TargetingG-quadruplex structures is currently viewed as a promising anticancer strategy. Searching for potent and selective G-quadruplex binders, here we describe a small series of new monohydrazone derivatives designed as analogues of a lead which was proved to stabilize G-quadruplex structures and increase R loop levels in human cancer cells. To investigate the G-quadruplex binding properties of

A metal-free polychloromethyl radical-initiated cyclization of unactivated alkenes was developed using CH2Cl2 and CHCl3 as the di- and trichloromethyl radical sources. Variously substituted N-allyl-indoles were successfully transformed into the corresponding C2-(di- and trichloromethyl) pyrrolo[1,2-a]indoles in moderate to good yields. This reaction has a broad substrate scope and good functional group

chromone-pyrazole, indole-pyrimidine, indole-indolinone and indole-pyrazole moieties. Evaluation of these compounds for tumor growth inhibitory activities over 60 human tumor cell lines provided highly efficacious compounds 15, 41, 43, 66, 69, and 72 with an average GI50 over all the 60 human tumor cell lines as 3.2 μM, 3.1 μM, 1.7 μM, 2.6 μM, 50.1 μM and 2.0 μM, respectively.
