new fatty N-acylaminoacids and N-acylamino esters from the C16:0, C18:0, C18:1, and C18:1(OH) fatty acid families and demonstrates the activity of these compounds as organogel agents. Compounds were heated and dissolved in various solvents (n-hexane, toluene, and gasoline). Only saturated C16:0 and C18:0 derived from alanine were able to form gels in toluene, and saturated C16:0 derived from phenylalanine

A series of novel lipids with designed functionalities were synthesized. These lipids are based on conjugation of alpha-amino acids and their esters, cationic, anionic, neutral, and photochromic moieties to the lipophilic 9-cis octadecenyl chains by amide, ester, thioester, or amine bonds. Because of the plasticity of lipidic cubic phases, it is envisaged that when mixed with monooleoyl-rac-glycerol (monoolein, MO) and water at appropriate proportions, they would assemble to form bicontinuous lipidic cubic phases (LCPs) that exhibit the well-known material properties of LCPs such as phase stability, optical transparency, and chemical permeability. Moreover, due to the nature and position of the functionality at the headgroup region, we envision them to perform as functional materials by design.

Inhibitors that target the glycinetransporter2, GlyT2, show promise as analgesics, but may be limited by their toxicity through complete or irreversible binding. Acyl-glycine inhibitors, however, are selective for GlyT2 and have been shown to provide analgesia in animal models of pain with minimal side effects, but are comparatively weak GlyT2 inhibitors. Here, we modify the simple acyl-glycine by
靶向甘氨酸转运蛋白 2、GlyT2 的抑制剂显示出作为镇痛剂的前景,但可能会通过完全或不可逆的结合而受到毒性的限制。然而,酰基甘氨酸抑制剂对 GlyT2 具有选择性,并且已被证明可在动物疼痛模型中提供镇痛作用,且副作用最小,但 GlyT2 抑制剂的作用相对较弱。在这里,我们通过合成具有一系列 l 和 d 构型的氨基酸头基的脂质类似物来修饰简单的酰基甘氨酸,以产生纳摩尔亲和力的选择性 GlyT2 抑制剂。强效抑制剂油酰-d-赖氨酸 (33) 对人和大鼠血浆和肝微粒体的降解也具有抗性,并且在大鼠腹腔注射后迅速吸收并容易穿过血脑屏障。
