nf-56-ej40 hydrochloride

NF-56-EJ40 hydrochloride is a potent, high-affinity, and highly selective human SUCNR1 (GPR91) antagonist with an IC50 of 25 nM and a Ki of 33 nM, and shows almost no activity towards rat SUCNR1. NF-56-EJ40 hydrochloride has high affinity for humanized rat SUCNR1 with a Ki value of 17.4 nM.

Taltobulin hydrochloride is a synthetic analogue of the tripeptide hemiasterlin, is a potent agent of antimicrotubule that circumvents P-glycoprotein-mediated resistance in vitro and in vivo.

YW3-56 is an inhibitor of protein arginine deiminase 2 (PAD2) and PAD4 (IC50s = 0.5-1 and 1-5 μM, respectively).1It inhibits the growth of U2OS osteosarcoma cells (IC50= ~2.5 μM) in a p53-dependent mannerviainduction of SESN2 and subsequent inhibition of mTORC1. YW3-56 (10 mg/kg) reduces tumor growth in an S-180 murine sarcoma tumor model. It also inhibits tumor growth in the 1883 MDA-MB-231 breast cancer bone metastasis mouse xenograft model.2 1.Wang, Y., Li, P., Wang, S., et al.Anticancer peptidylarginine deiminase (PAD) inhibitors regulate the autophagy flux and the mammalian target of rapamycin complex 1 activityThe Journal of Biological Chemisty287(31)25941-25952(2012) 2.Wang, S., Chen, X.A., Hu, J., et al.ATF4 gene network mediates cellular response to the anticancer PAD inhibitor YW3-56 in triple-negative breast cancer cellsMol.
