In 1930, the oxidised compound Oxophenarsine, containing an As=O unit, was identified as the active ingredient and was later marketed under the trade name Mapharsen. Mapharsen was used until the 1940s when it was replaced by Penicillin. Mapharsen was actually synthesised in Ehrlich’s laboratory as compound number 5, but it was believed to be too toxic for any clinical application .
Generally, the use of arsenic-based drugs has ceased, especially as a result of the development of Penicillin. Nevertheless, Melarsoprol and an arsenic-based drug closely related to Atoxyl are licensed to treat sleeping sickness. Oxaliplatin (cis-[oxalato] trans-1,2-diaminocyclohexane platinum(II)), for example, marketed under the trade name Eloxatin, is considered as a third-generation platinum-based anticancer drug. Its structure differs from previously synthesised platinum compounds by the configuration of its amino substituents. Its platinum centre is coordinated by two chelating ligands, namely an oxalate ligand and a so-called DACH (1,2-diaminocyclohexane) ligand. In comparison to cisplatin, the two chlorine leaving groups are replaced by an oxalato leaving group. The simple amino groups are replaced by the DACH ligand, which is the nonleaving group.
The clinical use of oxaliplatin was approved by the European Union in 1999 and by the FDA in 2002. It is most effective in combination with 5-fluorouracil and leucovorin (5-FU/LV) in the treatment of metastatic carcinomas of the colon or rectum. Oxaliplatin induces less side effects than cisplatin; for example, it is less nephrotoxic and ototoxic and leads to less myelosuppression. Unfortunately, treatment with oxaliplatin can lead to nerve damage, which may not be reversible in the case of chronic exposure of the patient to the drug. Oxaliplatin is usually administered intravenously as infusion over a period of 2–6 h in doses similar to cisplatin. The neurotoxic side effects are dose-limiting .
