We have previously designed and synthesized small-molecule inhibitors that reduce Vibrio cholerae virulence in vitro by targeting the transcription factor ToxT. Here we report the synthesis and biological activity of derivatives of our previous bicyclic, fatty acid-like inhibitors. All of the synthesized derivatives show antivirulence activity in vitro. For the most potent compounds, a concentration of 5 μM completely inhibited ToxT-mediated tcpA expression as measured in the β-galactosidase assay. One indole compound, 3-(1-butyl-1H-indol-7-yl)propanoic acid (8), was also effective at inhibiting intestinal colonization in the infant mouse. These modified compounds may serve as good candidates for further anti-cholera drug development.

C7?H-functionalized indoles are ubiquitous structural units of biological and pharmaceutical compounds for numerous antiviral agents against SARS-CoV or HIV-1. Thus, achieving site-selective functionalizations of the C7?H position of indoles, while discri

An efficient rhodium-catalyzed method for C-H olefination at the C7 position of indoles has been developed. The N-imino directing group was shown to be crucial for high regioselectivity and reactivity of the metal catalyst. The utility of this protocol was further demonstrated through a concise, four-step synthesis of pyroquilon from indole.

The parent pyrrolo[3,2,1-ij]quinolin-4-one and pyrrolo[ 3,2,1-ij]quinolin-6-one ring systems were made by pyrolysis of appropriate acrylates. In the first case, the cyclisation was effected by flash vacuum pyrolysis (FVP) at 950 °C, in the second case a cyclisation-dehydrogenation was carried out in one step by FVP over a tungsten trioxide catalyst at 525 °C.

Sulfur-Directed C7-Selective Alkenylation of Indoles under Rhodium Catalysis

Regioselective direct functionalization of an indole benzenoid fragment has been a significant challenge because of its inherently lower reactivity. In this report, we introduce a Rh-catalyzed C7-selective alkenylation of indole derivatives using a new sulfur directing group N-SCy. A notable feature of this system is that the directing group is readily installed to the indoles and easily removed after the catalysis under mild conditions.
