Gusacitinib (ASN-002) is an orally active and potent dual inhibitor of spleen tyrosine kinase (SYK) and janus kinase (JAK) with IC₅₀ values of 5-46 nM. Gusacitinib has anti-cancer activity in both solid and hematological tumor types^[1].

IC50: 5-46 nM (SYK, JAK)^[1].

In mechanistic cell-based studies involving IgE and cytokine stimulations, Gusacitinib (ASN-002) strongly suppresses the SYK and JAK family kinase signaling pathways measured as pLAT and pSTAT levels, respectively. Gusacitinib (ASN-002) shows anti-proliferative activity in a broad panel of human cancer cell lines including DHL6, DHL4, OCI-LY10, H929, Pfeiffer, HT-1376, and Lovo, suggesting activity in both solid and hematological tumor types^[1].

In a multiple myeloma (H929) xenograft model, Gusacitinib (ASN-002) exhibits significant efficacy in inhibiting tumor growth (>95%). It also significantly delays the onset of hind limb paralysis in the human erythroleukemia (HEL) mouse model. Gusacitinib (ASN-002) has good oral bioavailability, metabolic stability, is not a Pgp substrate, and shows little to no inhibition of CYP450 isozymes. Gusacitinib (ASN-002) shows a favorable safety profile in rat and dog toxicology studies^[1].
