Biological context of thiadiazole

• PURPOSE: To compare Caco-2 monolayer permeability and in vivo bioavailability of microparticle with nanoparticle 301029, a thiadiazole derivative, and to determine whether nanonization could improve oral bioavailability of the poorly soluble compound [11].
• The method is applied to the thiadiazole class of stromelysin inhibitors and it takes advantage of the fact that, upon binding to the active site of enzyme, the thiadiazole ring, with its absorbance centered at 320 nm, is able to quench the fluorescence of the tryptophan residues surrounding the catalytic site [12].
• Exploring 3D-QSAR of thiazole and thiadiazole derivatives as potent and selective human adenosine A3 receptor antagonists+ [13].
