MedKoo Cat#: 201452 | Name: GS-9219

Description:

WARNING: This product is for research use only, not for human or veterinary use.

GS-9219 is a prodrug of the acyclic nucleoside phosphonate analogue 9-(2-phosphonylmethoxyethyl)guanine (PMEG) with potential antineoplastic activity. Formulated to selectively accumulate in lymphocytes, nucleotide analogue GS 9219 is converted to its active metabolite, PMEG diphosphate (PMEGpp), via enzymatic hydrolysis, deamination, and phosphorylation; subsequently, PMEGpp is incorporated into nascent DNA chains by DNA polymerases, which may result in the termination of DNA synthesis, S-phase cell cycle arrest, and the induction of apoptosis in susceptible lymphoma cell populations.

More Info
GS-9219 was designed as a cytotoxic agent that preferentially targets lymphoid cells.  In lymphocytes, GS-9219 is converted to its active metabolite, PMEG diphosphate, via enzymic hydrolysis, deamination, and phosphorylation. GS-9219 has substantial antiproliferative activity against activated lymphocytes and hematopoietic tumor cell lines. In contrast, resting lymphocytes and solid tumor lines were less sensitive to GS-9219. GS-9219, but not PMEG, depleted the germinal centers in lymphoid tissues of normal beagle dogs at doses that were tolerated. In addn., GS-9219 displayed significant in vivo efficacy in five dogs with spontaneous NHL after a single administration, with either no or low-grade adverse events.  GS-9219 may have utility for the treatment of NHL.
