Definitions

  • the present invention relates to a series of new polycyclic aromatic alkaloids having a pyrido[2,3,4-&,/]acridine skeleton which have cytotoxic properties and which can therefore be used in the treatment of malignant tumours.
  • the invention also provides methods and compositions using these new compounds as well as processes for their preparation.
  • the polycyclic aromatic alkaloids based on the pyrido[2,3,4-£,/]acridine skeleton are a growing class of ascidian metabolites that often exhibit a variety of interesting biological properties, including antitumour activity.
  • This class of compounds comprises three main structural types, depending of the position of the fusion between the parent structure and additional rings present in the natural product.
  • cystoditines ⁇ have the base skeleton mentioned above, while amphimedine, ⁇ meridine ⁇ and cystodamine ⁇ bear an additional pyridine ring attached to the h bond; ascididemin, ⁇ its derivatives, ⁇ the kuanoniamines ⁇ and shermilamine A 9 show this additional ring at the face, and eilatine at both.10
  • Our target compounds can be regarded as regioisomers both of meridine and amphimedine, but they have not been so far isolated from natural sources.
  • X is selected from the group consisting of O, and NR 3 , where R 3 represents a lower alkyl group;
  • Y is selected from the group consisting of CH and N;
  • R 1 and R 2 are independently selected from the group consisting of NH 2 , NHR 4 and NR 5 2 , where R and R 5 each represent a lower alkyl group, or R 1 and R 2 together represent a cycle selected from (a), (b) and (c):
  • R 6 , R 7 and R 8 are independently selected from the group consisting of hydrogen atoms, lower alkyl groups, hydroxy groups and lower alkoxy groups;
  • Z is selected from the group consisting of O and NH; and pharmaceutically acceptable salts thereof.
  • the lower alkyl groups and the lower alkyl moiety of the lower alkoxy groups are straight-chain or branched alkyl groups having 1 to 6 carbon atoms such as methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl, tert-butyl, pentyl, neopentyl and hexyl groups.
  • R 6 and R 7 are preferably independently selected from the group consisting of hydrogen atoms, alkyl groups having from 1 to 4 carbon atoms, hydroxy groups and alkoxy groups having from 1 to 4 carbon atoms; more preferably, R and R are independently selected from the group consisting of hydrogen atoms, methyl groups and ethyl groups; and, most preferably, R 6 represents a methyl group and R 7 represents a hydrogen atom.

  • compositions include any solid (tablets, pills, capsules, granules, etc.) or liquid (solutions, suspensions or emulsions) dosage form, with suitable formulation of oral, topical or parenteral administration, and they may contain the pure compound or in combination with any carrier or other pharmacologically active compounds. These compositions may need to be sterile when administered parenterally.
  • a pharmaceutical composition comprising compounds with formula (I), will vary according to the pharmaceutical formulation, the mode of application, and the particular situs, host and tumor being treated. Other factors like age, body weight, sex, diet, time of administration, rate of excretion, condition of the host, drug combinations, reaction sensitivities and severity of the disease shall be taken into account. Administration can be carried out continuously or periodically within the maximum tolerated dose.
