Antirheumatic agents. III. Novel methotrexate derivatives bearing an indoline ring and a modified ornithine or glutamie acid

Matsuoka, Hiroharu,Kato, Nobuaki,Ohi, Nobuhiro,Miyamoto, Katsuhito,Mihara, Masahiko,Takeda, Yasuhisa

, p. 1146 - 1150 (2007/10/03)

The synthesis, biological profile and structure-activity relationship of various methotrexate (MTX) derivatives bearing an indoline ring are described. In particular, Nδ-(3-carboxyphenyl)-Nα-[1-[(2,4-diaminopteridin- 6-yl)methyl]indoline-5-ylcarbonyl]-L-glutamine (3d), compared to MTX; exhibited an enhanced anti-proliferative effect on human peripheral blood mononuclear cells obtained from healthy volunteers.
