title: Synthesis of a magnosalin derivative, 4-(3,4,5-trimethoxyphenyl)-6-(2,4,5-trimethoxyphenyl)-2-diethylaminopyrimidine, and the anti-angiogenic and anti-rheumatic effect on mice by oral administration.
abstract: We describe here the synthesis and the anti-angiogenic and anti-rheumatic activities of 4-(3,4,5-trimethoxyphenyl)-6-(2,4,5-trimethoxyphenyl)-2-diethylaminopyrimidine (TAS-202), a derivative of magnosalin, which is a natural product isolated from Flos magnoliae. TAS-202 inhibited the proliferation of vascular endothelial cells more potently than magnosalin, and when given orally it inhibited basic fibroblast growth factor (bFGF)-induced angiogenesis and collagen-induced arthritis in mice. This magnosalin derivative with anti-angiogenic effects is a candidate for the treatment of rheumatoid arthritis.
