Cyclosporin H has been used:to pre-culture the lineage depleted murine Flt3ITDIDH2R140Q BM cells for transductionas a formyl peptide receptor (FPR) antagonist to study the role of FPR1 in calcium mobilization in polymorphonuclear leukocytes (PMNs)as one of the small molecules to study its effect on the homology-directed repair (HDR) editing efficiency in human-induced pluripotent stem cells (iPSCs) and T cells
Biochem/physiol Actions
Cyclosporin H is a selective inhibitor of formyl peptide receptor-1 (FPR-1) and formyl peptide-induced superoxide formation in neutrophils. Cyclosporin H does not bind cyclophilin or evoke an immunosuppressant response. Cyclosporin H has been reported to inhibit tumor promoting phorbol ester TPA/PMA in mouse skin cells and to inhibit calcium/calmodulin-dependent EF-2 phosphorylation.
