Previous structure-activity relationship studies revealed that C8-aryl derivatives in pyrimido[5,4-<i>b</i>]indole, especially phenyl and 2-naphthyl compounds, are more potent in the activation of TLR4 signaling. Molecular modeling of these compounds indicated that C8-aryl groups are important for the interaction of the TLR4/myeloid differentiation factor-2 (MD-2) complex. Additionally, the modeling suggested that the N5 position in pyrimido[5,4-<i>b</i>]indole could be used as a further modification site to develop various drug conjugates. In this study, we examined whether the N5 position in pyrimido[5,4-<i>b</i>]indole can be used for conjugation without losing potency. Since tetraethylene glycol (TEG) derivatives at the N5 position were predicted to bind to TLR4/MD-2 complex using in silico molecular docking analysis, the compounds with the TEG group at the N5 position were synthesized and evaluated for immunostimulatory activity by human TLR4 reporter cell assay.

Passive approaches such as selective organ targeting (SORT) lipids show potential but require time-intensive optimization. Active targeting, exemplified by antibody-drug conjugates (ADCs), offers a modular and effective alternative. Building on this, we developed antibody-functionalized hybrid lipid-polymer nanoparticles for siRNA delivery, targeting cancer-overexpressed receptors such as EGFR and TROP2, prevalent in aggressive cancers like triple-negative breast cancer (TNBC). In addition, to enhance therapeutic safety and efficacy, we integrated multi-siRNA delivery into a multicheckpoint targeting strategy, minimizing reliance on single antigens and reducing off-target risks. Using TNBC cells as a model, this platform demonstrates potential for developing a robust and safe therapeutic approach.

Although the first PDT received FDA approval in 1995, clinical adoption has been limited, in part due to the limited tumor selectivity of PSs. The goal of this study was to develop a PS with improved tumor selectivity by incorporating a targeting peptide that selectively binds to the integrin α<sub>v</sub>β<sub>6</sub>. The integrin α<sub>v</sub>β<sub>6</sub> is an epithelial-specific cell-surface receptor that is overexpressed in several cancer types, with expression level often linked to poor overall survival. The integrin α<sub>v</sub>β<sub>6</sub> targeting peptide (ABM-5G) was conjugated onto a water-soluble PS (IRDye700DX, IR700) in solution phase, and the resulting PS-α<sub>v</sub>β<sub>6</sub>-targeted-peptide conjugate (IR700-ABM-5G, <b>1</b>) demonstrated excellent photochemical and photophysical properties, including high extinction coefficient and singlet oxygen productivity similar to the nontargeted PS (free IR700). <i>In vitro,</i> <b>1</b> showed α<sub>v</sub>β<sub>6</sub>-selective binding to and internalization into DX3puroβ6 (α<sub>v</sub>β<sub>6</sub>+) cells vs DX3puro (α<sub>v</sub>β<sub>6</sub>-) cells, and α<sub>v</sub>β<sub>6</sub>-selective phototoxicity with EC<sub>50</sub>s of 1.6 nM for DX3puroβ6 cells and ≥ 250 nM for DX3puro cells. In mice bearing paired DX3puroβ6 (α<sub>v</sub>β<sub>6</sub>+) and DX3puro (α<sub>v</sub>β<sub>6</sub>-) tumor xenografts, the fluorescence intensity of <b>1</b> in DX3puroβ6 (α<sub>v</sub>β<sub>6</sub>+) tumors was 2.5- to 7-fold higher than that of the other tissues (including DX3puro (α<sub>v</sub>β<sub>6</sub>-) tumors, <i>p</i> < 0.0001), except for the kidneys and stomach. A single treatment of <b>1</b> (1.4 nmol per mouse) combined with near-infrared light exposure significantly suppressed the growth of DX3puroβ6 (α<sub>v</sub>β<sub>6</sub>+) tumors (198 ± 112 mm<sup>3</sup> vs 714 ± 251 mm<sup>3</sup> for saline control, <i>p</i> < 0.0001, on day 37 post treatment). In summary, PDT treatment with <b>1</b> demonstrated α<sub>v</sub>β<sub>6</sub>-selective therapeutic efficacy both <i>in vitro</i> and <i>in vivo</i> and is a promising targeted therapy for the treatment of a range of α<sub>v</sub>β<sub>6</sub>-expressing cancers.</p>","PeriodicalId":29,"journal":{"name":"Bioconjugate Chemistry","volume":" ","pages":"1516-1526"},"PeriodicalIF":4.0,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12272554/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144281678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
