We know that Imatinib (its mesylate salt, Novartis) is a drug used to treat certain types of cancer. It is used in treating chronic myelogenous leukemia (CML), gastrointestinal stromal tumors (GISTs) and a number of other cancers. It is the first member of a new class of agents that act by inhibiting particular tyrosine kinase enzymes, instead of non-specifically inhibiting rapidly dividing cells.More over the discovery of this compound itself is interesting & its one drug obtained via, High Throughput Screening (HTS). Chemists used a HTS of chemical libraries to identify the molecule 2-phenylaminopyrimidine. This lead compound was then tested and modified by the introduction of methyl and benzamide groups to give it enhanced binding properties, resulting in imatinib. More interesting part of this drug is a recent discovery, i.e., GLEEVEC® (imatinib mesylate) can be used to treat Scleroderma. As per the claim by the researchers, until now no drug has been shown to be effective in treating scleroderma in a clinical trial. Several years ago, a small study provided some evidence that a chemotherapy drug called cyclophosphamide may help scleroderma patients, but the benefit was minimal and this drug causes side effects including infertility and secondary cancers.
The investigators reported an interim analysis of their results, although the study is ongoing. At one year, the investigators saw a 23 percent improvement in skin scores. The researchers also saw an improvement in forced vital capacity scores by 9.6 percent and diffusion capacity scores by 11 percent in the 18 patients who had completed one year of treatment. The lung function data was really exciting,” Dr. Spiera said. “In patients with scleroderma, you usually see lung function tests getting worse over time, and if doctors try a therapy for a year and a patient doesn’t get any worse, we get pretty excited. What is amazing to me in this study is that we actually saw improvements in both lung function tests. Congrats for this remarkable achievement.....
