The derivatives synthesized were tested for their ability to form stable monomolecular films at the air/water interface by recording their surface pressure/molecular area compression isotherms. The inhibition of human pancreatic and gastric lipases by the bis-2-oxo amides was studied using the monolayer technique with mixed films of 1,2-dicaprin containing variable proportions of each inhibitor.

开发了一种新型的有效人胃脂肪酶抑制剂,即双-2-氧代酰胺三酰基甘油类似物。从1,3-二氨基丙烷-2-醇开始制备脂肪酶天然底物的这些类似物。它们被设计为包含2-氧代酰胺官能团,而不是在sn-1和sn-3位置的易裂酸酯键,而在sn-2位置的酯键则保持不变或被醚键取代。通过记录其表面压力/分子面积压缩等温线,测试了合成衍生物在空气/水界面形成稳定单分子膜的能力。使用含有不同比例的每种抑制剂的1,2-二癸酸酯混合膜的单层技术研究了双-2-氧代酰胺对人胰腺和胃脂肪酶的抑制作用。sn-2位置上的官能团(酯或醚)的性质以及链长会影响抑制效果。在测试的化合物中,癸酸2-[((2-氧己基癸酰基)氨基] -1-[[(2-氧代十六烷酰基)-氨基]甲基]乙基癸酸酯是最有效的抑制剂,在0.076时,HPL和HGL活性降低50%和0.020表面摩尔分数。
