Daptomycin (CAS NO.103060-53-3) was originally discovered by researchers at Eli Lilly and Company in the 1980s, who designated the compound LY 146032. It showed promise in Phase I/II clinical trials for the treatment of infections caused by Gram-positive organisms. However, high dose therapy was found to be associated with adverse effects on skeletal muscle, including myalgia and the potential for myositis, and Lilly ceased development. The rights to LY 146032 were subsequently acquired by Cubist Pharmaceuticals in 1997. Food and Drug Administration (FDA) approval in September 2003. Daptomycin is marketed in the EU and several other countries by Novartis following its buying of Chiron Corporation. Outside of the US, Daptomycin is available in Canada and many European countries, with further launches expected in 2008.

4. Use of Daptomycin
Daptomycin is a novel lipopeptide antibiotic used in the treatment of certain infections caused by Gram-positive organisms. Its distinct mechanism of action means that it may be useful in treating infections caused by multi-resistant bacteria.
