  具有强体外抗疟活性的新型氨基醇喹啉的设计、合成和表征

  摘要：

  疟疾是世界上第五大致命的寄生虫感染。在此，设计、合成了五个新系列的氨基醇喹啉，包括 52 种化合物，并在体外针对Pf 3D7 和Pf W2 菌株进行了评估。其中，14 株的 IC 50值低于或接近 50.0 nM，无论选择性指数通常高于 100 的菌株。发现17b是一种有希望的抗疟候选药物，对Pf 3D7 和Pf的 IC 50值分别为 14.9 nM 和 11.0 nMW2 和高于 770 的选择性指数，无论细胞系是什么。在对伯氏疟原虫ANKA 感染的小鼠模型进行体内研究之前，进行了进一步的实验以确认安全性并建立化合物17b的初步 ADMET 谱。该研究的总体数据允许建立新的结构-活性关系并开发具有改进药代动力学特性的新型药物。

  Mefloquine derivatives, contrary to chloroquine derivatives have not been widely studied to date. Consequently, mefloquine and its derivatives still remain very attractive synthetic targets. Although mefloquine is usually used clinically as a racemic mixture, some studies have shown that its (+)-enantiomer is more potent than the (-)-enantiomer. Moreover, the (-)-enantiomer is responsible for side effects due to reaction with the central nervous system adenosine receptors, while the (+)-enantiomer does no bind at this binding site. Recently, different libraries of racemate 4-aminoalcoholquinolines showed interesting anti-malarial activities. Herein, the present invention describes an enantiopure synthetic and straightforward route to prepare pure enantiomer 4-aminoalcoholquinoline derivatives through the 4-oxirane key-intermediate. A regioselective SN2 ring opening of this epoxide, by diverse amines, allows to obtain the corresponding (R) or (S) 4-aminoquinolines with good yields and enantiomeric excesses generally superior to 92%. The reported methodology appears suitable for the synthesis of a large number of pure enantiomer 4-aminoalcoholquinoline derivatives.

  梅氟喹诺酮衍生物与氯喹诺酮衍生物相比，迄今为止尚未广泛研究。因此，梅氟喹诺酮及其衍生物仍然是非常有吸引力的合成目标。虽然梅氟喹诺酮通常作为外消旋混合物在临床上使用，但一些研究表明其（+）-对映体比（-）-对映体更有效。此外，（-）-对映体由于与中枢神经系统腺苷受体的反应而导致副作用，而（+）-对映体则不会在该结合位点结合。最近，不同的外消旋4-氨基醇喹啉库显示出有趣的抗疟活性。在此，本发明描述了一种对映纯的合成和直接的途径，通过4-环氧丙烷关键中间体制备纯对映体4-氨基醇喹啉衍生物。通过多种胺的区域选择性SN2环开放该环氧化物，可以获得相应的（R）或（S）4-氨基喹啉，并且收率和对映体过量通常高于92％。所报告的方法适用于合成大量对映纯的4-氨基醇喹啉衍生物。

  A library of diamine quinoline methanols were designed based on the mefloquine scaffold. The systematic variation of the 4-position amino alcohol side chain led to analogues that maintained potency while reducing accumulation in the central nervous system (CNS). Although the mechanism of action remains elusive, these data indicate that the 4-position side chain is critical for activity and that potency (as measured by IC(90)) does not correlate with accumulation in the CNS. A new lead compound, (S)-1-(2,8-bis(trifluoromethyl)quinolin-4-yl)-2-(2-(cyclopropylamino)ethylamino)ethanol (WR621308), was identified with single dose efficacy and substantially lower permeability across MDCK cell monolayers than mefloquine. This compound could be appropriate for intermittent preventative treatment (IPTx) indications or other malaria treatments currently approved for mefloquine.
