Action of some substituted anthranilic acids on Escherichia coli.
Rydon (1) has found that 4and 5-methylanthranilic acids inhibit the growth of Eberthella typhi and that this inhibition is reversed by anthranilic acid, indole, and tryptophan. He concluded that the two methyl compounds interfere with the synthesis of tryptophan at the stage of anthranilic acid. Interruption in the conversion of anthranilic acid to indole in Escherichia coli, caused by chloromy...
متن کاملThe Action on Tyrosine and on Phxnylamino- Acetic Acid of Acetic Anhydride and Acetone in the Presence of Pyridine
There are recorded in literature several instances in which the acylation of amino acids in the presence of pyridine proceeded abnormally. ’ We have encountered an unexpected reaction in attempting to acetylate I-tyrosine suspended in. a solution of pyridine in commercial acetic anhydride (containing 90 to 95 per cent of the pure anhydride). From the reaction product a orystalline substance, CM...
متن کاملThe Racemization of Amino Acids in Aqueous Solution by Acetic Anhydride
In a previous investigation du Vigneaud and Sealock (1) have reported that the sodium salt of acetyl-l-tryptophane in aqueous solution at 35-40” is completely racemized by acetic anhydride within a few hours. The ease of racemization and particularly the mild conditions under which the reaction occurred seemed to us to offer an excellent method for racemizing amino acids if the reaction should ...
