The fibroblast growth factor receptor 1 (FGFR1) conjugate ferulic acid (FA) has IC50 values of 3.78 and 12.5 μM for FGFR1 and FGFR2, respectively. At 1 μM, ferulic acid demonstrates a 92% inhibition rate of FGFR1 core inhibitory action. Ferulic acid at 5 to 40 μM was treated for 24 hours, which resulted in a substantial reduction in the proliferation of FGF1-stimulated HUVEC. In HUVEC cells, ferulic acid up to 20 μM had no discernible influence on cell viability; however, over 30 μM, ferulic acid showed hazardous effects when compared to controls. In a dose-dependent manner, ferulic acid blocks the migration of HUVECs triggered by FGF1 as well as their transitory migration. Ferulic acid dramatically reduced the phosphorylation of PI3K and Akt that was generated by FGF1. FGF1 induction was markedly suppressed by ferulic acid. MMP-2 and MMP-9 expression [1].

Ferulic acid (FA) treatment successfully prevented FGF1-induced neovascularization. Comparing intragastric ferulic acid formulations to those treated with dimethyl sulfoxide (DMSO), it was observed that the former greatly inhibited tumor volume and tumor weight. Furthermore, the administration of ferulic acid was well tolerated, and no discernible variation in body weight was seen between the vehicle and FA-treated groups [1]. in the open field test, but had no impact on immobility time in the TST. The formulation of ferulic acid (0.001 mg/kg, po) improved the antidepressant-like action of fluoxetine (5 mg/kg, po) in TST, according to the data [2].

Rat Aortic Ring Assay:** Aortas were isolated from 6-week-old male Sprague-Dawley rats, cleaned of fat and connective tissue, and cut into rings. 48-well plates were coated with Matrigel. Aortic rings were placed in the wells and sealed with an additional overlay of Matrigel. FGF1 in serum-free M199 medium, with or without ferulic acid, was added to the wells. The medium was changed every 2 days. After 6 days, microvessel sprouting was fixed, photographed, and quantified. [1]
* **Chick Chorioallantoic Membrane (CAM) Assay:** Fertilized chicken eggs were incubated. A window was made in the shell to expose the CAM. FGF1, alone or in combination with ferulic acid, was applied to the CAM. After further incubation, neovascularization was observed and photographed. The absence of dead embryos was noted to rule out general toxicity. [1]
* **B16F10 Melanoma Xenograft Model:** Female C57BL/6 mice were subcutaneously implanted with 3 × 10⁶ B16F10 melanoma cells. On day 7, when tumors reached an appropriate size (150-300 mm³), mice were randomly divided into six groups: a control group, a positive drug group (dacarbazine), a vehicle-treated group (carboxymethyl cellulose), and three ferulic acid dosage groups (10, 30, 50 mg/kg). Mice were treated daily by intragastric administration with ferulic acid or vehicle. Tumor volume and body weight were measured every 3 days. Tumor volume was calculated as mm³ = 0.5 × length (mm) × width (mm)². On day 25, mice were euthanized, and tumor tissues were excised for further analysis, including immunohistochemistry. [1]
* **Immunohistochemistry:** Deparaffinized tumor sections from the xenograft model were stained with specific antibodies against CD31, p-FGFR1 (Tyr154), p-PI3K (p85 Tyr458), and p-Akt (Thr308). Detection was performed using an avidin-biotin-HRP complex and diaminobenzidine as the chromogen. Nuclei were counterstained with hematoxylin. [1]

