物理化學(xué)性質(zhì)
制備方法
將100ml三甲胺水溶液與600ml過氧化氫溶液相混合,在室溫放置24h后,如果還有胺的氣味,就再加100~200ml的過氧化氫溶液,當(dāng)所有胺均被氧化后,在減壓下蒸發(fā)至干。殘余物用乙醇-乙醚混合物重結(jié)晶。得二水合氧化三甲胺,為長針狀晶體,產(chǎn)率95%。
在油浴中減壓至1.33~1.6kpa并加熱到120℃,慢慢地升溫至150℃,當(dāng)水分被驅(qū)除后,升溫至180℃~200℃,純的無水氧化三甲胺即升華在瓶子較冷的頸部。
另一種脫水法:將45.0g二水合氧化三甲胺溶于300ml熱DMF中,盛于圓底燒瓶中進(jìn)行蒸餾。先在常壓下加熱以蒸去溶劑,直到沸點(diǎn)達(dá)到152~153℃。然后用水泵減壓以除去殘留的溶劑。蒸餾的末了將油浴的溫度慢慢地升至120℃。剩下的無水氧化三甲胺重30g.

ROS/NLRP3 inflammasome
TGF-β/smad2
The size and migration of fibroblasts are increased after Trimethylamine N-oxide (TMAO) treatment compared with non-treated fibroblasts in vitro. Trimethylamine N-oxide increases TGF-β receptor I expression, which promotes the phosphorylation of Smad2 and up-regulates the expression of α-SMA and collagen I. The ubiquitination of TGF-βRI is decreased in neonatal mouse fibroblasts after Trimethylamine N-oxide treatment. Trimethylamine N-oxide also inhibits the expression of smurf2.
Trimethylamine N-oxide is frequently found in the tissues of a variety of marine organisms that protects against the adverse effects of temperature, salinity, high urea and hydrostatic pressure.
Trimethylamine N-oxide (TMAO) contributes to cardiovascular diseases by promoting inflammatory responses. C57BL/6 mice are fed a normal diet, high-choline diet and/or 3-dimethyl-1-butanol (DMB) diet. The levels of Trimethylamine N-oxide and choline are increased in choline-fed mice. Left ventricular hypertrophy, pulmonary congestion, and diastolic dysfunction are markedly exacerbated in heart failure with preserved ejection fraction (HFpEF) mice fed high-choline diets compared with mice fed the control diet. Myocardial fibrosis and inflammation were markedly increased in HFpEF mice fed high-choline diets compared with animals fed the control diet.
