(* CHEMICAL STRUCTURE *) (I) Platinum (II) complexes of formula (I) where: Am is a monodentate amine, or (Am)2 is a bidentate amine, B represents a straight or branched alkyl residue or a single bond, R is selected from the group of hydrogen, (C3-C8) cycloalkyl, phenyl or naphthyl which may be substituted by halogens (I, Br, Cl, F), trihalomethane, hydroxyl, (C1-C4)-alkoxyl, (C1-C7)-acylamino, (C1-C7)-sulphamido, allyl, phenoxyl, haloalkoxyl, nitro, cyano, azido, with condition that when R is hydrogen B is different from a single bond, Q is a residue of formula -(CH2)n1-CRaRb-(CH2)n2-, 1,2- or 2,3-naphthalene, benzo-1,3-dioxolan-5,6-diyl, substituted or unsubstituted 1,2-phenylene, Ra and Rb are selected independently of each other from the group of hydrogen, allyl, linear or branched (C1-C8)-alkyl, -(CH2)pOH, -(CH2CH2O)q-CH3, or taken together with the carbon atom to which they are bonded form a (C3-C8) cycloalkyl, or heterocyclic tetrahydropyran-4,4-diyl, n1 and n2 are independently zero or the integer 1, p is an integer from 2 to 6, and q is an integer from 1-3, X- is a biocompatible anion such as chloride, bromide, iodide, nitrate, perchlorate, or one equivalent of sulphate or phosphate, or an anion of a monovalent C1-C4 organic acid such as acetate, propionate or chloroacetate, or of an aromatic acid such as benzoate, or of a heteroaromatic acid such as nicotinate are described. The compounds are useful as anti-tumor drugs. |
