Stereoselective catalysts for the Pictet–Spenglerreaction of tryptamines and aldehydes may allow a simple and fast approach to chiral 1‐substituted tetrahydro‐β‐carbolines. Although biocatalysts have previously been employed for the Pictet–Spenglerreaction, not a single one accepts benzaldehyde and its substituted derivatives. To address this challenge, a combination of substrate walking and transfer of beneficial

fumitremorgin C (FTC), Ko143, and the alkaloid harmine, which contain a tetrahydro-β-carboline or β-carboline backbone, respectively. However, toxicity and or instability prevent their use in vivo. Therefore, there is a need for further potent inhibitors. We synthesized and pharmacologically investigated 37 tetrahydro-β-carbolinederivatives. The inhibitory activity of two compounds (51, 52) is comparable

A series of β-carbolinederivatives was synthesized by the Pictet-Spengler reaction with or without the combretastatin skeleton. The structures of these derivatives were elucidated by spectroscopic techniques. All synthesized compounds were evaluated for their anti-inflammatory activity in human neutrophils. Among them, two compounds, NTU-228 and HK-72, showed significant inhibitory effects on N-formyl-Met-Leu-Phe
