説明

Immunoglobulin G (IgG) is an important protein in humoral immunity. After IgG binds to the specific foreign antigen, IgG-antigen complexes are eliminated either by making it easier for a phagocytic cell to ingest them or by activating a complement system. We found that the carboxyamidemethylated subfragments obtained from human serum IgG by reduction and alkylation of its interchain disulfide bonds, have anti-ulcerogenic, anti-inflammatory and antiallergic activities, while no activity was recognized in the original IgG. On the other hand, some saturated and unsaturated fatty acids generally existing in microorganisms were found to have anti-inflammatory and anti-ulcerogenic activities. As the application of these researches, we synthesized hybrid compounds from sulfur-containing amines and fatty acids to make a lead compound for developing a new medicine. In this review, the experimental process will be discussed.
