标 题:Use of alpha-di(lower alkoxy) anthraquinones in the synthesis of Alizarin Saphirols
发明人：WHITE DAVID L; FITZPATRICK JOSEPH W
权利人:TOMS RIVER CHEMICAL CORP
摘要:Alpha-dihydroxyanthraquinones used as intermediates in the synthesis of many dyestuffs, such as the Alizarin Saphirols (e.g. Color Constitution No. 63000, 63005, 63010, 63011, 63315 and 63610) can be replaced on an equimolar basis by alpha-di(lower alkoxy)anthraquinones. The alpha-di(lower alkoxy) anthraquinones can be converted in a single step, by treatment with oleum, to the corresponding alpha-dihydroxyanthraquinone-beta-disulfonic acids in almost quantitative yield. The corresponding diamine is obtained by dinitrating followed by reduction of the nitro groups. The known intermediate, leuco 1,4,5,8-tetrahydroxyanthraquinone (see C.I. No. 62500) can be obtained either by reduction of the diamine or by reduction of the dinitro compound. In one embodiment, the alpha-di(lower alkoxy)anthraquinone is obtained from dinitroanthraquinone by treatment thereof with methanol and KOH.

发明人：HUANG HSU-SHAN
摘要:This invention relates to novel anthraquinone compounds useful in the treatment of allergic, inflammatory conditions, antioxidant, tumor condition, stem cell application, tissue engineering, applied in treating age-associate tissue degeneration, reverse organ failure in chronic high-turnover disease and therapeutic compositions containing such compounds. The compounds of the present invention are 1,4-, 1,5- and 1,8-difunctionalized anthraquinones or analogs thereof. According to the practice of the invention, there are provided bis-symmetrical substituted anthraquinone compounds according to formula I: n n nwherein R1, R2, R3 and R4 present a straight, aminoalkylamino side chains or branched chain alkyl group having 1 to 6 carbons which may be substituted with one or more groups of R5, or R1, R2, R3 and R4 present phenyl or benzyl which may be substituted with one or two groups of R6; wherein R5 is selected from the group consisting of halogen, —RNH 2 , —RNH 2 R, —ROH, —NO 2 , —OCH 3 , —OCH 2 CH 3 , and —OCH 2 CH 2 CH 3 ; and wherein R6 is selected from the group consisting of a straight or branched chain alkyl group having 1 to 4 carbons, halogen, —RNH 2 , —RNH 2 R, —ROH, —NO 2 , —OCH 3 , —OCH 2 CH 3 , —OCH 2 CH 2 CH 3 , —CH 2 Br, —CH 2 Cl, —CH 2 OH, —C(CH 3 ) 3 , —(CH 2 ) 2 0H, —(CH 2 ) 3 OH, —(CH 2 ) 4 OH, —CH 2 NH 2 , —(CH 2 ) 2 NH 2 , —(CH 2 ) 3 NH 2 , —(CH 2 ) 4 NH 2 , —(CH 2 ) 5 NH 2 , —CH 2 N(CH 3 ) 2 , —(CH 2 ) 2 N(CH 3 ) 2 , —(CH 2 ) 2 NH(CH 2 ) 2 OH, —(CH 2 ) 3 NH(CH 2 ) 2 OH, —(CH 2 ) 2 NHCH 2 OH, —(CH 2 ) 3 NHCH 2 OH, —CH 2 CH(CH 3 ) 2 , —CHCl 2 , —CH(CH 3 )Cl, —(CH 2 ) 2 Cl, —(CH 2 ) 3 Cl, —(CH 2 ) 3 Br, —(CH 2 ) 4 Br, and —(CH 2 ) 4 Cl. n n Chart 1. Activation of hTERT promoter-driven SEAP expression by c-Myc. About 1×10 7 hTERT-BJ1 cells were transfected with 13.5 μg each of plasmid pSEAP or pPhTERT-SEAP and of plasmid pMT2T or pMT2T-cMyc by electroporation. After 24 h, viable cells were harvested, and reinoculated at a density of 3×10 5 /mL, and the SEAP activity after 24 h at 37 â–¡. The transfection efficiency of each experiment was determined by cotransfection with 1.5 μg of plasmid pCMVβ. The values were determined from three experiments. P<0.05 is presented by an asterisk.
