A-3190
A-3190 is an orally active, blood-brain barrier permeable CD38 inhibitor, with an IC50 of 7.25 nM against human CD38 and 1.24 nM against mouse CD38. A-3190 is a derivative of A-8531 (HY-184021), and it forms covalent adducts with NAD+ in the presence of CD38. A-3190 acts as an inducer of NAD+ levels and an inhibitor of NAM and ADPR levels. A-3190 increases NAD+ levels in the skin, lung, liver and brain of rodents, while reducing NAM and ADPR levels in brain tissues. A-3190 can be used in research related to multiple sclerosis, Parkinson's disease and Alzheimer's disease.

Biological Activity
A-3190 (30 mg/kg; p.o.; single dose) maintains unbound plasma concentrations above the mouse CD38 IC50 for over 24 hours and achieves moderate brain penetration[1].

Result:Increased NAD+ levels in a dose-dependent manner in skin, lung, liver, and brain.
Significantly increased NAD+ levels relative to vehicle at 3, 10, and 30 mg/kg in skin, lung; at 1, 3, 10, and 30 mg/kg in liver and brain.
Reached unbound tissue concentrations up to ~1000-fold over the mouse CD38 IC50 at 30 mg/kg in skin, lung, and liver.
Decreased nicotinamide (NAM) and adenosine diphosphate ribose (ADPR) levels in a dose-dependent manner in brain, with significant reductions relative to vehicle seen at 1, 3, 10, and 30 mg/kg.
Reached unbound brain concentrations up to ~80-fold over the mouse CD38 IC50 at 30 mg/kg.
