Publication date: December 2017 Source:Phytochemistry Letters, Volume 22 Author(s): Weina Jiang, Yingyue Bu, Mioko Kawaguchi, Hiroki Osada, Masayuki Fukuoka, Hajime Uchida, Ryuichi Watanabe, Toshiyuki Suzuki, Hiroshi Nagai Chemical analysis of the hydrophilic fraction from marine cyanobacterium Moorea producens extracts led to the isolation of five new indole derivatives (1-5). So far, 2-formyl-4,5,6,7-tetrahydroindole has been reported only for 6 from the nature, consequently compounds 1-5 were the second representatives of this class. Cytotoxicity, diatom growth inhibition, and antibacterial activity tests for compounds 1-5 showed no bioactivity at the concentration tested. Graphical abstract
