Cerebroside sulfate (CS) has recently been shown to bind opiate drugs in a pharmacologically relevent manner and therefore satisfy the structural requirements of an opiate receptor. Seminolipid (SGG), a novel sulfated galactosyl. glycerolipid that has been isolated from the testes of a variety of mammals, may be viewed as a structural analog of CS. In view of this structural similarity, it is reasonable to presume that SGG may also bind opiate drugs. The isolation of SGG from boar testes was accomplished using silica gel dry column chromotography with a chloroform: methanol water solvent system. The structure and purity of the isolated SGG were proven by infra-red and thin layer chromotography, respectively. Two methods were used to evaluate the opiate binding potential of SGG compared to that of CS: first, a modified sulfatide analysis using azure-A dye (the Kean test), and second, 3H-opiate binding studies on the brains and testes of rats and mice, and boar testes. Both of these in vitro methods of opiate binding evaluation failed to reveal opiate binding comparable to CS that could be attributed to SGG contained in the testes of rat, mouse and boar.
