- HCV hepatitis C
- influenza including canine flu
- viral gastroenteritis caused by rotavirus or norovirus.
- Nitrozolidine can also fight infections caused by bacteria such as Clostridium difficile (CD), Mycobacterium tuberculosis (including drug-resistant tuberculosis) and Helicobacter pylori, and also has a good inhibition of bacterial biofilm formation. effect.
- Nitrozolidine is a prodrug that is rapidly hydrolyzed into its active metabolite Tizoxanide (TIZ) in vivo.
- TIZ active metabolite Tizoxanide
- Pharmacokinetic studies in humans have shown that nitazoxanide can be absorbed from the gastrointestinal tract after oral administration, about one-third of the oral dose is excreted from the urine, and two-thirds of the oral dose is excreted from the feces.
- nitazoxanide is rapidly metabolized by plasma esterase (half-life at 37 ° C for about 6 minutes), hydrolytically deacetylated to become its active metabolite tazoxanide, thus in plasma, urine, bile No detectable in the stool Special existence.
- Tizoxanide can continue to be glucuronylated in vivo to glucuronidized tizoxanide without pharmaceutically active activity.
- Tizoxanide is present in plasma, urine, bile, and feces, and Tizoxanide Glcuronide is also present in plasma, urine, and bile.
- Nitrozolidine has good biological properties such as diverse biological activities and good safety, but there are also some obvious deficiencies.
- the inadequacies mainly exist in the following two aspects.
- Nitrozolidine has a problem of low bioavailability, short half-life, and low blood concentration. Examination of the pharmacokinetics laboratory of the Institute of Pharmacology and Toxicology of the Academy of Military Medical Sciences found that the absolute bioavailability of the oral nitazoxide suspension in rats was only 7.2%. According to the literature, oral administration of nitazoxanide in healthy adults, after a single dose of 500mg, the peak time of the active metabolite tizoxanide is 3-4h, and the AUC value is about 3.9-11.3 g*h/mL. The peak concentration C max is 1.9 g/mL (value range 1.1-2.5) and the half-life is very short, only 1.03 to 1.6 hours.
- the activity is relatively low.
- the minimum inhibitory concentration MIC of nitazoxan to Mycobacterium tuberculosis is 12 to 28 g/mL (median 16 g/mL); nitazoxanide and thiazole
- the minimum inhibitory concentration (MICs) of 103 strains of Helicobacter pylori was between 0.25 and 8 g/mL, and the 50%3 ⁇ 4 low inhibitory concentration (MICso) was g/mL, 90% minimum inhibitory concentration (MIC 90 ).
- nitazoxanide has a low bioavailability, a short half-life, and a low blood drug concentration.
- nitazoxanide When nitazoxanide is used to treat parasitic infections such as intestinal protozoa and helminths, it does not require nitazoxanide to enter the bloodstream. Therefore, nitazoxanide has poor oral absorption, low bioavailability, and blood concentration. Low sexual susceptibility does not affect the efficacy of parasitic infections such as protozoa and helminths.
- nitazoxanide is used in the treatment of drug-resistant Mycobacterium tuberculosis, Helicobacter pylori or methicillin-resistant Staphylococcus aureus, or in the treatment of viral infections such as influenza and rotavirus, the blood concentration should be high. At or near its 90% minimum inhibitory concentration (MIC 90 ) or 90% inhibitory virus concentration (EC 90 ). At this time, the oral absorption of nitazoxanide is poor, the bioavailability is not high, and the shortcomings of low blood concentration are inevitable, which directly affects the efficacy. Play.
- MIC 90 90% minimum inhibitory concentration
- EC 90 90% inhibitory virus concentration
- nitazoxanide drugs are to be treated with drug-resistant Mycobacterium tuberculosis, Helicobacter pylori or methicillin-resistant Staphylococcus aureus, or for the treatment of viral infections such as influenza and rotavirus, It is necessary to increase the bioavailability of tizoxide, increase the blood concentration, and prolong the half-life to adapt to the therapeutic effects in antibacterial and antiviral aspects.

