Deciphering the catalytic and pharmacological mechanisms of Coptis chinensis herbzymes to renovate intestinal microenvironment for colitis alleviation

open access: yesBMEMat, EarlyView.
The synthesized CCzymes possess both antioxidant enzyme activity and pharmacological properties inherent to Coptis chinensis. By their antioxidant enzyme activity, CCzymes can attenuate oxidative stress within the inflammatory region of ulcerative colitis (UC), while their pharmacological activity acts on macrophage polarization and the intestinal ...

A Novel Method for the Synthesis of Carbodiimide

open access: yesNippon kagaku zassi, 1971
N, N'-ニ置換チオ尿素と2, 3-ジクロル-5, 6-ジシアン-p-ベンゾキノン(DDQ)およびp-ベンゾキノンとの反応について研究を行なった。無水ニ塩化メチレン中,室温でN, N'-ニ置換チオ尿素とDDQとの反応を行なって黄色の生成物〔A〕を得た。この生成物〔A〕を過剰の2N水酸化ナトリウムで処理すると,対応するN, N'-ニ置換カルボジイミドを約70%の収率で与え,同時に2, 3-ジクロル-5, 6-ジシアンヒドロキノンおよび遊離イオウが得られた。一方, N, N'-ニ置換チオ尿素とp-ベンゾキノンとの反応を上記の条件で試みたが24時間後も反応は認められなかった。しかし2N塩酸の存在ではただちに反応が起こり油状または結晶性物質〔B〕が得られた。生成物〔B ...

Sydnone photochemistry: Direct observation of earl's bicyclic lactone valence isomers (oxadiazabicyclo[2.1.0] pentanones), formation of carbodiimides, reaction mechanism, and photochromism

open access: yes, 2014
The matrix photolyses of 3-phenyl-, 3-pyridyl, and 3,4-diphenylsydnones 16, 19, and 22 were investigated by matrixisolation infrared spectroscopy. The formation of the neutral, bicyclic lactone valence isomers postulated by Earl - the oxadiazabicyclo[2.1.

Synthesis and Isolation of Bismuth Scorpionate Complexes: Toward Bond Activation via Bismuth‐Ligand Cooperation

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Over the past twenty years, main group chemistry has significantly expanded its scope to include reactivities once considered the exclusive domain of transition metals. Among the emerging concepts, element‐ligand cooperation has proven to be a powerful strategy for enabling bond activation reactions but remains relatively unexplored for ...
