Journal ArticleDOI
Synthesis of beta-analogues of C-mannosyltryptophan, a novel C-glycosylamino acid found in proteins.
TL;DR: An efficient synthetic strategy is developed for alpha-C-Man-Trp and its glucose and galactose analogues, starting from alpha- C-glycosidation of the corresponding hexapyranoside derivatives with tinacetylene, and an anomeric mixture of the C-mannosylacetylene is given.
Journal ArticleDOI
First finding of Daidzein 7-O-phosphate and Genistein 7-O-phosphate that are hydrolyzed by sulfatase
Akira Kanakubo,Kazushi Koga,Minoru Isobe,Tatsushi Fushimi,Takanobu Saitoh,Yoshifumi Ohshima,Yoshinori Tsukamoto +6 more
TL;DR: The structural assignment of two water soluble isoflavone analogs of Daidzein and Genistein was initially assumed to be the corresponding sulfates on the basis of the facts that these analogs were hydrolyzed by sulfatase as mentioned in this paper.
Journal ArticleDOI
7,8-Dihydropterin-6-carboxylic acid as light emitter of luminous millipede, Luminodesmus sequoiae
TL;DR: It is concluded that 7,8-dihydropterin-6-carboxylic acid, a new natural product, is the light emitter of Luminodesmus bioluminescence.
Journal ArticleDOI
Isolation of brominated quinones showing chemiluminescence activity from luminous acorn worm, Ptychodera flava.
Akira Kanakubo,Minoru Isobe +1 more
TL;DR: Structural-activity relationship of chemiluminescence activity of halogenated quinone derivatives reveals that a highly halogen substitution and 1,4-quinone skeleton are important for high chemilumscence activity.
Journal ArticleDOI
Differentiation of sulfate and phosphate by H/D exchange mass spectrometry: application to isoflavone.
Akira Kanakubo,Minoru Isobe +1 more
TL;DR: A method to distinguish between phosphate and sulfate by using a popular low-resolution mass instrument is reported, applicable not only to the isoflavone, but also to other phospho and sulfo compounds.
