During the past decades, we have witnessed many landmark discoveries and successes in cancer research and therapy,however, cancer is still a major health problem for human beings, and it often physically and emotionally brings pains and difficulties to those living with it. Cancer cells remain undifferentiated (continue to divide, causing more damage, and invading new tissue), lack normal cell signaling responses (loss of contact inhibition and evasion of programmed cell death), contain abnormal changes (genetic abnormalities) in chromatin, have altered energy metabolism, and induce vascularization (ensure a steady supply of oxygen and nutrients).

We carefully select 1990 anti-cancer compounds currently in clinical trial phases based on published literatures and database to form this collection that can be used for high throughput screening and high content screening.
