Suppression of intestinal Ticam1 ameliorated MASH via Akkermansia muciniphila QAA37749.1 mediated betaine transformation.

Background & Aims: Gut inflammation caused by diets could damage the intestinal barrier, which increases the liver exposition to pathogenic substances. Toll-IL-1 receptor (TIR) domain-containing adaptor molecule-1 (Ticam1) is a key molecule in the Toll-like receptors (TLRs) pathway, which is important for the immune defense against pathogens such as bacteria or viruses. In this study, mouse intestinal epithelial cell (IEC) Ticam1 was knocked out to suppress the intestinal inflammation response in metabolic dysfunction-associated steatohepatitis (MASH) to investigate its influence on the development of MASH.

Metal-Free One-Pot Synthesis of 3-Phosphinoylbenzofurans via Phospha-Michael Addition/Cyclization of H-Phosphine Oxides and in Situ Generated ortho-Quinone Methides.

A novel metal-free one-pot protocol for the effective and efficient synthesis of 3-phosphinoylbenzofurans via a phospha-Michael addition/cyclization of H-phosphine oxides and in situ generated ortho-quinone methides is described. Based on the expeditious construction of C(sp)-P bonds, asymmetric synthesis of optically pure 3-phosphinoylbenzofurans containing chiral P-stereogenic center has also been probed by using chiral R-(-)-menthyl phenylphosphine oxide.
