辛可卡因主要适用于硬膜外麻醉以及腰麻。本品容易通过粘膜，也用于表面麻醉，但因其毒性过大（约比普鲁卡因高15倍），较少用于浸润麻醉。
1、2-氯-N-[2-(二乙基氨基)乙基]-4-喹啉甲酰胺的合成
室温下向3000ml三口瓶中加入2-羟基-4-喹啉羧酸200g，甲苯1500ml搅拌下滴加氯化亚砜158g，升温至75℃反应2小时，降温至25℃，减压浓缩，再加500ml甲苯，继续减压浓缩至干，直接加入2000ml甲苯稀释后加入到5000ml三口瓶中，再加入N,N－二乙基二乙胺100g，升温70℃搅拌，反应完全后降至室温，加水搅拌30分钟，分液，有机层用水洗两次，饱和食盐水洗涤一次，无水硫酸钠干燥，过滤，滤液旋干，得2-氯-N-[2-(二乙基氨基)乙基]-4-喹啉甲酰胺即辛可酰胺274g，收率85％。
2.辛可卡因的合成
将200g辛可酰胺，550ml正丁醇和300g正丁醇钠加入至3000ml反应瓶中，逐渐升温至回流3小时后，降温至室温，加入纯化水1000ml，搅拌30分钟，静止分层30min，将水层弃去，有机层加入无水硫酸钠干燥，过滤，滤液减压浓缩，然后加入500ml甲苯并升温至60℃搅拌30min，静置，分层，上层甲苯层降温析晶，得辛可卡因精制品146g，收率65％,纯度为99.7％。
Dibucaine (Cinchocaine) reduces the degradation of BSA-gold complex in the reservosomes, which was not caused either by an inhibition of the whole proteolytic activity of the parasite or by a reduction on the expression levels of cruzipain. Dibucaine, a quaternary ammonium compound, inhibited SChE to a minimum within 2 min in a reversible manner. The inhibition was very potent. It had an IC(50) of 5.3 microM with BuTch or 3.8 microM with AcTch. The inhibition was competitive with respect to BuTch with a K(i) of 1.3 microM and a linear-mixed type (competitive/noncompetitive) with respect to AcTch with inhibition constants, K(i) and K(I) of 0.66 and 2.5 microM, respectively. Dibucaine possesses a butoxy side chain that is similar to the butryl group of BuTch and longer by an ethylene group from AcTch.
