    • An encapsulation system for use in the treatment of diabetes (Types 1 or 2, and LADA) are provided. The system has (1 ) a delivery vehicle comprising a selectively permeable membrane that allows passage of glucose, insulin and other nutrients through the membrane, but prevents large molecules such as antibodies or inflammatory cells from passing through the membrane; (2) a population of islet cells or insulin producing cells encapsulated by said membrane; and (3) a biological response modifier that may be in contact with the membrane or encapsulated by the membrane. Generally, the biological response modifier is a compound, including resolved enantiomers, diastereomers, tautomers, salts and solvates thereof, having the following formula: wherein: X, Y and Z are independently selected from a member of the group consisting of C(R 3 ), N, N(R 3 ) and S; R 1 is selected from a member of the group consisting of hydrogen, methyl, C (5-9) alkyl, C (5-9) alkenyl, C (5-9) alkynyl, C (5-9) hydroxyalkyl, C (3-8) alkoxyl, C (5-9) alkoxyalkyl, the R 1 being optionally substituted; R 2 and R 3 are independently selected from a member of the group consisting of hydrogen, halo, oxo, C (1-20) alkyl, C (1-20) hydroxyalkyl, C (1-20) thioalkyl, C (1-20) alkylamino, C (1-20) alkylaminoalkyl, C (1-20) aminoalkyl, C (1-20) aminoalkoxyalkenyl, C (1-20) aminoalkoxyalkynyl, C (1-20) diaminoalkyl, C (1-20) triaminoalkyl, C (1-20) tetraaminoalkyl, C (5-15) aminothalkoxyamino, C (1-20) alkylamido, C (1-20) alkylamidoalkyl, C (1-20) amidoalkyl, C (1-20) acetamidoalkyl, C (1-20) alkenyl, C (1-20) alkynyl, C (3-8) alkoxyl, C (1-11) alkoxyalkyl, and C (1-20) dialkoxyalkyl.
    • 提供了一种用于治疗糖尿病的包封系统(1型或2型和LADA型)。 该系统具有(1)包含选择性渗透膜的输送载体,其允许葡萄糖,胰岛素和其它营养物通过膜,但是阻止大分子例如抗体或炎性细胞通过膜; (2)由所述膜包封的胰岛细胞群体或产生胰岛素的细胞群; 和(3)可以与膜接触或被膜包封的生物反应调节剂。 通常,生物反应调节剂是具有下列结构式的拆分的对映异构体,非对映异构体,互变异构体,盐和溶剂化物的化合物:其中:X,Y和Z独立地选自C(R' 3,N,N(R 3)和S; R 1选自氢,甲基,C(5-9) - 烷基,C(5-9)烷氧基烷基,R 1'是任选被取代的; R 2和R 3独立地选自氢,卤代,氧代,C 1〜(1-20)烷基, ,(1-20)羟基烷基,C 1-20(1-20)个硫代烷基,C(1-20) - 烷基氨基,C 1 -C 20 - (1-20)烷基氨基烷基,C(1-20)氨基烷基,C(1-20)氨基烷氧基烯基,C 1-20(1-20) (1-20)二氨基烷基,C 1-20(1-20)三氨基烷基,C(1-20)四氨基烷基 ,(5-15)氨基硫烷基氨基,C 1-20(1-20)烷基酰氨基,C(1-20) - 烷基酰氨基烷基,C 1 -C 20 - (1-20)酰氨基烷基,C 1-20(1-20),酰胺基烷基,C 1-20(1-20)烯基,C 1-20(1-20) (1-3)烷氧基,C(1-11)烷氧基烷基和C(1-20) - 炔基, 二烷氧基。
