Description
 The cyclosporins are a group of macrolide immunosuppressants isolated from fungi.  They are researched for their use in prevention of post-transplant graft rejection.  Their mechanism of action involves suppression of cytotoxic T-cell maturation and activity by binding lymphocyte protein cyclophilin. Cyclophilin and cyclosporin form a complex targeting calcineurin, which is responsible for activating T-lymphocytes.  Additionally, the cyclosporins are researched for their ability to prevent damage to normal functioning cells in autoimmune disorders. 
  Cyclosporin B is  soluble in DMSO and ethyl alcohol.
