测定Ki和k2值对COX-2的时间依赖性抑制作用[1]
纯化的COX-2 (2.3 μg)与抑制剂在180 μl的反应缓冲液中预孵育0-15 min,然后用花生四烯酸和TMPD的混合物开始反应。用上述分光光度法测定环加氧酶活性。在没有抑制剂预孵育的情况下进行的实验中,将含有酶的测定混合物加入抑制剂和花生四烯酸/TMPD乙醇溶液中引发反应。通过使用Sigmaplot软件将数据拟合到形式为y=a + b.exp(-kobst)的一阶方程中,计算出每种抑制剂浓度下随时间变化的活性损失的速率常数(kobs)。根据Rome and Lands(1975)开发的模型分析了绵羊COX-1的时间依赖性抑制。在该模型(方案1)中,酶和抑制剂的初始可逆结合(以解离常数Ki为特征)之后是一级失活过程(以一级速率常数k2为特征)。该过程的逆转速率(k-2)可以忽略不计。 抑制剂结合的化学计量学测定[1] 等分纯化的COX-2 (0.25 mg ml-1,亚基浓度为3.4 μm)在不同浓度的抑制剂(0-8 μm)存在的缓冲液(100 mm Tris-HCl, pH 8.0, 5 mm EDTA, 1 mm苯酚)中孵育15或30分钟。然后去除等分(20 μl),通过吸氧测定剩余的环加氧酶活性,如上所述。酶的浓度由酸水解后的氨基酸浓度决定(Percival et al., 1994)。 花生四烯酸对COX-2抑制的时间依赖性竞争[1] 将纯化的COX-2 (3.6 μg)稀释到含有60 mm二乙基二硫代氨基甲酸的预孵化液(0.03 ml, 100 mm Tris-HCl, pH 8.0, 5 mm EDTA, 2 mm苯酚)中,以防止底物氧化(Lands et al., 1974)和10 μm抑制剂,或10 μm抑制剂加5 μm花生四烯酸,或10 μm抑制剂加30 μm花生四烯酸。预孵育0-4分钟后,在30°C条件下用耗氧量测定总酶的酶活性,如上所述。 |

Effects During Pregnancy and Lactation
◉ Overview of Drug Use During Lactation Since indomethacin is present in low levels in breast milk and can be given directly to infants, it is generally safe for breastfeeding women. However, for breastfeeding women, especially newborns or premature infants, other medications with more information available for use during lactation may be more suitable. ◉ Effects on Breastfed Infants In one case report, a breastfeeding mother took indomethacin daily from day four to day six postpartum, increasing the dose to 200 mg (3 mg/kg). On the day indomethacin was discontinued, the infant experienced generalized tonic-clonic seizures, which recurred the following day. No metabolic abnormalities were found to explain these seizures, and indomethacin levels in the mother or infant were not measured. This case was initially considered to suggest that indomethacin may cause seizures; however, subsequent research and the established therapeutic use of indomethacin in newborns make such a causal relationship seem unlikely. In one study, seven women breastfed their newborns while taking indomethacin. No adverse reactions were observed in any of the infants. ◉ Effects on lactation and breast milk As of the revision date, no relevant published information was found. |

| 其他信息 |
Indomethacin sodium is the sodium salt of indomethacin, a methylated indole derivative with anti-inflammatory, analgesic, antipyretic, and uterine contraction-inhibiting effects. Indomethacin is a non-selective, reversible competitive inhibitor of cyclooxygenases 1 and 2, thereby blocking the conversion of arachidonic acid to prostaglandin precursors. Therefore, prostaglandin synthesis is reduced, and prostaglandin-mediated activities (including pain, inflammation, fever, and uterine contractions) are inhibited. Indomethacin sodium is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase, which is essential for the formation of prostaglandins and other endogenous active substances. It also inhibits the motility of polymorphonuclear leukocytes. See also: Indomethacin (with active fraction).
