澳洲代写：COX抑制剂
市面上最常用的COX抑制剂有布洛芬、吡罗昔康和甲灭酸等(Yaksh et al.， 2001)。COX抑制剂的第2类具有明显的低亲和力，是一种快速作用的药物。COX-1和COX-2药物的时间依赖性、高亲和力、缓慢可逆结合也遵循这一规律。COX抑制剂的第3类包括快速可逆结合，随后是COX-1和COX-2的共价修饰(FitzGerald和Patrono, 2001)。阿司匹林是COX抑制剂3类中最常见的例子。这些COX抑制剂被发现有很多用途(Hawkey, 1999)。它已被发现在治疗脊椎炎、关节炎、骨质疏松症、急性疼痛和月经痉挛等方面很有用。这些药物有能力处理一些潜在的健康状况(Hawkey, and Langman, 2003)。NSAID药物具有COX抑制剂的功能。COX抑制剂的一些功能对机体也有不良反应。已经发现COX抑制剂影响人体前列腺素胃壁衬里(Rao, and Knaus, 2008)。这会导致身体溃疡和消化性溃疡。当联合使用COX抑制剂时，会对机体产生有害影响。它甚至会导致身体的死亡问题(Munir, Enany, Zhang, 2007)。市场上最受欢迎的COX抑制剂药物之一是布洛芬。
有许多丙酸衍生物的作用原理与上述的布洛芬相同，但作用机理差别不大，它们在接下来的(Evans 2001)中进行了详细的探讨。
NSAID通常被发现阻碍花生四烯酮的生物合成途径。这导致抗炎和解热活动(弗里尔等，1993)。
澳洲代写：COX抑制剂
Most commonly developed commercially available COX inhibitors are ibuprofen, piroxicam and mefenamic acid to name a few (Yaksh et al., 2001). Category 2 of the COX inhibitors function as rapid action drugs with significantly lower-affinity, it has been found that they are reversibly binding. Time-dependent, higher-affinity, slowly reversible binding of COX-1 and COX-2 drugs follows it. Category 3 of the COX inhibitors encompasses rapid reversible binding this is subsequently followed by covalent modification of COX-1 and COX-2 of the drug (FitzGerald, and Patrono,, 2001). Aspirin is the most common example of the category 3 of the COX inhibitors. These COX inhibitors are found to have a number of purposes (Hawkey, 1999). It has been found to be useful in treatment of spondylitis, arthritis, osteoporosis, acute pain, and menstrual cramps to name a few. These drugs have the ability to deal with a number of potential health conditions (Hawkey, and Langman, 2003). NSAID drugs function as COX inhibitor drugs. Some of the functions of the COX inhibitor drugs also have adverse reactions to the body. It has been found that the COX inhibitors affect the prostaglandin stomach wall lining of the body (Rao, and Knaus, 2008). This causes the body to develop ulceration and peptic ulcers. When combinations of COX inhibitors are taken there are adverse detrimental effects to the body. It can even cause mortality issues to the body (Munir, Enany, Zhang, 2007). One of the most popular kinds of COX inhibitor drug that is found in the market is the Ibuprofen.
There are many kinds of propionic acid derivatives that function with the same principle of ibuprofen described above with small difference in the mechanism of action they are probed in detail in the following (Evans 2001).
NSAID in general are found to impede the arachidonic biosynthesis pathway. This causes anti-inflammatory and anti pyretic activities (Freer et al, 1993).
