Xanthocidin derivatives as topoisomerase IIα enzymatic inhibitors.
Few studies have examined xanthocidin, a biotic isolated from Streptomyces xanthocidicus in 1966, because its supply is limited. Based on its chemical structure, xanthocidin has the potential to become a lead compound in the production of agrochemicals and anti-cancer drugs; however, it is unstable under both basic and acidic conditions. We recently established the total synthesis of xanthocidi...
متن کامل1H-Benzimidazole derivatives as mammalian DNA topoisomerase I inhibitors.
Benzimidazole is one of the most important heterocyclic groups manifesting various biological properties, such as antibacterial, antifungal, antimicrobial, antiprotozoal and antihelmintic activities. Several benzimidazole derivatives are also active as inhibitors of type I DNA topoisomerases. In this study, three 1H-benzimidazole derivatives with different electronic characteristics at position...
متن کاملDesign, Synthesis and Cytotoxicity Evaluation of New 2-Aryl-5,6-Dihydropyrrolo[2, 1-a]Isoquinoline Derivatives as Topoisomerase Inhibitors
Two set of 2-aryl-5,6-dihydropyrrolo[2,1-a] isoquinolines were designed and synthesized to evaluate their biological activities as topoisomerase inhibitors. Cytotoxic activity of the synthesized compounds 4a-e and 7a-d was assessed against several human cancer cell lines, including MCF-7 (breast cancer cell), HepG2 (liver hepatocellular cells), A549 (adenocarcinomic human alveolar basal epithel...
متن کاملCyclometalated platinum(II) complexes as topoisomerase IIα poisons.
A platinum(II)-based major groove binder [Pt(II)(C^N)(C≡NR)(2)](+) (HC^N = 2-phenylpyridine (phpy), R = 2-naphthyl) was identified as a potent human topoisomerase IIα poison. It stabilizes the covalent TopoIIα-DNA cleavage complex and induces cancer cell death with potency significantly higher than the widely clinically used TopoIIα poison Vp-16.
متن کاملTopoisomerase IIα as a prognostic factor in pituitary tumors.
INTRODUCTION There is an ongoing search for markers of pituitary tumor proliferation and progression that could facilitate further treatment and patient monitoring. OBJECTIVES We studied topoisomerase IIα (topo IIα) expression in different types of pituitary adenomas to evaluate its prognostic value. PATIENTS AND METHODS In a retrospective study of 60 patients (mean age, 46.7 ±17.6 y) who u...
