Bakuchiol from Cullen corylifolium and its efficacy on apoptosis and autophagy in HepG2 cells

Overview 

Hepatocellular carcinoma (HCC) is the third most prevalent cause of cancer-related fatalities globally, with mortality rates reaching up to 85% in developing nations. This study investigates the anticancer properties of bakuchiol, the primary active component derived from the traditional medicinal herb Cullen corylifolium, against HepG2 liver cancer cells. The research aimed to elucidate bakuchiol’s specific mechanisms in inducing apoptosis, autophagy, and cell cycle arrest when compared to three other structurally similar flavonoids.

Key Findings

• Isolation and Cytotoxicity: Bakuchiol was identified as the most abundant component in the C. corylifolium ethanol extract, yielding $11.02 \pm 0.34$ mg/g. Among the four components evaluated, bakuchiol demonstrated the most potent cytotoxicity against HepG2 cells, recording an $IC_{50}$ of $70.0 \pm 0.67$ $\mu g/mL$.
• Induction of Apoptosis: Bakuchiol acts as a potent inducer of apoptosis by successfully engaging both intrinsic and extrinsic signaling cascades. It dose-dependently increases the ratio of Bax to Bcl-2 (intrinsic pathway markers) and the ratio of tBid to Bid (extrinsic pathway markers). Furthermore, a 100 $\mu M$ concentration of bakuchiol remarkably increased the ratios of cleaved caspase-3 and cleaved PARP, which are critical indicators of programmed cell death.
• Cell Cycle Arrest: Treatment with 100 $\mu M$ of bakuchiol caused a significant cell cycle arrest, increasing the proportion of cells in the sub-G1 phase from 1% to 18%. This arrest is driven by the upregulation of cell cycle inhibitory markers p53, p21, and p27, alongside a simultaneous decrease in the expression of CDK2 and CDK4.
• Promotion of Autophagy: Bakuchiol actively facilitates autophagy by modulating key cellular pathways. It significantly elevates the activity of AMPK (a positive regulator of autophagy) and increases the LC3II/LC3I ratio, while simultaneously suppressing Akt and mTOR (negative regulators of autophagy).
• Molecular Docking and Binding: In molecular docking simulations targeting VEGFR-2—a key mediator of tumor angiogenesis—bakuchiol demonstrated a strong binding energy of -8.54 kcal/mol. It established a successful hydrogen bond with the Cys919 amino acid residue, sharing a binding pocket similar to the known anti-angiogenic drug lenvatinib.

Conclusion This study is the first to report the significant antitumor efficacy of bakuchiol against HepG2 hepatocellular carcinoma cells. By effectively inducing both apoptosis and autophagy, and by modulating crucial signaling pathways, bakuchiol emerges as a highly promising natural therapeutic candidate for liver cancer research and treatment.

Cutaneous delivery and biodistribution of a lipophilic natural product – bakuchiol: Comparing nanocarrier performance

Overview 

Bakuchiol (BAK) is a lipophilic natural meroterpene widely recognized as a functional analogue of retinol, capable of targeting similar cellular pathways to improve skin photo-damage and stimulate collagen production. However, because it is an oil at ambient temperature and possesses high lipophilicity (log Ko/w 6.1), creating effective, consumer-friendly aqueous formulations presents a significant challenge.

Objective 

This study investigated and compared the performance of various nanocarriers—specifically micelles, microemulsions (ME), and nanoemulsions (NE)—in developing aqueous formulations of BAK and facilitating its successful delivery into the skin.

Methodology 

The researchers formulated and tested three main types of systems:

• Micelles prepared via solvent evaporation using D-a-Tocopherol polyethylene glycol 1000 succinate (TPGS) and Poloxamer 407 (P407).
• Microemulsions (ME) developed through a water microtitration method using oleic acid, Labrasol, Transcutol P, and water.
• Nanoemulsions (NE) produced via ultrasonication, yielding two variants: NE1 (containing oleic acid) and NE2 (without oleic acid).

