Mycobacterial glycolipid, trehalose-6, 6'-dimycolate (TDM), and its analogs, 6, 6'-di-O-triacontanoyl-α, α-trehalose [TD (L30)], 6, 6'-bis-O-(2-tetradecylhexadecanoyl)-α, α-trehalose [TD-(B30)], 6, 6'-bis-O-(3-hydroxy-2-tetradecyloctadecanoyl)-α, α-trehalose [TD (BH32)], 6, 6'-bis-O-(2-docosyl-3-hydroxyhexacosanoyl)-α, α-trehalose [TD (BH48)], 6, 6'-bis-O-(3-tetradecanoyloxy-tetradecanoyl)-α, α-trehalose [TD (D28)], 6, 6'-dideoxy-6, 6'-bis (mycoloylamino)-α, α-trehalose [TDNM] and 6, 6'-dideoxy-6, 6'-bis (3-hydroxy-2-tetradecyloctadecanoylamino)-α, α-trehalose [TDN (BH32)], were synthesized, and their lethal and adjuvant activities were examined. TDM and TDNM were lethal when injected intravenously into mice at a dose of 150 μg as 9% oil-in-water emulsion, but the other analogs showed no lethal toxicity to mice at the same dose. The cytolytic activity of mouse peritoneal macrophages against tumor cells was potentiated by intraperitoneal injection of TDM and its synthetic analogs. TDM and TD (BH32) also stimulated nonspecific host resistance against Sendai virus infection in BALB/c mice.
分枝杆菌糖脂,曲哈洛糖-6,6'-二甲氧基酸酯(TDM)及其类似物,6,6'-二-O-三碳酰基-α,α-曲哈洛糖[TD (L30)],6,6'-双-O-(2-十四烷基十六烷酰基)-α、6,6'-双-O-(3-羟基-2-十四烷基十八烷酰基)-α,α-三卤糖[TD-(B30)],6,6'-双-O-(2-二十二烷基-3-羟基二十六烷酰基)-α、6,6'-双-O-(2-二十二烷基-3-羟基二十六烷酰)-α,α-三卤糖[TD (BH48)],6,6'-双-O-(3-十四烷酰氧基-十四烷酰)-α,α-三卤糖[TD (D28)],6,6'-双脱氧-6,6'-双(霉菌酰氨基)-α,α-三卤糖[TDNM]和 6、合成了 6, 6'-dideoxy-6, 6'-bis (3-hydroxy-2-tetradecyloctadecanoylamino)-α, α-trehalose[TDN(BH32)],并检测了它们的致死活性和佐剂活性。当小鼠静脉注射剂量为 150 μg 的 9% 水包油型乳剂时,TDM 和 TDNM 具有致死性,但在相同剂量下,其他类似物对小鼠无致死毒性。腹腔注射 TDM 及其合成类似物可增强小鼠腹腔巨噬细胞对肿瘤细胞的细胞溶解活性。TDM 和 TD (BH32) 还能激发 BALB/c 小鼠对仙台病毒感染的非特异性宿主抵抗力。
