Ordering Information

Biological Activity

ML188 is a selective, non-covalent inhibitor of SARS-CoV 3CLpro. By specifically targeting the viral main protease 3CLpro, ML188 inhibits the proteolytic cleavage of overlapping replicase polyproteins into functional non-structural proteins. This block in polyprotein maturation impairs assembly of the viral replication-transcription complex, ultimately suppressing coronavirus replication and downstream viral propagation, thereby demonstrating broad cellular antiviral activity.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
