Securinine

Securinine (CAS No.: 5610-40-2) is a plant derived alkaloid isolated primarily from Securinega suffruticosa and is broadly classified as a neuroactive natural product used in life sciences research as a gamma aminobutyric acid type A receptor antagonist, with experimental evidence supporting modulation of inhibitory neurotransmission and downstream excitation linked to receptor blockade, ion channel mediated signaling balance, and cellular response programs relevant to neuropharmacology and mechanism based screening; within biomedical research and drug discovery workflows it is commonly applied as a pharmacological probe to investigate GABAergic pathway function, receptor pharmacology, and network level signaling effects in cell based systems and preclinical animal models, while reported activity is generally described in the nanomolar to micromolar range depending on assay format, receptor context, and readout methodology, and practical study designs typically optimize exposure conditions empirically because the concentrations or doses used in experiments typically depend on specific experimental designs and research objectives.
