A new cyclitol derivative influences inositol metabolism in Neurospora crassa
1Department of Biology, University Medical School, Debrecen, Hungary.
Abstract:
Cyclitol derivatives have been synthesized and screened for growth inhibitory effect upon prokaryotic and eukaryotic organisms. One derivative, (2S,3R,5R)-3-azido-2-benzoyloxy-5-hydroxycyclohexanone, was studied in detail: it has no effect upon bacteria, but it is inhibitory to Neurospora crassa. In Neurospora crassa it increased the amount of myo-inositol-1-phosphate synthase and inhibited the activity of myo-inositol-monophosphatase. The enhanced synthesis of myo-inositol-1-phosphate synthase was the consequence of lowering the intracellular inositol concentration. Li+ treatment of Neurospora crassa has effects similar to those of P.I.-658.
