Patent number: 8053583Abstract: Anti-cancer compounds and manufacturing methods thereof are disclosed. The anti-cancer compounds are 1,8-diamidoanthraquinone derivatives with amino compounds. The manufacturing method includes the steps of: add 1,8-bis(chloroacetamido)anthraquinone or 1,8-bis(3-chloropropionamido)-anthraquinone with amino compounds, catalysts, and dehydrated dimethylformamide (DMF) to form a mixture and react with one another. Then by purification and recrystallization, the anti-cancer compounds are obtained. The anti-cancer compounds of the present invention are compounds with whole new structure that overcome serious cardiac toxicity of the conventional anti-cancer drug-doxorubincin.Type: GrantFiled: March 7, 2009Date of Patent: November 8, 2011Assignee: National Defense Medical CenterInventor: Hsu-Shan Huang

Patent number: 6689828Abstract: Disclosed are thermally-stable, anthraquinone colorant compounds (dyes) which contain one or more vinyl groups which render the compounds copolymerizable with reactive vinyl monomers to produce colored, polymeric compositions such as acrylate and methacrylate polymeric materials. The compounds possess good fastness (stability) to ultraviolet (UV) light, good solubility in vinyl monomers, good color strength and excellent thermal stability. Also disclosed are (1) coating composition comprising (i) one or more polymerizable vinyl compounds, (ii) one or more of the dye compounds described above, and (iii) a photoinitiator and (2) polymeric materials, i.e., polymers derived from one or more acrylic acid esters, one or more methacrylic acid esters, one or more other polymerizable vinyl compounds or mixtures of any two or more thereof, having copolymerized therein one or more of the anthraquinone colorant compounds.Type: GrantFiled: July 24, 2001Date of Patent: February 10, 2004Assignee: Eastman Chemical CompanyInventors: Michael John Cyr, Max Allen Weaver, Gerry Foust Rhodes, Jason Clay Pearson, Phillip Michael Cook, Jos Simon De Wit, Larry Keith Johnson

Patent number: 5387704Abstract: Process for preparing amino- and carbamoyl-substituted anthraquinones by Diels-Alder reaction of an N-butadienylcarbamic acid ester of the formula H.sub.2 C.dbd.CH--CH.dbd.CH--NH--COOR.sup.2, wherein R.sup.2 is alkyl or phenylalkyl, with a 1,4-naphthoquinone or with 1,4-benzoquinone to form a carbamoyl-substituted hydroanthraquinone intermediate and by oxidation of this intermediate with an oxygen-containing gas in a tertiary amine and in the presence of a copper salt to obtain a carbamoyl-substituted anthraquinone product. The Diels-Alder reaction and the oxidation reaction can be carried out as a one-pot synthesis or in separate steps. The carbamic acid ester reactant provides a blocking group represented by --COOR.sup.2, and this blocking group is optionally removed by treatment of the carbamoyl-substituted anthraquinone with an alkaline hydroxide solution.Type: GrantFiled: November 9, 1993Date of Patent: February 7, 1995Assignee: BASF AktiengesellschaftInventors: Klaus Ebel, Juergen Schroeder
