    The present invention relates to novel compounds that are inhibitors of wild type and mutant dihydrofolate reductase (DHFR) of Plasmodium falciparum , which are useful for the treatment of malaria. It also relates to processes of making and using such compounds. The antimalarial compounds of the present invention have low toxicity to a host infected with the malarial parasite, and are potent when administered in pharmaceutical compositions.
    本发明涉及一种新型化合物,它们是疟原虫(Plasmodium falciparum)的野生型和突变型二氢叶酸还原酶(DHFR)的抑制剂,可用于治疗疟疾。本发明还涉及制备和使用这种化合物的方法。本发明的抗疟化合物对感染疟疾寄生虫的宿主毒性低,当以药物组合剂形式给药时具有强效。

    a single molecule, which are effective against both wild-type and multiple mutants of P. falciparum through their selective target binding, as demonstrated by X-ray crystallography. Furthermore, the hybrid inhibitors can forestall the emergence of new resistant mutants, as shown by selection of mutants resistant to hybrid compound BT1 from a diverse PfDHFR random mutant library expressed in a surrogate
    二氢叶酸还原酶(DHFR)的S108N突变使恶性疟原虫疟原虫通过与抑制剂的刚性侧链发生空间冲突而对乙胺嘧啶具有抗性。具有柔性侧链的抑制剂可以避免这种冲突并保持针对突变体的有效性。但是,其他突变(例如N108S还原)赋予了对柔性抑制剂的抗性。我们设计并合成了在单个分子中具有两种结构类型的杂化抑制剂,通过X射线晶体学证明,该抑制剂通过选择性结合靶点可有效对抗野生型和恶性疟原虫的多个突变体。此外,杂种抑制剂可以阻止新的抗性突变体的出现,如对杂种化合物具有抗性的突变体的选择所示来自替代细菌系统中表达的多种PfDHFR随机突变体文库中的BT1。这些结果表明,有可能开发出有效的抗叶酸抗疟疾药物,其寄生虫抗性突变的范围将大大减少。

    The present invention is anti-folate antimalarials with dual-binding modes of the general formula (I) [refer to structure in the abstract] wherein R 1 and R 2 which may be the same or different are independently selected from methyl or ethyl or alkyl-phenyl, R 3 is independently hydrogen, halide, lower alkyl substituted with ester, carboxylic, amide, and ether. Linker is X(CH 2 )nY wherein X and Y which may be the same or different are independently selected from oxygen, carbon, nitrogen, substituted phenyl where n is an integer from 1 to 2-6, or pharmaceutically acceptable salts therefore. The anti-folate antimalarials with dual-binding modes act as novel inhibitors with good inhibition constants against wild-type, double (C59R+SIOSN), triple (N51+C59R+SIOSN, C59R+S 1 OSN+I164L), and quadruple (N51+C59R+S108N+I164L) mutant enzymes. The compounds are also effective against wild type (Tm4/S.2) and mutants (K1CB1, W2, Cs1-2 and V1/S) malaria parasites.
