Inhibition of the NF-κB signaling pathway in tumor cells can effectively reduce inflammation levels, potentially providing antitumor benefits. Resveratrol, a natural polyphenolic compound known for its anti-inflammatory properties, has been shown both anti-inflammatory and anticancer effects in breast cancer cells through the inhibition of NF-κB signaling. Based on the stilbene structure of Resveratrol, we designed and synthesized a series of novel analogs. Preliminary screening indicated that compound 8a exhibited not only anti-inflammatory and antiproliferative effects but also suppressant on the expression of inflammatory factors in MCF-7 breast cancer cells. To gain a deeper understanding of its mechanism of action, we further investigated the inhibitory effect of compound 8a on the NF-κB signaling pathway. The study found that compound 8a can significantly reduce the expression levels of key proteins p65 and IκBα in the classical NF-κB signaling pathway and effectively prevent the entry of p65 protein into the nucleus, thereby exhibiting potent anti-inflammatory effects and potential anti-breast cancer activity. Molecular docking analysis results show that compound 8a interacts with the NF-κB p65 protein through two crucial hydrogen bonds, and this binding affinity is even superior to that of the known Resveratrol. In summary, compound 8a could be a promising drug lead, as a NF-κB inhibitor for breast cancer treatment.</p>","PeriodicalId":708,"journal":{"name":"Molecular Diversity","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144085630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing drug therapies for LF exhibit limited effectiveness across all parasite stages, thereby accentuating the imperative for novel anti-filarial medications characterized by enhanced prognostic attributes and minimized adverse reactions. A promising avenue involves targeting the microbial enzyme WBmDapE, pivotal in worm survival and intricately linked to the lysine biosynthetic pathway and peptidoglycan cell wall construction. This investigation employs in silico methodologies encompassing molecular docking, Molecular Dynamics Simulation (MDS), conformational analysis, Shape-Based Virtual Screening (SBVS), ADMETox, MMGBSA, and Density Functional Theory (DFT) calculations to discern potential inhibitors of WBmDapE. Through discerning the conformational shifts of the WBmDapE-bound substrate and product, key amino acids implicated in substrate binding (Arg182 and Asp248) are unveiled. While the apo and substrate-bound structures exhibit an open conformation, the product-bound structure displays marked conformational alterations, including shifts within the catalytic domain and the cofactor in the dimerization domain, suggestive of an active and closed conformation.
