RTIL 13 is a highly effective inhibitor of dynamin GTPase, exhibiting an IC50 value of 2.3 μM for dynamin I GTPase. Furthermore, it selectively interacts with the pleckstrin homology lipid binding domain. This compound effectively suppresses both receptor-mediated and synaptic vesicle endocytosis, demonstrating IC50 values of 9.3 μM and 7.1 μM, respectively.
Biotin-TAT (47-57) is a biotin-tagged transactivator of transcription, commonly employed as a protein transduction domain (PTD) in various primary cells. Its transduction capacity is contingent on ATP and temperature, suggesting the participation of endocytosis.
Dios-Arg is a steroid-based cationic lipid that contains a diosgenin skeleton coupled to an L-arginine head group. It forms a complex with plasmid DNA and decreases plasmid DNA migration in an agarose-gel retardant assay at charge ratio greater than or equal to 4. Dios-Arg facilitates transfection of plasmid DNA into H1299 and HeLa cells in the presence and absence of fetal bovine serum, an effect that is reversed by the lipid raft-mediated endocytosis inhibitor methyl-β-cyclodextrin and the caveolae-mediated endocytosis inhibitor genistein . It has been used, coupled to 1,2-dioleoyl-sn-glycero-3-PE , to bind siRNA and plasmid DNA to form cationic lipid nanoparticles for intracellular transport. Dios-Arg is cytotoxic to H1299 and HeLa cells (IC50s = 83.5 and 74.1 μg/ml, respectively).
