Description
Thionicotinamide adenine dinucleotide is an analog of NAD. Use of Thio-NAD instead of NAD as a substrate for NAD(+)-consuming enzymes is more advantageous since the reduced form of Thio-NAD exhibits a substantial increase in absorbance at 405 nM, the most commonly available wavelength on microplate readers.
Chemical Properties
Light yellow powder
Uses
Thionicotinamide adenine dinucleotide has been used as a substrate analog in S-adenosyl-l-homocysteine (AdoHcy) hydrolases (SAHH) inhibition assay and in NAD+ glycohydrolase activity.
Application
Thionicotinamide adenine dinucleotide (thio-NAD) is a NAD derivative used in the determination of Carnitine by an enzymic cycling method with carnitine dehydrogenase.
Biochem/physiol Actions
Thionicotinamide adenine dinucleotide (sNAD) is an analog of coenzyme nicotinamide adenine dinucleotide (NAD) and NADH. sNAD is a potential inhibitor of NAD+ kinase. NAD+ kinase modulates NAD levels, contributing to cytotoxicity in cancer cells.
