What actually is cancer?

Cancer is a condition where cells in a specific part of the body grow and reproduce uncontrollably. The cancerous cells can invade and destroy surrounding healthy tissue, including organs. Cancer sometimes begins in one part of the body before spreading to other areas. This process is known as metastasis.

What is camptothecin used for?

Camptothecin, an quinolone alkaloid, is used as a chemotherapeutic agent in the treatment of leukemia (Jones et al., 1997). Camptothecin complexes with type I DNA topoisomerase inhibiting both cleavage and religation reactions of DNA replication thus arresting growth of L.

Where is camptothecin from?

Camptothecin (CPT) (Figure 1A) is a pentacyclic alkaloid that was first isolated from stem wood of Camptotheca acuminata by botanists working in the USDA’s Plant Introduction Division in the mid-1950s [1]. Camptotheca acuminata is a tree native to China and its bark is a recognized Chinese traditional medicine.

Is CPT a drug?

Drug type: CPT-11 is an anti-cancer (“antineoplastic” or “cytotoxic”) chemotherapy drug. CPT-11 is classified as a “plant alkaloid” and “topoisomerase I inhibitor.” (For more detail, see “How this drug works” section below).

• Leukemias. Leukemia is a cancer of the blood.
• Lymphomas.

Is camptothecin a protein?

All of the camptothecin-induced SSB were protein linked, as indicated by the absence of DNA elution under nondeproteinizing conditions. DNA cleavage assays with purified topoisomerase I also indicated that the weaker Sarkosyl detergent fails to trap all of the enzyme-DNA complexes.

When was camptothecin discovered?

Landmark Designation Wall, Mansukh C. Wani, and colleagues discovered two life-saving anticancer agents from natural products. In 1966, they reported the first of these, Camptothecin, from the Chinese tree Camptotheca acuminata. In 1971, they reported the structure of Taxol from the Pacific yew, Taxus brevifolia.
