Drug discovery is a time-consuming, costly and high-risk process. It usually takes 10-15 years to develop a new drug. Drug repurposing is an alternative approach of drug discovery. Drug Repurposing (DR) can be defined as a process of identification and discovery of new therapeutic uses, outside the scope of the original pharmacological indication, for already approved drugs.  Cancer is a group of diseases caused by loss of cell cycle control.

These abnormal cells are termed cancer cells, malignant cells, or tumor cells.
