Flavonoids, a diverse group of polyphenolic compounds found in plants, exhibit a wide range of biological activities that make them promising candidates for drug development. However, their roles are not straightforward, as they can act both as drugs and pro-drugs. Their pharmacological potential is often tempered by their complex bioavailability and the diverse metabolic pathways they undergo. This overview explains the dual roles of flavonoids, their pharmacological and toxicological promiscuity and their primary action on the Gastrointestinal (GI) tract due to their low bioavailability.
Flavonoids are abundant in fruits, vegetables and various plant-derived foods. They are classified into several subclasses, including flavones, flavonols, flavanones, flavanols and anthocyanins. These compounds are known for their antioxidant, anti-inflammatory, anti-cancer and cardiovascular benefits. Their structural diversity allows them to interact with various molecular targets, which supports their potential as therapeutic agents.
Flavonoids can function as direct-acting drugs, exerting therapeutic effects through mechanisms such as enzyme inhibition, receptor modulation and antioxidant activity. Conversely, flavonoids can act as pro-drugs. In this capacity, they are metabolized into active compounds within the body. The biotransformation of flavonoids typically involves processes such as glycosylation, methylation and sulfation, leading to the production of metabolites that may maintain enhanced or distinct biological activities compared to their parent compounds.
The term "pharmacological promiscuity" refers to the ability of flavonoids to interact with multiple biological targets, leading to a broad spectrum of pharmacological effects. On one hand, it allows flavonoids to exert multifaceted therapeutic effects, such as anti-inflammatory, antiviral and neuroprotective actions. On the other hand, it complicates the prediction of their pharmacodynamics and potential off-target effects. Flavonoids' ability to modulate multiple signaling pathways simultaneously can be beneficial in treating complex diseases like cancer and neurodegenerative disorders. However, this same property can lead to unintended interactions and side effects, emphasizing the need for careful evaluation of their pharmacological profiles.
In addition to their therapeutic potential, flavonoids can exhibit toxicological promiscuity. Their ability to interact with multiple targets can result in toxic effects, particularly at high doses or with chronic exposure. Due to their low bioavailability, flavonoids and their metabolites often exert significant effects on the gastrointestinal tract. After oral ingestion, flavonoids undergo extensive metabolism by gut microbiota and enterocytes, leading to the formation of various metabolites. These metabolites can modulate gut health by influencing microbial composition, enhancing intestinal barrier function and exerting local anti-inflammatory effects.
The GI tract serves as a primary site for the pharmacological action of flavonoids. For example, certain flavonoids have been shown to reduce the risk of colon cancer by modulating gut microbiota and inhibiting inflammatory pathways. Their local effects on the GI tract can be beneficial, but they also raise concerns about potential toxicities, such as irritation or disruption of normal gut flora.
Flavonoids represent a complex and multifaceted class of compounds with significant potential as drugs and pro-drugs. Their pharmacological and toxicological promiscuity highlights both their therapeutic versatility and the challenges in their development. The gastrointestinal tract, as a primary target due to low bioavailability, plays an important role in mediating the effects of flavonoids and their metabolites. Understanding the complex balance between their beneficial and adverse effects is essential for utilizing their full potential in therapeutic applications.
