依托泊苷 (英語:Etoposide,又名鬼臼乙叉苷VP-16,商品名EposinEtopophosVepesid)是一种广泛应用的拓扑异构酶抑制剂化疗药物。它是鬼臼毒素(一种大量存在于鬼臼,尤其是盾叶鬼臼中的物质)的人工合成衍生物

历史

鬼臼作为中药使用具有上千年的历史,早在东汉时期《神农本草经》就已有记载。然而,由于毒性剧烈(《神农本草经》中被列为“下品”),一直以来它的应用受到了限制。[1]在1950年,科学家开始合成一系列的鬼臼毒素衍生物,并发现其中一种名为4'-去甲氧基表鬼臼毒素苯亚甲基糖苷(DEPBG)的物质最为有效(相对于毒性来说)。随后他们又研制出了两种有着更强抗癌活性的DEPBG衍生物,分别是在1966年被合成依托泊苷和1967年被合成的替尼泊苷。依托泊苷在在1983年由美国FDA批准上市。[2]

作用机理

Etoposide forms a ternary complex with DNA and the topoisomerase II enzyme (which aids in DNA unwinding), prevents re-ligation of the DNA strands, and by doing so causes DNA strands to break. Cancer cells rely on this enzyme more than healthy cells, since they divide more rapidly. Therefore, this causes errors in DNA synthesis and promotes apoptosis of the cancer cell.[2][3]

用途

依托泊苷被用来治疗多种癌症,包括肺癌睾丸癌卡波济氏肉瘤尤文氏肉瘤淋巴瘤多形性成胶质细胞瘤和急性非淋巴细胞白血病等。它常与其他化疗药物组合用于联合化疗,如与博来霉素泼尼松组成的BEP联合疗法(用于睾丸癌的一线治疗)。它还被用于骨髓移植干细胞移植的预处理。[2]

给药途径

It is given intravenously or orally in capsule form. If the drug is given by IV, it must be done slowly over a 30- to 60-minute period because it can lower blood pressure as it is being administered. Blood pressure is checked often during infusing, with the speed of administration adjusted accordingly.

In general, patients are advised to call their doctor in case of fever, symptoms of infection, or painful injection sites, as these may progress severely without adequate medical attention.[4]

Patients are advised to drink large amounts of fluids after treatment to prevent damage to the bladder and kidneys, typically 1.5 to 3.5 liters of water on the day of treatment and for several days after.

除此之外,与华法令合用会增强后者的抗凝血作用,可能引起出血[4]
