- Abstract
- A new indole alkaloid, pulveratinol (1), and two new anthranilic acid derivatives (2 and 3) were isolated from Indigo Pulverata Levis, together with 12 known compounds (4-15). The structures of the new compounds (1-3) were determined through spectroscopic methods. The absolute configuration of 1 was confirmed further by electronic circular dichroism (ECD) data analysis and computational method with advanced statistics (DP4). All isolated compounds (1-15) were evaluated for their potential neuroprotective effects through induction of nerve growth factor (NGF) in C6 glioma cells. (C) 2018 Published by Elsevier Ltd.
