Alzheimer's disease (AD) is associated with multiple neuropathological events including β-site amyloid precursor protein cleaving enzyme-1 (BACE-1) inhibition and neuronal inflammation, ensuing degeneracy, and death to neuronal cells. Targeting such a complex disease via a single target directed treatment was found to be inefficacious. Hence, with an intention to incorporate multiple therapeutic effects within a single molecule, multitarget-directed ligands (MTDLs) have been evolved. Herein, for the first time, we report the discovery of novel thiazolyl-thiadiazines that can serve as MTDLs as evident from the in vitro and in vivo studies. These MTDLs exhibited BACE-1 inhibition down to micromolar range, and results from the in vivo studies demonstrated efficient anti-inflammatory activity with inherent gastrointestinal safety. Moreover, compound 6d unveiled noteworthy antioxidant, antiamyloid, neuroprotective, and antiamnesic properties. Overall, results of the present study manifest the potential outcome of thiazolyl-thiadiazines for AD treatment.
A diversified assembly of 1,2,4-oxadiazol-3-amines: Metallic thiophile catalyzed chemoselective one-pot reaction of aryl isothiocyanates, amidines/guanidines, and hydroxylamine

An efficient one-pot synthesis of 1,2,4-oxadiazol-3-amines from simple starting materials, isothiocyanates, amidines/guanidines, and hydroxylamine, is described. The reaction is facilitated by metallic-thiophile-assisted desulfurization of in situ formed amidino- or guanidinothiourea to give chemoselectively N-hydroxyguanidine intermediates that give exclusively various 1,2,4-oxadiazol-3-amines in good to excellent yields. The reaction mechanistic pathway may proceed through an intramolecular 5-exo-trig cyclization.
