Information about this agent

Imetelstat sodium is the sodium salt of imetelstat, a synthetic lipid-conjugated, 13-mer oligonucleotide N3' P5'-thio-phosphoramidate with potential antineoplastic activity. Complementary to the template region of telomerase RNA (hTR), imetelstat acts as a competitive enzyme inhibitor that binds and blocks the active site of the enzyme (a "telomerase template antagonist"), a mechanism of action which differs from that for the antisense oligonucleotide-mediated inhibition of telomerase activity through telomerase mRNA binding. Inhibition of telomerase activity in tumor cells by imetelstat results in telomere shortening, which leads to cell cycle arrest or apoptosis. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).
