Efecto a nivel celular y molecular de agentes antitumorales Cellular and molecular effect of antitumor agents

Cellular and molecular biology is a research field with high impact and fast growth; it becomes essential for the development of new chemotherapeutic agents with low toxicity, particularly against cancer. Although chemotherapy era began in the 40’s, it has been necessary to development new antitumoral therapies that produce appropriate treatment for each patient and kind of tumor. Therefore, identifying cellular and molecular components involved in the process of carcinogenesis for development of chemotherapeutic agents involved in restoration or selective destruction of cancer cells is necessary. Currently, it has been shown that certain drugs such as antibiotics (tetracycline, sulfonamide and b-lactams) and others chemicals compounds (quinoxalines) that are used for another purpose showed anticancer effects with antiproliferative and inhibitory activity. Therefore these could be a new option for pharmacological treatment of cancer.