Absorption, Distribution and Excretion
This study investigated the bioavailability of ferulic acid in humans after tomato consumption by monitoring the relationship between intake and excretion pharmacokinetics. Results showed that peak urinary ferulic acid excretion occurred approximately 7 hours later, and the recovery rate of urinary ferulic acid was 11-25% of the intake, based on the total amount of free ferulic acid and feruloyl glucuronide excreted. …This study examined the excretion of free and conjugated ferulic acid in urine after oral administration of Pinus maritima bark extract (PBE). Eleven healthy adult subjects (4 women and 7 men) received a single dose of 200 mg PBE or two doses of 100 mg and 200 mg PBE within 48 hours. Subjects followed a low-polyphenol diet for two days prior to oral PBE administration and during urine sample collection. All urine samples were collected within 24 hours. The levels of free and bound ferulic acid in urine were determined using high-performance liquid chromatography-diode array detector (HPLC-DAD). Results showed a close correlation between dietary PBE intake and urinary ferulic acid excretion. Furthermore, the results indicated that a significant portion of ferulic acid was excreted as glucuronide or sulfate after PBE administration, with inter-individual differences ranging from 2% to 20%. The excretion kinetics after 100 mg PBE administration were very similar to those after 200 mg PBE administration. Excretion exhibited a biphasic trend in some subjects. All subjects showed significant but differential ferulic acid excretion levels after PBE supplementation. Therefore, the data suggest that at least a portion of the phenolic components in PBE can be absorbed, metabolized, and eliminated by the human body. Hydroxycinnamate, an intermediate in the phenylpropanoid synthesis pathway, effectively enhances the antioxidant capacity of low-density lipoprotein (LDL), with the effects following those of caffeic acid, ferulic acid, and p-coumaric acid. It remains unclear whether the mechanism of action of ferulic acid as an antioxidant is based on its activity in the aqueous or lipophilic phase. Under optimal water solubility conditions, the partitioning of 14C-labeled ferulic acid in plasma and its components (LDL and albumin-rich fractions) was investigated. Results showed that most ferulic acid bound to the albumin-rich fraction in plasma, but some also partitioned between the LDL and aqueous phases. However, ferulic acid did not bind to the lipid portion of low-density lipoprotein (LDL) particles, indicating that it exerts its antioxidant activity in the aqueous phase. This is particularly noteworthy because the results suggest that ferulic acid inhibits LDL oxidation more effectively than the hydrophilic antioxidant ascorbic acid. The main components of artichoke extract are hydroxycinnamic acid compounds, such as chlorogenic acid, dicaffeoylquinic acid compounds (such as caffeic acid and ferulic acid), and flavonoids, such as luteolin and apigenin glycoside. …Multiple studies have shown the effects of artichoke extract on animal models…Results showed that chlorogenic acid peaked at 6.4 (SD 1.8) ng/mL in plasma 1 hour after administration and disappeared within 2 hours (P<0.05). The peak plasma concentration of total caffeic acid reached 19.5 (SD 6.9) ng/mL within 1 hour, while the plasma concentration of ferulic acid showed a biphasic change, reaching 6.4 (SD 1.5) ng/mL and 8.4 (SD 4.6) ng/mL within 1 hour and 8 hours, respectively. …After 8 hours, the total levels of dihydrocaffeic acid and dihydroferulic acid were significantly increased (P<0.05). Luteolin and apigenin were not detected in circulating plasma.

Metabolism/Metabolites
This study investigated the bioavailability of ferulic acid and its metabolites in plasma and urine of rats after short-term oral administration of 5.15 mg/kg ferulic acid (FA; 3-methoxy-4-hydroxycinnamic acid). Within 30 minutes of ingestion, free ferulic acid, glucuronide conjugates, and sulfonate conjugates were rapidly detected in plasma, reaching peak concentrations. Sulfonate conjugates were the main derivatives (approximately 50%). 1.5 hours after ingestion, the cumulative excretion of total metabolites in urine reached a plateau, with approximately 40% of metabolites excreted via urine. Free ferulic acid recovered in urine accounted for only 4.9 ± 1.5% of the naturally ingested ferulic acid in rats. Glucuronide conjugates and sulfonate conjugates accounted for 0.5 ± 0.3% and 32.7 ± 7.3%, respectively. These results indicate that some of the ferulic acid ingested in the diet is rapidly absorbed and primarily metabolized into sulfonate conjugates before being excreted in urine. Ferulic acid (FA) is a phytochemical commonly found in fruits and vegetables such as tomatoes, sweet corn, and rice bran. Ferulic acid is a product of the metabolism of phenylalanine and tyrosine in plants via the shikimic acid pathway.
It is known that ferulic acid has metabolites in the human body including (2S,3S,4S,5R)-6-[4-[(E)-2-carboxyvinyl]-2-methoxyphenoxy]-3,4,5-trihydroxyoxacyclohexane-2-carboxylic acid.

