Final Agenda

7:30 am Registration Open and Morning Coffee

TARGETING THE CANCER ENVIRONMENT

8:15 Chairperson's Opening Remarks

Lijun Sun, PhD, Director, Center for Drug Discovery and Translational Research, Beth Israel Deaconess Medical Center, Harvard Medical School

8:20 Challenges in Phenotypic, Target Agnostic Drug Discovery: Lessons Learned from a Cell-Based Screen Designed to Identify Small Molecules that Decrease C-MYC in Cancer Cells

Jesus Medina, PhD, Manager, Medicinal Chemistry, GlaxoSmithKline

One of the key challenges in cell-based phenotypic drug discovery efforts is the early assessment of the validity and viability of hits obtained from the screen. Using our c-MYC cellular screen as an example, we describe a strategy to determine whether the MOA of the hits has in vivo translatability. The details of our screening strategy/triage campaign, molecular target identification efforts, results from in vivo studies, and the lessons learned along the way will be discussed.

8:50 Rational Design of AKR1C3 Inhibitors as Chemotherapeutic Potentiators

Paul Trippier, PhD, Professor, Department of Pharmaceutical Sciences, Texas Tech University Health Sciences Center

Aldo-keto reductase 1C3 (AKR1C3) catalyzes the downstream conversion of androgen precursors to the potent androgen receptor ligands testosterone and 5α-dihydrotestosterone, and conversion of PGD2 to 11β-PGF2α and PGF2α prostanoids and hence acts as an important regulator of myeloid cell proliferation and differentiation. The enzyme is highly upregulated in prostate cancer and a number of leukemias. We have designed potent and highly selective inhibitors that act to potentiate clinical chemotherapeutics >200-fold. Such action results in reduced dosing, reduced toxic side effects and completely counters AKR1C3-mediated drug resistance. Our inhibitors provide a strategy for treating vulnerable patients diagnosed with these and other neoplasms in combination with existing chemotherapeutics

9:20 Discovery and Preclinical Characterization of GSK532, a Highly Efficacious STING Agonist for Immuno-Oncology

Yiqian Lian, PhD, Program Team Leader, Immuno-Oncology & Combinations DPU, GlaxoSmithKline

The cGAS-STING pathway plays a crucial role in body's spontaneous sensing of tumor by the immune system. Unlike checkpoint inhibitors that unleash the body's tumor immune response, STING agonists prime tumor immunity by initiating tumor antigen presentation and tumor specific T-cell response. Herein, we report the discovery of highly efficacious novel STING agonist GSK532 for application in immuno-oncology.

9:50 Grand Opening Coffee Break in the Exhibit Hall with Poster Viewing

SMALL MOLECULES FOR IMMUNONCOLOGY

10:35 Selective Inhibitors of CLK And DYRK Kinases and Their Anticancer

Lijun Sun, PhD, Director, Center for Drug Discovery and Translational Research, Beth Israel Deaconess Medical Center, Harvard Medical School

CDC2-like kinase (CLK) and dual specific tyrosine phosphorylation-regulated kinase (DYRK) control the mRNA splicing events via priming phosphorylation of key SF members of the spliceosome. CLK and DYRK are aberrantly activated in a number of cancers and are attractive targets for developing anticancer therapy. We describe our SAR results of a class of novel water-soluble benzimidazoles as selective CLK/DYRK inhibitors. In vitro activity in the NCI60 panel screen of the advanced lead candidates, as well as in vivo efficacy in established prostate cancer tumor models, will be presented.

11:05 Modulation of Innate B1 Lymphocyte Immune Response in Cancer

Nikolai Tupitsyn, PhD, Professor, Cancer Immunology, Lab, Blokhin Cancer Research Center

B1 natural pentameric immunoglobulins can destroy cancer cells. This is selective process usually being directed against tumor associated glycans not expressed by normal cells. Monoclonal antibodies to tumor associated glycan proved their efficacy in gastric cancer. Is there any possibility to use immunoadjuvants to elevate natural B1 immunity to effective level?

KINASE INHIBITORS FOR CANCER

1:15 Chairperson's Remarks

Neil Grimster, Senior Scientist, Oncology Chemistry, AstraZeneca

1:20 Discovery and Optimization of a Novel Series of Highly Selective JAK1 Kinase Inhibitors

Neil Grimster, Senior Scientist, Oncology Chemistry, AstraZeneca

Janus kinases (JAKs) have been demonstrated to be critical in cytokine signaling, and have thus been implicated in both cancer and inflammatory diseases. The development of small molecule inhibitors that are selective for a specific family member would represent highly desirable tools for deconvoluting the intricacies of JAK family biology. Here we present the discovery of a potent and orally bioavailable JAK1 inhibitor, which possess ~1000 fold selectivity over the other highly homologous JAK family members, and good selectivity over kinases in general.

1:50 Optimization of Kinact Delivers a First in Class Specific Covalent JAK3 inhibitor PF-06651600

Atli Thorarensen, PhD, Research Fellow, BioTc Medicinal Chemistry, Pfizer

2:20 Sponsored Presentation (Opportunity Available)

2:50 Refreshment Break in the Exhibit Hall with Poster Viewing

3:30 A Kinase Inhibitor for a Chronic Indication: A Case Study in Balancing Selectivity and Safety to Advance Potent, Selective and Orally Bioavailable MAP4K4 Leads to Preclinical Toxicity Studies

Samit Bhattacharya, PhD, Senior Principal Scientist, World Wide Medicinal Chemistry, Pfizer

This presentation will describe the identification of an aminopyridine lead series from virtual screening and evolution of multiple aminopyridine leads that led to discovery of advanced potent, selective and orally bioavailable MAP4K4 inhibitors. Given the concerns of chronic safety for a kinase inhibitor in a non-oncology indication, this presentation will discuss strategies that were employed to advance two chemotypes (PF-06279789 and PF-06745013) with excellent kinase selectivity but orthogonal profiles to assess safety of the mechanism.

8:30 Kinetic and Thermodynamic Profiling in Drug Discovery: A Case Study with EED Hit-to-Lead Program

Ying Wang, PhD, Principal Scientist, Department of Chemistry & Technology, AbbVie

Our analysis revealed for the first time that ITC data should be interpreted in the context of chiral purity of the compounds. The thermodynamic signatures of the EED amino pyrrolidine compounds were found to be mainly enthalpy driven with improved enthalpic contributions as the program progressed. We will also present our perspectives on where we are at on harnessing the power of thermodynamic and kinetic profiling in drug discovery.
