In Vitro At concentrations of 0.5-2.0 mM, Bunaftide causes contraction and rounding of the cells with loss of microvilli-like processes. Aggregates of dense, partly granular, partly fibrillar material form in the cytoplasm and the rough endoplasmic reticulum became vesiculated. Bundles of actin filaments are disrupted, forming rings, coils, and granules. 0.4 mM Bunaftide increases and 0.8-1.0 mM markedly decreases the percentage of mitotic cells, without accumulation of cells in any particular stage of mitosis. The drug may arrest the cell cycle at some point before mitosis; it may have a critical concentration above which the arrest becomes permanent[1]. Bunaftide at 1, 5 and 10 mg/L produces a concentration-dependent depression of the maximum rate of rise of the action potential in guinea pig papillary muscle preparations without affecting the resting membrane potential and the action potential amplitude. The action potential duration (APD50, APD90) is significantly prolonged by the treatment with 1 and 5 mg/L Bunaftide, while it is not changed by the treatment with 10 mg/L[2].
Cell Assay Human embryonic fibroblasts and HeLa cells are seeded into 35-mm plastic Petri dishes at a density of 1x105 cells/cm2. Bunaftide is used in final concentrations of 0.1-2.0 mM. The cells are exposed to the drug for periods ranging from 15 min to 24 h. To allow the cells to recover, the Bunaftide medium is removed and the cultures are left in standard medium for 4-24 h[1].