本发明提供一类式I所示的替唑尼特氨基甲酸酯类化合物及其可药用的盐或水合物或溶剂化物,以及该类化合物在药学中的应用。
Description
替唑尼特氨基甲酸酯及其在药学中的应用 技术领域
本发明涉及替唑尼特氨基羧酸酯类化合物,特别是涉及一类替唑尼 特氨基甲酸酯类化合物及其可药用的盐或水合物或溶剂化物,以及该类 化合物在药学中的应用。 背景技术
硝唑尼特 (Mtazoxanide , NTZ)是由 Romark实验室开发的一种 噻唑苯甲酰胺类化合物, 有多样性的生物学活性。 其化学名为" 2-乙酰 氧基 -N-(5-硝基 -2-噻唑)苯甲酰胺", 化学式为 C 12H9N305S, 熔点为 202 °C , 是一种淡黄色粉末, 不溶于水, 微溶于乙醇, 能溶于四氢呋喃、 二甲基亚砜(DMSO )和 N,N—二甲基甲酰胺 ( DMF)等有机溶剂。
研究表明硝唑尼特其在人体可以有效对抗多种原虫、 蠕虫类寄生 虫, 具体包括: 肠兰伯式鞭毛虫、 阿米巴虫、 隐孢子虫、 环孢子虫、 毛 滴虫、 肠脑炎微孢子虫、 贝氏等孢子球虫、 人芽囊原虫、 结肠小袋虫、 人体蛔虫、 毕氏肠微孢子虫、 绦虫(包括牛肉绦虫、 短膜壳绦虫) 、 微 小膜壳绦虫、 贾第虫、 利什曼原虫、 肝片吸虫等。硝唑尼特对乙型肝炎 ( HBV ) 、 丙型肝炎(HCV ) 、 流感 (包括犬流感) 、 以及轮状病毒 或诺若病毒引起的病毒性肠胃炎等病毒感染性疾病有很好的治疗效果。 硝唑尼特还可以对抗难辨梭状芽胞杆菌 ( Clostridium difficile , CD ) 、 结核杆菌(包括耐药结核菌)和幽门螺旋杆菌等细菌引起的感染, 对细 菌生物膜的形成也有艮好的抑制作用。
硝唑尼特是一种前药,给药后在体内很快水解为其活性代谢产物替 唑尼特(Tizoxanide , TIZ) 。 对人体进行药物代谢动力学研究显示, 经口服给药后硝唑尼特可以从胃肠道吸收, 大约 1/3的口服剂量从尿液 排泄, 2/3的口服剂量从粪便中排泄。 在血液中, 硝唑尼特快速地被血 浆酯酶代谢 (在 37°C下半衰期约 6分钟), 水解脱去乙酰基成为其活性 代谢产物替唑尼特, 因而在血浆、尿液、 胆汁和粪便中检测不到硝峻尼
特的存在。替唑尼特在体内可继续被葡萄糖醛酸化为没有药物活性的葡 萄糖醛酸化替唑尼特。 替唑尼特存在于血浆、 尿液、 胆汁和粪便中, 葡 萄糖醛酸化替唑尼特 ( Tizoxanide Glcuronide )也存在于血浆、 尿液和 胆汁中。
硝唑尼特具有生物活性多样,安全性好等良好的药物性质,但也存 在一些明显的不足, 不足之处主要存在于以下两个方面。
( 1 )硝唑尼特存在生物利用度不高, 半衰期较短, 血药浓度较低 的问题。 军事医学科学院毒物药物研究所药代动力学研究室的检测发 现, 大鼠口服硝唑尼特混悬液的绝对生物利用度仅为 7.2%。 另据文献 报道, 健康成年人口服硝唑尼特, 单次给药 500mg后, 活性代谢产物替 唑尼特的达峰时间为 3-4h, AUC值约为 3.9-11.3 g*h/mL,峰浓度 C max 为 1.9 g/mL (数值范围 1.1-2.5), 半衰期很短, 只有为 1.03到 1.6小时。
( 2 )活性相对较低, 例如, 硝唑尼特对结核分枝杆菌的最低抑菌 浓度 MIC是 12到 28 g/mL (中位数为 16 g/mL ) ; 硝唑尼特和替唑尼特 对 103株幽门螺旋杆菌最低抑菌浓度 ( MICs )在 0.25 to 8 g/mL之间, 50%¾低抑菌浓度 ( MICso )是 g/mL, 90%最低抑菌浓度 ( MIC90 ) 是 4 g/mL; 硝唑尼特和替唑尼特在好氧或者微氧条件下, 对表皮葡萄 球菌或其它葡萄球菌(包括抗甲氧西林金黄色葡萄球菌株)的最小抑菌 浓度 ( MIC ) 为 8 ~ 16 g/mL; 硝唑尼特在 MDCK细胞中, 对 PR8流感 病毒株的 EC50 为 l g/mL,EC90 为 7 g/mL。
可以看出, 硝唑尼特存在生物利用度不高, 半衰期短, 血药浓度较 低的不足。 当硝唑尼特用于治疗肠道原虫、 蠕虫等寄生虫感染时, 不需 要硝唑尼特进入血液即可发挥作用, 因此硝唑尼特口服吸收差,生物利 用度不高,血药浓度低的性庸并不会对其治疗原虫、蠕虫等寄生虫感染 的疗效产生影响。但如果将硝唑尼特应用于耐药结核杆菌、幽门螺旋杆 菌或抗甲氧西林金黄色葡萄球菌的治疗,或抗流感、轮状病毒等病毒感 染性疾病的治疗时, 血药浓度应该高于或接近其 90%最低抑菌浓度 ( MIC90 )或 90%抑病毒浓度 ( EC90 )。 这时硝唑尼特口服吸收差, 生 物利用度不高,血药浓度低的缺点必然会体现出来, 而直接影响药效的
发挥。
因此,如果要将硝唑尼特类药物应用于耐药结核杆菌、 幽门螺旋杆 菌或抗甲氧西林金黄色葡萄球菌的治疗,或抗流感、轮状病毒等病毒感 染性疾病的治疗, 就有必要提高其以替唑尼特计的生物利用度,增加血 药浓度, 延长半衰期, 以适应在抗菌和抗病毒等方面的治疗效果。 发明内容
