An Insight into Anticancer Bioactives from (Pomegranate).

Cancer is one of the major reasons for mortality across the globe. Many side-effects are associated with the formulations available in the market, affecting the quality of life of the patients. This has caused the researchers to find an alternative source of medications, such as herbal medicine, showing a promising effect in anticancer treatment; one such source is Pomegranate, which belongs to the family Punicaceae. Punica granatum contains many polyphenols that have antioxidant, antidiabetic, and therapeutic effects in the treatment and management of metabolic and cardiovascular diseases, as well as a favourable effect on anticancer therapy. Polyphenols like punicalin, punicalagin, and ellagic acid are a few of the many compounds responsible for the anticancer activity of pomegranate. Many preparations of pomegranate, such as Pomegranate Juice (PJ), Pomegranate Seed Oil (PSO), Pomegranate peel extract (PoPx), etc. are used in various clinical studies. These polyphenols show anticancer activity by either arresting the cell cycle in the G2/M phase, inducing apoptosis or damaging the DNA of tumor cells. This review explicitly discusses the role and mechanism of bioactives obtained from the pomegranate in the treatment and management of cancer. The chemical structure, properties, and role of pomegranate in the treatment of breast, lung, thyroid, colon, and prostate cancer have been focused on in detail. This review also discusses various targeted drug delivery approaches for tumour treatment as well as patented preparation of pomegranate compounds along with the ongoing clinical trials.
