Inhibition of cellular and animal inflammatory disease models by nf-κb inhibitor dhmeq

General inflammatory diseases include skin inflammation, rheumatoid arthritis, inflammatory bowel diseases, sepsis, arteriosclerosis, and asthma. Although these diseases have been extensively studied, most of them are still difficult to treat. Meanwhile, NF-κB is a transcription factor promoting the expression of many inflammatory mediators. NF-κB is likely to be involved in the mechanism of most inflammatory diseases. We discovered a specific NF-κB inhibitor, dehydroxymethylepoxyquinomicin (DHMEQ), about 20 years ago by molecular design from a natural product. It directly binds to and inactivates NF-κB components. It has been widely used to suppress cellular and animal inflammatory disease models and was shown to be potent in vivo anti-inflammatory activity without any toxicity. We have prepared ointment of DHMEQ for the treatment of severe skin inflammation. It inhibited inflammatory cytokine expressions and lowered the clinical score in mouse models of atopic dermatitis. Intraperitoneal (IP) administration of DHMEQ ameliorated various disease models of inflammation, such as rheumatoid arthritis, sepsis, and also graft rejection. It has been suggested that inflammatory cells in the peritoneal cavity would be important for most peripheral inflammation. In the present review, we describe the synthesis, mechanism of action, and cellular and in vivo anti-inflammatory activities and discuss the clinical use of DHMEQ for inflammatory diseases.

Syntheses of Englerin A, a Potent Renal Cancer Inhibitor

Hagihara S., Hanaya K., Sugai T., Shoji M.

Asian Journal of Organic Chemistry （Asian Journal of Organic Chemistry） 8 （ 1 ） 48 - 62 2019年01月

ISSN 21935807

© 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim Mankind has been searching for anticancer drugs from nature and artificial compounds. Since the discovery of englerin A, a guaiane sesquiterpene possessing the characteristic tricyclic 5–6-5 fused ring framework with contiguous seven stereogenic centers and isolated from Phyllanthus engleri, many synthetic groups have enthusiastically launched and accomplished its the chemical synthesis. All the synthetic groups focused on how to efficiently construct the tricyclic framework containing oxygen bridge with various approaches. In this review, the total and formal syntheses of englerin A reported to date are summarized.

Recent examples of the use of biocatalysts with high accessibility and availability in natural product synthesis (Tetrahedron Report No. 1164)

Sugai T., Higashibayashi S., Hanaya K.

Tetrahedron （Tetrahedron） 74 （ 27 ） 3469 - 3487 2018年07月

ISSN 00404020

© 2018 Elsevier Ltd Utilization of biocatalysts with high accessibility and availability, which have recently been applied in the preparation of enantiomerically enriched starting materials and synthetic intermediates for natural product syntheses (mainly 2013–2017) are summarized in this review. The main contents are as follows: 1) recruitment of biocatalysts for the transformation of organic compounds; 2) special precautions for preparative-scale biocatalytic synthetic experiments; 3) asymmetric reduction of carbonyl substrates; 4) kinetic resolution of alcohol and carboxylate enantiomers; 5) desymmetrization of multifunctional alcohol and carboxylate substrates; and 6) recognition of remote and non-central chirality.
