Abstract

The lysine analogue (4) of methotrexate (1) was treated with 5-(dimethylamino)naphthalene-l-sulfonyl chloride to give the corresponding dansyl analogue 5. The product isolated by preparative TLC was further purified on a preparative HPLC column. Analogue 5 exhibited fluorescence properties characteristic of the dansyl moiety and was a potent inhibitor of dihydrofolate reductase purified from Lactobacillus casei, chicken liver, and a human lymphoblastoid cell line.
