Abstract:
TGR5 agonists are potential therapeutics for a variety of conditions including type 2 diabetes, obesity, and inflammatory bowel disease. After screening a library of chenodeoxycholic acid (CDCA) derivatives, it was determined that a range of modifications could be made to the acid moiety of CDCA which significantly increased TGR5 agonist potency. Surprisingly, methylation of the 7-hydroxyl of CDCA led to a further dramatic increase in potency, allowing the identification of 5.6 nM TGR5 agonist 17.

The ETC is embedded in the inner mitochondrial membrane and is comprised of four main protein complexes and an ATP synthase. NADH and FADH2 pass electrons to these complexes, which pump protons into the intermembrane space. This distribution of...

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...

Nomenclature of Carboxylic Acid Derivatives: Acid Halides, Esters, and Acid Anhydrides
The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.
