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.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
