In Vitro

JAK3-IN-13 (compound 12n) (10 μM; 72 h) shows antiproliferative activity in BaF3-JAK3M511I, U937, parental cells[1].
JAK3-IN-13 inhibits the activity of TEL-JNK1, TEL-JNK2, JNK3M511I, JNK3 with IC50 values of 177.7, 134.2, 22.9, 1.2 nM, respectively[1].
JAK3-IN-13 inhibits (0-800 nM; 0-24 h) decreases the expression of phosphorylation JAK3, STAT3, and STAT5 in a dose-dependent manner[1].
JAK3-IN-13 inhibits (0-330 nM; 24 h) induces cell cycle arrest at G0/G1 phase and down-regulates the expression of cyclin-dependent kinase 2 (CDK2), CDK4, CDK6, cyclin B1, cyclin D3, and cyclin E1 in a concentration-dependent manner[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
