细胞松弛素J用于肌动蛋白聚合研究。细胞松弛素是有效的霉菌毒素，其结合到肌动蛋白丝的带刺的末端，从而抑制了亚基的缔合和解离。用作细胞学研究的工具。这些真菌毒素的化学结构与其特征相关，该化学结构的特征是高度取代的氢化异吲哚环，该环与大环稠合。细胞松弛素J是细胞松弛素H的脱乙酰基类似物，尽管具有较低的效力，抗菌，抗真菌，杀线虫和抗肿瘤活性，但它们具有相似的活性。 Cytochalasin J is used in actin polymerization studies. Cytochalasins are potent mycotoxins which bind to the barbed end of actin filaments resulting in inhibition of both the association and dissociation of subunits. Used as a tool for cytological research. These fungal toxins are related by their chemical structure characterized by a highly substituted hydrogenated isoindole ring to which is fused a macrocyclic ring. Cytochalasin J is the deacetyl analogue of cytochalasin H and exhibits similar, though less potent, antibacterial, antifungal, nematocidal and antitumor activities. Application： Cytochalasin J is a cell-permeable fungal toxin used in actin polymerization studies and cytological research
