| Bioactivity | Trimethyloctadecylammonium bromide is an inhibitor of dynamin, with an IC50 value of 1.9 μM for dynamin I. Trimethyloctadecylammonium bromide exhibits antibacterial activity against Staphylococcus aureus[1][2]. Related Catalog Research Areas >> Infection Signaling Pathways >> Cytoskeleton >> Dynamin Target IC50: 1.9 μM (Dynamin I)[1] In Vitro Trimethyloctadecylammonium bromide (1 μM-100 μM; 10 min) inhibits EGF-A488 endocytosis in COS-7 cells, with an IC50 value of 16 μM[1]. Trimethyloctadecylammonium bromide (30 μM; 10 min; 37 ℃) shows no effect on EGFR activation in A431 cells with insignificant EGFR autophosphorylation change[1]. Trimethyloctadecylammonium bromide (stearyl-) (1 nM-1 mM) inhibits Staphylococcus aureus with of 59.5 nM (CKD assay) and 0.33 mM (CMC assay), respectively[2].
