Myristyl trimethyl ammonium bromide and octadecyl trimethyl ammonium bromide are surface-active small molecule dynamin inhibitors that block endocytosis mediated by dynamin I or dynamin II.

abstract：:Amphetamine congeners [e.g., 3,4-methylenedioxymetamphetamine (MDMA), or "ecstasy"] are substrates for monoamine transporters (i.e., the transporters for serotonin, norepinephrine, and dopamine); however, their in vivo-action relies on their ability to promote monoamine efflux. The mechanistic basis for this counter t...
