生物活性

Pitstop 2 is a clathrin inhibitor which inhibits clathrin-mediated endocytosis (CME) by associating with the terminal domain of clathrin. Pitstop 2 has the potential for anti-cancer research[1][2].

体外研究
(In Vitro)

Pitstop 2 (20-40 μM; 30 min) inhibits the endocytosis of transferrin in J774A.1 macrophages and does not compromise cell viability[1].
Pitstop 2 (20-40 μM; 30 min) does not affect the internalization of cholera toxin B in J774A.1 macrophages[1].
Pitstop 2 (0.001-100 μM; 6 h) inhibits the mitotic spindle and impairs mitotic progression in HeLa cells[2].
Pitstop 2 (1-30 μM; 24 h) induces apoptosis and inhibits cell growth in dividing cancer cells[2].
Pitstop 2 (1-30 μM; 48 h) does not affect the growth and viability of non-tumourigenic NIH3T3 fibroblasts[2].

上海金畔生物科技有限公司 has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[2]

Cell Line: HeLa cells
Concentration: 1, 3, 10, 30 μM
Incubation Time: 24 hours
Result: Reduced the total number of viable HeLa cells markedly in a dose-dependent manner.
