Design and Synthesis of Structure-Simplified Derivatives of Gonytolide for the Promotion of Innate Immune Responses.

Gonytolide A (1), a dimeric chromanone substituted with the γ-lactone, shows promoting activity of innate immune responses. However, biological studies on this compound have been limited by the low amounts of 1 available from natural resources and the difficulty of its synthesis. In this study, we designed and synthesized structure-simplified gonytolide derivatives.

Isolation of a Cyclic Depsipetide, Aspergillicin F, and Synthesis of Aspergillicins with Innate Immune-Modulating Activity.

Innate immunity is the front line of self-defense against microbial infection. After searching for natural compounds that regulate innate immunity using an ex vivo Drosophila culture system, we identified a new cyclic depsipeptide, aspergillicin F, from the fungus Aspergillus sp., as an innate immune suppressor.

Structures of the dimeric and monomeric chromanones, gonytolides A-C, isolated from the fungus Gonytrichum sp. and their promoting activities of innate immune responses.

Innate immunity is the front line of self-defense against microbial infection. After searching for natural substances that regulate innate immunity using an ex vivo Drosophila culture system, we identified a novel dimeric chromanone, gonytolide A, as an innate immune promoter from the fungus Gonytrichum sp. along with gonytolides B and C.

[Bacteria isolated from surgical infections and their susceptibilities to antimicrobial agents --special references to bacteria isolated between April 2008 and March 2009].

Bacteria isolated from infections in abdominal surgery during the period from April 2008 to March 2009 were investigated in a multicenter study in Japan, and the following results were obtained. In this series, 712 strains including 18 strains of Candida spp. were isolated from 173 (80.

Chronic outcome of proximal gastrectomy with jejunal pouch interposition in dogs.

Background: To prevent or minimize postgastrectomy complications, proximal gastrectomy with an interposed jejunal pouch has been advocated as an organ-preserving surgical strategy to improve quality of life for the patients. However, the utility of this surgical method has only been evaluated clinically and no reports have been published concerning animal studies. Therefore, we carried out an experiment in beagle dogs to investigate the utility of proximal gastrectomy with an interposed jejunal pouch.
