キナーゼ阻害剤の創薬と設計に対する新たなアプローチ

2018年4月3-4日 | Hilton Bayfront | カリフォルニア州サンディエゴ

 

過去10年間のキナーゼ阻害剤の創薬に向けた取り組みからは、新世代の抗がん剤が短期間で開発されるといった成果が生まれています。現在も開発に向けた作業が活発に行われているキナーゼ阻害剤は、創薬の分野で重要な位置を占めており、ヒトキノームの標的領域のより深い部分へと活動を拡げるための新たな方法の発見、がんのみならず、中枢神経系疾患といった慢性疾患に対応する医薬品の開発、アロステリック調節への重点の移行、滞留時間の長い化合物や不可逆性化合物の利用といった分野で成果が生まれています。

キナーゼ阻害剤の化学をテーマにしたこのカンファレンスプログラムでは、大学や製薬会社で指導的な役割を担っている研究者が一堂に会し、人脈や協力関係を構築しながら、キナーゼ阻害剤創薬分野における研究の進捗状況について意見を交換します。

8:10 FEATURED PRESENTATION: Selective Targeting of Kinase Catalytic and Non-Catalytic Function

Stefan Knapp, PhD, Professor, Department of Pharmaceutical Chemistry, Goethe Institut, Frankfurt

Advances in kinase structural biology led to an excellent structural coverage of the human kinase family and provided insight into the remarkable domain plasticity of the catalytic domain. Our laboratory contributed 75 of the currently ~200 known crystal structures, enabling a family-wide structural analysis for rational design of inhibitors. In this talk I will summarize strategies that led to the development of highly selective inhibitors. I will discuss the discovery of novel inhibitor binding sites including allosteric sites and the exploitation of unusual structural features for the design of highly selective kinase inhibitors.

8:40 Structure-Based Design of Long Residence Time into Novel Kinase Inhibitors

Gerhard_MuellerGerhard Mueller, PhD, CSO, Gotham Therapeutics

The presentation focuses on the engineering of binding kinetic signatures into "deep-pocket-directed" scaffolds for achieving high-efficacy kinase inhibitors. We will demonstrate that a thorough understanding of the precise pharmacophoric requirements on the target's binding site is essential to pre-engineer the desired slow off-rates into new, thus literature-unprecedented scaffolds that qualify as privileged structures for the target family of kinases.

9:40 Coffee Break

10:05 Target Residence Time-Guided Optimization of TTK Kinase Inhibitors

Guido_ZamanGuido J.R. Zaman, PhD, Managing Director & Head of Biology, Netherlands Translational Research Center B.V. (NTRC)

We studied NTRC 0066-0, a selective inhibitor of TTK, together with eleven TTK inhibitors from different chemical classes developed by others. Parallel testing showed that the cellular activity of the TTK inhibitors correlates with their binding affinity and, more strongly, with target residence time. X-ray structures revealed that the most potent inhibitors induce a unique structural conformation. Based on this insight, new TTK inhibitors were developed with longer target residence times and very potent anti-proliferative activity.

10:35 Comparison of Methods for Determination of Drug-Target Engagement in Live Cells

Aleksandra_BaranczakAleksandra Baranczak, PhD, Senior Scientist, Discovery Chemistry and Technology, AbbVie

While the list of potential techniques that enable studies of target engagement is continuously expanding, identification of the best method to evaluate interactions between a ligand and its cellular binding partner(s) remains far from straightforward. We will discuss the applicability of various methods for determining target engagement of reversible and irreversible inhibitors of soluble and membrane kinases in live cells. The strengths and limitations of all methods will be analyzed, as well as their adaptability to high-throughput format assay development.

11:05 Determination of a Focused Mini-Kinase Panel for Early Identification of Selective Kinase Inhibitors

Scott_BembenekScott Bembenek, PhD, Principal Scientist, Computer-Aided Drug Discovery, Janssen Research & Development

Currently, a rational, systematic, and unbiased method for choosing such a mini-kinase panel that reliably determines a compound's kinase selectivity profile does not exist. Using a novel in-house deconvolution algorithm, we performed a comprehensive analysis on our extensive kinase data set that has yielded findings far beyond those in the current literature. Indeed, one can construct a mini-kinase panel of optimal size that is very predictive when compared to the corresponding full kinase panel. Comparing this mini-kinase panel to random selection, we find an enrichment of 45.1%.