Interactions
This study evaluated the effects of topical application of curcumin, chlorogenic acid, caffeic acid, and ferulic acid on 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced epidermal ornithine decarboxylase activity, epidermal DNA synthesis, and promotion of skin tumorigenesis in female CD-1 mice. Topical application of 0.5, 1, 3, or 10 μmol curcumin inhibited 5 nmol TPA-induced epidermal ornithine decarboxylase activity by 31%, 46%, 84%, and 98%, respectively. In another study, topical application of 10 μmol curcumin, chlorogenic acid, caffeic acid, or ferulic acid inhibited 5 nmol TPA-induced ornithine decarboxylase activity by 91%, 25%, 42%, and 46%, respectively. Topical application of 10 μmol curcumin in combination with 2 nmol or 5 nmol TPA inhibited TPA-dependent [3H]-thymidine incorporation into epidermal DNA by 49% and 29%, respectively, while lower doses of curcumin had little or no effect. Chlorogenic acid, caffeic acid, and ferulic acid, as inhibitors of TPA-dependent DNA synthesis stimulation, were all less effective than curcumin. In mice pre-injected with 7,12-dimethylbenzo[a]anthracene, topical application of 1, 3, or 10 μmol curcumin twice weekly, along with 5 nmol TPA, for 20 weeks, resulted in a 39%, 77%, and 98% inhibition of TPA-induced tumor numbers per mouse, respectively. Similar treatment with 10 μmol chlorogenic acid, caffeic acid, or ferulic acid in combination with 5 nmol TPA resulted in a 60%, 28%, and 35% inhibition of TPA-induced tumor numbers per mouse, respectively, with higher doses of phenolic acids showing more significant tumor-inhibiting effects. To assess the potential of curcumin in inhibiting arachidonic acid, we investigated the effect of curcumin on arachidonic acid-induced ear edema in mice. Topical application of 3 μmol or 10 μmol curcumin 30 minutes before the application of 1 μmol arachidonic acid inhibited arachidonic acid-induced edema by 33% and 80%, respectively. A series of in vivo experiments were conducted to evaluate the ability of caffeic acid and ferulic acid to reduce UVB-induced skin erythema in healthy volunteers, and the results were monitored by reflectance spectrophotometry. Caffeic acid and ferulic acid dissolved in a saturated aqueous solution at pH 7.2 were shown to significantly protect the skin from UVB-induced erythema. Various synthetic and dietary polyphenols protect mammalian and bacterial cells from cytotoxicity induced by hydrogen peroxide (especially hydrogen peroxide (H₂O₂)). The cytotoxicity of H₂O₂ to Chinese hamster V79 cells was assessed using a colony formation assay. The cytotoxicity and mutagenicity of H₂O₂ against Salmonella TA104 were assessed using the Ames assay. The H₂O₂-induced SOS response was investigated using the SOS chromogenic assay with Escherichia coli PQ37 as a model. The results showed that polyphenolic compounds containing the o-dihydroxy (catechol) structure, such as nordihydroguaiac acid, caffeic acid esters, gallic acid esters, quercetin, and catechins, effectively inhibited H₂O₂-induced cytotoxicity in these assay systems. Conversely, ferulic acid esters and α-tocopherol containing the o-methoxyphenol structure were ineffective, indicating that the o-dihydroxy structure or its equivalent in flavonoids is crucial for protective effects. Many reports have indicated that polyphenolic compounds exhibit pro-oxidative effects in the presence of metal ions. However, these results suggest that they act as antioxidants intracellularly when no metal ions are added to the culture medium. This review describes the radiation injury models induced by soft X-ray irradiation in mice under different conditions, and the protective effects of several substances against these injuries. The radiation injury models in this study included bone marrow death after lethal dose irradiation, skin damage caused by long-wavelength soft X-ray irradiation, and peripheral blood leukopenia after sublethal dose irradiation. Two bioassays were established to evaluate survival rates after lethal dose irradiation and protective efficacy against skin damage induced by soft X-ray irradiation. The protective efficacy of various sulfur compounds, ferulic acid-related compounds, nucleic acid constituent compounds, traditional Chinese medicines, and other traditional Chinese medicines was determined, and several effective drugs were screened. The effective components with radioprotective effects in the methanol extracts of Cnidium monnieri and Aloe vera were isolated. These results indicate that the active components in Cnidium monnieri are ferulic acid and adenosine. The study also evaluated its radioprotective mechanisms, including scavenging reactive oxygen species and protecting DNA and superoxide dismutase from in vitro soft X-ray damage.

Ferulic acid (FA) is an effective free radical scavenger and has been approved as a food additive in some countries for preventing lipid peroxidation.
Sodium ferulate (SF), or sodium 3-methoxy-4-hydroxycinnamate, is an active ingredient in plants such as Angelica sinensis, Cimicifuga foetida, and Ligusticum chuanxiong. It has been used in traditional Chinese medicine and has been approved by the China National Medical Products Administration for the treatment of cardiovascular and cerebrovascular diseases. Sodium ferulate (SF) exhibits antithrombotic, platelet aggregation-inhibiting, and antioxidant activities in both animals and humans. For decades, SF has been widely used in China to treat cardiovascular and cerebrovascular diseases and prevent thrombosis…/Sodium ferulate/
/EXPL THER/ Ligusticum chuanxiong and its active ingredients are used to treat ischemic stroke, a common sudden-onset disease in China. Several injectable formulations, including Ligusticum chuanxiong, ligustrazine, ligustrazine alcohol, and ferulic acid, have undergone clinical and experimental testing. Results show that these drugs are as effective as or even better than control groups (such as papaverine, dextran, and aspirin-dipyridamole). They can improve cerebral microcirculation by inhibiting thrombus formation, platelet aggregation, and blood viscosity.
/EXPL THER/ While more definitive research is needed, some natural remedies show promise in treating hot flashes without the risks associated with traditional therapies. Soy and other phytoestrogens, black cohosh, evening primrose oil, vitamin E, bioflavonoids hesperidin and vitamin C, ferulic acid, acupuncture, and regular aerobic exercise have been shown to be effective in treating hot flashes in menopausal women.
