N2 - To define the potency order of the leukotrienes for inhibition of [3H] leukotriene D4 and [3H]leukotriene C4 binding, we investigated leukotriene C4, D4 and E4 competition with and without the serine-borate complex in guinea pig lung and brain homogenates. Without it, the rank order of their potency for inhibition of lung [3H]leukotriene D4 or [3H]leukotriene C4 binding was leukotriene C4 = leukotriene D4 > leukotriene E4. Presence of the complex altered the potency order for both competition studies: for the [3H]leukotriene D4 competition it was leukotriene D4 > leukotriene E4 = leukotriene C4 and for the [3H]leukotriene C4 competition it was leukotriene C4 ≫ leukotriene D4 ≥ leukotriene E4.
