Shepherdine, a harmala-type indole and tetrahydro-β-carboline alkaloid, is an antioxidant. Shepherdine scavenges free radicals via single electron transfer from its indole ring, forming an indolyl cation or neutral radical, and may convert to aromatic β-carbolines during this process. Shepherdine can be used for research on antioxidant activity [1].
In Vitro, Shepherdine (Compound 1) acts as a potent ABTS•+ radical scavenger in a cell-free assay[1].
