[The involvement of actin cytoskeleton in glutoxim and molixan effect on intracellular Ca(2+)-concentration in macrophages].

Glutoxim and molixan belong to new generation of disulfide-containing drugs with immunomodulatory, hepatoprotective and hemopoetic effect on cells. Using Fura-2AM microfluorimetry, two structurally distinct actin filament disrupters, latrunculin B and cytochalasin D, and calyculin A, which causes actin filaments condensation under plasmalemma, we have shown the involvement of actin cytoskeleton in the intracellular Ca(2+)-concentration increase induced by glutoxim or molixan in rat peritoneal macrophages. Morphological data obtained with the use of rhodamine-phalloidine have demonstrated that glutoxim and molixan cause the actin cytoskeleton reorganization in rat peritoneal macrophages.
