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.

The present invention relates to novel compounds, particularly for use as additives in a lipidic cubic phase material, and to novel lipidic cubic phase materials. These materials are biocompatible, stable and transparent and can encapsulate active compounds such as drugs and release them at will by chemical and/or photochemical triggering. A method of controlled release of a predetermined active compound, comprises the steps of: forming a lipidic cubic phase material by mixing a lipophilic component and a hydrophilic component comprising an aqueous solution containing the active compound; placing the lipidic cubic phase material in a region of interest; releasing the active compound by subjecting the lipidic cubic phase material to a chemical or photochemical stimulus.
