4-Formyl-N-isopropylbenzamide (cas: 13255-50-0) belongs to amides. The amide group is called a peptide bond when it is part of the main chain of a protein, and an isopeptide bond when it occurs in a side chain, such as in the amino acids asparagine and glutamine. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.SDS of cas: 13255-50-0
Mechanism of the cytostatic action of methylhydrazines. III was written by Weitzel, Guenther;Schneider, Friedhelm;Hirschmann, Wolf D.;Durst, Juergen;Thauer, Rudolf K.;Ochs, Hans Dieter;Kummer, Dieter. And the article was included in Zeitschrift fuer Physiologische Chemie in 1967.SDS of cas: 13255-50-0 This article mentions the following:
Hydrazine acetate (225-750 γ) injected i.v. into mice bearing Ehrlich ascites tumors reduced the incorporation rate of thymidine (I) and leucine (II) into the tumor cells dependent on dose; uridine (III) incorporation was not influenced. I.p. injections of Natulan (IV) (4-[(2-methylhydrazino)methyl]-N-isopropylbenzamide) and Azo-Natulan (4-(methylazomethyl)-N-isopropylbenzamide) (10 mg.) into mice bearing ascites tumors preferentially reduced the incorporation of III and also reduced I and II incorporation. Demethylated IV (4-(hydrazinomethyl)-N-isopropylbenzamide) reduced II and III, but not I incorporation. In the presence of NADPH, liver microsomes split IV to give HCHO. N-Isopropyl-4-formylbenzamide (1-2 × 10-3M) inhibited III and II and, to a lesser extent, I incorporation into ascites cells in vitro and produced similar results when injected at 15 mg. into ascitic mice. The biosynthesis of proteins in a cell-free system was not inhibited by hydrazine acetate, methylhydrazine, formalhydrazine, benzylhydrazine, 1-methyl-2-benzylhydrazine, IV, or demethylated IV. The spontaneous reaction of the IV degradation product, N-isopropyl-4-formylbenzamide, with amino acids produced Schiff bases, which could inhibit II incorporation by removing amino acids from protein synthesis. The synthesis of DNA and RNA was affected in the following manner. Hydrazine acetate (1-2 × 10-3M) inhibited the formation of purine deoxynucleosides. The HCHO resulting from the Me group of methylhydrazine inhibited the formation of deoxynucleoside diphosphates and deoxynucleoside triphosphates. The substituent N-isopropylcarbamide in the para position on the benzene ring inhibited the entrance of nucleosides and purines into the cell, resulting in a general lowering of the intracellular content of nucleosides and purines. In addition to condensation with amino acids, the aldehyde group of the N-isopropyl-4-formylbenzamide inhibited the formation of the nucleoside diphosphates and nucleoside triphosphates. All of these effects could be demonstrated simultaneously for IV and Azo-Natulan. 27 references. In the experiment, the researchers used many compounds, for example, 4-Formyl-N-isopropylbenzamide (cas: 13255-50-0SDS of cas: 13255-50-0).
