The present invention relates to novel hydroxy functionalized 1, 2, 4-trioxanes of general formula (7) useful as antimalarial agents. This invention also relates to a process for the preparation of novel hydroxy functionalized 1, 2, 4- trioxanes and their derivatives. More particularly the present invention provides a process for the preparation of hydroxy functionalized 1, 2, 4-trioxanes and their derivatives of general formula (7) wherein R1 and R2 represents methyl, or part of a cyclic system such as cyclopentane, cyclohexane, cycloheptane, adamantane and A is a spacer such as oxygen substituted aromatic moieties and R3 is CH2CH2OH or CH2CH2OCOCH2CH2COOH.These novel hydroxy functionalized 1, 2, 4-trioxanes and their derivatives of general formula (7) are new compounds and are useful as antimalarial agents. These compounds have been tested against multi-drug resistant malaria in mice and have shown promising antimalarial activity. This invention, thus relates to pharmaceutical industry.
本发明涉及一类新型的羟基功能化1,2,4-三氧杂环己烷,其通用公式为(7),可用作抗疟疾剂。本发明还涉及一种用于制备新型羟基功能化1,2,4-三氧杂环己烷及其衍生物的方法。特别是,本发明提供了一种用于制备通用公式(7)的羟基功能化1,2,4-三氧杂环己烷及其衍生物的过程,其中R1和R2代表甲基,或环状系统的一部分,如环戊烷、环己烷、环庚烷、金刚烷,A是如氧代芳香基团之类的间隔基,R3是CH2CH2OH或CH2CH2OCOCH2CH2COOH。这些新型的羟基功能化1,2,4-三氧杂环己烷及其衍生物是新的化合物,可用作抗疟疾剂。这些化合物已在小鼠中对多药耐药疟疾进行了测试,并显示出有前途的抗疟疾活性。因此,本发明涉及制药工业。
