Although the main cause of degeneration of the nigrostriatal dopaminergic (DA) projection in Parkinson's disease (PD) is still controversial, many reports suggest that excessive inflammatory responses mediated by activated microglia can induce neurotoxicity in the nigrostriatal DA system in vivo. Montelukast, which plays an anti-inflammatory role, is used… (More)
Bacterial colonization relies on communication between bacteria via so-called “quorum-sensing molecules”, which include the acyl-homoserine lactone group. Certain acyl-homoserine lactones can modulate mammalian cell function and are thought to contribute to bacterial pathogenicity. Given the role of mast cells in host defense, we investigated the ability of… (More)
Design, synthesis and insight into the structure-activity relationship (SAR) of 1,3-disubstituted indazoles as novel HIF-1 inhibitors are described. In particular, the substituted furan moiety on indazole skeleton as well as its substitution pattern turns out crucial for the high HIF-1 inhibition.
Structural optimization of multiple H-bonding region and structure-activity relationship of diarylalkyl amides/thioamides as novel TRPV1 antagonists are described. In particular, we identified amide 34o and thioamides 35o and 35r, of which antagonistic activities were highly enhanced by an incorporation of cyano or vinyl-substituent to the multiple… (More)
Morphological abnormalities of the dentate gyrus (DG) are an important phenotype in the hippocampus of patients with temporal lobe epilepsy. We recently reported that naringin, a bioflavonoid in grapefruit and citrus fruits, exerts beneficial effects in the kainic acid (KA) mouse model of epilepsy. We found that naringin treatment reduced seizure activities… (More)
