Passive gastrointestinal absorption and membrane retention of twelve esters of (S,S)-ethylenediamine-N,N'-di-2-(3-cyclohexyl)propanoic acid (EDCP) and (S,S)-1,3-propanediamine-N,N'-di-2-(3-cyclohexyl)propanoic acid (PDCP), as well as of these two non-esterified acids were estimated using PAMPA test. Artificial PAMPA membrane used in this study for the simulation of gastrointestinal barrier was solution of egg lecithin in dodecane (1 % w/v). All tested compounds belong to class III (high membrane retention and low permeation), whereas EDCP, dipentyl ester of PDCP (DPE-PDCP) and diisopentyl ester of PDCP (DIPE-PDCP) belong to class I (negligible membrane retention and low permeation). Finally, quantitative structure - permeability and structure - retention relationships models were created in order to find quantitative relationships between physico-chemical properties of tested compounds and PAMPA membrane permeability/membrane retention parameters. Statistically the most reliable models were analysed and used for the design of new compounds for which favourable membrane permeability and retention can be expected.

使用PAMPA测试,乙二胺-N,N'-二-2-(3-环己基)丙酸和1,3-丙二胺-N的定量结构-渗透率和定量结构-保留关系分析估算被动胃肠道吸收和膜保留,N′-二-2-(3-环己基)丙酸衍生物。

(S,S)-乙二胺-N,N'-二-2-(3-环己基)丙酸(EDCP)和(S,S)-1,3-丙二胺-十二种酯的被动胃肠吸收和膜保留使用PAMPA测试估算N,N'-二-2-(3-环己基)丙酸(PDCP)以及这两种非酯化酸。本研究中用于模拟胃肠道屏障的人造PAMPA膜是卵磷脂在十二烷中的溶液(1%w / v)。所有测试的化合物均属于III类(高膜保留率和低渗透性),而EDCP,PDCP的二戊酯(DPE-PDCP)和PDCP的二异戊酯(DIPE-PDCP)则属于I类(膜保留率低和低渗透性) 。最后,建立定量结构-渗透性和结构-保留关系模型,以找到被测化合物的理化性质与PAMPA膜渗透性/膜保留参数之间的定量关系。统计上,对最可靠的模型进行了分析,并将其用于新化合物的设计,可以预期这些化合物具有良好的膜渗透性和保留能力。
