2-Triazenoazaindoles: Α novel class of triazenes inducing transcriptional down-regulation of EGFR and HER-2 in human pancreatic cancer cells
2012
Pancreatic cancer is a complex malignancy arising from the accumulation of genetic and epigenetic defects in the affected cells. Standard chemotherapy for patients with advanced disease shows only modest effects and is associated with considerable toxicity. Overexpression or aberrant activation of members of the epidermal growth factor receptor tyrosine kinase family, which includes EGFR and HER-2, occurs frequently and is associated with multiple drug resistance and decreased patient survival. In this study, we have investigated the therapeutic potential of AS104, a novel compound of the triazene class, with potential inhibitory effects on EGFR. We found that treatment of cells with AS104 …
Synthesis of Triazenoazaindoles: a New Class of Triazenes with Antitumor Activity
2011
Despite improvements in the treatment and prevention of cancer, the number of new diagnoses continues to rise; this has fuelled substantial interest in the development of new and effective chemotherapeutic agents. Compounds of the triazene class, such as dacarbazine, have been used in the clinical management of many cancer types including brain, leukemia, and melanoma. A new compound class bearing a triazenoazaindole scaffold was synthesized with the aim of identifying new antiproliferative agents. Compounds 5 a-g and 6 a-c were screened against a panel of human tumor cell lines, and two of them, 5 e and 5 f, showed cytotoxicity (GI(50) range: 2.2-8.2 μM) in all cell lines. These two compou…
