Application

Thio-NADP has been identified as a compound unique to the β-arrestin CNR2 screening assay4.

Biochem/physiol Actions

Studies using sea-urchin egg homogenates have reported that thio-NADP stimulates partial Ca2+ release at 50 μm and blocks successive challenge with a saturating concentration of nicotinic acid adenine dinucleotide phosphate (NAADP). Subsequent HPLC purification analysis have reported that Ca2+ release function of thio-NADP is because of the presence of NAADP as a contaminant. Hence, this study challenges the NAADP antagonist functions of thio-NADP and indicates that thio-NADP does not function as an NAADP blocker5.
Blocks nicotinate adenine dinucleotide phosphate (NAADP)-induced Ca2+ release

Analog of NADP

Preparation Note

Thionicotinamide adenine dinucleotidephosphate (thio-NADP) sodium is soluble in water at 50 mg/ml and yields a clear, yellow to dark yellow solution.

Nicotinic acid adenine dinucleotide phosphate (NAADP) is a metabolite of NADP, which can release Ca2+ from stores that are distinct from those activated by either cyclic ADP-ribose or inositol 1,4,5-trisphosphate (IP3). It has previously been suggested that thio-NADP is a
