Eflornithine is an agent that can be used to treat glioma, especially glioma of WHO Grade II or Grade III such as anaplastic glioma. Eflornithine can suppress or prevent mutations in glioma which can cause the glioma to progress to a higher grade. The present invention describes pharmaceutical compositions that contain eflornithine or a derivative, analog, or prodrug thereof. The pharmaceutical compositions can be prepared in a number of dosage forms and may contain another therapeutically active agent or an agent that enhances the therapeutic activity of the eflornithine or the derivative, analog, or prodrug thereof. The present invention also describes a kit that includes dosage forms of pharmaceutical compositions according to the present invention.

Reactions of H[AuCl4] with N-substituted 2-pyridine thiocarboxamide ligands 2-(C5H4N)C(S)NHR (R = p-C6H4Me, CH2Ph, Me, p-C6H4OMe) gave cycloaurated derivatives (C5H4N)C(S)NR}AuCl2, with the ligand bonded as the thiol tautomer through the deprotonated SH group and the pyridine N atom to give a five-membered metallacyclic ring. The X-ray structure determination of the R = CH2Ph derivative shows a square-planar gold(III) complex that dimerises in the solid state by weak Au center dot center dot center dot S intermolecular interactions. In contrast, in the reaction of H[AuCl4] with 2-(C5H4N)C(S)NHR where R = 2-pyridyl, the ligand was oxidised to give a 1,2,4-thiadiazolo[2,3-a] pyridinium heterocyclic ring that was crystallographically characterised.
