title: Antineoplastic activity of Holoptelea integrifolia (Roxb.) Planch bark extracts (in vitro).
abstract: Cancer remains the major public health concern with a number of cancer patients relying on chemotherapy as a treatment option. Although, advances in biomedical research have led to increased anticancer agents in recent years, the treatment is not always effective due to resistance, toxicity or other factors. Phytochemicals and their active components isolated from plants have provided diversified effective drugs many of them are currently used against cancer and other diseases. Holoptelea integrifolia (Roxb) Planch (Ulmaceae) is a widely distributed plant in many parts of the world, also grown in gardens of Pakistan. It is an ornamental plant with certain medicinal characteristics due to many valuable and active phyto constituents in various parts of the plant. We looked at in vitro antineoplastic effects of four different extracts, in butanol (BMBU), hexane (BMHx), ethyl acetate (BMET) and chloroform (BMCHF), from bark of Holoptelea integrifolia on small cell lung cancer, breast, prostate, coloretal and hepatocellular cancer cell lines. Plant extracts BMHx and BMET showed significant cytotoxic effects on breast and prostate cancer cells. These preliminary studies are encouraging to proceed further this research in future, regarding the isolation of active phytoconstituents in these extracts as well as its mechanism in chemoprevention and combination anticancer therapy.
