Merbromin
Merbromin is a mixed inhibitor of the 3-chymotrypsin-like protease (3CLpro) of SARS-CoV-2, with an IC50 of 2.7 μM. Merbromin effectively inhibits the replication of the Zika virus (ZIKV) and shows anti-ZIKV activity by inhibiting ZIKVpro. Merbromin can also be used as a topical disinfectant for cuts and scrapes, and it serves as a biological dye.

3CLpro 2.7 μM (IC50) |
Merbromin (0-10 μM) affects both the KM and Kcat of 3CLpro, where the KM value increases from 9.02 μM to 14.28 μM, and the Kcat value decreases from 1.45 min to 0.63 min[1].
Merbromin with the KD for 3CLpro is 0.23 μM[1].
