A convenient method for the preparation of hitherto unknown ([18F]fluorophenyl)acetylenes ([18F]FPAs) using the Seyferth-Gilbert homologation is reported. The novel building blocks were efficiently prepared from easily accessible [18F]fluorobenzaldehydes by using the Bestmann-Ohira reagent. High radiochemical yields and excellent radiochemical purities were achieved within only 20 min of reaction time; 2- and 4-[18F]FPAs were applied to prepare radiofluorinated heterocycles by using different cycloaddition and cross-coupling reactions. Additionally, these building blocks were used to prepare three novel PET tracers. Thus, an artificial radiofluorinated protected amino acid [18F]10, a COX-2-specific ligand [18F]14, and a PSMA-selective inhibitor [18F]16 were obtained in high radiochemical yields. A convenient method for the preparation of hitherto unknown ([18F]fluorophenyl)acetylenes ([18F]FPAs) utilizing the Seyferth-Gilbert homologation is reported. The novel building blocks were applied to prepare radiofluorinated heterocycles and PET tracers utilizing different cycloaddition and cross-coupling reactions.

Background: α-Glucosidase inhibitors have occupied a significant position in the treatment of type 2 diabetes. In this respect, the development of novel and efficient non-sugar-based inhibitors is in high demand. Objective: Design and synthesis of new 5-arylisoxazole-1,3,4-thiadiazole hybrids possessing α-glucosidase inhibitory activity were developed. Methods: Different derivatives were synthesized by the reaction of various 5-arylisoxazole-3-carboxylic acids and ethyl 2-((5-amino-1,3,4-thiadiazol-2-yl)thio)acetate. Finally, they were evalu-ated for their α-glucosidase inhibitory activity. Results: It was found that ethyl 2-((5-(5-(2-chlorophenyl)isoxazole-3-carboxamido)-1,3,4-thiadiazol-2-yl)thio)acetate (5j) was the most potent compound (IC50 = 180.1 μM) compared with acarbose as the reference drug (IC50 = 750.0 μM). Also, the kinetic study of 5j revealed a competitive inhibition and docking study results indicated desired interactions of that compound with amino acid residues located close to the active site of α-glucosidase. Conclusion: Good α-glucosidase inhibitory activity obtained by the title compounds introduced them as an efficient scaffold, which merits to be considered in anti-diabetic drug discovery developments.
