Article Abstract
The neurokinin-3 receptor (NK3R) has emerged as a promising therapeutic target. Recent evidence indicates that oral administration of an NK3R antagonist to block neurokinin B signaling significantly alleviates hot flash symptoms. Despite this potential, only one NK3R ligand (ESN-364) has been clinically approved to date. To address this gap, we developed a series of imidazole-piperazine derivatives (-, -, and -) through rational design and synthesis. Molecular docking validated the structural rationale, with compound demonstrating superior target binding potency and robust NK3R inhibitory activity. Notably, exhibited an enhanced membrane permeability and high oral bioavailability. efficacy studies revealed that oral effectively suppressed luteinizing hormone levels, supporting its potential for further optimization.

Aberrant activation of fibroblast growth factor receptors (FGFRs) plays a critical role in tumorigenesis across multiple cancer types, driving the development of various FGFR inhibitors. Despite clinical advances, therapeutic efficacy remains limited by the emergence of drug resistance, primarily mediated by gatekeeper mutations in FGFRs. To overcome this challenge, we designed and synthesized a novel series of 7-(1-methyl-1-indole-3-yl)-5-pyrrolo[2,3-]pyrazine derivatives as covalent pan-FGFR inhibitors targeting both wild-type and gatekeeper mutants.

Per- and polyfluoroalkyl substances (PFASs) are environmentally persistent, bioaccumulative, and toxic chemicals that contaminate global drinking water resources. Their ubiquity and potential impact on human health motivate large-scale remediation. Conventional materials used to remove PFASs during drinking water production are functionally inefficient or energetically expensive, motivating the discovery of new materials and technologies.

Electrogenerated chemiluminescence (ECL) methods have been widely used in clinical diagnosis. Although ECL peptide-based biosensors continue to grow with good sensitivity and signal flexibility, little emphasis has been placed on the effect of the peptide sequence on ECL sensitivity. We herein studied the nuanced effects of different peptide sequences on the analytical performance of ECL peptide-based biosensors for matrix metalloproteinase 2 (MMP-2) assay, in which [(pbz)Ir(DMSO)Cl] (pbz = 3-(2-pyridyl)benzoic acid) was used as the ECL emitter while a specific peptide was used as the molecular recognition element.

Parasitic diseases continue to be a major public health burden, particularly in low- and middle-income countries. With the emergence of drug-resistant strains and limitations of current therapies, there is a growing interest in natural products as alternative treatment options. Coumarins, a diverse class of plant-derived secondary metabolites, have shown significant potential as antiparasitic agents.

Pd-zeolites are promising passive NO adsorber (PNA) materials for mitigating cold-start emissions from lean-burn engines. However, their practical deployment is constrained by insufficient densities and dispersion of isolated Pd active sites as well as their susceptibility to hydrothermal degradation and phosphorus poisoning encountered in vehicle exhaust environments. Herein, we develop a rationally engineered core-shell Pd/SSZ-13@AlO composite, featuring a Pd/SSZ-13 core encapsulated within a mesoporous AlO shell.
