title: Gentisides A and B, two new neuritogenic compounds from the traditional Chinese medicine Gentiana rigescens Franch.
abstract: Two new alkyl 2,3-dihydroxybenzoates, gentisides A and B, were isolated from the traditional Chinese medicine Gentiana rigescens Franch. Their structures and stereochemistry were elucidated by spectroscopic methods and chemical derivatization. These compounds showed a significant neuritogenic activity at 30 microM against PC12 cells that was comparable to that seen for the best nerve growth factor (NGF) concentration of 40 ng/mL. Gentisides A and B showed parallel activity, indicating that the observed structural difference at the end of their alkyl chain did not affect neuritogenic activity.
