PB28 is a very potent high affinity (Ki = 5.3 nM1, 0.34 nM2) sigma 2 agonist. Selective for sigma 2 over sigma1 (approx 30-40x).1,2 PB28 inhibited cell growth in MCF7 and MCF7 ADR breast cancer cells and displayed strong synergism with doxorubicin.3 PB28 potently inhibited Kv2.1 currents in a sigma-independent manner.4 PB28 was recently found to have potent (IC50 = 280 nM) anti-SARS-CoV2 activity.5
