Description
Substituted 1,3,9,1 l-tetraoxa-4,5,7,8-tetraazaundecadiene-4,7- dioxides-5,7 , their preparation and application
Field of the invention
The present invention relates to new chemical compounds - substituted 1,3,9, 1 1 - tetraoxa-4,5,7,8-tetraazaundecadiene-4,7-dioxides-5,7 with general structure Fl , to methods of their preparation, and to pharmaceutical compositions, containing these compounds.
Fl
Specifically, such compounds can act as potential donors of nitric oxide NO in living organisms, and as strong cytostatic agents they can be employed in cancer chemotherapy
Background of the invention
Malignant tumors still remain between the leading human death factors in most of the industrial countries. Therefore elaboration of new, more effective malignant tumors therapy methods, including new anticancer drugs, is a vital necessity One of possible methods to solve such problem is employment of chemical compounds, which are capable to liberate in vivo nitric oxide NO - an unique biological mediator, having cytotoxic properties (Hibbs J. B. et. al., Biochem Biophys. Res Comm., 1988., vol. 157., nr. 1 , pp. 87-94 ).
From structural analogues to the claimed compounds F l in scientific and patent information as nitric oxide NO donors, cytostatic agents and wide spectrum medicines are offered nitric oxide NO and nucleophile adducts of the general structure F2 Here J is a radical, connected with an active moiety via heteroatom, but M is metal, etc cation (Maragos C M. et. al., WO 93/20806, publ. 28.10.1993 ).

N .0 N
F2
Chemically they represent nitric oxide NO adducts with primary and secondary amines, etc
Second group of known related compounds are by F2 alkylation obtained substituted alkoxydialkyltriazene-N-oxides with general structure F3, where Ri - R.. are different organic residues (Keefer L. K. et. al., WO 93/071 14, publ. 15.04. 1993 ).
Compounds with similar structure, substituted l ,7-dioxa-2,3,5,6- tetraazaheptadiene-2,5-dioxides-3,5 (see F4) are known as chemical substances
CHHUOBCKHH B. H. H jφ., >K. Opr. XHM., 1980., T. 16.,Bbiπ. 5., crp. 933-936 ),
F4
but we cannot found any biomedical information about them Published analogues (see F4) have Rι=R4 and they are lower alkyls, any further transformations were done at the central carbon atom.
Compounds with structure F5 are offered (Tsien R. Y. et. al., WO 94/27957) as nitric oxide NO donors after photochemical activation.

F5
In this structure A represents oxygen or nitrogen containing substituent, but B is photolytically unstable group
Compounds with general structures F2 and F3 have some serious disadvantages
1. During F2 and F3 decomposition in solutions strongly carcinogenic N- nitrosa ines are formed as by-products; this fact is confirmed in literature (Saavedra J E et. al., J Org Chem., 1992 , vol 57., nr.23., pp 6134-6138 )
2 Compounds F2 and F3 stability is not sufficient enough for galenic drugs preparation Published half-lifes of adducts F2 in buffered solution with pH=7,4 and 37°C temp, are few minutes up to half a hour (Keefer L. K. et al., J Med Chem , 1991 , vol 34., nr. 1 1., pp. 3242-3247 ). This fact corresponds to the authors conception about direct nitric oxide NO donors, but seriously burdens application of these compounds and galenic forms preparation for medical purposes
Any biomedical information, as far as we know, is not published on compounds with general structure F4
In compounds with general structure F5 substituent B (see F5) must be photolytically unstable, which seriously limits their medical application
For solving mentioned drawbacks we offer as anticancer drugs and potential nitric oxide NO donors substituted 1,3,9, 1 l-tetraoxa-4,5,7,8-tetraazaundecadiene-4,7- dioxides-5,7 (see Fl) In comparison with known F2 and F3 they have the following advantages:
1 Nitrosamine formation during destruction of the compound selfsame is ruled out, because molecules Fl do not contain chains from three interconnected nitrogen atoms
2. Half-life of compounds Fl in aqueous buffer with pH=7,4 and 37°C temp exceeds 24 hours, which is sufficient for infusion
3 In comparison with structures F2 and F3, compounds with general structure Fl have additional modification possibilities. By suitable radicals Ri - R8 (see F l ) selection the whole molecule may be constructed asymmetric at central carbon atom This gives additional chances for biological activity variation
Compounds F2 show cytostatic activity (WO 93/20806), they inhibit 3H- thymidine incorporation in DNA of human melanoma A-375-C6 cells to 50% at concentrations 24 - 280 μM.
In our structure-activity relation investigations of diazene oxides compounds with general structure Fl showed high cytostatic activity Thus, compound with (see Fl ) at concentration 4 μM shows
in DNA of mouse P-388 cells Standart compound N-methyl-N-n trosourea oes * not showed "Η-thymidine incorporation inhibition on this model at cone 1 μM
Obtained results together with mentioned compounds Fl advantages describes them as promising anticancer pharmaceuticals
Physico-chemical properties (see experimental part) of claimed compounds with general structure Fl allow their various application for galenic form preparation Galenic forms for oral use include
1 Solutions, comprising compounds Fl in therapeutically active amounts in suitable solvents, as water, ethanol, ethanol - water mixtures, dimethylsulfoxide, oils, etc., which in turn may contain other pharmaceutically acceptable ingredients, as well as conservants and stabilizing agents
2 Tablets, capsules or powders, which contain compounds Fl in therapeutically active amounts. In these forms employment of various colouring, diluting, conserving, etc modifying components, as microcrystalline cellulose, starch, saccharose, lactose, mannit, gelatin, sihcagel, as well as combination with other pharmaceutically acceptable ingredients is allowed
3 Aerosols, comprising compounds Fl in therapeutically active amounts, which are sprayed by pulverizator or pressurized propellant, as freon, propane, etc
Galenic forms for parenteral use include sterile injection solutions of compounds Fl in therapeutically active amounts in water or other solvents, as well as microcrystalline compounds Fl suspensions, which additionally may contain conserving, bacteriostatic, buffering agents, antioxidants, salts, as well as other pharmaceutically acceptable ingredients for galenic drug preparation This includes also ex tempore prepared injection solutions and suspensions
