compounds described as phosphatidylglycerol dimannosides (PGM2). Biological testing of these PIM compounds indicated that the agonist activity was TLR4 dependent. An ether linkage increased agonist activity. Removal of the inositol ring enhanced antagonist activity, and the presence of an additional lipid chain enhanced LPS-induced cytokine production in primary macrophages. Furthermore, the interruption
