

分解藥的設計與提升特異性

13:10 Chairperson’s Remarks

Nikki Carter, PhD, Associate Director, Discovery Biology, AstraZeneca

13:15 為了改善PROTAC的E3連接酶活性化

Jacky Chung, PhD, Scientist, Laboratory of Dr. Sachdev Sidhu, Donnelly Center, University of Toronto

Although the development of PROTACs has garnered significant attention, several challenges remain, including therapeutic dosing. This is largely due to the hook effect resulting from saturating PROTAC molecules. Here, we present our work on finding ways to activate E3 ligases, which should improve the efficiency of a PROTAC. Improving efficiency will decrease the effective dose of a PROTAC and help avoid saturating doses in the clinic.

13:45 Cullin-RING連接酶組成的可塑性提高對分解藥的感受性

Cristina Mayor-Ruiz, Postdoctoral Fellow, Laboratory of Dr. Georg Winter, CeMM Research Center for Molecular Medicine, Austrian Academy of Sciences

We set out to systematically delineate all cellular effectors required for targeted protein degradation (TPD). We found that sensitivity to degraders is mainly dictated by shared modulator networks, with some exciting, ligase-specific differences. Perturbation of these effectors impairs cullin-RING ligase (CRL) plasticity and arrests many of them in a constitutively active state. Collectively, our study informs on regulation of CRLs amenable for TPD, and outlines biomarkers and putative resistance mechanisms for upcoming clinical investigation.

14:15 Mechanistic Modelling of PROTACs

Andreas Hock, PhD, Associate Principal Scientist, Discovery Sciences, AstraZeneca

PROTAC assisted protein degradation is affected by several cellular factors (concentration of target and E3, native turnover rate of target) as well as PROTAC dependent parameters (affinity to target, ligase, ternary complex formation and the rate of ubiquitin transfer). I will present the latest insights into which parameters are critical to understand for the PROTAC mode of action, enable efficacy prediction and how this can be applied to PROTAC optimisation.
