Sex hormone in cancer warfare

Inactive platinum complexes can be transformed into exciting anticancer compounds by coupling them with testosterone using a quick and simple method, claim UK scientists. This could pave the way for new target specific anticancer drugs. 

Platinum compounds cisplatin, carboplatin and oxaliplatin are commonly used to treat cancer. But these drugs can only treat a limited number of tumours and some types of cancer are now showing resistance. The drugs are also highly toxic and cause unwanted side effects. Drugs that target the site of disease without harming healthy tissue are better and have been explored by using the sex hormone oestrogen attached to a Pt compound. These target oestrogen receptors which are over-expressed in most breast cancer tumours.
