    摘要:
    在磷酸盐缓冲液(pH 7.4),大鼠血浆和大鼠组织匀浆中研究了普萘洛尔,O-乙酰基,O-丙酰基,O-丁酰基,O-新戊酰基和琥珀酰基酯的几种酯型前药水解的立体化学特征。在磷酸盐缓冲液中,在(R)-和(S)-普萘洛尔的酯之间的水解速率没有观察到差异。酯部分对在磷酸盐缓冲液中的水解速率的影响按以下顺序:乙酸盐>丙酸酯>丁酸酯>琥珀酸酯>新戊酸酯。在大鼠血浆和组织匀浆中,酯的水解被加速,并且观察到立体选择性水解。在血浆中,除了琥珀酸酯以外,(R)-异构体的水解比(S)-异构体的水解快。另一方面,在肝脏和肠的匀浆中,(S)-异构体的水解速度比(R)-异构体快,除了肝脏匀浆中的琥珀酸酯和新戊酸酯。而且,水解速率的比率(S / R)随前药的类型而变化。随着酯的烷基链长度的增加,肝脏中的S / R比值趋于统一,而肠的匀浆度却几乎保持恒定。对于新戊酸酯,在血浆和肠匀浆中观察到立体选择性水解,而在肝匀浆中未观

  • Stereoselective Hydrolysis of O-Acetyl Propranolol as Prodrug in Rat Tissue Homogenates
    作者:Koichi Takahashi、Satoko Tamagawa、Jun Haginaka、Hiroyuki Yasuda、Toyoshi Katagi、Nobuyasu Mlzuno
    DOI:10.1002/jps.2600810307
    日期:1992.3
    characteristics of the hydrolysis of O-acetyl propranolol were studied using phosphate buffer (pH 7.4), rat plasma, and rat tissue homogenates. In the phosphate buffer, no difference was observed in the hydrolysis rate between the esters of (R)- and (S)-propranolol. In rat plasma and tissue homogenates, hydrolysis of the ester was both accelerated and stereoselective. Hydrolysis of O-acetyl (R)-propranolol
    使用磷酸盐缓冲液(pH 7.4),大鼠血浆和大鼠组织匀浆研究了O-乙酰基普萘洛尔水解的立体化学特征。在磷酸盐缓冲液中,在(R)-和(S)-普萘洛尔的酯之间的水解速率没有观察到差异。在大鼠血浆和组织匀浆中,酯的水解既加速又立体选择性。在大鼠血浆中,O-乙酰基(R)-普萘洛尔的水解速度比(S)-异构体的水解快五倍。但是,在肝脏和肠匀浆中,(S)-异构体的水解速度比(R)-异构体快。在实验条件下未观察到(R)-和(S)-异构体之间的相互转化。外消旋的O-乙酰基普萘洛尔也观察到相同的立体选择性水解。然而,观察到的水解速率常数低于纯异构体。这些结果表明,O-乙酰基普萘洛尔的酶促水解是立体选择性发生的,血浆酶的选择性不同于肝和肠酶。
  • Acetylation of (R,S)-propranolol catalyzed by Candida antarctica lipase B: An experimental and computational study
    作者:Andrés M. Escorcia、Daniel Molina、Martha C. Daza、Markus Doerr

    The chemo- and enantioselectivity of the Candida antarctica lipase B (CalB)-catalyzed acetylation reaction of (R,S)-propranolol using vinyl acetate as acyl donor and toluene as organic solvent was studied. Because of the poor solubility of propranolol in toluene small quantities of methanol were added as cosolvent. The effects of the propranolol/vinyl acetate ratio, the enzyme purification procedure and the methanol concentration on the reaction were investigated. The reactions occurring in the system were quantitatively investigated using H-1 and C-13 NMR spectroscopy. The major reactions were the hydrolysis and alcoholysis of vinyl acetate, as a consequence of the presence of residual water and methanol in the reaction medium. Furthermore, the NMR analysis confirmed that O-acetyl-propranolol was formed exclusively. The reaction was also found to be enantioselective favoring the faster transformation of the R-propranolol. In addition to the experiments, molecular modeling was used to study the formation of the reactive Michaelis complexes between propranolol and acetylated CalB, using a combined molecular docking and molecular dynamics (MD) procedure. Only for the O-acetylation we found binding modes of the substrate leading to formation of the product, which explains the experimentally observed chemoselectivity of CalB. (C) 2013 Elsevier B.V.

    stereoselective hydrolysis of the succinate ester was observed only in intestine homogenate, but the S/R ratio was almost 1 in plasma, liver and intestine homogenates. No interconversion between (R)- and (S)-isomer was observed during the hydrolysis of any of the ester prodrugs. These results indicate that hydrolysis of ester-type prodrugs of propranolol occurs stereoselectively in rat tissues, and that
