Calcium overload, a minimally invasive tumor treatment, aims to accumulate an excessive concentration of Ca²⁺ within mitochondria, triggering apoptosis. Copper sulfide (CuS) represents a photothermal mediator for tumor hyperthermia. However, relying solely on thermotherapy often proves insufficient in controlling tumor growth. Curcumin (CUR), an herbal compound with anti-cancer properties, inhibits the efflux of exogenous Ca²⁺ while promoting its excretion from the endoplasmic reticulum into the cytoplasm. To harness these therapeutic modalities, we have developed a nanoplatform that incorporates hollow CuS nanoparticles (NPs) adorned with multiple CaCO₃ particles and internally loaded with CUR. This nanocomposite exhibits high uptake and easy escape from lysosomes, along with the degradation of surrounding CaCO₃, provoking the generation of abundant exogenous Ca²⁺ <em>in situ</em>, ultimately damaging the mitochondria of diseased cells. Impressively, under laser excitation, the CuS NPs demonstrate a photothermal effect that accelerates the degradation of CaCO₃, synergistically enhancing the antitumor effect through photothermal therapy. Additionally, fluorescence imaging reveals the distribution of these nanovehicles <em>in vivo</em>, indicating their effective accumulation at the tumor site. This nanoplatform shows promising outcomes for tumor-targeting and the effective treatment in a murine model of cervical cancer, achieved through cascade enhancement of calcium overload-based dual therapy.</div></div>","PeriodicalId":8539,"journal":{"name":"Asian Journal of Pharmaceutical Sciences","volume":"19 6","pages":"Article 100989"},"PeriodicalIF":10.7,"publicationDate":"2024-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142705971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, some of these agents still encounter off-target toxicities and suboptimal efficacies due to their inferior biopharmaceutical and/or pharmacokinetic properties. Almost all of these molecules exhibit significant inter- and intra-patient variations in plasma concentration-time profiles. Thus, therapeutic drug monitoring, dose adjustments and precision medicine are being contemplated by clinicians. Complex formulations or nanoformulation-based drug delivery systems offer promising approaches to provide drug encapsulation or spatiotemporal control over the release, overcoming the biopharmaceutical and pharmacokinetic limitations and improving the therapeutic outcomes. In this context, the present review comprehensively tabulates and critically analyzes all the relevant properties (T_1/2, solubility, pK_a, therapeutic index, IC₅₀, metabolism etc.) of the approved smTKIs. A detailed appraisal is conducted on the advancements made in complex formulations of smTKIs, with a focus on strategies to enhance their pharmacokinetic profile, tumor targeting ability, and therapeutic efficacy. Various nanocarrier platforms, have been discussed, highlighting their unique features and potential applications in cancer therapy. Nanoformulations have been shown to improve area under the curve and peak plasma concentration, and reduce dosing frequency for several smTKIs in animal models. It is inferred that extensive efforts will be made in developing complex formulations of smTKIs in near future. There, the review concludes with key recommendations for the developing of smTKIs to facilitate early clinical translation.</div></div>","PeriodicalId":8539,"journal":{"name":"Asian Journal of Pharmaceutical Sciences","volume":"19 6","pages":"Article 100980"},"PeriodicalIF":10.7,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142706558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies have demonstrated that metastasis results from the interaction between “seeds” (tumor cells) and “soil” (pre-metastatic niche, PMN). As the first and most abundant immune cells to be recruited to PMN, neutrophils play a key role in the ultimate formation of metastatic foci through mechanisms such as supporting tumor cell growth, promoting angiogenesis, and shaping an immune-suppressive microenvironment. In this study, two distinct types of sialic acid (SA)-modified liposomes were prepared to target and regulate pro-metastatic neutrophils through the <em>l</em>-selectin receptor. One of these liposomes, named ICG@SAL, was used to encapsulate indocyanine green (ICG) and was specifically designed for the early detection of cancer metastasis. The other liposome, referred to as ABE/Cur@SAL, co-loaded abemaciclib (ABE) and curcumin (Cur), with the intention of suppressing the progression of metastatic tumor. Fluorescence imaging results from the mouse spontaneous metastasis model indicated that ICG@SAL demonstrated faster targeting and stronger accumulation in the metastatic organs than unmodified ICG liposomes (ICG@CL). This suggested that ICG@SAL could detect tumor metastasis at an early stage. The therapy with co-loaded liposomes in the mouse experimental lung metastasis model indicated that ABE/Cur@SAL could inhibit regulatory T (Treg) cell proliferation, enhance effector T cell activity and reduce tumorigenic factor release, implying that ABE/Cur@SAL could inhibit tumor metastasis. Overall, our work provided a sensitive and convenient approach to early diagnosis and treatment of tumor metastasis.

These cyanine dyes can be attacked by self-generated reactive oxygen species (ROS) during PDT processes, resulting in structural damage and rapid degradation, which is fatal for phototherapy. To address this issue, a novel non-cyanine dye (IR890) was elaborately designed and synthesized by our team. The maximum absorption wavelength of IR890 was located in the deep NIR region (<em>ca.</em> 890 nm), which was beneficial for further improving tissue penetration depth. Importantly, IR890 exhibited good stability when continuously illuminated by deep NIR light. To improve the hydrophilicity and biocompatibility, the hydrophobic IR890 dye was grafted onto the side chain of hydrophilic polymer (POEGMA-b-PGMA-g-C<img>CH) <em>via</em> click chemistry. Then, the synthesized POEGMA-<em>b</em>-PGMA-<em>g</em>-IR890 amphiphilic polymer was utilized to prepare P-IR890 nano-photosensitizer <em>via</em> self-assembly method.
