| It’s worth noting that there has been a lot of controversy around Sinclair and his work. > Sirtris Pharmaceuticals, Inc. was a biotechnology company based in Cambridge, MA that developed therapies for type 2 diabetes, cancer, and other diseases. Conceived in 2004 by Harvard University biologist David Sinclair and serial entrepreneur Andrew Perlman, and founded that year by Sinclair and Perlman, along with Christoph Westphal, Richard Aldrich, Richard Pops, and Paul Schimmel, the company was focused on developing Sinclair's research into activators of sirtuins, work that began in the laboratory of Leonard P. Guarente where Sinclair worked as a post-doc before starting his own lab. > Sirtris went public in 2007 and was subsequently purchased and made a subsidiary of GlaxoSmithKline in 2008 for $720 million. GSK paid $22.50/share, when Sirtris's stock was trading at $12/share, down 45% from its highest price of the previous year. > Studies published in 2009 and early 2010 by scientists from Amgen and Pfizer cast doubt on whether SIRT1 was directly activated by resveratrol and showed that the apparent activity was actually due to a fluorescent reagent used in the experiments. > GSK/Sirtris terminated development of SRT501 in late 2010. GSK said it was terminating SRT501 due to side effects of nausea, vomiting, and diarrhea it caused, and because the compound's activity wasn't specific to SIRT1, at some doses it actually inhibited SIRT1, and the compound itself wasn't patentable. — https://en.wikipedia.org/wiki/Sirtris_Pharmaceuticals > In February 2022, Sinclair raised widespread controversy in the longevity research community by rejecting to communicate in an academic debate in which his resveratrol research was criticized after months of mounting evidence against reseveratrol as a longevity intervention. — https://en.wikipedia.org/wiki/David_A._Sinclair |
This is the important detail in that story.
