Development of analogs of thalidomide
The development of analogs of thalidomide was precipitated by the discovery of the anti-angiogenic and anti-inflammatory properties of the drug yielding a new way of fighting cancer as well as some inflammatory diseases after it had been banned in 1961. The problems with thalidomide included; teratogenic side effects, high incidence of other adverse reactions, poor solubility in water and poor absorption from the intestines.In 1998 thalidomide was approved by the US Food and Drug Administration (FDA) for use in newly diagnosed multiple myeloma (MM) under strict regulations. This has led to the development of a number of analogs with fewer side effects and increased potency which include; lenalidomide, (currently marketed), pomalidomide and apremilast (currently marketed), all of which are manufactured by Celgene.
