Mycobactin S

Mycobactin S has been isolated from Mycobacterium smegmatis and from Mycobacterium sp. Olitzky & Gershon, strain 2, and mycobactin H from M. thermoresistible; all three organisms were grown on synthetic media of low iron content. These two mycobactins are mixtures of compounds having the same nucleus but differing in their fatty side chains. The nucleus of mycobactin S has a chemical structure identical with that of mycobactin T but differs in the optical configuration at the β-carbon atom of the hydroxy acid fragment; the configuration in mycobactin S is S whereas that in mycobactin T is R (the previous assignment of this configuration was incorrect). The cobactin fragment of mycobactin H is identical with that of mycobactin S, but the mycobactic acid moiety differs in having methyl groups at position 6 in the benzene ring and at position 5 in the oxazoline ring. The configurations of all the asymmetric centres have been established for both mycobactins. Improved and simplified methods for the extraction and purification of mycobactins are described.

Abstract The DC and AC polarographic response of nitroglycerin in the nonaqueous medium of acetonitrile-0.1M tetrabutylammonium perchlorate is presented. DC polarographic results are shown to be superior with respect to sensitivity limits and linearity of the response (wave height) vs. concentration profile. DC polarography is applied successfully to the analysis of two types of commercial formulations containing nitroglycerin. The results are compared with other methods for the determination of nitroglycerin, e.g., infrared, the phenoldisulisulfonic acid procedure for organic nitrates, and a column chromatographic procedure.
