Suplatast tosilate CAS:94055-76-2 is an antiallergic drug. Suplatast Tosylate inhibits antigen-induced histamine release from mast cells as well as IgE antibody formation. Suplatast Tosylate suppresses interleukin (IL)-4 release from T cells, however in human peripheral basophils, Suplatast Tosylate inhibited the antigen-induced release of IL-13 but not IL-4.
Suplatast tosilate CAS:94055-76-2 is a unique dimethylsulfonium salt marketed in Japan for the treatment of bronchial asthma, atopic dermatitis and allergic rhinitis. Suplatast tosylate is a potent inhibitor of IgE synthesis without suppressing IgM and IgG. The mechanism of action for suplatast tosylate is thought to be via the inhibition of interleukin-4 and interleukin-6 production by T-cells at the gene level. In allergic patients, suplatast tosylate markedly improved clinical symptoms which correlated with a significant decrease in serum IgE antibody levels.
Suplatast tosilate CAS:94055-76-2 could be supplied in different size with competitive price.
