pralatrexate - Generic Medications

Pralatrexate is a dihydrofolate reductase inhibitor. Pralatrexate has the chemical name (2S)-2-[[4-[(1RS)-1-[(2, 4-diaminopteridin-6-yl)methyl]but-3- ynyl]benzoyl]amino]pentanedioic acid. The molecular formula is C 23 H 23 N 7 O 5 and the molecular weight is 477.48 g/mol. Pralatrexate is a 1:1 racemic mixture of S- and R- diastereomers at the C10 position (indicated with *). The structural formula is as follows: Pralatrexate is an off-white to yellow solid. It is soluble in aqueous solutions at pH 6.5 or higher. Pralatrexate is practically insoluble in chloroform and ethanol. The pKa values are 3.25, 4.76, and 6.17. FOLOTYN (pralatrexate) is supplied as a preservative-free, sterile, isotonic, non-pyrogenic clear yellow aqueous solution contained in a clear glass single-dose vial (Type I) for intravenous use. Each 1 mL of solution contains 20 mg of pralatrexate, sufficient sodium chloride to achieve an isotonic (280-300 mOsm) solution, and sufficient sodium hydroxide, and hydrochloric acid if needed, to adjust and maintain the pH at 7.5-8.5. FOLOTYN is supplied as either 20 mg (1 mL) or 40 mg (2 mL) single-dose vials at a concentration of 20 mg/mL. Structural Formula
