Studies on Furan Derivatives. XI. Test for Antitumor Activity of Nitrofuran Derivatives

Metabolism of drugs. LXXX. The metabolic fate of nitrofuran derivatives. 3. Studies on enzymes in small intestinal mucosa of rat catalyzing degradation of nitrofuran derivatives.

The enzymes responsible for the degradation of nitrofuran derivatives in rat small intestinal mucosa were examined in vitro.As a result,it was suggested that the initial reactions in the degradation of 2-(2-furyl)-3-(5-nitro-2-furyl)acrylamide(AF-2) and 5-nitro-2-furfural semicarbazone(nitrofurazone)are mainly catalyzed by xanthine oxidase , while that of 2-amino-5-[2-(5-nitro-2-fury1)-1-(2-fur...

Antitumor activity of derivatives of mycophenolic acid.

One hundred and eight derivatives of mycophenolic acid (MA) have been prepared by modifications at the phenolic hydroxyl and/or carboxyl sites. None of these compounds was as effective as MA in suppressing cell growth of L-518Y cell in vitro, whereas several compounds with changes at both the hydroxyl and carboxyl groups were more effective than MA against Ehrlich solid carcinoma and L-1210 leu...

Synthesis of Furan Derivatives Condensed with Carbohydrates

Eight new furan derivatives have been prepared and characterized. These compounds were obtained by condensation of aminosugar and aminocyclitol intermediates with furan derivatives.

Studies on nicotinamide derivatives.

Studies on pyrazine derivatives. XLVII. Synthesis and antibacterial activity of novel pyrazine derivatives with amidoxime moiety.

The new pyrazine derivatives exhibiting an antibacterial activity have been synthesized. Initial amidoxime 1 was obtained in the reaction of pyrazinecarbonitrile with hydroxylamine. Upon treatment of amidoxime with methyl iodide O-methyl derivative 2 was formed. Both amidoximes were transformed into imidoyl chlorides 3, 4. Then the chloride atom in those derivatives was substituted with various...
