Apigenin is a natural compound known as a flavone, a class of flavonoids. It’s recognized for its promising bioactive properties, notably its potential role in promoting longevity and overall health, by virtue of its influence on cellular functions and its antioxidant, anti-inflammatory, and anti-cancer properties.
Apigenin is found abundantly in various plant foods, such as parsley, celery, and chamomile tea. It’s a subject of increasing research interest due to its diverse biological activities and its potential benefits in preventing and managing a range of health conditions, from metabolic disorders to age-related diseases.
Research on apigenin in the context of longevity focuses primarily on its ability to modulate several cellular pathways related to aging. Apigenin is studied for its potential to inhibit CD38, an enzyme that consumes NAD+, a vital coenzyme in cellular energy metabolism and repair processes. [1] By potentially maintaining or elevating NAD+ levels, apigenin could play a role in delaying the aging process and mitigating age-related declines in cellular function. Additionally, its antioxidative and anti-inflammatory properties contribute to its role in promoting cellular health and longevity.
Sources of Apigenin
Apigenin is predominantly found in a variety of plant foods, contributing to the beneficial effects of a plant-rich diet. It is also available in supplement form, offering a concentrated source for those seeking to leverage its potential health and longevity benefits.

(PMID 23172919) [PubMed] [DOI] [Full text] Metabolic syndrome is a growing health problem worldwide. It is therefore imperative to develop new strategies to treat this pathology. In the past years, the manipulation of NAD(+) metabolism has emerged as a plausible strategy to ameliorate metabolic syndrome. In particular, an increase in cellular NAD(+) levels has beneficial effects, likely because of the activation of sirtuins. Previously, we reported that CD38 is the primary NAD(+)ase in mammals. Moreover, CD38 knockout mice have higher NAD(+) levels and are protected against obesity and metabolic syndrome. Here, we show that CD38 regulates global protein acetylation through changes in NAD(+) levels and sirtuin activity. In addition, we characterize two CD38 inhibitors: quercetin and apigenin. We show that pharmacological inhibition of CD38 results in higher intracellular NAD(+) levels and that treatment of cell cultures with apigenin decreases global acetylation as well as the acetylation of p53 and RelA-p65. Finally, apigenin administration to obese mice increases NAD(+) levels, decreases global protein acetylation, and improves several aspects of glucose and lipid homeostasis. Our results show that CD38 is a novel pharmacological target to treat metabolic diseases via NAD(+)-dependent pathways.

Current treatments for Alzheimer's disease primarily focus on enhancement of cholinergic transmission. However, these treatments are only symptomatic, and no disease-modifying drug is available for Alzheimer's disease patients. This review will provide an overview of the proven antioxidant, anti-inflammatory, anti-amyloidogenic, neuroprotective, and cognition-enhancing effects of curcumin and apigenin and discuss the potential of these compounds for Alzheimer's disease prevention and treatment. We suggest that these compounds might delay the onset of Alzheimer's disease or slow down its progression, and they should enter clinical trials as soon as possible.

Phytochemicals present therein provide beneficial anti-inflammatory and antioxidant properties that serve to improve the cellular microenvironment. Compounds known as flavonoids categorized anthocyanidins, flavonols, flavanones, flavonols, flavones, and isoflavones have shown considerable promise as chemopreventive agents. Apigenin (4', 5, 7-trihydroxyflavone), a major plant flavone, possessing antioxidant, anti-inflammatory, and anticancer properties affecting several molecular and cellular targets used to treat various human diseases. Epidemiologic and case-control studies have suggested apigenin reduces the risk of certain cancers. Studies demonstrate that apigenin retain potent therapeutic properties alone and/or increases the efficacy of several chemotherapeutic drugs in combination on a variety of human cancers. Apigenin's anticancer effects could also be due to its differential effects in causing minimal toxicity to normal cells with delayed plasma clearance and slow decomposition in liver increasing the systemic bioavailability in pharmacokinetic studies. Here we discuss the anticancer role of apigenin highlighting its potential activity as a chemopreventive and therapeutic agent. We also highlight the current caveats that preclude apigenin for its use in the human trials.
