Pemetrexed Disodium Hydrate (LY-231514; HSDB-7316; trade name Alimta), the hydrated disodium salt of Pemetrexed which is a synthetic pyrimidine-based antifolate, is a novel antifolate and antimetabolite anticancer drug targeting TS, DHFR and GARFT with Ki of 1.3 nM, 7.2 nM and 65 nM, respectively. Pemetrexed exhibits high autitumor activity in a broad range of tumors such as NSCLC/non-small cell lung carcinoma, malignant mesothelioma, and carcinomas of the breast, colorectum, uterine cervix, head and neck, and bladder.
| ln Vitro |
Pemetrexed (LY231514) disodium neoplasm is a novel family of classical antifolate medications whose anti-activity may result from its polyglutamate promoter's simultaneous and cooperative suppression of multiple essential folate enzyme needs. One of the most well-known enzyme FPGS substrates is pemetrexed (LY231514), with a Km of 1.6 μM and a Vmax/Km of 621. The selectivity and antitumor efficaciousness of LY231514 may be determined by its polyglutamate and polyglutamic acid auxiliaries. Although TS is inhibited by LY23l5l4 alone (Ki=340 nM in recombinant mice), LY23l5l4's glutamic acidity is strong. One of the most potent folic acid TS is LY231514, which is 100 times higher (Ki=3.4 nM) [1].

| ln Vivo |
Statistically speaking, the mice in the PC61 plus pemetrexed group survived longer than the other groups. According to survival analysis, mice treated with PC61 with pemetrexed had a considerably higher survival rate than mice treated with PC61 alone, rat IgG plus pemetrexed, or no therapy at all [2].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
