Description:
Lycopene is the pigment principally responsible for the characteristic deep-red color of ripe tomato fruits and tomato products. Lycopene is an antioxidant scavenger, hypolipaemic agent, inhibitor of pro-inflammatory and pro-thrombotic factors, thus potentially of benefit in cardiovascular disease (CVD). Lycopene may play a role in the prevention of Renal cell carcinoma, it also may play a role against obesity-related complications.

Lycopene inhibits cyclic strain-induced endothelin-1 expression through the suppression of reactive oxygen species generation and induction of heme oxygenase-1 in human umbilical vein endothelial cells.
Lycopene is the most potent active antioxidant among the major carotenoids, and its use has been associated with a reduced risk for cardiovascular disease (CVD). This study investigated the effects of Lycopene on cyclic strain-induced ET-1 gene expression in human umbilical vein endothelial cells (HUVECs) and identified the signal transduction pathways that are involved in this process.
METHODS AND RESULTS:
Cultured HUVECs were exposed to cyclic strain (20% in length, 1 Hz) in the presence or absence of Lycopene. Lycopene inhibited strain-induced ET-1 expression through the suppression of reactive oxygen species (ROS) generation through attenuation of p22(phox) mRNA expression and NAD(P)H oxidase activity. Furthermore, Lycopene inhibited strain-induced ET-1 secretion by reducing ROS-mediated extrace-llular signal-regulated kinase (ERK) phosphorylation. Conversely, Lycopene treatment enhanced heme oxygenase-1 (HO-1) gene expression through the activation of phosphoinositide 3-kinase (PI3K)/Akt pathway, followed by induction of the nuclear factor erythroid 2-related factor 2 (Nrf2) nuclear translocation; in addition, HO-1 silencing partially inhibited the repressive effects of Lycopene on strain-induced ET-1 expression.
CONCLUSIONS:
In summary, our study showed, for the first time, that Lycopene inhibits cyclic strain-induced ET-1 gene expression through the suppression of ROS generation and induction of HO-1 in HUVECs.Therefore, this study provides new valuable insight into the molecular pathways that may contribute to the proposed beneficial effects of Lycopene on the cardiovascular system.

Effect of high power low frequency ultrasound processing on the stability of lycopene.
The stability of Lycopene was evaluated after application of high power low frequency ultrasound.
METHODS AND RESULTS:
The study was carried out on a solution containing pure Lycopene to evaluate the direct effect of ultrasound on Lycopene and on tomato purée to evaluate the direct and indirect effects of ultrasound application within a food matrix. Power densities ranging from 55 to 5000 W/L and temperatures ranging from 23°C (ambient) to 60°C were evaluated. The experiments on pure Lycopene showed that the application of ultrasound did not have any direct effect over Lycopene. However, the retention of Lycopene in tomato puree has decreased indicating an indirect effect on Lycopene stability caused by high concentration of hydrogen peroxide and the activation of peroxidase enzymes leading to the reduction of ascorbic acid and its regenerative action towards Lycopene.

Lycopene and cardiovascular diseases: an update.
Cardiovascular disease (CVD) is the leading cause of death in Western societies and accounts for up to a third of all deaths worldwide. In comparison to the Northern European or other Western countries, the Mediterranean area has lower rates of mortality from cardiovascular diseases and cancer, and this is attributed, at least in part, to the so-called Mediterranean diet, which is rich in plantderived bioactive phytochemicals. Identification of the active constituents of the Mediterranean diet is therefore crucial to the formulation of appropriate dietary guidelines.
METHODS AND RESULTS:
Lycopene is a natural carotenoid found in tomato, an essential component of the Mediterranean diet, which, although belonging to the carotenoid family, does not have pro-vitamin A activity but many other biochemical functions as an antioxidant scavenger, hypolipaemic agent, inhibitor of pro-inflammatory and pro-thrombotic factors, thus potentially of benefit in CVD. In particular, the review intends to conduct a systematic analysis of the literature (epidemiological studies and interventional trials) in order to critically evaluate the association between Lycopene (or tomato products) supplementation and cardiovascular diseases and/or cardiovascular disease risk factors progression, and to prepare provision of evidence-based guidelines for patients and clinicians. Several reports have appeared in support of the role of Lycopene in the prevention of CVD, mostly based on epidemiological studies showing a dose-response relationship between Lycopene and CVD. A less clear and more complex picture emerges from the interventional trials, where several works have reported conflicting results.
CONCLUSIONS:
Although many aspects of Lycopene in vivo metabolism, functions and clinical indications remain to be clarified, supplementation of low doses of Lycopene has been already suggested as a preventive measure for contrasting and ameliorating many aspects of CVD.

