  摘要：

  合成肽R2N-COCH2OCH2CO-Gly-Gly-Gly-Pro-Gly-Gly-Gly-OR′在R为n-十八烷基且R′为苄基时，对Cl−相对于K+表现出选择性。目前已制备出十九种七肽，其中N端和C端残基有所不同。所有N端残基均为二烷基，而C端链为酯、二级酰胺或三级酰胺。N端锚和C端苄基不同的化合物如下：1，R = n-丙基；2，R = n-己基；3，R = n-戊基；4，R = n-癸基；5，R = n-十二烷基；6，R = n-十四烷基；7，R = n-十六烷基；8，R = n-十八烷基。化合物9–19中R = n-十八烷基，C端残基如下：9，OR′ = OCH2CH3；10，OR′ = OCH(CH3)2；11，OR′ = O(CH2)6CH3；12，OR′ = OCH2–c-C6H11；13，OR′ = O(CH2)9CH3；14，OR′ = O(CH2)17CH3；15，NR′2 = N[(CH2)6CH3]2；16，NHR′ = NH(CH2)9CH3；17，NR′2 = N[(CH2)9CH3]2；18，NHR′ = NH(CH2)17CH3；19，NR′2 = N[(CH2)17CH3]2。观察到的最高阴离子转运活性如下：对于N端残基变量的苄基酯，i.e.1–8，化合物3活性最强。对于C18锚定的酯10–14，n-庚基酯11活性最强。对于C18锚定的C端酰胺15–19，二-n-癸酰胺17活性最强。结论是C端和N端锚对双层膜中的通道功能十分重要，但只有其中一个锚定基团占主导时活性才存在。

  The synthetic peptide, R2N-COCH2OCH2CO-Gly-Gly-Gly-Pro-Gly-Gly-Gly-OR′, was shown to be selective for Cl− over K+ when R is n-octadecyl and R′ is benzyl. Nineteen heptapeptides have now been prepared in which the N-terminal and C-terminal residues have been varied. All of the N-terminal residues are dialkyl but the C-terminal chains are esters, 2° amides, or 3° amides. The compounds having varied N-terminal anchors and C-terminal benzyl groups are as follows: 1, R = n-propyl; 2, R = n-hexyl; 3, R = n-octyl; 4, R = n-decyl; 5, R = n-dodecyl; 6, R = n-tetradecyl; 7, R = n-hexadecyl; 8, R = n-octadecyl. Compounds 9–19 have R = n-octadecyl and C-terminal residues as follows: 9, OR′ = OCH2CH3; 10, OR′ = OCH(CH3)2; 11, OR′ = O(CH2)6CH3; 12, OR′ = OCH2–c-C6H11; 13, OR′ = O(CH2)9CH3; 14, OR′ = O(CH2)17CH3; 15, NR′2 = N[(CH2)6CH3]2; 16, NHR′ = NH(CH2)9CH3; 17, NR′2 = N[(CH2)9CH3]2; 18, NHR′ = NH(CH2)17CH3; 19, NR′2 = N[(CH2)17CH3]2. The highest anion transport activities were observed as follows. For the benzyl esters whose N-terminal residues were varied, i.e.1–8, compound 3 was most active. For the C18 anchored esters 10–14, n-heptyl ester 11 was most active. For the C18 anchored, C-terminal amides 15–19, di-n-decylamide 17 was most active. It was concluded that both the C-and N-terminal anchors were important for channel function in the bilayer but that activity was lost unless only one of the two anchoring groups was dominant.
