Its antiproliferative (EC50 ~ 0.4 µM) and cytotoxic (EC50 ~ 12 µM) effects on glioma and neuroblastoma cell lines indicate it is also a σ1 antagonist. PB28 also inhibited cell growth in MCF7 breast cancer lines, and was strongly synergistic with doxorubicin. PB28 potently inhibited Kv2.1 channels in a σ-independent manner. Recently, PB28 showed potent (IC50 = 280 nM; 20-fold more than hydroxychloroquine) anti-SARS-CoV2 activity, without cardiac side effects.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 18px\"\u003e\u003cstrong\u003e\u003cu\u003eApplication Procedures\u003c\/u\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eFirst dissolved in DMSO (up to 25 mg\/ml) or in Water (up to 5 mg\/ml), then diluted to aqueous buffer.
