Salvianolic acid B-loaded polydopamine-modified hollow mesoporous organic silica nanoparticles for treatment of breast cancer metastasis via suppressing cancer-associated fibroblasts
CONCLUSION: We successfully prepared SAB@HMON-PDA with the dual response of pH and GSH. SAB@HMON-PDA can inhibit the migration and invasion of 4T1 cells, and the effect is more significant than free SAB. This inhibitory effect may be related to the inhibition of CAFs. In vivo experiments demonstrated that SAB@HMON-PDA can inhibit lung metastasis of breast cancer by inhibiting CAFs, and its effect was more significant than that of free SAB.PMID:37972905 | DOI:10.1016/j.ejps.2023.106641 (Source: European Journal of Pharmaceutical Sciences)

Altering distribution profile of palbociclib by its prodrugs
Eur J Pharm Sci. 2023 Nov 13:106637. doi: 10.1016/j.ejps.2023.106637. Online ahead of print.ABSTRACTPalbociclib, a cyclin-dependent kinase (CDK) 4/6 inhibitor, is currently used clinically for treating hormone receptor-positive and human epidermal growth factor receptor 2 negative breast cancer. Additionally, it has the potential to be utilized in the treatment of various tumors, including malignant glioblastoma. Previous research has indicated that palbociclib is a substrate for two efflux transporters, P-glycoprotein (P-gp; MDR1) and breast cancer-resistant protein (BCRP), which restrict the brain exposure of palbociclib...

Nanostructured lipid carriers loaded into in situ gels for breast cancer local treatment
In conclusion, these results contribute to improving our understanding of nanocarrier design with increased cytotoxicity and prolonged retention for the intraductal route. Tributyrin incorporation increased the cytotoxicity of paclitaxel and 5-fluorouracil in monolayer and spheroids, while NLC incorporation in thermosensitive gels prolonged tissue retention of both hydrophilic and hydrophobic compounds.PMID:37967657 | DOI:10.1016/j.ejps.2023.106638 (Source: European Journal of Pharmaceutical Sciences)

Analysis of Stabilization Mechanisms in β-Lactoglobulin-based Amorphous Solid Dispersions by Experimental and Computational Approaches
Eur J Pharm Sci. 2023 Nov 13:106639. doi: 10.1016/j.ejps.2023.106639. Online ahead of print.ABSTRACTOur previous work shows that β-lactoglobulin-stabilized amorphous solid dispersion (ASD) loaded with 70% indomethacin remains stable for more than 12 months. The stability is probably due to hydrogen bond networks spread throughout the ASD, facilitated by the indomethacin which has both hydrogen donors and acceptors. To investigate the stabilization mechanisms further, here we tested five other drug molecules, including two without any hydrogen bond donors. A combination of experimental techniques (differential scanning cal...

Topical delivery of seriniquinone for treatment of skin cancer and fungal infections is enabled by a liquid crystalline lamellar phase
Eur J Pharm Sci. 2023 Nov 10:106635. doi: 10.1016/j.ejps.2023.106635. Online ahead of print.ABSTRACTSeriniquinone (SQ) was initially described by our group as an antimelanoma drug candidate and now also as an antifungal drug candidate. Despite its promising in vitro effects, SQ translation has been hindered by poor water-solubility. In this paper, we described the challenging nanoformulation process of SQ, which culminated in the selection of a phosphatidylcholine-based lamellar phase (PLP1). Liposomes and nanostructured lipid carriers were also evaluated but failed to encapsulate the compound. SQ-loaded PLP1 (PLP1-SQ) was...

Digestion is a critical element for absorption of cinnarizine from supersaturated lipid-based type I formulations
Eur J Pharm Sci. 2023 Nov 9:106634. doi: 10.1016/j.ejps.2023.106634. Online ahead of print.ABSTRACTEnabling formulations, such as lipid-based formulations (LBFs), are means to deliver challenging-to-formulate, poorly soluble drugs. LBFs may be composed of lipids, surfactants and/or cosolvents and can be classified depending on the proportions of the components and the hydrophilicity of the surfactant according to the Lipid Formulations Classification System, ranging from type I (very lipophilic) to type IV (hydrophilic). In cases where drug solubility in LBFs does not suffice, e.g. for preclinical toxicity studies, supersa...

Preparation of Polycaprolactone and Polymethacrylate Nanofibers for Controlled Ocular Delivery of Ketorolac tromethamine: Pharmacokinetic study in Rabbit's Eye
Eur J Pharm Sci. 2023 Nov 9:106631. doi: 10.1016/j.ejps.2023.106631. Online ahead of print.ABSTRACTOphthalmitis is an inflammation of the eye triggered by various conditions including diseases, allergy, trauma, or surgery. Management of this condition usually includes administration of topical anti-inflammatory eye drops such as nonsteroidal anti-inflammatory drugs. To overcome the challenges of conventional eye drops such as frequent administration and low intraocular bioavailability, nanofibrous inserts of Ketorolac tromethamine (KET) were developed in this study. Polycaprolactone and polymethacrylate containing KET were...

A robust analytical method for simultaneous quantification of 13 low-molecular-weight N-Nitrosamines in various pharmaceuticals based on solid phase extraction and liquid chromatography coupled to high-resolution mass spectrometry
Eur J Pharm Sci. 2023 Nov 9:106633. doi: 10.1016/j.ejps.2023.106633. Online ahead of print.ABSTRACTRecently, the potentially highly carcinogenic N-nitrosamines (NAs) have become the focus of pharmaceutical regulatory authorities, the pharmaceutical industry and researchers because trace amounts have been detected in some drug products (DPs), resulting in drug supply shortages. In the absence of sufficient analytical methods for the determination of multiple regulated low-molecular-weight NAs in various DPs, a robust, selective, sensitive and accurate method based on sample preparation by solid-phase extraction, followed by...
