L-alanosine
An amino acid analogue and antibiotic derived from the bacterium Streptomyces alanosinicus with antimetabolite and potential antineoplastic activities. L-alanosine inhibits adenylosuccinate synthetase, which converts inosine monophospate (IMP) into adenylosuccinate, an intermediate in purine metabolism. L-alanosine-induced disruption of de novo purine biosynthesis is potentiated by methylthioadenosine phosphorylase (MTAP) deficiency. The clinical use of this agent may be limited by its toxicity profile. MTAP is a key enzyme in the adenine and methionine salvage pathways. Check for active clinical trials using this agent.
