cd38-in-78c cd38-in-78c cd38-in-78c is a drug which acts as a potent and selective inhibitor of the glycoprotein enzyme cd38. in animal studies it boosts levels of nicotinamide adenine dinucleotide (nad+) in tissues via inhibition of cd38 mediated breakdown of nicotinamide riboside (nr) and nicotinamide mononucleotide (nmn), and has been shown to ameliorate metabolic dysfunction associated with the aging process. it also has potential therapeutic application in the treatment of asthma. cd38-in-78cidentifiers iupac name 4--1-methyl-6-(1,3-thiazol-5-yl)quinolin-2-one cas number1700637-55-3pubchem cid118736856chemical and physical dataformulac22h27n3o3smolar mass413.54 g·mol−13d model (jsmol)interactive image smiles cn1c2=c(c=c(c=c2)c3=cn=cs3)c(=cc1=o)nc4ccc(cc4)occoc inchi inchi=1s/c22h27n3o3s/c1-25-20-8-3-15(21-13-23-14-29-21)11-18(20)19(12-22(25)26)24-16-4-6-17(7-5-16)28-10-9-27-2/h3,8,11-14,16-17,24h,4-7,9-10h2,1-2h3key:vjqalsobhvejqm-uhfffaoysa-n
