ABSTRACT Nonmelanoma skin cancer (NMSC) represents the most prevalent form of skin cancer globally, with basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) being the most common types. The search for effective chemopreventive and therapeutic agents has led to the exploration of natural compounds, among which resveratrol (RES), a polyphenolic phytoalexin found in grapes, berries, peanuts, and red wine, has garnered significant attention. This comprehensive review aims to elucidate the effects of RES on NMSC, focusing on its mechanisms of action, efficacy in preclinical studies, and potential as a chemopreventive and therapeutic agent. RES exhibits promising chemopreventive and antineoplastic capabilities against NMSC through various mechanisms, including the induction of apoptosis, inhibition of cell proliferation, modulation of oxidative stress, and anti‐inflammatory activities. Studies have demonstrated that RES can significantly enhance the effectiveness of traditional chemotherapeutic agents, such as 5‐fluorouracil (5‐FU), by inhibiting cellular proliferation and inducing apoptosis in cancerous cells. Furthermore, resveratrol's antioxidant properties may mitigate the impact of reactive oxygen species (ROS) triggered by UV exposure, thus reducing DNA damage and mutations associated with skin cancer development. In vitro and in vivo experiments have shown that RES can effectively hinder the growth and spread of various tumor cell types, including human cutaneous SCC A431 cells, and induce apoptosis. The development of advanced delivery systems, such as nanostructured lipid carriers and liposomes, has been recognized for their potential to enhance the therapeutic effects of RES, particularly its anticancer properties. In conclusion, RES presents a viable candidate for the prevention and treatment of NMSC, owing to its multifaceted mechanisms of action, including its ability to regulate oxidative stress, trigger apoptosis, and inhibit proliferation. However, further clinical studies are required to fully understand its effectiveness and safety in humans, as well as to optimize delivery methods for improved bioavailability and therapeutic outcomes.

Parkinson's disease (PD) is a chronic and progressive neurological disorder characterized by the degeneration of dopaminergic neurons in the substantia nigra pars compacta (SNc). The pathogenesis of PD is strongly related to mitochondrial dysfunction, oxidative stress, and neuroinflammation. This indicates that PD can be treated with anti-oxidative substitutes and anti-inflammatory compounds. The neuroprotective and anti-inflammatory effects of peroxisome proliferator-activated receptor γ (PPAR-γ) agonists decrease cell death and halt the increase in neurodegeneration, which is why they have been given a lot of importance in research. Antidiabetic and anti-inflammatory effects have been observed to be generated by pioglitazone (PG), a selective peroxisome proliferator-activated receptor γ (PPAR-γ) agonist that regulates neural plasticity in various neurodegenerative disorders. The neuroprotective and anti-inflammatory effects of PG are assessed in this article. It was found that the patients with DM who received PG treatment were noticeably at a lower risk of PD. However, some clinical studies have not proven a strong link between the therapeutic effects of PG on PD. As per suggestions of preclinical studies, the therapeutic effects of PG treatment include; increased life expectancy of neurons, decreased oxidative stress, halted microglial activity, lower inflammation (reduced NF-κB, COX-2, and iNOS), reduced mitochondrial dysfunction, rise in motor function (motor agility) and non-motor function (lowered cognitive dysfunction). In conclusion, we determined that PG exerts neuroprotective and anti-inflammatory effects in PD models and it can be considered a potential therapeutic candidate for PD., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)
