the head and neck cell lines. Further evaluation of 9 against CCRF-CEM and its sublines having defined mechanisms of MTX resistance demonstrated that the analogue utilizes the reduced folate/MTX-transport system and primarily inhibits DHFR and poly-gamma-glutamylation plays a role in its mechanism of action. Compound 9 was found to be 3-fold more efficient than aminopterin as a substrate for human folylpolyglutamate
