Osunprotafib hydrochloride

(Synonyms: ABBV-CLS-484 hydrochloride)

Osunprotafib (ABBV-CLS-484) hydrochloride is an orally active and selective active site PTPN1 (IC₅₀: 2.5 nM) and PTPN2(IC₅₀: 1.8 nM) inhibitor. Osunprotafib hydrochloride has 6-8-fold weaker activity on PTPN9 and no detectable activity on SHP-1 or SHP-2. Osunprotafib hydrochloride increases the sensitivity of human cancer cell lines to IFNγ. Osunprotafib hydrochloride generates robust anti-tumor immunity by enhancing JAK-STAT signalling and reducing T cell dysfunction.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
