title: New thiophene substituted 10-deazaaminopterins: synthesis and biological evaluation.
abstract: Analogues of 10-deazaaminopterin (10-DAM) and 4-amino-4-deoxy-10-deazapteroyl-gamma-methylene glutamic acid (MDAM) in which the benzene ring was replaced with a thiophene ring have been synthesized and evaluated for their antitumor activity. These analogues were N-([5-(2,4-diamino-6-pteridinyl)ethyl]-2-thenoyl)-L- glutamic acid (1) and N-([5-(2,4-diamino-6-pteridinyl)ethyl]-2-thenoyl)-gamma-meth ylene glutamic acid (2).
