    摘要:
    描述了伯氨喹的咪唑啉丁-4-酮衍生物作为潜在的抗疟药的合成。在三个步骤中合成的目标化合物:(ⅰ)的缩合(±)-primaquine用N α -保护的氨基酸,(ⅱ)除去N-的α保护基团,和(iii)的N acylprimaquine与反应羰基化合物:丙酮,三个环酮和藜芦醛。在得到第三步骤,使用2-甲酰基苯甲酸1 H ^ -咪唑并[2,1-一个]异吲哚-2,5(3 ħ,9B ħ) -二酮。分离出的所有产物均具有良好的收率。咪唑啉丁-4-酮是所有可能的非对映异构体的等量混合物,而1 H-咪唑并[2,1-以立体选择性的方式产生]异吲哚-2,5(3 H,9b H)-二酮。化合物在pH 7.4缓冲液中水解非常缓慢(t 1/2 5–30 d),释放出伯氨喹。这些伯氨喹衍生物正在接受生物学检测,其抗疟活性的初步结果令人鼓舞。

    The synthesis of imidazolidin-4-one derivatives of primaquine containing the five-membered ring at the C-terminus of a dipeptide backbone coupled to the parent drug is described. These peptidomimetic derivatives were active against a chloroquine-resistant Plasmodium falciparum strain and inhibited the development of the sporogonic cycle of Plasmodium berghei, affecting the appearance of oocysts in
    描述了在与母体药物偶联的二肽主链的C末端含有五元环的伯氨喹的咪唑烷二-4-酮衍生物的合成。这些拟肽衍生物对抗氯喹的恶性疟原虫菌株具有活性,并抑制了伯氏疟原虫的孢子周期的发展,影响了蚊子中肠内卵囊的出现。由于N(1)的酰化作用,新型的咪唑烷基-4-酮在人血浆和pH 7.4缓冲液中都极为稳定。因此,衍生自二肽基8-氨基喹啉的“内部”咪唑啉丁-4-酮代表了抗疟疾结构-活性关系中的一个新条目。

    imidazolidin-4-one. The kinetically determined pKa values are ca. 3.6–4.0, i.e., 4 pKa units lower than those of amino acid amides, thus implying that hydrolysis of imidazolidin-4-ones at pH 7.4 involves the unionized form. Reactivity of this form decreases with the steric crowding of the amino acid α-substituent. In contrast, the rate constant for the spontaneous decomposition of the unionized form increases
    与基于肽的咪唑啉丁-4-酮相比,由抗疟疾药物的N-(α-氨基酰基)衍生物,伯氨喹和酮合成的那些在37°C的pH 7.4中出乎意料地稳定。在60°C的pH范围0.3–13.5下,研究了基于伯氨喹的咪唑啉丁-4-酮的水解动力学。水解成母体α-氨基酰基伯氨喹的特征是S形的pH速率分布,反映了咪唑烷二-4-酮的结合形式和质子化形式(在N-1下)的自发分解。动力学确定的p K a值为ca。3.6–4.0,即4 p K a单元比氨基酸酰胺的单元低,因此暗示在pH 7.4的咪唑烷基-4-酮的水解涉及联合形式。该形式的反应性随氨基酸α-取代基的空间拥挤而降低。与此相反,速率常数的非离子化形式急剧增加用于从环酮衍生的咪唑烷-4-酮,可由解释的观察自发分解余应变(内应变)的影响。这些结果与水解的涉及一个S的机制一致Ñ酰胺基离去后,咪唑啉丁-4-一C2-N3键的1型单分子裂解。在计算研究的支持下,质子化咪唑啉丁

    Imidazolidin-4-one derivatives of primaquine were synthesized as potential double prodrugs of the parent drug. The title compounds inhibit the development of the sporogonic cycle of Plasmodium berghei, affecting the appearance of oocysts in the midguts of the mosquitoes. The imidazolidin-4-ones are very stable, both in human plasma and in pH 7.4 buffer, indicating that they are active per se. Thus

    日期:2008.12
    The acylation of bioactive primaquine-based imidazolidin-4-ones was studied using Nα-Boc-protected glycine as acylating agent. Two synthesis routes, eight different coupling methods and seven distinct solvents were compared. Mild carbodiimide-based couplings on high dielectric constant solvents such as DMF or MeCN increased acylation yields, whereas alcohols inhibited carbodiimide-mediated acylations
    使用的生物活性基于伯-咪唑烷-4-酮的酰化进行了研究Ñ α -Boc保护的甘氨酸作为酰化剂。比较了两种合成路线,八种不同的偶联方法和七种不同的溶剂。在高介电常数溶剂(例如DMF或MeCN)上基于碳二亚胺的轻度偶联提高了酰化收率,而醇类则抑制了碳二亚胺介导的酰化反应。合成目标的实现受限于咪唑烷基-4-酮环取代基R 1,R 2和R 3的大小,但诉诸于MW辅助合成可以克服此类障碍,尽管反应收率非常适中。涉及所用Boc保护的氨基酸的所有反应均具有区域选择性,而与所采用的反应条件无关。相比之下,咪唑烷丁-4-酮的区域选择性乙酰化只能通过非常温和的偶联程序来实现。
  • Imidazoquines as Antimalarial and Antipneumocystis Agents

    Peptidomimetic imidazolidin-4-one derivatives of primaquine (imidazoquines) recently displayed in vitro activity against blood schizonts of a chloroquine-resistant strain of Plasmodium falciparum. Preliminary studies with a subset of such imidazoquines showed them to both block transmission of P. berghei malaria front mouse to mosquito and be highly stable toward hydrolysis at physiological conditions. This prompted Lis to have deeper insight into the activity of imidazoquines against both Plasmodia and Pneumocystis carinii, on which primaquine is also active. Full assessment of the in vivo transmission-blocking activity of imidazoquines, in vitro tissue-schizontocidal activity on P. berghei-infected hepatocytes, and in vitro anti-P. carinii activity is now reported. All compounds were active in these biological assays, with generally lower activity than the parent drug. However, imidazoquines' stability against both oxidative deamination and proteolytic degradation suggest that they will probably have higher oral bioavailability and lower hematotoxicity than primaquine, which might translate into higher therapeutic indexes.
