Description

COMPOSITION FOR TREATING CANCER AND METHOD OF
SYNTHESIZING THE SAME
A) TECHNICAL FIELD OF INVENTION
[001] The present invention generally relates to a composition for treating cancer. The present invention more particularly relates to a composition for treating cancer comprising berberine as the main active ingredient. The present invention also relates to a method of preparing the composition and a therapeutically suitable formulation that is to be given to the patients.
B) BACKGROUND OF INVENTION
[002] The berberine is a quaternary ammonium salt derived from the protoberberine group of isoquinoline alkaloids. The berberine is found in various species of plant with genus Berberis. Some of the species of Berberis containing berberine are Berberis aquifolium, Berberis vulgaris and Berberis aristata. The berberine is also found in plants like Hydrastis canadensis, Xanthorhiza simplicissima, Phellodendron amurense, Coptis chinensis, Tinospora cordifolia, Argemone mexicana and Eschscholzia californica. The berberine is usually found in the roots, rhizomes, stems and bark of these trees. The berberis is a plant found mostly in South America, Africa and Asia. Few species are found in Europe and North America also.
[003] Traditionally, berberine is used as a medicine or dietary supplement. The berberine has shown some activity against fungal infections caused by Candida albicans, yeast, parasites and bacterial/viral infections. The berberine also possesses antibiotic properties.
[004] The berberine has various mechanisms of action, but tends to be known as an AMPK activator. Alongside AMPK activation berberine also exerts anti-inflammatory effects. The berberine is also benefits intestinal health and integrity. The berberine acts in synergism with anti-depressant medications, has lipids and cholesterol lowering effects and is highly antidiabetic.
[005] Apart from the above properties, berberine also possesses anti-cancer activities. The berberine has been used in synergism with many other anti-cancer agents where berberine enhances the anti-cancer activities. But still these compositions fail to provide an effective and patient complaint formulations. Some of these formulations cannot be taken orally and the active agents of these compositions are not freely available.
[006] Hence there is a need to develop a pharmaceutical formulation possessing anti-cancer activity comprising berberine as active pharmaceutical ingredient. There is also a need to provide an anti-cancer formulation that can be taken orally.
[007] The above mentioned shortcomings, disadvantages and problems are addressed herein, as detailed below.
C) OBJECTS OF THE INVENTION
[008] The primary object of the present invention is to provide a pharmaceutical composition for treating cancer.
[009] Another object of the present invention is to provide a pharmaceutical composition for treating cancer comprising berberine along with other additives.
[0010] Yet another object of the present invention is to provide an-easy- administer anti-cancer formulation.
