Development of disulfide-derived fructose-1,6-bisphosphatase (FBPase) covalent inhibitors for the treatment of type 2 diabetes
摘要:
Fructose-1,6-bisphosphatase (FBPase), as a key rate-limiting enzyme in the gluconeogenesis (GNG) pathway, represents a practical therapeutic strategy for type 2 diabetes (T2D). Our previous work first identified cysteine residue 128 (C128) was an important allosteric site in the structure of FBPase, while pharmacologically targeting C128 attenuated the catalytic ability of FBPase. Herein, ten approved cysteine covalent drugs were selected for exploring FBPase inhibitory activities, and the alcohol deterrent disulfiram displayed superior inhibitory efficacy among those drugs. Based on the structure of lead compound disulfiram, 58 disulfide-derived compounds were designed and synthesized for investigating FBPase inhibitory activities. Optimal compound 3a exhibited significant FBPase inhibition and glucose-lowering efficacy in vitro and in vivo. Furthermore, 3a covalently modified the C128 site, and then regulated the N125-S124-S123 allosteric pathway of FBPase in mechanism. In summary, 3a has the potential to be a novel FBPase inhibitor for T2D therapy. (C) 2020 Elsevier Masson SAS. All rights reserved.

Provided are compositions and methods for protecting a compound comprising a haloalkylamide moiety from metabolic transformation by hydrolases. In one aspect, the disclosure is directed to increasing the bioavailability and tissue delivery of a anti-HCV compound comprising a haloalkylamide moiety by protecting the compound from inactivation by carboxylesterases. Specific approaches for limiting metabolic transformation include use of carboxylesterase inhibitors to inhibit metabolism of the compound, or use of orally administered compositions designed to deliver the compound to the small intestine or large intestine. Further provided are methods of treating or preventing HCV infection in a subject.
