Innate immunity is the front line of self-defense against infectious microorganisms. In mammals, innate immunity interacts with adaptive immunity and plays a key role in regulating the immune response. Therefore, innate immunity is a good pharmaceutical target for the development of immune regulators. After searching for natural substances that regulate innate immunity using an ex vivo Drosophila culture system, we identified a cyclopentanediol-type compound 1 as an immunosuppressor. In this study, we synthesized and evaluated 1 and its derivatives. Several methylamide- or phenylamide-containing derivatives showed effects that were 20-25 times more potent than those of 1.
