9-(1, 3-Dihydroxy-2-propoxymethyl) quanine and 9-(2, 3-dihydroxy-1-propoxymethyl) guanine have been found to have potent anti-viral activity against herpes viruses. These compounds, their acyl derivatieves, their phosphate derivatives and their pharmaceutically acceptable salts, phar-- maceutical formulations containing these compounds, the treatment of DNA viral or herpes viral infections with these compounds, methods of preparing these compounds, and novel intermediates useful in their preparation are all disclosed.
The compounds may be prepared by reaction of the appropriate acetoxymethyl ether with diacetyl-quanine, followed by deprotection. The acetoxymethyl ethers may be obtained by reaction of glycerol formal with acetic anhydride in the presence of a catalyst.
9-(1,3-二羟基-2-丙氧基甲基)鸟嘌呤和9-(2,3-二羟基-1-丙氧基甲基)鸟嘌呤已被发现对疱疹病毒具有很强的抗病毒活性。 本文公开了这些化合物、它们的酰基衍生物、它们的磷酸衍生物和它们的药学上可接受的盐、含有这些化合物的药物制剂、用这些化合物治疗DNA病毒或疱疹病毒感染、制备这些化合物的方法以及用于制备这些化合物的新型中间体。 这些化合物可以通过适当的乙酰氧甲基醚与二乙酰基鸟嘌呤反应,然后进行脱保护来制备。 乙酰氧甲基醚可以通过甘油醛与乙酸酐在催化剂存在下反应来获得。
