Ordering Information

Biological Activity

ZCL278 is a selective small-molecule inhibitor of Cdc42 GTPase (Kd 11.4 μM). By directly binding to Cdc42, ZCL278 disrupts its interaction with downstream effectors and suppresses Cdc42-dependent signaling pathways involved in actin cytoskeletal dynamics. This inhibition blocks filopodia formation and reduces cell migration and invasion in cancer cells without causing significant cytotoxicity.

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).
