title: Comparisons of heptaminol AMP amidate and dibutyryl cyclic AMP on murine splenocytes proliferation.
abstract: Hepataminol AMP amidate (HAA), a nucleotide derivative possessing immunopotentiating activities, inhibited the mitogen-induced proliferation of murine splenocytes in vitro at the higher concentrations. Concanavalin A-induced mitogenic response was inhibited to 65 and 15% of the control value by HAA at the concentrations of 10(-4) and 10(-3) M, respectively. HAA also inhibited phytohemagglutinin P and lipopolysaccharide-induced responses at the same concentrations. The pattern of inhibition of mitogen-induced responses by HAA at higher concentrations was found to be almost similar to that of dibutyryl cyclic AMP (DbcAMP). Both HAA and DbcAMP also inhibited the blastogenesis of spleen cells in one way mixed lymphocyte reaction.
