Emavusertib (CA-4948) Emavusertib (CA-4948) is a potent and orally bioavailable inhibitor of interleukin-1 receptor-associated kinase 4/FMS-like Tyrosine Kinase 3 (IRAK4/FLT3) with anti-tumor activity.

Targets

IRAK4 ; FLT3

In vitro

Emavusertib (CA-4948) is over 500-fold more selective for IRAK-4 compared to IRAK-1. Emavusertib (CA-4948) reduces TNF-α, IL-1β, IL-6 and IL-8 release from TLR-Stimulated THP-1 Cells with an IC50 <250 nM. Emavusertib (CA-4948) has antiproliferative activity due to inhibition of receptor-type tyrosine-protein kinase FLT3.

In vivo

Emavusertib (CA-4948) has anti-tumour activity in animal models including tumours containing MyD88 gene mutations.
