Leukotrienes B4, C4, D4 and E4 are conjugated with various proteins, viz. Bovine Serum Albumin, Hemocyanin from Giant Keyhole Limpets, human serum albumin, tetanus antigen, diphtheriae toxoid and CRM 197 using 1,5-difluoro-2,4-dinitrobenzene or 6-N-maleimido(C2-8 alkanoic acid)-chloride as coupling agent.
These conjugates are useful as reagents in a newly developed immunoassay for leukotrienes, as well as having potential utility as chemical immunotherapeutic agents in the treatment of various allergic and chronic inflammatory diseases of the skin, lung, and airways, including asthma, allergic rhinitis, rheumatoid arthritis, and skin diseases such as psoriasis and eczema. They may be made into pharmaceutical compositions.
Certain novel intermediate compounds are also provided.
白三烯 B4、C4、D4 和 E4 以 1,5-二氟-2,4-二硝基苯或 6-N-马来酰亚胺基(C2-8 烷酸)-盐酸盐为偶联剂,与各种蛋白质(即牛血清白蛋白、巨匙孔蛙的血蓝蛋白、人血清白蛋白、破伤风抗原、白喉类毒素和 CRM 197)共轭。
这些共轭物可用作新开发的白三烯免疫测定试剂,也可用作化学免疫治疗剂,用于治疗皮肤、肺部和呼吸道的各种过敏性和慢性炎症性疾病,包括哮喘、过敏性鼻炎、类风湿性关节炎以及牛皮癣和湿疹等皮肤病。它们可以制成药物组合物。
还提供了某些新型中间体化合物。
