投稿须知/期刊简介:
The International Journal of Pharmaceutics provides a medium for the publication of innovative papers, reviews, mini-reviews, short communications and notes dealing with physical, chemical, biological, microbiological and engineering studies related to the conception, design, production, characterisation and evaluation of drug delivery systems in vitro and in vivo. "Drug" is defined as any therapeutic or diagnostic entity, including oligonucleotides, gene constructs and radiopharmaceuticals. Areas of particular interest include: physical pharmacy; polymer chemistry and physical chemistry as applied to pharmaceutics; excipient function and characterisation; biopharmaceutics; absorption mechanisms; membrane function and transport; novel routes and modes of delivery; responsive delivery systems, feedback and control mechanisms including biosensors; applications of cell and molecular biology to drug delivery; prodrug design; bioadhesion (carrier-ligand interactions); and biotechnology (protein and peptide delivery). Editorial Policy The over-riding criteria for publication are originality, high scientific quality and interest to a multidisciplinary audience. Papers not sufficiently substantiated by experimental detail will not be published. Any technical queries will be referred back to the author, although the Editors reserve the right to make alterations in the text without altering the technical content. Manuscripts submitted under multiple authorship are reviewed on the assumption that all listed authors concur with the submission and that a copy of the final manuscript has been approved by all authors and tacitly or explicitly by the responsible authorities in the laboratories where the work was carried out. If accepted, the manuscript shall not be published elsewhere in the same form, in either the same or another language, without the consent of the Editors and Publisher. Authors must state in a covering letter when submitting papers for publication the novelty embodied in their work or in the approach taken in their research. Routine bioequivalence studies are unlikely to find favour. No paper will be published which does not disclose fully the nature of the formulation used or details of materials which are key to the performance of a product, drug or excipient. Work which is predictable in outcome, for example the inclusion of another drug in a cyclodextrin to yield enhanced dissolution, will not be published unless it provides new insight into fundamental principles.

A novel injectable nanotherapeutic platform increasing the bioavailability and anti-tumor efficacy of Arachidonylcyclopropylamide on an ectopic non-small cell lung cancer xenograft model: A randomized controlled trial.
Rapid progressing non-small cell lung adenocarcinoma (NSCLC) decreases treatment success. Cannabinoids emerge as drug candidates for NSCLC due to their anti-tumoral capabilities. We previously reported the controlled release of Arachidonylcyclopropylamide (ACPA) selectively targeting cannabinoid 1 (CB1) receptor in NSCLC cells in vitro. Hydrophobic polymers like polycaprolactone (PCL) offer prolonged circulation time and slower drug clearance which is suitable for hydrophobic molecules like ACPA. Thus, the extended circulation time with enhanced bioavailability and half-life of nanoparticular ACPA is crucial for its therapeutic performance in the tumor area. We assumed that a novel high technology-controlled release system increasing the bioavailability of ACPA compared to free ACPA could be transferred to the clinic when validated in vivo. Plasma profile of ACPA and ACPA-loaded PCL-based nanomedicine by LC-MS/MS and complete blood count (CBC) was assessed in wild-type Balb/c mice. Tumor growth in nanomedicine-applied NSCLC-induced athymic nude mice was assessed using bioluminescence imaging (BLI) and caliper measurements, histomorphometry, immunohistochemistry, TUNEL assay, and Western blot on days 7-21. Injectable NanoACPA increased its systemic exposure to tissues 5.5 times and maximum plasma concentration 6 times higher than free ACPA by substantially improving bioavailability. The potent effect of NanoACPA lasted for at least two days on ectopic NSCLC model through Akt/PI3K, Ras/MEK/Erk, and JNK pathways that diminished Ki-67 proliferative and promoted TUNEL apoptotic cell scores on days 7-21. The output reveals that NanoACPA platform could be a chemotherapeutic for NSCLC in the clinic following scale-up GLP/GMP-based phase trials, owing to therapeutic efficacy at a safe low dose window.

Effects of buffers on spray-freeze-dried/lyophilized high concentration protein formulations.
Solid-state protein formulations are known to exhibit enhanced storage stability compared to their liquid dosage form counterparts. pH is one of the factors affecting the stability of protein formulations. The pH of protein formulations in the solution could be influenced by the buffer used, directly impacting their solid-state stability. During lyophilization, buffer components may interact with other formulation components present in the protein formulations, causing a pH shift. This study aimed to investigate the effects of phosphate buffer and amino acid buffers (such as histidine and/or arginine) on the physical properties and accelerated storage stability of spray freeze-dried or lyophilized protein formulations. A model protein, bovine serum albumin (BSA), was used to prepare high-concentration protein formulations. The formulations consisted of BSA, trehalose, and mannitol in an 80:15:5 ratio (w/w), respectively. Various buffers were utilized in the preparation of protein formulations, and the resultant solid formulations underwent screening via accelerated stability study using size exclusion chromatography (SEC). The combination of phosphate and arginine buffers resulted in increased monomer loss in the accelerated storage stability study. Additional characterizations, including solid-state Fourier transform infrared spectroscopy (ssFTIR) and powder X-ray diffraction (PXRD), were conducted. While these analyses did not definitively elucidate the mechanism behind the observed instability, their outcomes provide valuable insights for further investigation, highlighting the need for future research in this area.

Mesenchymal stem cell-delivered paclitaxel nanoparticles exhibit enhanced efficacy against a syngeneic orthotopic mouse model of pancreatic cancer.
Pancreatic cancer is considered the deadliest among various solid tumors, with a five-year survival rate of 13 %. One of the major challenges in the management of advanced pancreatic cancer is the inefficient delivery of chemotherapeutics to the tumor site. Even though nanocarriers have been developed to improve tumoral delivery of chemotherapeutics, less than 1 % of the drugs reach tumors, rendering inadequate concentration for effective inhibition of tumors. As a potential alternative, mesenchymal stem cells (MSCs) can effectively deliver their cargo to tumor sites because of their resistance to chemotherapeutics and inherent tumor tropism. In this study, we used MSCs for the delivery of dibenzocyclooctyne (DBCO)-functionalized paclitaxel (PTX)-loaded poly(lactide-co-glycolide)-b-poly (ethylene glycol) (PLGA) nanoparticles. MSCs were modified to generate artificial azide groups on their surface, allowing nanoparticle loading via endocytosis and surface conjugation via click chemistry. This dual drug loading strategy significantly improves the PTX-loading capacity of azide-expressed MSCs (MSC-Az, 55.4 pg/cell) compared to unmodified MSCs (28.1 pg/cell). The in vitro studies revealed that PTX-loaded MSC-Az, nano-MSCs, exhibited cytotoxic effects against pancreatic cancer without altering their inherent phenotype, differentiation abilities, and tumor tropism. In an orthotopic pancreatic tumor model, nano-MSCs demonstrated significant inhibition of tumor growth (p < 0.05) and improved survival (p < 0.0001) compared to PTX solution, PTX nanocarriers, and Abraxane. Thus, nano-MSCs could be an effective delivery system for targeted pancreatic cancer chemotherapy and other solid tumors.
