Catecholamine Derivatives: Natural Occurrence, Structural Diversity, and Biological Activity.

Area of Science:

• Natural Products Chemistry
• Medicinal Chemistry
• Biochemistry

Background:

• Catecholamines (CAs) are aromatic amines with a 3,4-dihydroxyphenyl nucleus and an amine side chain.
• Key examples include epinephrine, norepinephrine, and dopamine, crucial endogenous neurotransmitters.
• CAs and their derivatives are vital for G-protein coupled receptor (GPCR) research and sympathomimetic drug development.

Purpose of the Study:

• To review catecholamine derivatives isolated from natural sources.
• To summarize their diverse biological activities and structural variations.
• To provide insights into future research and development of CAs.

Main Methods:

• Literature review of recent decades focusing on CA derivatives.
• Identification and isolation of CAs from microorganisms, plants, insects, and marine invertebrates.
• Analysis of reported biological activities and structural properties.

Main Results:

• Numerous CA derivatives have been identified across diverse natural sources.
• These compounds exhibit a wide spectrum of biological activities.
• CAs possess valuable properties like adhesion, reactivity, metal chelation, redox activity, biocompatibility, and degradability.

Conclusions:

• Catecholamines and their derivatives represent a rich source of biologically active natural products.
• Their structural and biological diversity is extensive, with regular patterns in natural occurrence.
• Further research into CAs holds significant promise for novel therapeutic agents and scientific applications.
