Platinum oxalate-complexes with N6-benzyladenine derivatives, process of their preparation and use of such complexes as medicaments in antitumor therapy

摘要

The platinum oxalate complexes of the + II oxidation stage and their crystallosolvates comprising the structural motif (I) or the general formula (II) represented by the structural formula [Pt (L). [Pt (L) (L ') (ox)], where L and L' represent N6-benzyladenine derivatives of general formula (IV) bonded to a platinum atom of the parent motif (V) via any nitrogen adenine independently selected from N1, N3, N6, N7 or N9, depending on the degree of substitution of the molecules.
