Bis (dipalmitoyl D, L-α-glycerylphosphoryl)-1, 3-glycerol disodium salt (I) was synthesized by the condensation of the silver salt of dipalmitoyl D, L-α-glycerophosphoric acid benzyl ester (XI) with 1, 3-diiodopropanol benzyl ether, followed by debenzylation with sodium iodide and hydrogenolysis with palladium black. Bis (dipalmitoyl D, L-α-glycerylphosphoryl)-1, 5-pentanediol disodium salt (III), bis (dipalmitoyl D, L-α-glycerylphosphoryl)-1, 4-butanediol disodium salt (IV), bis (dipalmitoyl D, L-α-glycerylphosphoryl)-1, 2-ethanediol disodium salt (VI) and bis (dipalmitoyl D, L-α-glycerylphosphoryl) methanediol disodium salt (VII) were synthesized similarly by the condensation of the silver salt (XI) with alkyl diiodide or dibromide, followed by debenzylation with sodium iodide. Bis (benzylphosphoryl)-1, 3-propanediol disodium (X) was synthesized by condensation of silver dibenzyl phosphate with alkyl diiodide, followed by debenzylation with sodium iodide.

The method includes the steps of performing in-vitro liver, intestinal and/or expressed enzyme assays with selected ethnobotanical substances, for both humans and a variety of animal species, to produce an array of resulting chemical entities, such as metabolites, for the human and the animals. Comparisons are then made between the chemical entities from the human in-vitro studies and the animal in-vitro studies to determine the closest match. The animal with the closest match is then used for an in-vivo study. If a match is present between the animal in-vivo results and the human in-vitro results, the matched chemical entity is isolated or synthesized and then further tested to determine the suitability of the matched chemical entity as a treatment drug.

been isolated from a marine sponge Monanchora sp. as antibacterial constituents. Their structures including relativestereochemistry were determined by interpretation of spectral data. The absolutestereochemistry of merobatzelladine B (2) was elucidated after introduction of the fourth ring system preinstalled with a secondary hydroxyl group to which the modifiedMoshermethod was applied.
