IC50: 790 nM for canonical Wnt signaling
JW 74 is an inhibitor of the catalytic PARP domain of TNKS1/2.
Wnt/β-catenin, a major regulator of stem cell self-renewal and differentiation, is aberrantly activated in a several cancers, including osteosarcoma. Thus, attenuation of Wnt/β-catenin activity by tankyrase inhibitors is an appealing strategy in osteosarcoma treatment.
In vitro: Previous study found that JW74 at the molecular level induced stabilization of AXIN2, a key component of the β-catenin destruction complex, leading to reduced levels of nuclear β-catenin. In addition, JW74 could induce reduced cell growth in all tested cell lines, partially due to a delay in cell cycle progression and partially because of an induction of caspase-3-mediated apoptosis. Moreover, JW74 was able to induce the differentiation in U2OS cells and also enhance differentiation of OS cell lines that did not harbor a differentiation block .
In vivo: Previous animal study found that the dose of 150 mg/kg of JW74 in ApcMin model could reduce the small intestinal adenoma by 48% and was comparable with celecoxib or rofecoxib. Furthermore, it was noteworthy that JW74 became rapidly cleared from the blood stream due to its poor in vivo stability .
Clinical trial: Up to now, JW 74 is still in the preclinical development stage.
