Title: Improvements in and relating to the manufacture of derivatives, of the anthraquinone series
IPC: C09B1/52
Filed: 1926-04-21
Abstract: 274,558. Carpmael, W., (I. G. Farbenindustrie Akt..Ges). April 21, 1926. Anthraquinone derivatives.-Homonuclear substituted anthraquinone sulphonic acids are converted into hydrogenated compounds by treatment with a hydrosulphite in weak acid or weak alkaline solution. The hydrogenated compounds revert to the original compounds on careful 'oxidation in acid solution, for example with persulphate, but on boiling their aqueous solutions, or adding an alkali, or heating with concentrated sulphuric acid with or without boric acid, sulphonic groups are readily split off as sulphurous acid leaving non-hydrogenated anthraquinone derivatives. The hydrogenated compounds need not be isolated prior to the removal of the sulpho group and in the case of disulphonic acids one or both sulpho groups may be split off as desired. According to examples (1) 1-amino-4-oxyanthraquinone-3-sulphonic acid (free acid) is dissolved in water in the cold with the aid of sodium carbonate, hydrosulphite added, and the hydrogenated compound isolated by addition of potassium chloride; by warming the product with water, ammonia, or sodium carbonate solution, or by adding caustic soda to the aqueous solution in the cold, 1-amino-4-oxyanthraquinone quickly separates; (2) p-diaminoanthrarufin-2 : 6-disulphonic acid (Specification 12,011/97) is reduced to the hydrogenated compound which is isolated by adding sodium bisulphite; by heating with concentrated sulphuric acid, or by treating with caustic soda solution, p-diaminoanthrarufin-6- monosulphonic acid is obtained; the remaining sulphonic group can similarly be removed from the latter, or by working with larger quantities of hydrosulphite in the first place both sulphonic groups may be removed at the same time : (3) anthrarufin is produced directly from its 2: 6- disulphonic acid sodium salt by heating with water and hydrosulphite.. p-Diaminoanthrarufin- 3 : 7-disulphonic acid and p-diaminochrysazin- 2 : 7-disulphonic acid behave similarly to pdiamimoanthrarufin-2 : 6-disulphonic acid. The preparation of the following compounds is also mentioned :-quinizarin from its 2-sulpho acid, purpurin from its 3-sulpho acid, 1-aminoanthraquinone from its 2-sulpho acid, 1 : 5-diaminoanthraquinone from its 2 : 6-disulpho acid, and 1-amino-4-bromanthraquinone from its 2-sulpho acid. The treatment of the compounds described in Specification 250,968 is excluded. Specification 17206/99 also is referred to. 1-Amino-4-oxyanthraquinone-3-sulphonic acid is obtained from 1-oxyanthraquinone by sulphonating, nitrating, and reducing. p-Diaminoanthrarufin-3 : 7-disulphonic acid is obtained by oxidation of 1: 5-diaminoanthraquinone-2 : 6-disulphonic acid.

Title: Improvements in the preparation of spiramycins ó and ó¾
Filed: 1958-04-03
Abstract: Spiramycin II and III, which are less toxic than spiramycin I and are respectively the acetyl and propionyl derivatives of spiramycin I, or mixtures thereof, are produced by culturing Streptomyces ambofaciens NRRL 2420, or a mutant thereof, under aerobic conditions on a nutrient medium in the presence of (a) an acetylating agent which is acetic acid, a salt thereof such as the alkali metal salts, an ester, acetamide, or a substance producing these compounds in situ, e.g. butyric acid and its salts or (b) a propionylating agent which is propionic acid, a salt thereof such as the alkali metal salts, an ester, propanol, propionamide or a p  substance producing these compounds in situ, e.g. valeric acid and its salts.  The acylating agents may be used in quantities of 0.1 to 30 g. per litre and may be added in aqueous or organic solvent, e.g. methanol solution at the beginning of the fermentation or in stages during the fermentation. The transformation is facilitated by the presence in the nutrient medium of (a) chlorine anions in quantities of 0.1 to 20 g./litre as alkali metal or alkaline earth metal chloride, and (b) cations of magnesium, iron and cobalt in quantities of 0.1 to 500 mg. per litre in the form of salts such as chloride, nitrate or sulphate which do not hinder the transformation.  Streptomyces ambofaciens is cultured to produce the acylating enzyme in a medium containing (a) glucidic source of energy, e.g. glucose or starch in quantities of 1 to 100 g. per litre and (b) a source of ammoniacal nitrogen, e.g. ammonium chloride, sulphate or nitrate in quanties of 0.1 to 10 g. per litre. The pH is 5 to 9 and preferably 6.5 to 7.5 and is maintained within this range by the presence of calcium carbonate or the addition of a neutralizing substance as required.  The temperature is 15 DEG  to 40 DEG  C. and especially 22 DEG  to 27 DEG  C. and the duration 30 to 150 hours.  The whole culture or the separated mycelium is then used to produce the spiramycin II, III, or mixtures thereof.  In the presence of an acetylating agent spiramycin II is the main product whereas in the presence of a propionylating agent spiramycin III is the main product.  Since the whole culture contains naturally produced propionylating agents, the production of spiramycin II in high yield is obtained when the separated mycelium is used in the main transformation process wherein spiramycin I, as such, or as a salt, or in admixture with spiramycins II and III is incorporated in the culture medium in addition to the acylating agent and nutrients. Specification 758,726 is referred to.
