Anti-Proliferative and Apoptosis-Inducing Effects of Camptothecin-20(s)-O-(2-pyrazolyl-1)acetic Ester in Human Breast Tumor MCF-7 Cells

Autor: Chu Chu, Jialin Xu, Dongping Cheng, Xingnuo Li, Shengqiang Tong, Jizong Yan, Qingyong Li

Publikováno v: Molecules, Vol 19, Iss 4, Pp 4941-4955 (2014)

Camptothecin-20(s)-O-(2-pyrazolyl-1)acetic ester (CPT6) is a novel semi-synthetic analog of camptothecin. In a previous report, CPT6 possessed higher cytotoxic activity in vitro towards human breast tumor MCF-7 cells than topotecan. In this study, th

Synthesis of Isoquinoline-1,3(2H,4H)-diones by Visible-Light-Mediated Cyclization of Acryloylbenzamides with Alkylboronic Acids, Arylsulfonyl Hydrazides and Oxime Esters

Autor: Xiaoliang Xu, Dongping Cheng, Jiahui Fu, Xingxing Cai, Yihuo Liu, Jinghua Li

Publikováno v: Synthesis. 54:2707-2723

An efficient visible-light-mediated tandem reaction of acryloylbenzamides with alkylboronic acids, arylsulfonyl hydrazides and oxime esters has been developed. The reaction proceeds via radical addition and cyclization to give various isoquinoline-

Cu(OTf)2/TBHP/O2-Mediated Tandem Oxidative Reaction: Easy Access to Benzopyrano[4,3-b]pyridines

Autor: Xiaoliang Xu, Jing-Hua Li, Dongping Cheng, Hongjiao Yang, Hongshuang Xia, Huafang Gu

Publikováno v: Synthesis.

An effective tandem reaction of 4-aminocoumarins and 1,3-diarylpropenes mediated by Cu(OTf)2/TBHP (tert-butyl hydroperoxide)/O2 that provides various benzopyrano[4,3-b]pyridines in moderate to good yields is disclosed. The reaction proceeds through o
