pitstop 2

Pitstop2 is an amphipathic protein-bound inhibitor of the clathrin terminal domain (IC50=12 μM) with selectivity. Pitstop2 severely interferes with receptor-mediated endocytosis, HIV entry and synaptic vesicle cycling. Pitstop2 has antitumor activity.

Pitstop 2d is a Clathrin inhibitor with an IC50 of less than 2 μM. It binds to the Clathrin N-terminal β-propeller domain, thereby inhibiting Clathrin's function and dynamics and blocking the entry of VSV. Pitstop 2d specifically inhibits clathrin-mediated endocytosis (Endocytosis) and does not interfere with non-clathrin-dependent endocytic processes.

Pitstop 2c is a Clathrin inhibitor with an IC50 of less than 2 μM. It binds to the Clathrin N-terminal β-propeller domain, impairing Clathrin's function and dynamics, and blocking the entry of vesicular stomatitis virus (VSV). Pitstop 2c inhibits clathrin-mediated endocytosis (Endocytosis) but does not inhibit non-clathrin-dependent endocytosis.

Clathrin-IN-1 is a inhibitor of clathrin, and inhibits clathrin-mediated endocytosis (CME) by associating with the terminal domain of clathrin. It has the potential for anti-cancer research.

Pitnot-2 is an inert analogue of the clathrin inhibitor Pitstop 2, commonly employed as a negative control in experimental studies.
