2-butylglycerol, and/or 2-methyl fatty acids were synthesized. The triacylglycerol analogues 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 sterically hindered triacylglycerol analogues was studied by using the monolayer
已经开发了新型的人类消化脂肪酶抑制剂。合成了各种基于2-甲基和2-丁基甘油和/或2-甲基脂肪酸的空间位阻三酰基甘油。通过记录三酰基甘油类似物的表面压力/分子面积等温线,测试了它们在空气/水界面形成稳定单分子膜的能力。通过使用具有1,2-二癸酸酯混合膜的单层技术研究了空间受阻的三酰基甘油类似物对人胰腺和胃脂肪酶的抑制作用,其中每种抑制剂的含量各不相同。在甘油主链2位上含有丁基或在甘油2位上均含有甲基的三油精类似物,每个油酸残基的α位是有效的抑制剂。这导致0.003摩尔分数的HPL活性降低了50%。
