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

BMEMat, 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

Nippon 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 ...

Promiscuous Ability of Human Carbonic Anhydrase: QM and QM/MM Investigation of Carbon Dioxide and Carbodiimide Hydration

, 2016
The hydration of carbodiimide, isoelectronic with carbon dioxide, mediated by human carbonic anhydrase (EC 4.2.1.1) was studied at theoretical level in comparison with the native substrate. Quantum-mechanical (QM) and combined quantum-mechanics/molecular-

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

Chemistry – 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 ...

Harnessing Random Polymers as Chemoselective Catalysts With Structural Adaptability: Epoxidation of Olefinic Quaternary Ammonium Salts via Charge Recognition

Chemistry – A European Journal, EarlyView.
The development of chemoselective catalysts that operate across structurally diverse substrates remains a long‐standing challenge. Here, we demonstrate that a random heteropolymer bearing carboxylic acid and urea residues functions as a general epoxidation catalyst for olefinic quaternary ammonium salts.
