    Tryptophan and thiosemicarbazide derivatives: design, synthesis, and biological evaluation as potential β-d-galactosidase and β-d-glucosidase inhibitors
    摘要:
    Glycosidases, including beta-d-galactosidase and beta-d-glucosidase, are involved in a range of metabolic disorders, such as cancer, viral or bacterial infections, and diabetes. Previously, we scanned the pharmacophoric space of these enzymes and had a self-consistent and predictive quantitative structure-activity relationship that was used to identify several beta-d-galactosidase and beta-d-glucosidase inhibitors via in silico search of structural databases. Guided by the preceding modeling efforts, synthesis of a series of tryptophan and thiosemicarbazide derivatives as beta-d-galactosidase and beta-d-glucosidase inhibitors that match the generated pharmacophores followed by in vitro bioassay was carried out. Synthesized compounds 3c (37 % inhibition at 100 A mu M) and 4d (49 % inhibition at 100 A mu M) exhibited the best inhibitory bioactivities against beta-d-galactosidase and beta-d-glucosidase, respectively. They can serve as a promising lead compounds for the development of potential glycosidase inhibitors.

    The direct mechanochemical amidation of esters by ball milling is described. The operationally simple procedure requires an ester, an amine, and substoichiometric KOtBu and was used to prepare a large and diverse library of 78 amide structures with modest to excellent efficiency. Heteroaromatic and heterocyclic components are specifically shown to be amenable to this mechanochemical protocol. This
