Overview

Information

ND646 ND-646 is an allosteric inhibitor of the ACC (Acetyl-coA carboxylase) enzymes that prevents ACC subunit dimerization to suppress fatty acid synthesis with IC50 of 3.5 nM and 4.1 nM for hACC1 and hACC2, respectively.


Targets

hACC1 (Cell-free assay); hACC2 (Cell-free assay) 3.5 nM; 4.1 nM


In vitro

ND-646 inhibits FASyn in vitro and induces apoptosis in NSCLC cells. AMPK phosphorylation sites can be used as a biomarker to monitor ACC engagement by ND-646.


In vivo

Chronic ND-646 treatment of xenograft and genetically engineered mouse models of NSCLC inhibits tumor growth. When administered as a single agent or in combination with the standard-of-care drug carboplatin, ND-646 markedly suppresses lung tumor growth in the Kras;Trp53−/− (also known as KRAS p53) and Kras;Stk11−/− (also known as KRAS Lkb1) mouse models of NSCLC.
