专利号:US-4794176-A 优先权日:1981-06-26 标 题 :Synthesis of tumor antigenic determinant 发明人:LEMIEUX RAYMOND U; RATCLIFFE ROBERT M; BAKER DONALD A 权利人:CHEMBIOMED 摘要:Processes are provided for the synthesis of the human T-antigenic determinant 2-acetamido-2-deoxy-3-O-(β-D-galactopyranosyl)-α-D-galactopyranoside containing an α-O-glycosidically linked bridging arm O--(CH 2 ) n COR. The determinant is coupled to carrier molecules to form artifical T-antigens, and to insoluble supports to form T-immunoadsorbents. The artificial T-antigen is shown to elicit a delayed type hypersensitivity reaction as a diagnostic for the presence of cancer in humans.

Said patterns are specifically substituted. Said process results in oligosaccharides usable particularly in therapy.
专利号:US-4012448-A 优先权日:1976-01-15 标题:Synthesis of adriamycin and 7,9-epiadriamycin 发明人:SMITH THOMAS H; FUJIWARA ALLAN N; HENRY DAVID W; LEE WILLIAM W 权利人:STANFORD RESEARCH INST 摘要:A process for the synthesis of adriamycin and 7,9-epiadriamycin, both active antineoplastic agents, in which 7-deoxydaunomycinone, in either the 9s or racemic (±) form, is employed as the starting material, the process in one embodiment also being productive of the useful intermediate compound 4-methoxy-6,11-dihydroxy-7,8-dihydro-5,9(10H),12-naphthacenetrione. The process involves converting 7-deoxydaunomicinone successively to daunomycinone, adriamycinone, 14-0-p-anisyldiphenylmethyladriamycinone and finally to adriamycin or to both adriamycin and 7,9-epiadriamycin. When producing the latter mixture of diastereomers, the 7-deoxydaunomycinone starting material is first converted to racemate form by a process involving the successive production of 7-deoxydaunorubicinol, 4-methoxy-6,11-dihydroxy-7,8-dihydro-5,9(10H), 12-naphthacenetrione, (±)-4-methoxy-9-cyano-6,9,11-trihydroxy-7,8,9,10-tetrahydro-5,12-naphthacenedione, (±)-4-methoxy-9-cyano-9-(2'-tetrahydropyranyloxy)-6,11-dihydroxy-7,8,9,10-tetrahydro-5,12-naphthacenedione and (±)-7-deoxydaunomycinone.
