Bioactivity	SJ988497 is a PROTAC JAK2 degrader. SJ988497 potently inhibits CRLF2-rearranged (CRLF2r) cell proliferation and degrades the CRBN neosubstrate GSPT1. SJ988497 consists of a Ruxolitinib (HY-50856) derivative, linker, and CRBN ligand Pomalidomide. SJ988497 can be used in the research of acute lymphoblastic leukemia (ALL)[1].
Invitro	SJ988497 (compound 7) increases cell permeability in the Caco-2 assay, with the apparent permeability coefficient (Papp) of 19.12 nm/s[1].SJ988497 inhibits parental MHH-CALL-4 cells with an EC50 of 0.4 nM, inhibits CRBN-KD MHH–CALL-4 cells with an EC50 of 3456.2 nM, and can be blocked by 30 μM Lenalidomide (HY-A0003)[1].SJ988497 (1 h, 1 μM) results in comparable JAK inhibition in MHH–CALL-4 cells[1]. Cell Viability Assay[1] Cell Line:
In Vivo	SJ988497 (compound 7) (30 mg/kg, i.p.) reduces spleen size and tumor burdens, and is well tolerated with no weight loss or perturbation in blood count[1].SJ988497 (10-100 mg/kg, i.p., twice daily) showed sustained in vivo exposure with the plasma concentration above the cellular 50% effective concentration value after 24 hour[1].
