Francisco Velasquez and co-workers at Merck have reported in Organic Letters on the synthesis of some HCV (hepatitis C virus) NS5B (non-structural 5B) polymerase inhibitors. Someone once told me that when industry publishes in academic journals, it usually means the project was a failure. I wonder if that is the case here.

Natural product chemists, whether they are isolation chemists or total synthesis type chemists, all must justify the existence of the field to the layman by claiming that the biological activities of the molecules they either uncover or synthesize are interesting. Sometimes these compounds are way too toxic and unrealistic to be used by patients with diseases, so they argue for those compounds by stating that the toxic compounds are “tools” used in biology. Some way or another there will always be biology intertwined with the chemical structure. Well here is an example of an old familiar compound having new biological activity:
