制备方法与用途

应用

1-BOC-(2S,6R)-2,6-二甲基哌嗪是一种常用的药物设计片段。该化合物可通过以下步骤制备:

制备 步骤 1:(3S,5R)-3,5-二甲基哌嗪-1-甲酸苄酯

将 (2S,6R)-2,6-二甲基哌嗪(10.000g,87.573mmol)和三乙胺(18.309mL,131.360mmol)溶解于 300 mL 的二氯甲烷中,在 0℃下与氯甲酸苄酯(13.752mL,96.331mmol)混合,并在相同温度下搅拌 2 小时。随后添加饱和碳酸氢钾水溶液并用二氯甲烷萃取。有机层用饱和氯化钠水溶液洗涤、干燥 (MgSO₄),过滤并在真空下浓缩。产物未经进一步纯化,获得浅黄色油状物(11.000g,50.6%)。

步骤 2:4-苄基1-叔丁基(2R,6S)-2,6-二甲基哌嗪-1,4-二甲酸酯

在室温下将 (3S,5R)-3,5-二甲基哌嗪-1-甲酸苄酯(11.000g,44.296mmol)、二碳酸二叔丁酯(10.634g,48.725mmol)和三乙胺(9.261mL,66.444mmol)溶解于 300 mL 的二氯甲烷中,并在相同温度下搅拌 18 小时。添加水后用二氯甲烷萃取。有机层用饱和氯化钠水溶液洗涤、干燥 (MgSO₄),过滤并在真空下浓缩。将浓缩物通过柱色谱法纯化(SiO₂,12g 筒;乙酸乙酯/己烷 = 0% 至 20%),获得浅黄色油状物的4-苄基1-叔丁基(2R,6S)-2,6-二甲基哌嗪-1,4-二甲酸酯(6.350g,41.2%)。

步骤 3:1-BOC-(2S,6R)-2,6-二甲基哌嗪

向 4-苄基1-叔丁基(2R,6S)-2,6-二甲基哌嗪-1,4-二甲酸酯(6.350g,18.224mmol)的乙醇(150mL)溶液中缓慢滴加 10% Pd/C(1g)。将反应混合物在相同温度下、氢气氛围(H₂ 气球)下搅拌 17 小时。经硅藻土垫过滤去除固体,并在减压下浓缩。产物未经进一步纯化,获得黄色油状物的 (2R,6S)-2,6-二甲基哌嗪-1-甲酸叔丁酯(3.820g,97.8%)。

    名称:
    Antimalarial Lead-Optimization Studies on a 2,6-Imidazopyridine Series within a Constrained Chemical Space To Circumvent Atypical Dose–Response Curves against Multidrug Resistant Parasite Strains
    摘要:
    A lead-optimization program around a 2,6-imidazopyridine scaffold was initiated based on the two early lead compounds, 1 and 2, that were shown to be efficacious in an in vivo humanized Plasmodium falciparum NODscidIL2R gamma null mouse malaria infection model. The observation of atypical dose-response curves when some compounds were tested against multidrug resistant malaria parasite strains guided the optimization process to define a chemical space that led to typical sigmoidal dose-response and complete kill of multidrug resistant parasites. After a structure and property analysis identified such a chemical space, compounds were prepared that displayed suitable activity, ADME, and safety profiles with respect to cytotoxicity and hERG inhibition.
