Imetelstat
Based on 1 Customer Validation
Imetelstat (GRN163L) is a 13-mer oligonucleotide and competitive Telomerase inhibitor. Imetelstat binds with high affinity to the template region of the RNA component of human telomerase. Imetelstat induces Apoptosis. Imetelstat is capable of selectively eliminating myelofibrosis hematopoietic stem cells. Imetelstat leads to the loss of a cancer cell's ability to maintain telomere length, resulting in the inhibition of cell proliferation.

Biological Activity
Imetelstat is a telomerase inhibitor that leads to the loss of a cancer cell's ability to maintain telomere length, resulting in the inhibition of cell proliferation[1].
Imetelstat (1.8-7.5 μM; 2-7 d) inhibits proliferation of primary myelofibrosis CD34+ cells, induces apoptosis but has no significant effect on normal cord blood CD34+ cells[2].

Animal Model:NOD/SCID/IL2Rgnull (NSG) (8- to 9-week-old; sublethally irradiated)[2]
-
Dosage:5 mg/kg; 15 mg/kg; 30 mg/kg
-
Administration:i.p.; 3 times weekly; 4 weeks or 8 weeks
-
Result:Resulted in a 15.4% reduction in the number of hCD34+ cells at 15 mg/kg for 8 weeks.\nDid not result in a greater reduction in hCD45+ or hCD34+ cells at 30 mg/kg for 8 weeks.
