Shields J, Baker D, Balazs A, Bommakanti G, Casella R, Cao S, et al.
J Med Chem . 2025 Feb; 68(4):4582-4595. PMID: 39928839
Hematopoietic progenitor kinase 1 (HPK1) is a negative regulator of the T cell receptor signaling pathway and is therefore a target of interest for immunooncology. Nonselective HPK1 inhibitors may affect...

J Med Chem . 2025 Jan; 68(3):3700-3748. PMID: 39869768
Despite recent advances in the inhibition of EGFR (epidermal growth factor receptor), there remains a clinical need for new EGFR Exon20 insertion (Ex20Ins) inhibitors that spare EGFR WT. Herein, we...

Scott J, Moss T, Barlaam B, Davey P, Fairley G, Gangl E, et al.
ACS Med Chem Lett . 2020 Dec; 11(12):2519-2525. PMID: 33335676
Herein we describe our efforts using a late stage functionalization together with more traditional synthetic approaches to generate fluorinated analogues of the clinical candidate AZD9833. The effects of the addition...