Key Findings

• Encapsulation and Size Profile: The optimized TPGS and P407 micelles achieved high encapsulation efficiencies of 96.6 ± 3.2% and 101.5 ± 0.3%, respectively, with very small particle sizes of roughly 27 to 28 nm.
• Emulsion Performance: NE2 demonstrated an encapsulation efficiency of 106.8 ± 5.7%, which was higher than both NE1 (90.2 ± 2.4%) and the ME (86.3 ± 4.6%). The emulsion-based formulations exhibited larger particle sizes than the micelles, ranging from 68 nm (NE2) to 129 nm (NE1).
• Superior Skin Deposition: During finite dose cutaneous delivery tests, the nanoemulsions (NE1 and NE2) achieved 3 to 4 times higher BAK skin deposition than either the micelles or the microemulsion.
• Role of Oleic Acid: The inclusion of oleic acid, a known chemical penetration enhancer, in NE1 did not result in superior skin delivery compared to NE2, which did not contain it.
• Targeted Biodistribution: Nanoemulsions effectively targeted the viable epidermis and dermis, which are the critical sites for BAK’s collagen-stimulating biological effects. Specifically, NE2 successfully deposited BAK concentrations in these deeper skin layers that were up to 36-fold higher than the minimum effective concentration required for efficacy.

Conclusion 

The study concludes that for highly lipophilic natural compounds like BAK, nanoemulsions are superior delivery vehicles compared to micelles and microemulsions. Furthermore, the findings indicate that a formulation’s thermodynamic activity and the molecular properties of the penetrant are far more critical for effective skin delivery than simply minimizing the physical size of the nanocarrier.

Bidirectional regulation of bakuchiol, an estrogenic-like compound, on catecholamine secretion

Overview

Bakuchiol is a natural phytoestrogen isolated from the seeds of Psoralea corylifolia L., a plant with a long history of use in Traditional Chinese medicine. This study investigates the regulatory effects of bakuchiol on the secretion of catecholamines (CAs)—vital neurotransmitters such as epinephrine, norepinephrine, and dopamine—and evaluates its potential therapeutic efficacy against depression and stress.

Key In Vitro Findings: Bidirectional Regulation

Using cultured bovine adrenal medullary cells as a model, researchers discovered that bakuchiol exerts a unique bidirectional, or dual, effect on CA secretion:

• Stimulation of Basal Secretion: Bakuchiol independently stimulated baseline CA secretion in a concentration-dependent manner. This stimulation acts through bakuchiol’s estrogen-like binding properties and the JNK signaling pathway, occurring even without extracellular calcium.
• Enhancement of CA Synthesis: The compound promotes the synthesis of new CAs by elevating the phosphorylation of tyrosine hydroxylase (the rate-limiting enzyme in CA synthesis) at specific sites (Ser31 and Ser40) via the ERK1/2 and PKA pathways.
• Suppression of Excess Secretion: Conversely, when cells were stimulated by secretagogues like acetylcholine, veratridine, or high potassium, bakuchiol significantly inhibited the resulting excess CA secretion. This inhibitory action is directly related to bakuchiol’s ability to suppress sudden rises in intracellular calcium levels.

Key In Vivo Findings: Behavioral and Physiological Impacts

To assess the practical mental health implications of these cellular mechanisms, the researchers conducted behavioral despair and chronic stress tests on mice:

• Anti-Depressant-Like Activity: In both the tail suspension test and the forced swim test, administration of bakuchiol significantly reduced immobility time in mice, suggesting an anti-depressant effect. Crucially, open-field tests confirmed that bakuchiol achieved this without abnormally altering general locomotor activity.
• Anti-Stress Activity: Using a chronic immobilization stress model, the study showed that bakuchiol significantly reduced stress-induced spikes in plasma epinephrine and norepinephrine levels over a 7-day period.

Conclusion

Bakuchiol acts as a potent bidirectional regulator of the catecholamine system. By safely elevating basal CA synthesis while simultaneously preventing the excessive CA overflow associated with acute stress, bakuchiol emerges as a highly promising candidate for treating clinical depression and stress-related disorders.
