11-trans LTC4 is a C-11 double bond isomer of LTC4. LTC4 undergoes slow temperature-dependent isomerization to 11-trans LTC4 during storage. 11-trans LTC4 is produced in smaller amounts relative to LTC4 in ionophore-stimulated HMC-1 cells (a human mast cell line) and equine eosinophils, but not in…

11-trans LTD4 is a C-11 double bond isomer of LTD4. LTD4 undergoes slow temperature-dependent isomerization to 11-trans LTD4 during storage. 11-trans LTD4 retains about 10-25 % of the potency for contraction of guinea pig ileum, trachea and parenchyma compared to LTD4. It exhibits an ED50 ranging…
