NUS chemists have discovered a class of iron compounds that induces cancer cell death, leaving healthy cells unharmed.<\/p>\n<p>Iron is an extremely important element present in the human body. Although iron serves multiple purposes, it is most well-known as an oxygen carrier in red blood cells. Despite its ubiquity and natural compatibility with many bodily functions, it is surprising that not much research has been carried out in exploiting iron compounds as potential anti-cancer agents. Instead, compounds which contain the more expensive and rare platinum metal such as cis-platin continue to be much more heavily studied. Prof FAN Wai Yip and his research team from the Department of Chemistry, NUS have have found that a particular class of iron compounds called cyclopentadienyl iron carbonyls CpFe(CO)<sub>2<\/sub>X (X=halide, NCS, BF<sub>4<\/sub><sup>&#8211;<\/sup> and CpFe(CO)<sub>2<\/sub>) can induce apoptosis, or programmed cell death, in breast cancer and cervical cancer cell lines. This discovery suggests that less expensive iron compounds could be potential drug candidates for anti-cancer treatments.<\/p>\n<p>Preliminary investigations into the mode of action suggest that a free-radical type of reaction involving reactive oxygen species was induced by the iron compounds and this eventually led to cancer cell death. Normal healthy cells are unaffected by the iron treatment since these cells tend to contain smaller amounts of free radicals. Many of these iron compounds are metabolic-stable and demonstrate good permeability across a lipid barrier. This means that they are suitable candidates for <em>in vivo<\/em> studies.<\/p>\n<p>The researchers intend to study the mechanism of action involved when the iron compounds \u201ckill\u201d the cancer cells. With this knowledge, they can then develop more effective compounds which can also be applied to other types of cancer cells. The iron compounds used in this study are inexpensive. They are commercially available or can be easily prepared. Through this study, the researchers hope to stimulate interest in using iron compounds to develop cost effective anti-cancer therapeutic agents.<\/p>\n<p>&nbsp;<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" alt=\"76.