1:20 Highly Selective JAK3-Inhibitors with a Covalent-Reversible Binding Mode Targeting a Nitrile-Induced Arginine Pocket

Stefan_LauferStefan Laufer, PhD, Chairman, Pharmaceutical & Medicinal Chemistry, Pharmacy & Biochemistry, University of Tuebingen

JAK3 functions are restricted to immune cells, suggesting it as a primary target. However, the high degree of structural conservation makes isoform selective targeting a challenging task. Here we present picomolar inhibitors with unprecedented selectivity for JAK3. Selectivity was achieved by concurrent covalent-reversible targeting of a JAK3-specific cysteine residue and a novel induced binding pocket yielding versatile tool compounds for the elucidation of JAK3 specific functions.

1:50 The Meisenheimer Complex as a Novel Paradigm in Drug Discovery: Targeting PLK1 through a Novel Covalent Mechanism

Campbell_MclnnesCampbell McInnes, PhD, Professor, Drug Discovery and Biomedical Sciences, University of South Carolina

We will describe novel inhibitors of PLK1 kinase activity that inhibit through a unique covalent strategy. The discovery and optimization of these inhibitors is described in addition to confirmation of their on-target anti-tumor mode of action through selective PLK1 inhibition.

2:20 Presentation to be Announced


2:50 FEATURED PRESENTATION: Discovery of the Covalent FGFR1-4 Inhibitor PRN1371 for the Treatment of Solid Tumors

Michael Bradshaw, PhD, Associate Director, Principia Biopharma

We have developed a selective, irreversible covalent inhibitor of FGFR1-4, PRN1371, by targeting a cysteine residue within the kinase domain. PRN1371 demonstrates highly selective and long lasting inhibition of FGFR which extends beyond drug clearance from circulation. Strong inhibition was also sustained toward clinically relevant FGFR mutations and translocations. In addition, durable tumor regression was obtained in multiple rodent xenograft models and was sustained even using an intermittent dosing strategy that provided drug holidays. PRN1371 is currently in a Phase I clinical trial for the treatment of solid tumors.

4:40 PLENARY KEYNOTE: Targeting Ras and MYC for the Treatment of Cancer

Stephen Fesik, PhD, Professor of Biochemistry, Pharmacology, and Chemistry, Orrin H. Ingram II Chair in Cancer Research, Vanderbilt University School of Medicine

Two of the most important targets in cancer are Ras and MYC. However, both of these highly validated cancer targets are thought to be undruggable. In this presentation, I will discuss our approaches for targeting both of these proteins directly and indirectly using fragment-based methods and structure-based design.

9:05 Isoform-Selective Activators of AMP-Activated Protein Kinase for Metabolic Diseases

Ravi_KurumbailRavi G. Kurumbail, PhD, Research Fellow and Structural Biology Laboratory Head, Pfizer

AMP-activated protein kinase (AMPK) is a heterotrimeric protein kinase that maintains cellular and whole-body energy homeostasis. We have been seeking specific activators of AMPK for the treatment of cardiovascular and metabolic diseases. High-throughput screening using a novel biochemical assay platform resulted in the identification of multiple chemotypes that target distinct AMPK subunits. We have established the molecular mode of action of these isoform-selective activators through structural, biophysical and kinetic studies.

10:30 Optimization of Brain Penetrant ATM Kinase Inhibitors for the Treatment of Huntington's Disease

Leticia_Toledo-ShermanLeticia Toledo-Sherman, PhD, Director of Computer-Aided Drug Design and Medicinal Chemistry, Chemistry, CHDI Foundation

The presentation will be centered on our efforts to attain potent, selective and brain penetrant ATM kinase inhibitors as proof-of-concept agents for HD. Importantly we demonstrate strong in vitro-in vivo correlations and a robust PK/PD relationship that warrant further studies with these compounds.

Masato Yoshikawa, PhD, Principal Scientist, CNS Drug Discovery Unit, Research, Takeda Pharmaceutical Company Limited

We will present a discovery of 7-oxo-2,4,5,7-tetrahydro-6H-pyrazolo[3,4-c]pyridine derivatives as a novel chemical series of brain-penetrating RIP1 kinase inhibitors. The optimization by utilizing SBDD approach led to the discovery of a highly potent, orally active, and brain-penetrating RIP1 kinase inhibitor with excellent PK profiles. Our preclinical candidate significantly suppressed necroptotic cell death both in mouse and human cells. Oral administration of the candidate (10 mg/kg, bid) attenuated disease progression in the mouse EAE model of multiple sclerosis.
