Based on the physicochemical and pharmacological properties of drugs having an adamantane skeleton, an adamantane-based moiety was evaluated as a drug carrier for poorly absorbed compounds, including peptides, active towards the central nervous system (CNS). Seven [D-Ala2]Leu-enkephalin derivatives conjugated with an adamantane-based moiety at the C-terminus or N-terminus were prepared by the solution-phase
基于具有金刚烷骨架的药物的物理化学和药理特性,将基于金刚烷的部分评估为对中枢神经系统(CNS)具有活性的吸收不良的化合物(包括肽)的药物载体。通过溶液相法制备了七个在C末端或N末端与基于金刚烷的部分缀合的[D-Ala2] Leu-脑啡肽衍生物,并检查了它们的生物学活性。通过酯或酰胺键在C端衍生的化合物比亲本肽具有更大的亲脂性,并具有中等的体外阿片样物质活性(豚鼠回肠试验)。其中,四种衍生物(1、2、4、5)在皮下给药后的体内试验(小鼠尾压试验)中显示出显着的抗伤害感受作用。
