The ciclosporin analogue ciclosporin H is a potent and selective inhibitor of mediator release from basophils induced by activation of the formyl peptide receptor, and therefore has potential as an anti-inflammatory agent. It acts by interfering with agonist binding to formylmethionylleucylphenylalanine (FMLP) receptors. Unlike ciclosporin [ciclosporin A], ciclosporin H has Dmethyl valine (rather than the Lisomer) at position 11, has an extremely low affinity for cyclophilin, and is devoid of immunosuppressive activity. Ciclosporin H was undergoing preclinical investigation with researchers at the University of Naples Federico II in Italy as an antiinflammatory agent. However, no recent development has been reported.

In Vitro Use Guide

Ciclosporin H activity was determined in calcium imaging assay. HL-60 cells and HEL cells were incubated for 3 min with or without ciclosporin H before the addition of agonist N-Formyl-Met-Leu-Phe (FMLP). Ciclosporin H inhibited the stimulatory effects of FMLP on cytosolic Ca2+ concentration with Ki values of 0.08 mkM
