A potent, selective inhibitor of clathrin-independent endocytosis with IC50 of 18 uM (inhibition of clathrin TD-amphiphysin B/C complex formation).

A small molecule inhibitor of clathrin terminal domain and inhibits clathrin-mediated endocytosis.

Endosidin 9 (ES9) is a novel mitochondrial uncoupler, and a potent inhibitor of clathrin-mediated endocytosis (CME) in different systems, strongly reduces FM4-64 uptake in Arabidopsis root cells with IC50 of 5 uM.Endosidin 9 (ES9) inhibits CME dynamics and organelle movement in the cytoplasm.Endosidin9 (ES9) inhibits clathrin-mediated endocytosis largely through cytoplasmic acidification.

Wbox2 is a membrane-permeant peptide that potently inhibits clathrin-mediated endocytosis (CME, IC50=3 uM), binds to SNX9 and AP2 and perturbs clathrin interactions with AP2 and SNX9.Wbox2 has no effect on cell viability at ≤30 uM and exhibited an IC50 for cytotoxicity (>40 uM) that is 10-fold higher than that needed to inhibit CME.Wbox2 interferes with AP2–clathrin interactions and alters CCP dynamics, binds to both AP2 and SNX9 with binding affinities of 4.0 and 26.2 uM.
