Tschimganine has different targets for chronological lifespan extension and growth inhibition in fission yeast

Abstract

Tschimganine inhibits growth and extends the chronological lifespan in Schizosaccharomyces pombe. We synthesized a Tschimganine analog, Mochimganine, which extends the lifespan similar to Tschimganine but exhibits a significantly weaker growth inhibition effect. Based on the comparative analysis of these compounds, we propose that Tschimganine has at least 2 targets: one extends the lifespan and the other inhibits growth.

Keywords: Mochimganine; Tschimganine; chronological lifespan; fission yeast.
