Abstract

Leishmania donovani S-adenosyl-L -methionine (AdoMet) decarboxylase was found to show a growth related pattern. Methylglyoxal bis (guanylhydrazone) (MGBG) and Berenil inhibited the growth of Leishmania donovani promastigotes (strain UR6) in a dose dependent manner. The concentrations of MGBG and Berenil required for 50% inhibition of rate of growth were 67 and 47 µM, respectively. The growth inhibition of MGBG was partially reversed by spermidine (100 µM) and spermine (100 µM). Berenil inhibition of promastigote growth was partially reversed by 100 µM spermidine whereas 100 µM spermine did not result in any reversal of growth. The reduction in parasitemia in vitro by these inhibitors was accompanied by inhibition of AdoMet decarboxylase activity and spermidine levels.
