Reactions of Carboxylic Acid Derivatives I

This is probably the single most important reaction of carboxylic acid derivatives. The overall transformation is defined by the following equation, and may be classified either as nucleophilic substitution at an acyl group or as acylation of a nucleophile. For certain nucleophilic reagents the reaction may assume other names as well. If Nuc-H is water the reaction is often called hydrolysis, i...

Studies on Arsenoxide Derivatives. Part I. Toxicity of Carbamidophenylarsenious Acid in Comparison with Carbarsone

Arsenical derivatives have played a useful part iu the treatment of amebiasis. Stovarsol, originally prepared by Ehrlich, was found to be effective in the control of this disease. But, owing to the higli percentage of toxic manifestations and other symptoms of arsenic intolerance, this product has been practically replaced in recent years by less toxic drugs. Anderson and Reed (1931) introduced...

Preparation and spectroscopic studies of cobalt(II) derivatives of blue copper proteins.

Preparation of cobalt(II) derivatives of type 1 copper proteins has been extended to include bean plastocyanin and azurin from Pseudomonas aeruginosa. Fluorescence quenching data suggest that Co(II) binds to the type 1 site of both apoplastocyanin and apoazurin. Electronic absorption spectral measurements have been made for cobalt(II)-stellacyanin, cobalt(II)-plastocyanin, and cobalt(II)-azurin...

Unidimensional Thin Layer Chromatography of Salicylic Acid Derivatives on Boric Acid-Impregnated Plates in Drugs Studies

A unidimensional Thin Layer Chromatography system for the separation of salicylic acid and its derivatives (sulfosalicylic acid and Aspirin) has been developed. The separation was successfully using a solvent system of chloroform-methanol-water-ammonium hydroxide 120:75:6:2 (V/V) as mobile phase on TLC plates impregnated with boric acid. The method is based on different behavior of investigated...

Studies on the Stability of Simple Derivatives of Sialic Acid.

The sinlic acids, whose chemistry and metabolism have been reviewed repeatedly in the recent past (l-5), are important constituents of many biological heteropolymers. It is quite clear that the multiple types of linkage in which a nonulosaminic acid can engage may influence the outcome of reactions designed to demonstrate its presence, cstimatc its quantity, or determine its modes of attachment...
