The 2-(2′-hydroxyphenyl)-4(3H)-quinazolinone (HPQ) scaffold exhibits hydrophobicity, aggregation-induced emission (AIE). The responsive probes built on HPQ can undergo in situ activation and self-assembling precipitation, enabling prolonged retention in lesion sites. Herein, a FAP-cleavable Cbz-Gly-Pro-sequence was conjugated to the phenolic hydroxyl of HPQ via a self-immolative linker, with phenol/tyrosine moieties for 131I labeling through aliphatic linkers, affording LWH-1 and LWH-2. LWH-3 further incorporated a tetraphenylethylene moiety, a PEG6-triazole-PEG6 linker, and (D-Tyr)5-NH2. All precursors for radioiodination responded efficiently to FAP, releasing HPQ-OH to generate AIE and illuminating tumors for over 48 h. [131I]LWH-3 showed a 2.76-fold higher molar activity than [131I]LWH-2 and an in vivo half-life of 43.66 min. In PC12-FAP xenografts, [131I]LWH-3 achieved outstanding antitumor efficacy with favorable biosafety. Transcriptomic and metabolomic analyses revealed that internal radiotherapy attenuated tumor metabolic adaptability by modulating fatty acid metabolism-associated networks to impair proliferation.","PeriodicalId":46,"journal":{"name":"Journal of Medicinal Chemistry","volume":"16 1","pages":""},"PeriodicalIF":7.3,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149210329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we describe the discovery of a novel N-hydroxyindole-2-carboxamide class of PDIA3 inhibitors, exemplified by compound AV22 (1o), which effectively inhibits PDIA3 activity and exerts broad-spectrum antiviral activity against major human respiratory viruses. Mechanistic studies indicated that AV22 (1o) increased the release of non-infectious coronavirus particles and reduced disulfide bond formation in the coronavirus spike protein, indicating that its antiviral effect stems from interference with PDIA3 activity.

Importantly, Fe4/HSA-Fe4 NPs significantly suppressed the metastasis and growth of TNBC in vivo. Moreover, we elucidated the mechanisms by which Fe4/HSA-Fe4 NPs inhibited the growth and metastasis of TNBC: inducing Fenton reaction-mediated chemodynamic therapy, inducing ferroptosis, and tri-activating the immune response through the activation of the cGAS-STING pathway, the induction of immunogenic cell death, and the repolarization of M2 macrophages.","PeriodicalId":46,"journal":{"name":"Journal of Medicinal Chemistry","volume":"29 1","pages":""},"PeriodicalIF":7.3,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149152138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We previously identified a hit compound, BTP15, which protected fibroblasts and THP-1 macrophages from Mtb-induced cell death ex vivo by blocking phagosomal escape through inhibition of the mycobacterial histidine kinase MprB.

Notably, BCy5-Br1−BCy5-Br3 nanoparticles with high LD specificity exhibit significant PDT efficacy at submicromolar concentrations and, by inducing oxidative stress and lipid peroxidation (LPO) accumulation, concurrently trigger apoptosis and ferroptosis, effectively suppressing melanoma growth in vivo.
