Anti-LGI1 Antibody-Associated Encephalitis Misdiagnosed as Schizophrenia: A Case Report.

Anti-leucine-rich glioma-inactivated 1 (LGI1) antibody-associated encephalitis is a rare but clinically significant form of autoimmune encephalitis, predominantly affecting middle-aged men. Its heterogeneous clinical presentation often leads to misdiagnosis, commonly as other neurological or psychiatric disorders. This report details the case of a 46-year-old male who initially presented with depressive symptoms, personality changes, and visual hallucinations.

Synthesis and biological evaluation of 1-phenyl-tetrahydro-β-carboline-based first dual PRMT5/EGFR inhibitors as potential anticancer agents.

Protein arginine methyltransferase 5 (PRMT5) and epidermal growth factor receptor (EGFR) are both involved in the regulation of various cancer-related processes, and their dysregulation or overexpression has been observed in many types of tumors. In this study, we designed and synthesized a series of 1-phenyl-tetrahydro-β-carboline (THβC) derivatives as the first class of dual PRMT5/EGFR inhibitors. Among the synthesized compounds, 10p showed the most potent dual PRMT5/EGFR inhibitory activity, with IC values of 15.

An Updated Overview of Synthetic α-glucosidase Inhibitors: Chemistry and Bioactivities.

Diabetes mellitus (DM) is a critical global health issue, affecting nearly half a billion people worldwide, with an increasing incidence rate and mortality. Type 2 diabetes is caused by the body's inability to effectively use insulin, and approximately 95% of patients have type 2 diabetes. α-glucosidase has emerged as an important therapeutic target for the treatment of type 2 diabetes.

Discovery of marine phidianidine-based Nrf2 activators and their potential against oxLDL- and HG-induced injury in HUVECs.

One effective strategy for treating atherosclerosis is to inhibit the injury of vascular endothelial cells (VECs) induced by oxidized low-density lipoprotein (oxLDL) and high glucose (HG). This study synthesized and evaluated a series of novel Nrf2 activators derived from the marine natural product phidianidine for their ability to protect human umbilical VECs against oxLDL- and HG-induced injury. The results of in vitro bioassays demonstrated that compound D-36 was the most promising Nrf2 activator, effectively inhibiting the apoptosis of HUVECs induced by oxLDL and HG.

Discovery of tetrahydroisoquinolineindole derivatives as first dual PRMT5 inhibitors/hnRNP E1 upregulators: Design, synthesis and biological evaluation.

Upregulation of tumor suppressor hnRNP E1 has also been considered as an effective antitumor therapy. In this study, a series of tetrahydroisoquinolineindole hybrids were designed and prepared, and compounds 3m and 3s4 were found to be selective inhibitors of PRMT5 and upregulators of hnRNP E1.

Arginine Methyltransferase 5 (PRMT5) Inhibitors with 3-(1H-benzo[d]imidazol- 2-yl)anilines Core Identified by Virtual Screening and Biological Evaluation.

Background: PRMT5 is a major enzyme responsible for the post-translational symmetric demethylation of protein arginine residues, which has been validated as an effective therapeutic target for cancer. Thus, many nucleoside-based PRMT5 inhibitors have been reported in the past year.

Objective: To discover a novel series of non-nucleoside PRMT5 inhibitors through a molecular docking-based virtual screening approach.

Design, synthesis and biological evaluation of marine phidianidine-inspired derivatives against oxidized ldl-induced endothelial injury by activating Nrf2 anti-oxidation pathway.

Inhibition of oxidized low-density lipoprotein (oxLDL)-induced vascular endothelial cell (VEC) injury is one of the effective strategies for treating atherosclerosis. In the present study, a series of novel marine phidianidine-inspired indole-1,2,4-oxadiazoles was designed, synthesized, and evaluated for their effects against oxLDL-induced injury in VECs. Among them, compound D-6, displaying the most effective protective activity, was found to inhibit oxLDL-induced apoptosis and the expression of ICAM-1 and VCAM-1 in VECs.

Discovery of new 2-phenyl-1H-benzo[d]imidazole core-based potent α-glucosidase inhibitors: Synthesis, kinetic study, molecular docking, and in vivo anti-hyperglycemic evaluation.

In the present study, a series of 2-phenyl-1H-benzo[d]imidazole-based α-glucosidase inhibitors were synthesized and evaluated for their in vitro and in vivo anti-diabetic potential. Screening of an in-house library revealed a moderated α-glucosidase inhibitor, 6a with 3-(1H-benzo[d]imidazol-2-yl)aniline core, and then the structural optimization was performed to obtain more efficient derivatives. Most of these derivatives showed increased activity than 6a, and the most promising inhibitors were found to be compounds 15o and 22d with IC values of 2.

Design, synthesis and biological evaluation of novel (E)-2-benzylidene-N-(3-cyano-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)hydrazine-1-carboxamide derivatives as α-glucosidase inhibitors.

In this present study, a series of novel (E)-2-benzylidene-N-(3-cyano-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)hydrazine-1-carboxamide derivatives against α-glucosidase were designed and synthesized, and their biological activities were evaluated in vitro and in vivo. Most of the designed analogues exhibited better inhibitory activity than the marketed acarbose, especially the most potent compound 7 with an IC value of 9.26 ± 1.

Screening of an in-house library revealed a moderated α-glucosidase inhibitors, 5a, and then the following structural optimization was performed to obtain more efficient derivatives.

Virtual Water Trade in the Service Sector: China's Inbound Tourism as a Case Study.

Research on virtual water and the water footprint is mainly focused on agriculture and industry, and less so on the service sector. The trade in products generates virtual water flow, as does the flow of people. The flow of international tourists will inevitably lead to the transfer and exchange of water resources embedded in the virtual form.

Escape or stay? Effects of haze pollution on domestic travel: Comparative analysis of different regions in China.

Haze pollution has significant impacts on tourist perception and behaviour, including a sharp increase in risk perception and a decline in tourism experience quality. However, given the intervention of multiple factors, whether these impacts necessarily have a negative effect on the overall scale of regional tourism remains unknown. Hence, this paper explored the overall effect of haze pollution on domestic travel.

Virtual water trade of agricultural products: A new perspective to explore the Belt and Road.

The Belt and Road is an initiative of cooperation and development that was proposed by China. Moreover, most of the spanning countries faced water shortages and agriculture consumed a lot of water. Virtual water links water, food and trade and is an effective tool to ease water shortages.
