Pharmaceutical cocrystals have demonstrated favorable and sustainable results in improving the physicochemical and biopharmaceutical characteristics of poorly soluble drugs. To enhance the solubility, dissolution rate, and bioavailability of ACF, we aimed to prepare cocrystals of this biopharmaceutics classification system (BCS) class II drug with a coformer including nicotinamide (NCT), using hot melt extrusion (HME) and liquid-assisted grinding (LAG) methods. ACF-NCT cocrystals synthesized using these methods were characterized using various methods and were further assessed for in vitro anti-osteoporotic and in vivo anti-arthritic activities. The results indicate that both LAG and HME cocrystals demonstrated significant improvement in solubility and dissolution profile compared to pure ACF. However, among these two methods, HME offered more advantages, including better solubility and dissolution profile, than the LAG method. The cocrystals achieved a remarkable 6.15-fold increase in solubility and ⁓3-fold enhancement in dissolution over pure ACF. The relative bioavailability of ACF-NCT HME cocrystal was 249.98% of pure ACF, indicating an improvement in oral bioavailability. The in vivo anti-arthritic activity also demonstrated significant improvement when compared to pure ACF. ACF-nicotinamide cocrystals prepared by hot melt extrusion achieved remarkable gains in solubility, bioavailability, and therapeutic efficacy, providing a promising strategy to overcome ACF's clinical limitations.</p>","PeriodicalId":16741,"journal":{"name":"Journal of pharmaceutical sciences","volume":" ","pages":"104294"},"PeriodicalIF":3.8,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147774710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SMARCA2 PROTACs have been reported with sufficient potency and selectivity to drive in vitro activity, however their rapid clearance from systemic circulation, limited tumor distribution, and dose-limiting toxicity prevented sustained tumor growth inhibition in mouse NSCLC xenograft models. To overcome these issues, we conjugated known SMARCA2 PROTACs to poly-L-lysine dendrimers via hydrolytically cleavable linkers with tunable release rates. We found that the PROTAC release rate from the dendrimer conjugate correlated with the systemic and tumor exposure of the free PROTAC, SMARCA2 degradation in tumor and downstream target modulation, and efficacy in a mouse NSCLC xenograft model. A single dose of an optimized dendrimer-PROTAC conjugate achieved tumor stasis up to 21 days at a significantly lower dose than the PROTAC alone, with no adverse effects.

This study aimed to synthesize ferrous-based metal-organic frameworks (Fe-MOF), a class of hybrid nanomaterials consisting of Fe²⁺ ions and organic ligands, loaded with paclitaxel (PTX) and coated with Bovine Serum Albumin (BSA), to investigate their effects at different doses of X-ray radiation on Human breast epithelial adenocarcinoma (MCF-7) cells. Fe-MOFs were evaluated as a potential drug-releasing nanoparticle, aiming to enhance PTX solubility and promote radiation sensitivity in the MCF-7 breast cancer cell line during radiotherapy. The successful synthesis of Fe-MOF@PTX-BSA and drug loading were confirmed by DLS, TEM, FT-IR, XRD, and BET analyses. Anticancer effects and enhanced radio-sensitivity were validated using MTT, apoptosis, and DAPI assays under irradiated (6MV) and non-irradiated conditions. Fe-MOF@BSA nanoparticles exhibited suitable hemolytic properties at various concentrations. After successfully demonstrating the efficient cellular uptake of nMOFs, in vitro experiments showed that Fe-MOF@PTX-BSA, along with X-ray radiation, activated substantial in situ generation of ROS, leading to increased radio-sensitivity and apoptosis in MCF-7 cells.

To facilitate self-administration of long-acting treatments, we developed a microneedle patch (MNP) for the sustained release of islatravir or levonorgestrel, used for HIV treatment/PrEP or contraception, respectively. The MNPs were produced using a melt-casting technique to quickly create biodegradable polycaprolactone microneedles for continuous drug delivery. The low melting point of polycaprolactone and the high thermal stability of islatravir and levonorgestrel allowed melt casting at 65 °C. Incorporating centrifugation during fabrication improved the attachment of microneedles to the patch backing, making it easier to remove MNPs from the mold and ensuring effective microneedle insertion into skin. The MNPs demonstrated a sustained release of islatravir with roughly first-order release kinetics for ∼40 days in vitro.
