Abstract
The invention comprises compounds of the formula <FORM:0999582/C2/1> (wherein R1 is hydrogen, acyl or 2,4-dinitrophenyl and -CO.R2 is acyl or R1 and -COR2 together are succinyl, thus forming a 33-membered ring) and O-acyl derivatives and salts thereof; and their preparation by condensing 3 mols. of 1-amino-5-hydroxylaminopentane or 1-amino-5-nitro-pentane, 2 mols. of a succinic acid or anhydride, or an azide, imide, imidazolide or ester thereof, and 1 mol. of a carboxylic acid which may contain a second carboxyl group or a functional derivative thereof in any suitable order of succession, provided that (a) when 1-amino-5-nitro-pentane is used, the nitro group is reduced to the hydroxylamino group prior to the condensation with an acid or its derivative; (b) when an intermediate product containing an N-hydroxy-N-(b -carboxypropionyl) radical is condensed with 1-amino-5-nitro-pentane or with a 1-amino-5-N-acylhydroxylamino-pentane the intermediate product is converted into a dioxo-oxazine prior to the condensation; and (c) the free amino group of the terminal nitrogen atom in formula (I) is protected by a 2,4-dinitrophenyl group or an acyl group, and, if desired, from the final product the acyl group R1 is split off by hydrolysis or hydrogenolysis and, if desired, the product wherein R1 is a hydrogen atom and COR2 is a b -carboxypropionyl group is intramolecularly condensed to form a 33-membered ring. The products may be acylated at the terminal nitrogen atom, any O-acyl derivatives formed being converted into the O-unsubstituted N1-acyl compound by means of ammonia; or converted into N-(2,4-dinitrophenyl) derivatives; and COR2 groups can be exchanged and free carboxyl groups esterified. The products can also be converted into and released from their metal derivatives, e.g. natural ferrioxamines and derivatives thereof formed, for example, by acylation or esterification.

The desferri-ferrioxamines of the invention, which are stated to affect the metabolism of iron and other metals, and their physiologically tolerable salts, may be made up into pharmaceutical and veterinary compositions with suitable carriers. They may take the form of tablets, dragees, powders, ointments, creams, suppositories, vials, solutions, suspensions or emulsions, and may contain preserving, stabilizing, wetting or emulsifying agents.
