Biochem/physiol Actions

NCT-501 is a potent and selective inhibitor of Aldehyde dehydrogenase ALDH1A1, a dehydrogenase that has been found to be elevated in certain cancers and in cancer stem cells. NCT-501 had an IC50 value of 40 nM and was found to be 1000-fold selective for ALDH1A1 over other ALDH enzymes and other dehydrogenases. NCT-501 treatment of head and neck squamous-cell carcinoma (HNSCC) explants in combination with cisplatin resulted in a significant decrease in proliferating cells.

We studied whether the accumulation of advanced lipoxidation end-products (ALEs) in the diabetic retina is linked to the impairment of lipid aldehyde detoxification mechanisms. Retinas were collected from nondiabetic and diabetic rats and processed for conventional and quantitative RT-PCR (qRT-PCR)

Aldehyde dehydrogenases (ALDHs) metabolize reactive aldehydes and possess important physiological and toxicological functions in areas such as CNS, metabolic disorders, and cancers. Increased ALDH (e.g., ALDH1A1) gene expression and catalytic activity are vital biomarkers in a number of malignancies and
