About Cis-platin & other drivatives:
Cisplatin, cisplatinum, or cis-diamminedichloroplatinum(II) is a platinum-based chemotherapy drug used to treat various types of cancers, (sarcomas, some carcinomas (small cell lung cancer, and ovarian cancer), lymphomas, and germ cell tumors. It was the first member of a class of anti-cancer drugs which now also includes carboplatin and oxaliplatin. These platinum complexes react in vivo, binding to and causing crosslinking of DNA which ultimately triggers apoptosis (programmed cell death).
Now its the turn of Picoplatin [see structure , Amminedichloro(2-methylpyridine)platinium)], Poniard Pharmaceuticals, Inc. has come up with some interesting results from its Phase 2 trial of picoplatin in patients with metastatic colorectal cancer (CRC). Picoplatin, given once every four weeks in combination with 5-fluorouracil and leucovorin in the FOLPI regimen, has comparable efficacy to oxaliplatin, given in combination with 5-fluorouracil and leucovorin in the modified FOLFOX-6 regimen, as a first-line therapy for CRC, as assessed by one-year survival rate, progression-free survival (PFS) and disease control. The company claims that, (from the updated proof-of-concept Phase 2 safety and efficacy results) picoplatin could be superior to oxaliplatin as a neuropathy-sparing alternative when used in combination as a first-line treatment for metastatic colorectal cancer.
