  Synthesis and innate immunosuppressive effect of 1,2-cyclopentanediol derivatives

  摘要：

  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.

• Highly Substituted Cyclopentane–CMP Conjugates as Potent Sialyltransferase Inhibitors

  Sialylconjugates on cell surfaces are involved in many biological events such as cellular recognition, signal transduction, and immune response. It has been reported that aberrant sialylation at the nonreducing end of glycoconjugates and overexpression of sialyltransferases (STs) in cells are correlated with the malignance, invasion, and metastasis of tumors. Therefore, inhibitors of STs would provide valuable leads for the discovery of antitumor drugs. On the basis of the transition state of the enzyme-catalyzed sialylation reaction, we proposed that the cydopentane skeleton in its two puckered conformations might mimic the planar structure of the donor (CMP-Neu5Ac) in the transition state. A series of cydopentane-containing compounds were designed and synthesized by coupling different cydopentane alpha-hydroxyphosphonates with cytidine phosphoramidite. Their inhibitory activities against recombinant human ST6Gal-I were assayed, and a potent inhibitor 481 with a K-i of 0.028 +/- 0.006 mu M was identified. The results show that the cydopentanoid-type compounds could become a new type of sialyltransferase inhibitors as biological probes or drug leads.
