代谢

肝脏的，最可能是通过肝微粒体酶。在其体液中，其主要代谢物为5-羟基丹特罗林和丹特罗林的乙酰氨基代谢物。另一种结构未知的代谢物似乎与后者有关。丹曲林也可能经历水解和随后的氧化，形成硝基苯基呋喃酸。

Hepatic, most likely by hepatic microsomal enzymes. Its major metabolites in body fluids are 5-hydroxydantrolene and an acetylamino metabolite of dantrolene. Another metabolite with an unknown structure appears related to the latter. Dantrium may also undergo hydrolysis and subsequent oxidation forming nitrophenylfuroic acid.

代谢

丹曲林通过肝脏混合功能氧化酶系统代谢成5-羟基丹曲林，它与葡萄糖醛酸或硫酸结合。它还通过硝基还原酶代谢成氨曲林，后者抑制肝脏混合功能氧化酶系统。氨曲林的乙酰化作用阻断了其抑制效果。硝基还原酶途径中的中间体形成葡萄糖苷酸和巯基尿酸结合物。巯基尿酸结合反应是丹曲林电负性代谢物的一种解毒机制。

DANTROLENE IS METABOLIZED BY THE HEPATIC MIXED FUNCTION OXIDASE SYSTEM TO 5-HYDROXYDANTROLENE WHICH IS CONJUGATED WITH GLUCURONIC ACID OR WITH SULFATE. IT IS ALSO METABOLIZED BY NITROREDUCTASE TO AMINODANTROLENE WHICH INHIBITS THE HEPATIC MIXED FUNCTION OXIDASE SYSTEM. ACETYLATION OF AMINODANTROLENE BLOCKS THE INHIBITORY EFFECTS. INTERMEDIATES IN THE NITROREDUCTASE PATHWAY FORM GLUCURONIDE & MERCAPTURIC ACID CONJUGATES. THE MERCAPTURIC ACID CONJUGATION REACTION IS A DETOXIFICATION MECHANISM FOR AN ELECTROPHILIC METABOLITE OF DANTROLENE.

毒理性

• 肝毒性

轻度的、无症状的血清转氨酶升高在使用丹曲林治疗期间相对不常见（1%），但临床上估计每千人治疗者中会有1到2人发生肝损伤（0.1%到0.2%）。肝损伤可能是严重的；有急性肝衰竭甚至死亡的病例报道（案例1）。临床明显肝损伤的潜伏期从一周到几个月不等，但通常在开始治疗的前6个月内（案例2）。更严重的病例通常突然发作，伴有黄疸、恶心和疲劳，并且病情迅速进展。过敏表现如发热、皮疹和嗜酸性粒细胞增多是罕见的，自身免疫特征也很少见。酶升高的模式主要是肝细胞型。肝脏组织学显示急性肝炎样的图像。通常在1到3个月内完全恢复。女性、老年患者和服用较高剂量的患者似乎更容易发生丹曲林肝毒性。

Mild, asymptomatic serum aminotransferase elevations during dantrolene therapy are relatively uncommon (1%), but clinically over liver injury is estimated to occur in 1 to 2 per thousand treated persons (0.1% to 0.2%). The liver injury can be severe; cases of acute liver failure and even death have been described (Case 1). The latency to onset of clinically apparent liver injury ranges from one week to several months, but is usually within the first 6 months of starting therapy (Case 2). More serious cases are associated with a sudden onset with jaundice, nausea and fatigue, and rapid progression. Allergic manifestations such as fever, rash and eosinophilia are rare, as are autoimmune features. The pattern of enzyme elevations is predominantly hepatocellular. Liver histology demonstrates an acute-hepatitis like picture. Recovery is usually complete within 1 to 3 months. Women, the elderly, and patients taking higher doses appear to be more susceptible to developing dantrolene hepatotoxicity.

  Dantrolene analogues revisited: general synthesis and specific functions capable of discriminating two kinds of Ca2+ release from sarcoplasmic reticulum of mouse skeletal muscle

  摘要：

  The general synthesis of dantrolene analogues with various substituents on its phenyl ring has been developed via palladium-catalyzed cross-coupling reactions, the Stille or Suzuki reaction, as the key step. The effects of synthesized analogues have been evaluated by two kinds of Ca2+ release modes from sarcoplasmic reticulum (SR) of mouse skeletal muscle fibers based on: (1) the measurement of twitch contraction caused by the physiological Ca2+ release (PCR) of intact skeletal muscle and (2) the rate of Ca2+-induced Ca2+ release (CICR) in saponin-treated skinned muscle fibers. Although dantrolene, a lead compound, inhibits both twitch contraction and CICR, some structurally modified analogues exhibit one or the other of these effects. The methoxy congener, GIF-0185, potently inhibits the twitch contraction without affecting the CICR, while GIF-0166 and GIF-0248, the ortho-nitro regioisomer and ortho, ortho-dinitro substituted analogues, respectively, doubly potentiate the CICR exclusively.
