Baicalein, a natural flavonoid in gastrointestinal cancers treatment: recent trends and future perspectives.

Gastrointestinal cancer is a malignant condition of the gastrointestinal tract (GI) which affect multi-organs of digestive system, such as esophagus, stomach, biliary system, pancreas, small intestine, large intestine, rectum, and anus. Gastrointestinal cancer is a 5th most common malignant cancer and 4th major cause in cancer-related mortality rate. Various significant facilities are available that have reduced the radio-resistance, chemo-resistance, and their adverse side effects. However, there are serious side effects associated with chemical and radiations during the process. Baicalein is a natural flavonoid extracted from dried roots of Scutellaria baicalensis, showing anti-cancerous property. It is also participating in inhibiting metastasis, accelerating apoptosis and elevating autophagy through inhibition of inflammation and cell proliferation. In this review, we have focused on Chemistry and pharmacokinetics of Baicalein for drug designing and clinical applications majorly in gastrointestinal cancer. Moreover, various types of cancer related to gastrointestinal, role of nanotechnology, and its synergism for reducing cancer are also discussed. Thus, the review would be beneficial to explore the role of baicalein against gastrointestinal cancer treatment.
