The present invention relates to novel aminoalkylazoles acting as inhibitors of malarial protease plasmepsin II. These can be used as medicines or as constituent of medicines for the treatment of malaria infection.
The spread of drug‐resistant malariaparasites urges the search for new antimalarial drugs. Malarial asparticproteases – plasmepsins (Plms) – are differentially expressed in multiple stages of the Plasmodium parasite's lifecycle and are considered as attractive drug targets. We report the development of novel azole‐based non‐peptidomimetic plasmepsininhibitors that have been designed by bioisosteric
抗药性疟原虫的传播促使人们寻找新的抗疟药。疟疾天冬氨酸蛋白酶——血浆蛋白酶 (Plms)——在疟原虫生命周期的多个阶段有差异表达,被认为是有吸引力的药物靶点。我们报告了新型唑类非肽模拟血浆蛋白酶抑制剂的开发,该抑制剂是通过对 Actelion 氨基哌嗪抑制剂中的酰胺部分进行生物等排取代而设计的。最好的基于三唑的抑制剂对 Plm II 表现出亚微摩尔的效力,这与母体 Actelion 化合物相当。新抑制剂可作为开发无耐药性抗疟药的起点,靶向非消化性 Plm IX 或 X,这对疟原虫生命周期至关重要。
Synthesis of Carlina Oxide Analogues and Evaluation of Their Insecticidal Efficacy and Cytotoxicity
of exploring new synthetic routes for obtaining this compound and analogues with improved bioactivity and lower toxicity. Herein, the chemical synthesis of carlina oxide analogues was developed. Their insecticidal activity was assessed on the vectors Musca domestica L. and Culex quinquefasciatus Say, and their cytotoxicity was evaluated on a human keratinocyte cell line (HaCaT). The compounds’ activity

Visible light driven acridinium catalysed synthesis of dihydropyranopyrazole scaffolds from pyrazol and butyne derivatives under an air atmosphere is reported at room temperature. This synthetic process includes synthesis of desired product with excellent yield via C-C and C−O bond formation. This transition-metal-free organo-photoredox catalysed process accepts a wide range of functional groups tolerance
据报道,在室温下,可见光驱动的吖啶鎓催化在空气气氛下由吡唑和丁炔衍生物合成二氢吡喃吡唑支架。该合成过程包括通过 CC 和 C−O 键的形成以优异的产率合成所需的产物。这种不含过渡金属的有机光氧化还原催化过程接受广泛的官能团耐受性,并在高度环境友好的条件下生成二氢吡喃吡唑部分。
