Biocatalytic Preparation of Chiral Alcohols with Micro Green Algae: Bio-reduction of Carbonyl Compounds by Chlorogonium Strains as a Novel Biocatalyst

Autor: Kohji Ishihara, S. Oka, Y. Hayashi, Y. Kondo, Y. Kitagawa, K. Shimoda, Masuoka N. Nakajima

Publikováno v: International Journal of Current Microbiology and Applied Sciences. 11:6-12

Chlorogonium strains were screened to examine the potential ability of microgreen algae to act as biocatalysts. Two culture media (National Institute for Environmental Studies (NIES) recommended AF-6 medium and a synthetic AY medium) were tested for

Graphical abstract
Highlights • H2O2 induces hydrolysis-resistant mouse RBCs and hemolysis. • The hydrolysis-resistant cells were drastically increased in acatalasemic mouse RBCs. • The increase is ameliorated by the addition of α-tocophe

Microbial Production of Chiral Hydroxy Esters and Their Analogs: Biocatalytic Reduction of Carbonyl Compounds by Actinobacteria, Agromyces and Gordonia Strains

Autor: Ayaka Shuto, Noriyoshi Masuoka, Kohji Ishihara, Daisuke Uesugi, Chiharu Kuboki, Nobuyoshi Nakajima, Takumu Mishima, Manami Inoue, Natsumi Adachi, Kazuya Okamoto, Hiroki Hamada

Publikováno v: Advances in Enzyme Research. :15-25

We screened 15 Agromyces strains from the Microbacteriaceae family and 16 Gordonia strains from the Gordoniaceae family to investigate their biocatalytic ability to reduce carbonyl compounds. Two Agromyces strains (A. soli NBRC109063 and A. humatus N

Enzymatic Synthesis of α-Tocopherol Derivative Glycoside, Daidzein Glycoside, Daidzein Oligosaccharide, Resveratrol Oligosaccharide, and Curcumin Oligosaccharides and Their Anti-Allergic Activity and Neuroprotective Activity

Autor: Hatsuyuki Hamada, Atsuhito Kuboki, Takafumi Iwaki, Yuya Kiriake, Kohji Ishihara, Hiroki Hamada

Publikováno v: Natural Product Communications. 16:1934578X2110290

Enzymatic glycosylations of an α-tocopherol derivative, daidzein, resveratrol, and curcumin were investigated. The plant polyphenol, resveratrol, was incubated with glucosyltransferase from Phytolacca americana. The resveratrol glycoside obtained wa

Synthesis of Ester-Linked Paclitaxel-Glycoside Conjugate as a Water-Soluble Paclitaxel Derivative—Maltoside Modification of Paclitaxel through Ester-Linker (Ester-Spacer)

Autor: Kei Shimoda, Tadakatsu Mandai, Hiroki Hamada, Atsuhito Kuboki, Kohji Ishihara, Hatsuyuki Hamada, Yuya Kiriake

Publikováno v: Natural Product Communications. 16:1934578X2110387

To synthesize a water-soluble paclitaxel derivative, the anomers of diols of allyl 2,3,4-tri- O-benzyl-6- O-tritylglycoside (maltoside) were prepared, which can be separated by chromatographic procedure. One anomer was converted into α-glycosyloxyac

Resveratrol Oligosaccharides (Gluco-Oligosaccharides) Effectively Inhibit SARS-CoV-2 Infection: Glycoside (Polysaccharide) Approach for Treatment of COVID-19

Autor: Hatsuyuki Hamada, Takafumi Iwaki, Atsuhito Kuboki, Kei Shimoda, Yuya Kiriake, Kohji Ishihara, Hiroki Hamada

Publikováno v: Natural Product Communications. 16:1934578X2110129

To examine the anti-SARS-CoV-2 effects of resveratrol oligosaccharides, human MRC5 lung cells, which had been infected with SARS-CoV-2, were incubated with different concentrations of resveratrol oligosaccharides. These suppressed the cell death indu
