Our laboratory has not validated this product for use on human JAK. However, based on the provided citation, the inhibitor appears to demonstrate effective activity on human cells as well. The study titled "Anti-adult T‑cell leukemia/lymphoma activity of cerdulatinib, a dual SYK/JAK kinase inhibitor" published in Int J Oncol. 2018 Oct;53(4):1681-1690 (PMID: 30066853) supports this observation.

General description
A potent inhibitor of Janus Protein tyrosine Kinases (JAKs). Displays potent inhibitory activity against JAK1 (IC50 = 15 nM for murine JAK1), JAK2 IC50 = 1 nM), JAK3 (Ki = 5 nM), and Tyk2 (IC50 = 1 nM). It inhibits other kinases only at much higher concentrations. Also inhibits IL-2- and IL-4-dependent proliferation of CTLL cells and blocks the phosphorylation of STAT5.
Biochem/physiol Actions

Synthetic cytokine receptors can modulate cellular functions based on an artificial ligand to avoid off-target and/or unspecific effects. However, ligands that can modulate receptor activity so far have not been used clinically because of unknown toxicity and immunity against the

Interleukin (IL)-7 is an essential nonredundant cytokine, and throughout the lifespan of a T-cell signaling via the IL-7 receptor influences cell survival, proliferation and differentiation. It is therefore no surprise that expression of the IL-7 receptor alpha-chain (CD127) is tightly
