DAAS is the diacetoxy acetal derivative of a-santonin and induces HL-60 cell differentiation into granulocytes. In this report, we investigated the structure-activity relationship (SAR) of DAAS derivatives in the differentiation of human HL-60 leukemia cells. Although its derivatives themselves had

Soon after its foundation in 1919, Nippon Shinyaku Co., Ltd began to develop the domestic production of Santonin, an anthelmintic agent, which, until then, had been totally imported from Russia. In 1927, Artemisia maritima ssp. monogyna was introduced from Europe
Cell suspension cultures of five plants (Catharanthus roseus, Ginkgo biloba, Platycodon grandiflorum, Taxus cuspidata, Phytolacca asinosa) were employed to bioconvert the eudesmanolide compound, alpha-santonin. Reactions occurring were hydroxylation (C-1, C-11 and C-15), reduction of the double bond [1(2) or 3(4)]

Recently, we developed a concept known as biology-oriented synthesis (BIOS), which targets the design and synthesis of small- to medium-sized compound libraries on the basis of genuine natural product templates to provide screening compounds with high biological relevance. We herein
The fungus, Absidia coerulea was employed to bioconvert tetrahydro-alpha-santonins, 1,2,4alpha,5alpha-tetrahydro-alpha-santonin (1), and its 4-epimer (2), from which 10 products (3-12) were obtained. Furthermore, their structures were determined, based on their chemical and spectroscopic data analyses. Among them, 3-5, 7, 9
