    • 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(R3), N, N(R3) and S; R1 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 R1 being optionally substituted; R2 and R3 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)aminotrialkoxyamino, 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(R3) ,N,N(R3)和S; R 1选自氢,甲基,C(5-9)烷基,C(5-9)烯基,C(5-9)炔基,C(5-9)羟基烷基,C(3) -8)烷氧基,C(5-9)烷氧基烷基,R1任选被取代; R 2和R 3独立地选自氢,卤素,氧代,C(1-20)烷基,C(1-20)羟基烷基,C(1-20)硫代烷基,C(1-20) 烷基氨基,C(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)氨基烷氧基炔基,C(1-20)二氨基烷基,C(1-20) C 1-20 1-20烷基氨基烷基,C(1-20)烷基氨基烷基,C(1-20)氨基烷基,C(1-20)乙酰氨基烷基,C(1-20) 1-20)烯基,C(1-20)炔基,C(3-8)烷氧基,C(1-11)烷氧基烷基和C(1-20)二烷氧基烷基。
