The invention relates to a compound of formula (I), wherein R1, R2, R3, R4, R5, n, m, p, X and Z are as defined in the description; and either the two bonds characterised by wavy lines are absent in ring A and replaced by a total of 4 hydrogen atoms, and the two wavy lines in ring B each, together with the respective parallel bond, signify a double bond; or the two bonds characterised by wavy lines are absent in ring B and replaced by a total of 4 hydrogen atoms, and the two wavy lines in ring A each, together with the respective parallel bond, signify a double bond; or both in ring A and in ring B all of the 4 wavy bonds are absent and are replaced by a total of 8 hydrogen atoms; or a salt thereof, if at least one salt-forming group is present. These have, for example, an antitumour effect. |
