  Synthesis and anticancer activity of 2-amino-8-chloro-5,5-dioxo[1,2,4]triazolo[2,3- b ][1,4,2]benzodithiazine derivatives

  摘要：

  A new series of 1-(6-chloro- 1, 1 -dioxo- 1,4,2-benzodithiazin-3-yl)-4-arylsemicarbazides (4-16) were obtained. Intramolecular ring closure in semicarbazides 4-16 upon treatment with phosphorus oxychloride resulted in the formation of 2-amino-8-chloro-5,5-dioxo[1,2,4]triazolo[2,3-b][1,4,2]benzodithiazines 17-29 with potential antitumor activity. The structures of these compounds were confirmed on the basis of elemental analysis, spectral data and X-ray analysis. Compounds 17-29 were screened at the US National Cancer Institute (NCI) for their activities against a panel of 59 tumor cell lines, and relationships between structure and antitumor activity in vitro are discussed. The benzodithiazines 18, 19, 23, 28 and 29 were inactive, whereas the other compounds exhibited reasonable activity against numerous human tumor cell lines. The prominent compound 17 showed significant activity against the leukemia SR cell line (log GI(50)= -7.67, log TGI= -6.90 and log LC50=-4.77). (C) 2003 Elsevier Science Ltd. All rights reserved.

  An efficient method for the synthesis of structurally diverse 4-aryl-3-(tri/difluoromethyl)-1H-1,2,4-triazol-5(4H)-ones through the cyclization of hydrazinecarboxamides with tri/difluoroacetic anhydride is presented.

• Design and synthesis of novel triazole antifungal derivatives by structure-based bioisosterism

  The incidence of life-threatening fungal infections is increasing dramatically. In an attempt to develop novel antifungal agents, our previously synthesized phenoxyalkylpiperazine triazole derivatives were used as lead structures for further optimization. By means of structure-based bioisosterism, triazolone was used as a new bioisostere of oxygen atom. This type of bioisosteric replacement can improve the water solubility without loss of hydrogen-bonding interaction with the target enzyme. A series of triazolone-containing triazoles were rationally designed and synthesized. As compared with fluconazole, several compounds showed higher antifungal activity with broader spectrum, suggesting their potential for further evaluations. (C) 2011 Elsevier Masson SAS.
