Oxygen 70-76 ETS transcription factor ERG Homo sapiens 11-15 30282042-8 2018 Compared to their parent compounds, only an oxygen atom was introduced in the nitrogen oxidative isoforms to compensate for the N+ - charge, suggesting that the protonated nitrogen is the key group for strychnine and brucine binding to hERG channel. Oxygen 44-50 ETS transcription factor ERG Homo sapiens 236-240 30282042-12 2018 This study suggests that introduction of an oxygen to compensate for the N+ - charge could be a useful strategy for reducing hERG potency and increasing the safety margin of alkaloid-type compounds in drug development.
