GRN163L is a thio- phosphoramidate oligonucleotide, a class of synthetic nucleic acid that has a number of potential advantages over earlier-generation synthetic nucleic acid chemistries, including enhanced sequence-specific DNA and RNA binding activity, high resistance to degradation, and improved uptake and biodistribution properties.
announced today that it has agreed to provide an additional supply of modified nucleic acid building block compounds to Geron Corporation for use in the synthesis of one of Geron's novel thio- phosphoramidate-based telomerase inhibitor anti-cancer drugs, GRN163L (formerly named GRN719).
