Uses

Pemoline magnesium (18968-99-5)can enhancement of Brain RNA Polymerases: The stimulation by magnesium pemoline of systems that synthesize brain nucleic acid was studied in vivo and in vitro. There are differential effects between true RNA polymerase and pseudo-RNA polymerase. The selective stimulation of true RNA polymerase by magnesium pemoline was not observed with stimulants of the central nervous system and psychotropic agents.
