Identification of novel tetrahydroquinoxaline derived phenyl ureas as modulators of the hepatitis B virus nucleocapsid assembly.

A key step of hepatitis B virus (HBV) replication is the selective packaging of pregenomic RNA (pgRNA) by core protein (Cp) dimers, forming a nucleocapsid where the reverse transcriptional viral DNA replication takes place. One approach in the development of new anti-HBV drugs is to disrupt the assembly of HBV nucleocapsids by misdirecting Cp dimers to assemble morphologically normal capsids devoid of pgRNA. In this study, we built upon our previous discovery of benzamide-derived HBV capsid assembly modulators by exploring fused bicyclic scaffolds with an exocyclic amide that is β, γ to the fused ring, and identified 1,2,3,4-tetrahydroquinoxaline derived phenyl ureas as a novel scaffold.

2023 Chinese expert consensus on the impact of COVID-19 on the management of cardiovascular diseases.

Standardization of organoid culture in cancer research.

Establishing a valid in vitro model to represent tumor heterogeneity and biology is critical but challenging. Tumor organoids are self-assembled three-dimensional cell clusters which are of great significance for recapitulating the histopathological, genetic, and phenotypic characteristics of primary tissues. The organoid has emerged as an attractive in vitro platform for tumor biology research and high-throughput drug screening in cancer medicine.

Combined application of dupilumab and mite allergen-specific immunotherapy in children with moderate to severe atopic dermatitis.

Application of XOLAIR® (Omalizumab) in adolescent refractory chest tightness variant asthma.

Background: Asthma can manifest in a variety of clinical phenotypes like cough variant asthma, chest tightness variant asthma (CTVA), and masked asthma. Patients with CTVA usually have a singular or primary complaint of chest tightness, which is often overlooked or misdiagnosed due to the lack of characteristic asthma symptoms. We hereby report a case of CTVA managed by omalizumab.

Evaluation of CD4/CD8 ratio in children with immune thrombocytopenic purpura (ITP) after treatment with intravenous immunoglobulin (IVIG).

Intra Venous Immunoglobulin (IVIG) is a plasma-derived product used to treat many autoimmune diseases, including thrombocytopenia, immunodeficiency, and infectious diseases. In this study, the effect of IVIG injection was evaluated on the number of white blood cells, neutrophils, lymphocytes, and platelets.

Differences and Correlations of Anxiety, Sleep Quality, and Pressure-Pain Threshold between Patients with Chronic Low Back Pain and Asymptomatic People.

Background: Chronic low back pain (CLBP) is a clinically common and expensive disease. Patients frequently take sick leaves because of pain and dysfunction, and their unpleasant life and work experiences cause psychological depression and anxiety and affect their quality of life. Sleep disturbance is a common problem among patients with low back pain (LBP) with more than 50% complaining about poor sleep quality.

A Multicenter Randomized Trial Assessing ZENFlow Carrier-Free Drug-Coated Balloon for the Treatment of Femoropopliteal Artery Lesions.

Backgrounds And Objectives: Drug-coated balloons (DCBs) have shown promising benefits in improving the outcomes for patients with peripheral artery disease. Several randomized clinical trials have reported that paclitaxel-coated balloon significantly reduce the rates of restenosis and the need for reintervention in comparison with regular balloon angioplasty. Due to the differences in excipients, paclitaxel dose, and coating techniques, variable clinical outcomes have been observed with different DCBs.

Thus, the current study set out to explore the role of NORAD derived from extracellular vesicles (EVs) of bone mesenchymal stem cells (BMSCs) in osteosarcoma.

Anti-hypertensive medications and risk of colorectal cancer: a systematic review and meta-analysis.

Purpose: Antihypertensive medications may impact colorectal cancer risk. We conducted a systematic review and meta-analysis of associations, with colorectal cancer risk, of five classes of antihypertensive medications: angiotensin-converting enzyme inhibitors (ACEIs), angiotensin II receptor blockers (ARBs), beta-blockers (BBs), calcium channel blockers (CCBs), and diuretics.

Methods: A systematic search was conducted in MEDLINE, Embase, Web of Science, and the Cochrane library to identify relevant studies evaluating associations of ACEIs, ARBs, BBs, CCBs, and diuretics with colorectal cancer risk.

Loss of NLRP3 increases bacterial cystitis via IRAKM.

Background: We attempted to characterize the molecular mechanisms that underpin urinary tract infections using a mouse model of cystitis induced by bacterial infection in a background of NOD-, LRR- and PYD domains-containing protein (NLRP3) deficiency.

Methods: Male NLRP3 knockout (NLRP3) and control mice (12 weeks old) were intraurethrally inoculated with 2×10 () and euthanized 1, 3, and 7 days later to assess the degree of bladder infection. Immunohistochemical detection of NLRP3 and interleukin-1 receptor-associated kinase M (IRAKM) was performed.

4-Oxooctahydroquinoline-1(2H)-carboxamides as hepatitis B virus (HBV) capsid core protein assembly modulators.

Hepatitis B virus (HBV) core protein, the building block of the HBV capsid, plays multiple roles in viral replication, and is an attractive target for development of antiviral agents with a new mechanism of action. In addition to the heteroaryldihydropyrimidines (HAPs), sulfamoylbenzamides (SBAs), dibenzothiazepine derivatives (DBTs), and sulfamoylpyrrolamides (SPAs) that inhibit HBV replication by modulation of viral capsid assembly and are currently under clinical trials for the treatment of chronic hepatitis B (CHB), other chemical structures with activity to modulate HBV capsid assembly have also been explored. Here we describe our continued optimization of a benzamide originating from our high throughput screening.
