The proposed project is aimed at enhancing the efficiency of epithelial ovarian cancer treatment and reducing adverse side effects chemotherapy using nanotechnology. Overexpression CD44 membrane receptor results in tumor initiation, growth, stem cells' specific behavior, development drug resistance, metastases. We hypothesize that a developed cancer-targeted delivery system combines siRNA with paclitaxel would successfully deliver its payload inside cells, effectively induce cell death,...
Owing to the outstanding near-infrared (NIR) optical properties, phthalocyanines (Pc) have promising potential as theranostic agents for fluorescence image-guided drug delivery and noninvasive treatment of deep tumors by photodynamic therapy (PDT). Nevertheless, clinical application is substantially limited poor water solubility, aggregation insufficient selectivity cancer cells. To address these issues, we developed a novel dendrimer-based platform tumor-targeted phthalocyanines. The...
A single agent-based theranostic nanoplatform was developed for concurrent NIR fluorescence imaging and combinatorial phototherapy with dual photodynamic (PDT) photothermal (PTT) therapeutic mechanisms.
Gestational choriocarcinoma (CC) is a rare and highly malignant cancer originating from the trophoblastic layers of placenta. Currently, methotrexate (MTX) first‐line treatment for CC; however, due to aggressive metastatic nature CC, multiple doses are often required, leading severe side effects lack tumor specificity. The first targeted MTX‐loaded polymersomes (Ps) designed efficient drug delivery CC tumors introduced. modification these Ps nanoplatforms with guanosine (Gn), which targets...
Cryptophane-A, comprised of two cyclotriguaiacylenes joined by three ethylene linkers, is a prototypal organic host molecule that binds reversibly to neutral small molecules via London forces. Of note are trifunctionalized, water-soluble cryptophane-A derivatives, which exhibit exceptional affinity for xenon in aqueous solution. In this paper, we report high-resolution X-ray structures and trifunctionalized derivatives crown–crown crown–saddle conformations, as well complexes with water,...
Fluorescence image-guided surgery combined with intraoperative therapeutic modalities has great potential for detection of oncologic targets and eradication unresectable cancer residues. Therefore, we have developed an activatable theranostic nanoplatform that can be used concurrently two purposes: (1) tumor delineation real-time near infrared (NIR) fluorescence signal during surgery, (2) targeted treatment to further eliminate unresected disease sites by non-toxic phototherapy. Methods: The...
Image-guided phototherapy is extensively considered as a promising therapy for cancer treatment. To enhance translational potential of this modality, we developed single agent-based biocompatible nanoplatform that provides both real time near-infrared (NIR) fluorescence imaging and combinatorial with dual photothermal photodynamic therapeutic mechanisms. The theranostic consists two building blocks: (1) silicon naphthalocyanine (SiNc) NIR phototherapeutic agent (2) copolymer, poly(ethylene...
Abstract Endometriosis is a painful disorder where endometrium‐like tissue forms lesions outside of the uterine cavity. Intraoperative identification and removal these are difficult. This study presents nanoplatform that concurrently delineates ablates endometriosis tissues using real‐time near‐infrared (NIR) fluorescence photothermal therapy (PTT). The consists dye, silicon naphthalocyanine (SiNc), capable both NIR imaging PTT, polymeric nanoparticle as SiNc carrier to following systemic...
Abstract Endometriosis is a devastating disease in which endometrial‐like tissue forms lesions outside the uterus. It causes infertility and severe pelvic pain ≈176 million women worldwide, there currently no cure for this disease. Magnetic hyperthermia could potentially eliminate widespread endometriotic but has not previously been considered treatment because conventional magnetic nanoparticles have relatively low heating efficiency can only provide ablation temperatures (>46 °C)...
mRNA therapeutics encapsulated in lipid nanoparticles (LNPs) offer promising avenues for treating various diseases. While vaccines anticipate immunogenicity, the associated reactogenicity of mRNA-loaded LNPs poses significant challenges, especially protein replacement therapies requiring multiple administrations, leading to adverse effects and suboptimal therapeutic outcomes. Historically, research has primarily focused on cargo, leaving role understudied this context. Adjuvanticity...
We have synthesized and characterized a library of near-infrared (NIR) heptamethine cyanine dyes for biomedical application as photoacoustic imaging photothermal agents.

Among those analyzed, 13 compounds within nontoxic polymeric nanoparticles been selected exemplify structural relationships in terms photostability, imaging,...
Recently, we identified 1-aminoanthracene as a fluorescent general anesthetic. To investigate the mechanism of action, photoactive analogue, 1-azidoanthracene, was synthesized. Administration 1-azidoanthracene to albino stage 40-47 tadpoles found immobilize animals upon near-UV irradiation forebrain region. The immobilization often reversible, but it characterized by longer duration consistent with covalent attachment ligand functionally important targets. IEF/SDS-PAGE examination irradiated...
