Methylthio-DADMe-immucillin-A (MT-DADMe-ImmA) is an 86-pm inhibitor of human 5-methylthioadenosine phosphorylase (MTAP). Treatment of cultured cells with MT-DADMe-ImmA and MTA inhibited MTAP, increased cellular MTA concentrations, decreased polyamines, and induced apoptosis in FaDu and Cal27, two head and neck squamous cell carcinoma cell lines.The selective action of MT-DADMe-ImmA on head and neck squamous cell carcinoma cells suggests potential as an agent for treatment of cancers sensitive to reduced CpG island methylation.
