Amine oxidase substrates for impaired glucose tolerance correction

Area of Science:

• Biochemistry
• Metabolic Research
• Endocrinology

Background:

• Amine oxidases, including semicarbazide-sensitive amine oxidase (SSAO), are enzymes involved in amine metabolism.
• SSAO is expressed in various mammalian cells and linked to functions like glucose transport.
• Emerging evidence suggests roles beyond simple amine scavenging, particularly concerning metabolic regulation.

Purpose of the Study:

• To review the insulin-like actions of amine oxidase substrates on metabolic processes.
• To explore the potential of amine oxidase substrates in managing metabolic disorders.
• To assess the impact of dietary amines on metabolic control.

Main Methods:

• Review of independent studies on SSAO and monoamine oxidase substrates in adipocytes.
• In vivo studies involving acute and chronic administration of amine oxidase substrates in rodent models.
• Analysis of dietary supplementation effects with specific amines on metabolic parameters in rodents.

Main Results:

• SSAO and monoamine oxidase substrates replicate insulin effects like glucose transport activation, lipogenesis stimulation, and lipolysis inhibition in adipocytes.
• Acute and chronic administration of amine oxidase substrates improved glucose tolerance and exhibited antihyperglycemic effects in diabetic rats.
• Dietary amines influenced metabolic control in rodents, enhancing glucose tolerance and reducing lipid mobilization without significant changes in lipid peroxidation or protein glycation markers.

Conclusions:

• Amine oxidase substrates possess insulin-mimetic properties with potential therapeutic applications for metabolic diseases.
• Ingested amines are not fully metabolized intestinally and can impact adipose and vascular tissues.
• The role of amines in food and nutraceuticals on metabolic control warrants further investigation.
