PPARy modulator

In conclusion, the need for better therapies to combat the approaching obesity and diabetes epidemic justifies the work that is required to solve the current problems associated with the development of PPARy modulators.

Enamine 106 underwent an intramolecular Heck reaction using palladium on charcoal to afford benzoyl indole 107 in 74% yield after crystallization from heptane/EtOAc [155]. Benzoyl indole 107 is an intermediate for a Merck PPARy modulator. 

The Mori-Ban reaction has been widely used in drug discovery and development. In the process synthesis of a selective PPARy modulator by Merck, the enamine was cyclized to afford the indole core. ... 

Other mechanisms, apart from PPARy modulation, have been reported and proposed to explain the observed protective effects exerted by nitroalkenes. An important pro-inflammatory pathway regulated by NO2-FA is the translocation to the nucleus of the nuclear factor-kappa B (NF-kB) transcription factor (Cui et al. 2006 Rudolph et al. 2010). NF-kB remains inactive in the cytosol bounded to the IkB repressor both NO2-LA and NO2-OA modulate the release of the transcription factor by nitroalkylating the NF-KB-p65 protein subunit leading to a decrease on lipopoly-saccharide-induced secretion of pro-inflammatory cytokines in macrophages (e.g. IL-6, TNFa, MCP-1). Similar mechanisms were reported for the inhibition of the expression of the vascular cell adhesion molecule 1 (VCAM-1) as well as monocyte rolling and adhesion (Cui et al. 2006).
