Chlorogenic acid: A dietary phenolic acid with promising pharmacotherapeutic potential

A K Singh et al, 2022. Chlorogenic acid: A dietary phenolic acid with promising pharmacotherapeutic potential, Current Medical Chemistry.

Phenolic acids are now receiving a great deal of interest as pervasive human dietary constituents that have various therapeutic applications against chronic and age-related diseases. One such phenolic acid that is being utilized in traditional medicine is chlorogenic acid (CGA). It is one of the most readily available phytochemicals that can be isolated from the leaves and fruits of plants such as coffee beans (CoffeaarabicaL.), apples (Malus spp.), artichoke (Cynara cardunculus L.), carrots (Daucus carota L.), betel (Piper betle L.), burdock (Arctium spp.) and so on. Despite its low oral bioavailability (about 33%), CGA has drawn considerable attention due to its wide range of biological activities and numerous molecular targets.Several studies have reported that the antioxidant and antiinflammatory potential of CGA mainly account for its broad-spectrum pharmacological attributes. CGA has been implicated in exerting beneficial role against dysbiosis by encouraging the growth of beneficial GUT microbes. At biochemical level its therapeutic action is mediated by free radical scavenging efficacy, modulation of glucose and lipid metabolism, down-regulation of proinflammatory cytokines such as tumor necrosis factor alpha (TNF-α),interleukin-6 (IL-6), IL-1β, and interferon gamma (IFN-γ), upregulation of nuclear factor erythroid 2-related factor 2 (Nrf-2) and inhibition ofthe activity of nuclear factor- κβ (NF-κβ) and thus help inmanagement of diabetes, cardiovascular diseases, neurodegenerative disorder, cancer, hypertension etc. This review highlights the natural sources of CGA, its bioavailability, metabolism, pharmacotherapeutic potential and underlying mechanisms of action for clinical usefulness of CGA in the management of health disorders.
