  • Mitomycin C undergoes reduction of its quinone function to generate a bifunctional DNA alkylating agent. It is a broadly active antineoplastic agent with a number of unpredictable toxicities, including delayed bronchospasm 12–14 h after dosing and a chronic pulmonary fibrosis syndrome more frequent at doses of 50–60 mg/m2. Cardiomyopathy has been described, particularly in a setting of prior radiation therapy. A hemolytic/uremic syndrome carries an ultimate mortality rate of 25–50% and is poorly treated by conventional component support and exchange transfusion.

  • While researching this book, I came across a letter in the journal Nature asking for caution in the current trend for the use of humorous nomenclature for newly discovered genes1, the author referring to the tumour suppressor gene Pokemon, which I have briefly described in Chapter 4.

  • Chemotherapy Unlike many other epithelial malignancies, breast cancer responds to multiple chemotherapeutic agents, including anthracyclines, alkylating agents, taxanes, and antimetabolites. Multiple combinations of these agents have been found to improve response rates somewhat, but they have had little effect on duration of response or survival. The choice among multidrug combinations frequently depends on whether adjuvant chemotherapy was administered and, if so, what type.

  • A young woman confronted with a diagnosis of systemic lupus erythematosus (SLE) can expect lifelong complications arising from the disease itself, as well as the therapies used to treat this condition. About 50–70 per cent of SLE patients experience inflammation of the kidneys. As such, the young woman can expect to be treated with high doses of corticosteroids, often accompanied by the alkylating agent cyclophosphamide.

  • The benzoacronycine derivative, S23906-1, was character-ized recently as a novel potent antitumor agent through alkylation of theN2 positionof guanines inDNA.We show here that its reactivity towards DNA can be modulated by glutathione (GSH). The formation of covalent adducts between GSH and S23906-1 was evidenced by EI-MS, and the use of different GSH derivatives, amino acids and dipeptides revealed that the cysteine thiol group is absolutely required for complex formation because glutathione disul-fide (GSSG) and other S-blocked derivatives failed to react covalently with S23906-1. ...

  • From the 3-acetylaminoindan-1-one obtained during the course of our work, we studied the synthesis of novel indanone derivatives as new antitumor agents, by acidic hydrolysis of the acetamide group, diazotisation and alkylation of the amino group and bromination of the cyclopentanic methylene group.
