Studies in Carcinogenesis with Azo Compounds II. The Action of Azo Compounds in Mice, and the Bearing Thereof on Theories of Azo Dye Carcinogenesis*
The results of earlier investigations of the carcinogenic action of azo dyes in rats were summarized by Kinosita in 1937 and 1940 (22, 23), and by Hartwell in 1941 (17). Since then much work has been done involving various types of controlled, restricted diets and a theory has been evolved (19) to account for the activity of certain dyes and the inactivity of others. A short review of this work...
متن کاملStudies on Highly Soluble Azo Sulfonamides.
Since the early observations of Kellner (1936) and Fuller (1937), who demonstrated that p-aminobenzenesulfonamide (sulfanilamide) is formed in animal tissues when prontosill or prontosil soluble2 (neoprontosil3) is administered by mouth, and the studies by Domagk (1935), Colebrook and Kenney (1936), and Colebrook, Buttle, and O'Meara (1936), wherein they were unable to demonstrate an antibacter...
متن کاملAzo complexes of osmium(II): preparation and reactivity of organic azide and hydrazine derivatives.
Mixed-ligand hydride complexes OsHCl(CO)(PPh3)2L (2) [L = P(OMe)3, P(OEt)3] were prepared by allowing OsHCl(CO)(PPh3)3 (1) to react with an excess of phosphite P(OR)3 in refluxing toluene. Dichloro compounds OsCl2(CO)(PPh3)2L (3, 4) were also prepared by reacting 1, 2 with HCl. Treatment of hydrides OsHCl(CO)(PPh3)2L (2), first with triflic acid and then with an excess of RN3 afforded organic a...
متن کاملAdvances and mechanistic insight on the catalytic Mitsunobu reaction using recyclable azo reagents
Ethyl 2-arylhydrazinecarboxylates can work as organocatalysts for Mitsunobu reactions because they provide ethyl 2-arylazocarboxylates through aerobic oxidation with a catalytic amount of iron phthalocyanine. First, ethyl 2-(3,4-dichlorophenyl)hydrazinecarboxylate has been identified as a potent catalyst, and the reactivity of the catalytic Mitsunobu reaction was improved through strict optimiz...
متن کاملSynthesis and Cyclic Voltammetric Studies of Bis[5-((4-Alkoxyphenyl)Azo)-N-(nPentyl, nDodecyl)-Salicylaldiminato] Copper(II) Complex Homologues
5-((4-alkoxyphenyl)azo)salicyladehyde, 5-((4-alkoxyphenyl)azo)-N-(npentyl, ndodecyl)-salicyladimine and bis [5-((4-alkoxyphenyl)azo)-N-(npentyl, ndodecyl)-salicyladiminato]copper(II) [alkoxy=OnCnH2n+1; n=3-7] homologues were synthesized and characterized by elemental analyses, mass and IR spectra. All complex homol...
