Pathogen yeasts infections are treated with fluconazole, that blocks the lanosterol 14-alpha demethylase. This enzyme is essential for the biosynthesis of ergosterol, that is essential for the permeability and rigidity of the fungal plasma membrane. The magnification shows the active site with fluconazole interacting with a heme group. Source PDB entry 5esf.

The glucagon like peptide-1 receptor (GLPr) is a G proteincoupled receptor (GPCR) that mediates the action of GLP-1, a peptide hormone. The activated receptor  has a strong effect  on the management of type 2 diabetes mellitus and obesity, including glucose homeostasis and regulation of gastric motility and food intake.

Fluconazole is an antifungal medication used to treat fungal infections like candidiasis and mycosis. Due to genetic mutations in the active site (red), fluconazol can't bind anymore to the target enzyme, the lanosterol 14 alpha-demethylase, while the substrate lanosterol (violet) can still bind and be transformed in ergosterol (blue). Ergosterol plays an important structural role in the regulation of membrane fluidity and permeability. Source: PDB entry 5esf.
