Description: Pemetrexed (LY-231514; LY231514; HSDB7316; HSDB-7316; trade name Alimta), a synthetic pyrimidine-based antifolate, is antimetabolite anticancer drug that inhibits TS, DHFR and GARFT with Ki of 1.3 nM, 7.2 nM and 65 nM, respectively.

ProtocolIn VitroPemetrexed (LY231514) disodium is a novel classical antifolate, the antitumor activity of which may result from simultaneous and multipie inhibition of several key folate-requiring enzymes via its polyglutamated metabolites. Pemetrexed (LY231514) is one of the best substrates that is known for the enzyme FPGS (Km=1.6 μM and Vmax/Km=621). It is likely that polyglutamation and the polyglutamated metabolites of LY231514 play profound roles in determining both the selectivity and the antitumor activity of this novel agent. Whereas LY23l5l4 only moderately inhibits TS (Ki=340 nM, recombinant mouse), the pentaglutamate of LY23l5l4 is 100-fold more potent (Ki=3.4 nM), making LY231514 one of the most potent folate-based TS inhibitors.
