- PROCESS FOR PREPARATION OF AN ANTIFOLATE AGENT
-
The specification relates to a process for preparation of an antifolate compound of formula 7, such as Pralatrexate. Also, disclosed are intermediates and processes for preparation of intermediates useful in the preparation of the antifolate compound. The substituents Y, Z, R, R1 and R2 are as described herein. The processes and intermediates can provide an alternate route to the synthesis of the antifolate compound. Further, the processes can help to avoid distillation or evaporation of high boiling point solvents, chromatographic purification and use of hazardous combination of solvents; and can also provide a product having high purity, all of which are desirable for synthesis on a large scale.

- Treatment of T-cell lymphoma using 10-propargyl-10-deazaaminopterin
-
T cell lymphoma is treated by administering to a patient suffering from T cell lymphoma a therapeutically effective amount of 10-propargyl-10-deazaaminopterin. Remission is observed in human patients, even with drug resistant T cell lymphoma at weekly dosages levels as low as 30 mg/m2. In general, the 10-propargyl-10-deazaaminopterin is administered in an amount of from 30 to 275 mg/m2 per dose.
