Human platelets incubated for 1 hr at 37° with nicotinic acid-7-14C (10 micromoles) accumulated the radioactivity with a gradient, (dpm per ml intraplatelet water)/(dpm per ml incubation medium), of approx. 20. The uptake process involved incorporation of the isotope into compounds such as NAD which do not readily diffuse from the cell. Of the total radioactivity inside, nicotinic acid represented approx. 3.9%, nicotinamide, 2.6%; NAD, 17.7%; and other products, 75.8%. Such synthesis and accumulation of radioactivity was variously inhibited by a number of analogs of nicotinic acid as well as by dinitrophenol, NaF, salicylate, and NaCN. Of the analogs studied, 2-hydroxynicotinic acid was the most potent. It reduced the gradient of radioactivity to 1.4 at 1mM and inhibited isotopic incorporation into the compounds previously described. These data suggest that 2-hydroxynicotinic acid inhibits one or more of the early reactions in the biosynthesis of NAD and nicotinamide. Nicotinamide-7-14C was neither accumulated nor metabolized by the platelet.
