Description: NCT-505 is an Orally Bioavailable aldehyde Dehydrogenase 1A1 (ALDH1A1) Inhibitor with Potent Cellular Activity (IC50 = 7 nM). NCT-505 demonstrated target engagement in a cellular thermal shift assay (CETSA), inhibited the formation of 3D spheroid cultures of OV-90 cancer cells, and potentiated the cytotoxicity of paclitaxel in SKOV-3-TR, a paclitaxel resistant ovarian cancer cell line. NCT-505 also exhibit high specificity over other ALDH isozymes and unrelated dehydrogenases.

Additional Information

Aldehyde dehydrogenases (ALDHs) are responsible for the metabolism of aldehydes (exogenous and endogenous) and possess vital physiological and toxicological functions in areas such as CNS, inflammation, metabolic disorders, and cancers. Overexpression of certain ALDHs (e.g., ALDH1A1) is an important biomarker in cancers and cancer stem cells (CSCs) indicating the potential need for the identification and development of small molecule ALDH inhibitors.
