N-site-selective cross-couplings of tetrazoles with indoles.

A method for the site-selective cross-coupling of the N-position of tetrazoles with indoles is reported. The -generated N-iodotetrazole intermediates are found to be critical for both activating indoles and achieving N-selectivity. Upon reaction with indoles, heterolytic cleavage of the N-I bond in N-iodotetrazoles predominantly generates N-localized anions.

N-Alkylation of 1,2,3-Triazoles with Ethers under Thermodynamical Control.

Herein, a relay strategy incorporating oxidative cross dehydrogenative coupling (CDC) and N- to N-isomerization is disclosed for the formal N-selective alkylation of triazoles with ethers under thermodynamic control conditions. By taking advantage of the different thermodynamical stabilities of N- and N-alkylated triazoles (3.65 kcal/mol), the initially formed N-isomers can be converted into their more stable N-isomers when reaching thermodynamic equilibrium.

SSRI antidepressant citalopram reverses the Warburg effect to inhibit hepatocellular carcinoma by directly targeting GLUT1.

Selective serotonin reuptake inhibitors (SSRIs) have shown promise in cancer therapy, particularly for hepatocellular carcinoma (HCC), but their molecular targets and mechanisms remain unclear. Here, we show that SSRIs exhibit significant anti-HCC effects independent of their classical target, the serotonin reuptake transporter (SERT). Using global inverse gene expression profiling, drug affinity responsive target stability assays, and in silico molecular docking, we demonstrate that citalopram targets glucose transporter 1 (GLUT1), resulting in reduced glycolytic flux.

Impaired implicit emotion regulation in patients with panic disorder: An event-related potential study on affect labeling.

Background: Panic disorder (PD) involves emotion dysregulation, but its underlying mechanisms remain poorly understood. Previous research suggests that implicit emotion regulation may play a central role in PD-related emotion dysregulation and symptom maintenance. However, there is a lack of studies exploring the neural mechanisms of implicit emotion regulation in PD using neurophysiological indicators.

The PM-AI system and four eye doctors (retinal specialists 1 and 2, and ophthalmologists 1 and 2) independently evaluated the color fundus photographs to determine whether they were indicative of PM or not and the presence of myopic choroidal neovascularization (mCNV).

Synthesis and anti-parasites efficacy of coumarin derivatives against Dactylogyrus intermedius.

Dactylogyrus is one of the most common parasitic diseases in fish and causes huge losses to the aquaculture industry. With the advantages of safety, low toxicity and easy degradation, plant-derived drugs are ideal for the creation of green aquatic ingredients. The use of plant-derived drugs in aquaculture is limited by their low content and high processing costs, which is a challenge that can be solved by the chemical synthesis of plant-derived drugs.

An extracellular matrix-inspired self-healing composite hydrogel for enhanced platelet-rich plasma-mediated chronic diabetic wound treatment.

Diabetes is generally accompanied by difficult-to-heal wounds, which often lead to permanent disability and even death of patients. Because of the abundance of a variety of growth factors, platelet rich plasma (PRP) has been proven to have great clinical potential for diabetic wound treatment. However, how to suppress the explosive release of its active components while realizing adaptability to different wounds remains important for PRP therapy.

Chrysanthemum sporopollenin: A novel vaccine delivery system for nasal mucosal immunity.

Objective: Mucosal immunization was an effective defender against pathogens. Nasal vaccines could activate both systemic and mucosal immunity to trigger protective immune responses. However, due to the weak immunogenicity of nasal vaccines and the lack of appropriate antigen carriers, very few nasal vaccines have been clinically approved for human use, which was a major barrier to the development of nasal vaccines.

Herein, mussel-inspired chemistry has been integrated with two-dimensional HOIPs first, leading to the preparation of new crystal (HDA)PbBr () (DA = dopamine). The organic cation dopamine can be introduced into PDA resulting in a thin film of (HPDA)PbBr ().

Efficacy of femoral periarterial block in preventing thigh tourniquet pain: a randomized controlled trial.

Background: Tourniquet pain, described as a dull, tight, poorly localized aching sensation, is common in conscious patients. Although various pain-reduction methods have been implemented, none are completely effective. Femoral periarterial block (FAB) has been shown to attenuate tourniquet-induced hypertension in patients undergoing general anesthesia.

N-Selective β-Thioalkylation of Benzotriazoles with Alkenes.

Herein, N-selective β-thioalkylation of benzotriazoles with unactivated alkenes and styrenes is reported. The N-selective β-thioalkylation of benzotriazoles is highly stereospecific and works under simple and mild conditions, exhibiting excellent functional group tolerance. The high N-selectivity is a consequence of the combination of hydrogen bonding and Lewis acid/base activation, which reverses the N-position to be favored for alkylation.
