Antibiotic Drugs For Cancer Treatment

An antibiotic is a chemical made by a microbe that antagonizes the growth of other cells,  While classical antibiotics like penicillin attack other microbes, the chemotherapy medicines that are called antibiotics interfere with the DNA and its replication.  In this they are like many chemotherapy medicines. The origins of the antibiotics are microorganisms (bacteria or fungi) but once they get discovered as effective drugs, their chemical structure is elucidated and they are made by chemical synthesis without biotechnology.

Antibiotic medicines kill malignant cells by fragmenting the DNA in the cell nucleus and by oxidizing critical compounds the cells need.   They are not cell-cycle specific. Antibiotics are used against leukemia, testicular cancer, and sarcomas.
