Product Description
Gold derivative in clinical use as an anti-arthritic. Acts as an inhibitor of several leukocyte activation pathways. Inhibits release of inflammatory mediators from human macrophages, pulmonary mast cell and basophils. Also inhibits human neutrophil 5-lipoxygenase. Efficient inducer of mitochondrial membrane permeability transition pore in the presence of calcium ions, potentially referable to its inhibition of mitochondrial thioredoxin reductase.

Product Description
Antibiotic. Potent immunosuppressor. Widely used after organ transplantation. Binds to cytosolic proteins of the cyclophilin family. Cyclosporin A-cyclophilin complexes block protein phosphatase 2B (PP2B; calcineurin), a key enzyme in T cell activation. As a result of the calcineurin inhibition, cyclosporine A blocks various cellular processes such as activation of T cells and expression of several lymphokines (especially IL-2). Inhibits cytochrome c release from mitochondria. Inhibits nitric oxide (NO) synthesis.
