ABSTRACT OF THE DISCLOSURE Acylated mitosenes having the formula OCOR compound. They are useful antibacterial agents.
The present invention relates to novel derivatives of mitomycin and, more especially, to compounds produced by reductive acylation of mitomycin.
In 1956, mitomycin A and mitomycin Bcompounds having anti-tumor potency as well as antibacterial activitywere isolated by Hata et al. from a culture medium of Streptomyces caespitosis. Subsequently, Wakaki et al. isolated mitomycin C from a culture medium of the same microorganism. It is known that mitomycin C, which also has anti-tumor and antibacterial activities, is one of the most potent of the known anti-tumor substances. However, its clinical utilization is restricted because of its relatively high toxicity. Thus, as is pointed out on page 687 of The Merck Index, Seventh Edition (1960), published by Merck and Co., Inc., Rahway, NJ mitomycin C has been used primarily against far advanced malignancies.
It is a desideratum in this art to embody new therapeutically useful compounds which retain the advantages of the mitomycins, particularly those of mitomycin C, e.g. possess the antibacterial potencies thereof, but are free of the disadvantage thereof, namely, are of such reduced toxicity as effectively to broaden the possibilities of use thereof.
The present invention realizes this desideratum by embodying novel acylated mitosenes which are useful inter alia for the purposes for which, e.g., mitomycin C is used and in essentially the same way, but with the elimination of the aspect of undue, and thereby sometimes prejudical, toxicity.
The chemical structure of the mitomycins is as shown by the formula:
| C1120 C ONH:
wherein X, Y and Z have the following significances:
Mitomyeln A B C 01130 NH:
H0 onto OH: H
The following mitomycin derivatives are also known:

When according to the present invention, a compound E the Formula I, II or IH is concurrently subjected to re action of an acylating agent and a chemical reducing gent in pyridine or is subjected to catalytic hydrogenaon in solution in a mixture of an acylating agent and yridine, reductive acylation takes place in accordance ith the following schemes:

N-C OR OCOR I =RCO O or RC Ohal RCO herein ==H or or NH;
I'=CH O, NH, or 0H j"=OCH NHCOR or OCOR =OH or OCH al=halogen (Cl, Br)
Note that the reductive acylation according to the pres- 1t invention involves the splitting of the azirrdine ring t the cases of starting compounds I and II.
The acylating agent is preferably an acid anhydride or an acid halide, corresponding to the acyl group to be introduced. Preferred in this regard according to the invention are acetic anhydride and acetyl chloride, whereby the acetyl group is introduced into the molecule.
Chemical reducing agents are the so-called moderate reducing agents such as sodium hydrosulfite, although preference is given to zinc in this regard. In the catalytic reduction alternative, use can be made of any of the conventional hydrogenating catalysts such as platinum oxide, rhodium oxide, Raney nickel and the like, but palladiumon-carbon is preferred.
The reactions shown on the foregoing reaction schemes are preferably carried out in a solvent medium, such as pyridine.
Where hydrogen is the reducing agent, the reaction is allowed to proceed until one mole of hydrogen has been adsorbed per mole of starting compound.
Work-up of the reaction mixture is as illustrated in the exemplary embodiments, infra.
On the accompanying sheet of drawing:
FIG. 1 shows the infrared absorption spectrum of the product of the reductive acetylation of 1 hydroxy-Z- amino-7-hydroxy-mitosene (cf. Example 1); and
FIG. 2 shows the infra-red absorption spectrum of the product of the reductive acetylation of 1 hydroxy-Z- methyl-amino-7-methoxy-mitosene (cf. Example 2).
The following examples set forth, by way of illustration, but not of limitation, presently preferred typical em bodiments of the invention. In these examples, parts by weight bear the same relation to parts by volume as do grams to milliliters.
Example 1 (CHsC 0) O pyridine zinc (L ke .AcO- CEzOCONHz I N 0A0 0A2 I NHAe (Ao=CH;C O)
500 parts by weight of l-hydroxy-2-amino-7-hydroxymitosene are dissolved in 10 parts by volume of acetic anhydride and 10 parts by volume of pyridine, to which 500 parts by weight of zinc powder have been added. The mixture is vigorously agitated in ice. The resultant colorless solution is filtered to remove zinc. The filtrate is concentrated under reduced pressure (1 mm. Hg) and the residue is dissolved in ethyl acetate, followed by shaking the solution in water. The ethyl acetate solution is then dehydrated with Glaubers salt, after which it is subjected to silica gel chromatography. The main fraction is first eluted with acetone-ethyl acetate (2:1). 350 parts by weight of colorless pillar-shaped crystals are obtained by concentrating the eluate under reduced pressure.

When 1 mole of hydrogen has been absorbed, the reaction mixture is filtered to remove the catalyst. The filtrate is concentrated under reduced pressure and purified by silica gel chromatography after the manner described in Example 1. 170 parts by weight of colorless needles are obtained.
