摘 要:吡咯烷衍生物與環(huán)氧環(huán)戊烷開(kāi)環(huán)反應后,與3,4-二甲氧基苯乙氧基中間體對接,再經(jīng)鈀碳加氫脫保護得維納卡蘭類(lèi)似物,并通過(guò)全細胞膜片鉗技術(shù),探討其對Kv 1.5鉀通道電流的阻斷效果。結果顯示,類(lèi)似物1a、1b和1c抑制Kv1.5鉀通道的IC50分別為sustain current:37,77,30;peak current:89,389,157 (μM),且呈濃度和時(shí)間依賴(lài)性。 |

Abstract:The Vernakalant analogues were synthesized through a series reactions including using pyrrolidine derivatives reaction with epoxy cyclopentane by ring-opening reaction, coupling reaction with 3,4-dimethoxyphenethyl alcohol intermediate, and followed by deprotection reaction by Pd/C-H2. The blockade activity against Kv1.5 potassium channel were evaluated using the whole-cell patch clamp technique. The results showeda significant dose and time dependent block on Kv 1.5 potassium channel. The IC50 of analogues 1a, 1b and 1c of sustain current were37, 77,and 30, respectively; peak current were 89, 389, and 157 (μM) respectively. |
Key words:Vernakalant; analogue; Kv 1.5 potassium channel |
