Gossypol inhibited 5- and 12-lipoxygenases of rat basophilic leukemia (RBL-1) cells with ID50 of 0.3 microM and 0.7 microM, respectively. Nearly two orders of magnitude of higher concentration of gossypol was required to inhibit prostaglandin synthetase. The inhibition was of a non-competitive type with respect to arachidonate.
