Novel tricyclic carbazoles 4a-k were synthesized in one-pot employing sydnone derivatives 3a-k as masked hydrazines by the ring transformation in presence of conc. HCl and cyclohexanone. The title compounds were screened for anti-tubercular, anti cancer, DNA cleavage, antioxidant activity. MIC, GI50, LC50, TGI were evaluated. The title compounds have exhibited significant antitubercular, DNA cleavage and antioxidant activities and partial anticancer activity. (C) 2011 Elsevier Masson SAS. All rights reserved.

Ring transformation of sydnone (1a–i) to 1,3,4-oxadiazoline-2-one (2a–i) was carried out using bromine in acetic anhydride. The compounds (2a–i) on heating with hydrazine hydrate gave 1,2,4-triazole (3a–i) in good yields. The structure of these unknown compounds was confirmed by IR, 1H NMR, MS and elemental analysis. Further, these compounds were evaluated for the extent of penetration into biological
使用溴的乙酸酐溶液将sydnone(1a – i)环化为1,3,4-恶二唑啉-2-one(2a – i)。化合物(2A -我)与水合肼加热,得到1,2,4-三唑(3A -我)以良好的收率。这些未知化合物的结构通过IR,1 H NMR,MS和元素分析确认。此外,评估了这些化合物对生物膜的渗透程度(clog P)药物的相似性,最后计算出药物得分。还筛选了标题化合物的降血糖,DNA裂解和抗氧化活性。
