代谢

在使用立体特异性标记的前体进行的工作中，已经显示L-苯丙氨酸是细胞松弛素D的主要前体，D-和L-对映体通过苯丙酮酸快速达到平衡，这解释了两种对映体同样有效的被包含。

IN...WORK USING STEREOSPECIFICALLY LABELLED PRECURSORS, L-PHENYLALANINE WAS SHOWN TO BE THE PRIMARY PRECURSOR OF CYTOCHALASIN D, & THE RAPID EQUILIBRIUM OF D- & L-ISOMERS THROUGH PHENYLPYRUVIC ACID WAS SHOWN TO ACCOUNT FOR THE EQUALLY EFFICIENT INCORPORATION OF BOTH ENANTIOMERS.

代谢

在伞藻素D的生物合成中，将[1,2-(13)C]-醋酸盐喂食给生长的伞藻素培养物。完整醋酸单元的排列已经确定...伞藻素D起源于苯丙氨酸、蛋氨酸和9个完整的醋酸单元。八个醋酸单元以头尾相连的方式结合形成C16-多酮部分。喂食更高偶数饱和脂肪酸，如C1标记的丁酸盐、肉豆蔻酸盐和棕榈酸盐，并未显示出直接掺入。然而，它们确实经过β-氧化产生C1标记的醋酸盐，后者被掺入伞藻素D中。

IN...THE BIOSYNTHESIS OF CYTOCHALASIN D BY ZYGOSPORIUM MASONII, [1,2-(13)C]-ACETATE WAS FED TO A GROWING CULTURE OF THIS FUNGUS. THE ARRANGEMENT OF INTACT ACETATE UNITS WAS ESTABLISHED... CYTOCHALASIN D ORIGINATED FROM PHENYLALANINE, METHIONINE & 9 INTACT ACETATE UNITS. EIGHT OF THE ACETATE UNITS COUPLE IN A HEAD-TO-TAIL FASHION TO FORM THE C16-POLYKETIDE MOIETY. THE FEEDING OF HIGHER EVEN-NUMBERED SATURATED ACIDS SUCH AS C1-LABELLED BUTYRATE, MYRISTATE & PALMITATE SHOWED NO DIRECT INCORPORATION. THEY DO, HOWEVER, UNDERGO BETA-OXIDATION TO YIELD C1-LABELLED ACETATE WHICH IS INCORPORATED INTO CYTOCHALASIN D.

细胞毒素Cytochalasin D对Hela细胞的影响：样品在DMSO中溶解，浓度为10毫克/毫升，并在培养基中稀释。载玻片上的细胞进行了为期3天的处理。通过观察染色的载玻片，估计细胞毒素的程度，范围从'0'（细胞损伤很小）到'4'（完全细胞溶解）。'2'表示大约50%的生长抑制剂量。记录了与相应细胞毒性评级的具体剂量：32微克/毫升= 3.5评级；10微克/毫升= 3评级；3.2微克/毫升= 3评级；1.0微克/毫升= 2.5评级；0.32微克/毫升= 1评级。/来自表格/

CYTOTOXICITY OF CYTOCHALASIN D ON HELA CELLS: SAMPLES WERE DISSOLVED IN DMSO AT 10 MG/ML & DILUTED IN THE MEDIUM. CELLS ON COVER-GLASSES WERE TREATED FOR 3-DAYS. DEGREE OF CYTOTOXICITY WAS ESTIMATED ON A SCALE RANGING '0' (LITTLE CELLULAR DAMAGE) THROUGH '4' (COMPLETE CYTOLYSIS) IN OBSERVING THE STAINED COVER-GLASSES. '2' DENOTES APPROXIMATE 50% GROWTH-INHIBITORY DOSE. SPECIFIC DOSAGE WITH RESPECTIVE CYTOTOXICITY RATING WAS NOTED: 32 UG/ML= 3.5 RATING; 10 UG/ML= 3 RATING; 3.2 UG/ML= 3 RATING; 1.0 UG/ML= 2.5 RATING; 0.32 UG/ML= 1 RATING. /FROM TABLE/

制备方法与用途

生物活性

Cytochalasin D（Zygosporin A；NSC 209835）是一种有效且细胞渗透性的肌动蛋白聚合抑制剂，由真菌产生。它通过与G-actin结合，抑制了G-actin–cofilin的相互作用，并且还能抑制cofilin与F-actin的结合，从而减缓活细胞中肌动蛋白聚合和解聚的速率。Cytochalasin D 可以减少外泌体的释放，进而降低肿瘤环境中survivin的含量。此外，Cytochalasin D 诱导YAP磷酸化，阻止其核易位而保留在胞质中。

靶点

• G-actin
