    • The novel positively charged pro-drugs of prostaglandins, prostacyclins and related compounds in the general formula (2) 'Structure 2' were designed and synthesized. The compounds of the general formula (2) 'Structure 2' indicated above can be prepared from protected prostaglandins, prostacyclins, and related compounds, by reaction with suitable alcohols, thiols, or amines and coupling reagents, such as N, N'-Dicyclohexylcarbodiimide, N, N'-Diisopropylcarbodiimide, O-(Benzotriazol-1-yl)-N,N,N',N'-tetramethyluronium tetrafluoroborate, O-(Benzotriazol-1-yl)-N,N,N',N'-tetramethyluronium hexafluorophosphate, Benzotriazol-1-yl-oxy-tris (dimethylamino)phosphonium hexafluorophosphate, et al. The positively charged amino groups of these pro-drugs not only largely increases the solubility of the drugs in water, but also bonds to the negative charge on the phosphate head group of membranes and pushes the pro-drug into the cytosol. The results suggest that the pro-drugs diffuse through human skin ~1000 times faster than do prostaglandins, prostacyclins, and related compounds. In plasma, more than 90% of these pro-drugs can change back to the parent drugs in a few minutes. The prodrugs can be used medicinally in treating any prostaglandins, prostacyclins, and related compounds-treatable conditions in humans or animals. The prodrugs can be administered transdermally for any kind of medical treatments and avoid most of the side effects of prostaglandins, prostacyclins, and related compounds. Controlled transdermal administration systems of the prodrug enable prostaglandins, prostacyclins, and related compounds to reach constantly optimal therapeutic blood levels to increase effectiveness and reduce the side effects of prostaglandins, prostacyclins, and related compounds. Another great benefit of transdermal administration of these pro-drugs is that administering medication, especially to children, will be much easier.
    • 设计并合成了通式(2)“结构2”中前列腺素,前列环素及相关化合物的新型带正电荷的前药。 上述通式(2)“结构2”的化合物可以由保护的前列腺素,前列环素和相关化合物通过与合适的醇,硫醇或胺的反应和偶联试剂如N,N'-二环己基碳二亚胺 ,N,N'-二异丙基碳二亚胺,O-(苯并三唑-1-基)-N,N,N',N'-四甲基脲四氟硼酸盐,O-(苯并三唑-1-基)-N,N,N',N' 四甲基脲六氟磷酸盐,苯并三唑-1-基 - 氧 - 三(二甲基氨基)鏻六氟磷酸盐等。 这些前药的带正电荷的氨基不仅大大增加了药物在水中的溶解度,而且还与磷酸盐头基上的负电荷键合,并将前药推入胞质溶胶中。 结果表明,前药通过人体皮肤分散,比前列腺素,前列环素及相关化合物快1000倍。 在血浆中,超过90%的这些前药可以在几分钟内改变为母体药物。 前药可以在医学上用于治疗人或动物中的任何前列腺素,前列环素和相关化合物 - 可治疗的病症。 前药可以通过皮肤施用于任何种类的医学治疗,并避免前列腺素,前列环素和相关化合物的大部分副作用。 前药的受控透皮给药系统使前列腺素,前列环素和相关化合物达到不断优化的治疗血液水平以增加有效性并减少前列腺素,前列环素和相关化合物的副作用。 经皮给药这些前药的另一大好处是给予药物,尤其是给儿童服用药物将容易得多。

    • The novel positively charged pro-drugs of ketoprofen and fenoprofen in the general formula(1) 'Structure 1' were designed and synthesized. The compounds of the general formula(1) 'Structure 1' indicated above can be prepared from functional derivatives of ketoprofen and fenoprofen, (for example acid halides or mixed anhydrides), by reaction with suitable alcohols, thiols, or amines. The positively charged amino groups of these pro-drugs not only largely increases the solubility of the drugs, but also bonds to the negative charge on the phosphate head group of membranes and pushes the pro-drug into the cytosol. The results suggest that the pro-drugs, diethylaminoethyl 2-(3-benzoylphenyl) propionate.AcOH and diethylaminoethyl 2-(3-phenoxyphenyl) propionate.AcOH diffuses through human skin ~125 times faster than does ketoprofen and fenoprofen. It takes 1-2 hours for ketoprofen or fenoprofen to reach the peak ketoprofen or fenoprofen plasma level when they are taken orally, but diethylaminoethyl 2-(3-benzoylphenyl) propionate.AcOH or diethylaminoethyl 2-(3-phenoxyphenyl) propionate.AcOH only took about 40 minutes to reach the ketoprofen or fenoprofen peak plasma level. In plasma, more than 90% of these pro-drugs can change back to the drug in a few minutes. The prodrugs can be used medicinally in treating any ketoprofen and fenoprofen-treatable conditions in humans or animals. The prodrugs can be administered not only orally, but also transdermally for any kind of medical treatments and avoid most of the side effects of ketoprofen and fenoprofen, most notably GI disturbances such as dyspepsia, gastroduodenal bleeding, gastric ulcerations, and gastritis. Controlled transdermal administration systems of the prodrug enables ketoprofen and fenoprofen to reach constantly optimal therapeutic blood levels to increase effectiveness and reduce the side effects of ketoprofen and fenoprofen. Another great benefit of transdermal administration of these pro-drugs is that administering medication, especially to children, will be much easier.
    • 设计并合成了通式(1)“结构1”中酮洛芬和非诺洛芬的新型带正电荷的前药。 上述通式(1)'结构1'的化合物可以通过与合适的醇,硫醇或胺的反应由酮洛芬和非诺洛芬的功能衍生物(例如酰卤或混合酸酐)制备。 这些前药的带正电荷的氨基不仅大大增加了药物的溶解度,而且还与磷酸盐头基团上的负电荷键合,并将前药推入细胞溶质中。 结果表明,前药,2-(3-苯甲酰基苯基)丙酸二乙基氨基乙酯,AcOH和2-(3-苯氧基苯基)丙酸二乙基氨基乙酯。通过人皮肤扩散至酮洛芬和非诺洛芬的125倍。 口服口服酮洛芬或非诺洛芬时,需要1-2小时才能达到酮洛芬或非诺洛芬血药浓度,但2-(3-苯甲酰基苯基)丙酸二乙氨基乙酯。乙酸或二乙基氨基乙基2-(3-苯氧基苯基)丙酸酯。仅AcOH 花了约40分钟达到酮洛芬或非诺洛芬峰值血浆水平。 在血浆中,超过90%的这些前药可以在几分钟内恢复到药物。 前药可以在医学上用于治疗人或动物中的任何酮洛芬和非诺洛芬治疗性病症。 前药可以不仅口服给药,而且可以经皮用于任何种类的药物治疗,并避免酮洛芬和非诺洛芬的大部分副作用,最明显的是GI紊乱如消化不良,胃十二指肠出血,胃溃疡和胃炎。 前药的受控透皮给药系统使酮洛芬和非诺洛芬达到不断优化的治疗血液水平以增加效力并降低酮洛芬和非诺洛芬的副作用。 经皮给药这些前药的另一大好处是给予药物,尤其是给儿童服用药物将容易得多。
