✦ Synopsis


Abstract

The synthesis of novel analogues of foric acid (FA) antagonists derived from the pyrazino[2,3‐c]‐1,2,6‐thiadiazine 2,2‐dioxide system incorporating the glutamic acid side chain at the 7‐position is described. No significant DHFR inhibition of cytotoxic activity has been found with these compounds.
