examined for their ability to form complex high axial ratio microstructures (CHARMS), potential drug delivery vehicles. In general, if the modified ceramide had either a hydrogen bond donor or acceptor at C-1 and C-3, including hydrophobic or hydrophilic groups attached to C-1 microstructures formed. Tolerated groups include amides, esters, sulfonates, and ethers. If modification at C-3 added significant
制备了具有化学修饰的极性头基的神经酰胺,并检查了其形成复杂的高轴向比微结构(CHARMS)(潜在的药物递送载体)的能力。通常,如果改性的神经酰胺在C-1和C-3处具有氢键供体或受体,包括与形成的C-1微结构相连的疏水或亲水基团。容许的基团包括酰胺,酯,磺酸盐和醚。如果C-3处的修饰增加了大量的体积(大于4个碳原子,而与亲水性无关),则会形成无定形聚集体。具有通过循环结构桥接的C-1和C-3的神经酰胺也可形成微结构。通过使用具有胺头基的鞘脂,可以在形成后共价修饰CHARM。
