Medicinal Chemistry of Natural Anti-Skin Cancer Agents: An Evidence-Based Literature Review

Globally, the incidence and prevalence of skin cancer have increased. Skin cancers involve an abnormal growth of cells. Skin cancers are classified into melanoma and nonmelanoma skin cancer (NMSC), and NMSC is further classified as squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). In the present narrative review, we searched databases, such as PubMed, Scopus, and Google Scholar, to retrieve the relevant articles. The ideal selection of therapeutic options depends on the anatomical location, genetic composition, different tumor stages, the individual's age, and general health conditions. Various chemotherapeutic options are available for effective treatment, but there are various side effects of the drugs. Natural products (NPs) may be used as supplements. NPs can potentiate apoptosis, decrease cell growth, and prevent metastasis. They are also safe and effective. The present review summarizes the use of natural products, such as Aloe vera, eggplant, frankincense, milk thistle, turmeric, black raspberry, mistletoe, burdock root, Dong Quai, black salve, astragalus, Solanum sodomaeum, Calendula officinalis, Melaleuca alternifolia, Hypericum perforatum, Withania somnifera, Polypodium leucotomos, Rosmarinus officinalis, Alpinia galangal, hypericin, tea, coffee, genistein, grape seed, and silymarin. Larger clinical trials are needed to explore the safety profile of various natural products that have proven effective against skin cancer.