Lycopene, CAS number 502-65-8, is a natural carotenoid widely found in tomatoes and their products, as well as in red fruits and vegetables. As a non-pigmented lipid-soluble compound, lycopene has attracted widespread attention in the field of natural product pharmacology in recent years due to its powerful antioxidant capacity and potential health benefits. Numerous epidemiological and experimental studies have shown that lycopene demonstrates significant biological activity in preventing and adjuvanting the treatment of various chronic diseases, especially tumor conditions such as prostate cancer. This paper will systematically review the chemical structure and physicochemical properties of lycopene, its plant origin and extraction methods, pharmacological activity and mechanism of action, and, combined with its efficacy evaluation and pharmacokinetic characteristics, explore its clinical application prospects and future research directions.
Lycopene belongs to the carotenoid family with an open-chain polyunsaturated olefin structure, molecular formula C40H56, and molecular weight 536.8880. Its structural feature is a long-chain polyene skeleton composed of 13 conjugated double bonds, giving it excellent light absorption and antioxidant properties. Lycopene is non-polar, with a TPSA (topological pole surface area) of 0, indicating a lack of polar groups and resulting in extremely low water solubility (0.0000), while the LogP reaches as high as 12.2143, indicating strong lipophilic and lipophilic properties. This physicochemical property allows lycopene to be mainly distributed in lipid-rich tissues in the body, especially cell membranes and lipid droplets.
Additionally, lycopene has a high ability to penetrate the blood-brain barrier, suggesting its potential to play a role in neurological diseases. The hERG channel inhibition test was negative, indicating a low risk of cardiotoxicity. The Ames-induced mutagenic test scored 0.3, indicating low genotoxicity risk and good safety.
Lycopene is mainly found in tomatoes (Solanum lycopersicum) and their processed products, such as ketchup, tomato juice, and tomato powder. In addition, red fruits and vegetables such as watermelon, red grapefruit, and red chili peppers also contain certain amounts of lycopene. During tomato maturation, lycopene content increases significantly as chlorophyll degrades and carotenoids accumulate.
Traditional extraction methods mainly use organic solvents such as ethanol, hexane, and acetone for extraction and then purification through liquid-liquid partitioning and column chromatography. In recent years, supercritical CO2 extraction technology has become the mainstream method for extracting lycopene due to its green and environmentally friendly nature, solvent-free residue, and efficient extraction efficiency. In addition, emerging technologies such as ultrasound-assisted extraction and microwave-assisted extraction are also widely used to improve extraction efficiency and purity.
During extraction, attention must be paid to lycopene's sensitivity to light, heat, and oxygen. Measures such as light protection, low temperatures, and inert gas protection are often used to prevent degradation and isomerization.
The pharmacological activity of lycopene is mainly reflected in its powerful antioxidant, anti-inflammatory, anti-tumor, and cardiovascular protective effects. Its antioxidant capacity comes from its multiple conjugated double bond structure, which effectively scavenges free radicals, inhibits lipid peroxidation, and protects cells from oxidative damage.
Prostate cancer is the most in-depth area in lycopene research. A large number of in vivo and in vivo experiments and epidemiological studies have shown that lycopene intake is significantly associated with a reduced incidence of prostate cancer. Its anti-tumor mechanisms involve inducing cancer cell apoptosis, inhibiting cell proliferation, blocking tumor angiogenesis, and regulating the tumor microenvironment.
Lycopene can downregulate the expression of various inflammatory mediators, such as tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6), alleviating chronic inflammatory states and thus exerting protective effects.
Lycopene demonstrates good cardiovascular protective potential by reducing LDL oxidation, improving vascular endothelial function, and regulating lipid metabolism, thereby lowering the risk of atherosclerosis.
In addition, lycopene also demonstrates certain pharmacological activities in skin protection, prevention and treatment of diabetic complications, and neuroprotection.
The biological activity of lycopene is mainly realized by regulating multiple signaling pathways and key molecular targets. For prostate cancer, the main targets of lycopene's action include:
Through the synergistic regulation of these targets, lycopene can effectively inhibit the growth and metastasis of prostate cancer cells, promote apoptosis, and improve the tumor microenvironment.
The high lipid solubility (LogP 12.2143) and zero polarity (TPSA 0) of lycopene lead to extremely poor water solubility, affecting oral bioavailability. Its absorption in the gastrointestinal tract depends on lipid mediators, and when consumed together with dietary fats, absorption rates can be significantly improved. Lycopene is mainly distributed in adipose tissue, the liver, and the prostate, and it has good blood-brain barrier penetration ability.
In terms of metabolism, lycopene is mainly metabolized by the hepatic cytochrome P450 enzyme system, with some metabolites having biological activity. The main excretion routes are bile and feces, with the kidneys excreting less secretion.
Safety evaluations showed that lycopene had no significant hERG channel inhibition, had a low genotoxicity risk, and was safe for long-term intake. Nevertheless, due to its strong lipid solubility and limited bioavailability, formulation development needs to focus on addressing its solubility and stability issues.
Thanks to its remarkable antioxidant and antitumor activities, lycopene shows broad application prospects in the prevention and adjuvant treatment of prostate cancer. Multiple clinical trials have shown that long-term lycopene supplementation can reduce the risk of prostate cancer and improve patients' quality of life. Moreover, lycopene, as a natural product, has fewer side effects and is suitable for long-term use.
Future research should focus on:
As a natural carotenoid, lycopene has become a hot topic in pharmacological research of natural products due to its unique chemical structure and remarkable biological activity. Its potential for prevention and treatment in various diseases such as prostate cancer has been preliminarily validated. Despite challenges such as low bioavailability and poor stability, lycopene is expected to become a safe and effective natural drug or adjunct therapy through modern pharmaceutical formulation technology and molecular mechanism research. In the future, interdisciplinary in-depth research will drive lycopene from the laboratory to clinical practice, benefiting more patients.
