Synthesis and anticancer activity of 2,4-disubstituted furo[3,2-b]indole derivatives
摘要:
We synthesized and evaluated a series of 2,4-disubstituted furo[3,2-b]indole derivatives for anticancer activity and established the structure activity relationships (SARs) of these compounds. Among all tested compounds, we found (5-((2-(hydroxymethyl)-4H-furo[3,2-b]indol-4-yl)methyl)furan-2-yl) methanol (10a) to be the most promising agent. In screening against NCI-60 human tumor cell lines, 10a exhibited highly selective anticancer activity and significant inhibitory activity against A498 renal cancer cells. Our COMPARE analysis results suggest that the 10a fingerprint is similar to that of NSC-754549, which is an isostere of YC-1. We further confirmed the significant antitumor activity of compound 10a with tests in the A498 xenograft nude mice model. Therefore, compound 10a should be further developed as a new drug candidate for treating renal cancer. (C) 2013 Elsevier Masson SAS. All rights reserved.
4 H-呋喃并[3,2- b ]吲哚衍生物的合成。III †。4 H-呋喃并[3,2 - b ]吲哚-2-羧酸衍生物的制备
摘要:
甲基或乙基4 H-呋喃[3,2 - b ]吲哚-2-羧酸酯(Va,b)是通过对5-(2-硝基苯基)-2-呋喃甲酸甲酯或乙基(IIIa,b)脱氧并进行热解制备的5-(2-叠氮苯基)-2-糠酸酯的甲基或乙基(VIIIa,b)。4 H-呋喃[3,2 - b ]吲哚-2-羧氯(X)与四氢呋喃[3,2 - b ]吲哚-2-羧酰氯(X)反应制得4 H-呋喃[3,2 - b ]吲哚-2-羧酸酰胺(XIa-h)适当的胺。
