Bioorg Med Chem Lett. 2016 Dec 15;26(24):5947-5950. doi: 10.1016/j.bmcl.2016.10.087. Epub 2016 Nov 2.

Abstract

Spleen Tyrosine Kinase (SYK) is a non-receptor cytoplasmic tyrosine kinase that is primarily expressed in hematopoietic cells. SYK is a key mediator for a variety of inflammatory cells, including B cells, mast cells, macrophages and neutrophils and therefore, an attractive approach for treatment of both inflammatory diseases and oncology indications. Using in house co-crystal structure information, and structure-based drug design, we designed and optimized a novel series of heteroaromatic pyrrolidinone SYK inhibitors resulting in the selection of the development candidate TAK-659. TAK-659 is currently undergoing Phase I clinical trials for advanced solid tumor and lymphoma malignancies, a Phase Ib study in advanced solid tumors in combination with nivolumab, and PhIb/II trials for relapsed/refractory AML.

Keywords: Kinase inhibitor; Kinase selectivity; Leukemia; Lymphoma; SYK; Structure-based drug discovery.
