AI Article Synopsis
- * Researchers developed a transferosomal gel containing TFD and QCN, which showed good drug release and enhanced skin permeability in lab studies, indicating it could deliver medication directly to joint tissues.
- * The combination gel was found to be non-toxic and effective in reducing inflammatory markers and joint swelling in rat models, suggesting it can minimize side effects compared to oral treatments.
Article Abstract
Rheumatoid arthritis (RA) is an immune-mediated inflammatory disease. Combination therapy is anticipated to surpass monotherapy by targeting multiple pathways involved in RA progression. The present aim is to develop a combination of Teriflunomide (TFD) and Quercetin (QCN) loaded transferosomal gel to enhance permeability and achieve localized delivery to joint tissues. TFD or QCN transferosomes were optimized employing a 3-level, 3-factorial design Box-Behnken design (BBD). The transferosomes exhibited sustained in-vitro drug release. The topical combination gel underwent thorough evaluation of rheology, and also ex-vivo studies showed enhanced permeability through rat skin. The synergistic combination of TFD and QCN effectively suppressed NO, TNF-α and IL-6 levels in in-vitro RAW 264.7 cells. The cytotoxicity in HaCaT cell lines indicates non-toxicity of the gel, further confirmed by skin irritation study conducted in rats. The in-vivo anti-arthritic activity was evaluated in complete freund's adjuvant induced rat paw edema model illustrates the effectiveness of the combination transferosomal gel compared to other treatment groups. In conclusion, the topical delivery of TFD and QCN combination transferosomal gel demonstrated anti-arthritic activity through localized delivery whichallows for dose reduction, thereby may reduce the systemic drug exposure and mitigate the side effects associated with oral administration of TFD.

: Lung cancer is an aggressive disease with rapid progression and a high rate of metastasis, leading to a significantly poor prognosis for many patients. While chemotherapy continues to serve as a cornerstone treatment for a large proportion of lung cancer patients, expanding preclinical and clinical evidence indicates that chemotherapy may promote tumor metastasis and cause side effects. : We develop an injectable bait-and-hook hydrogel (BH-gel) for targeted tumor cell eradication, which embedded doxorubicin liposomes as cytotoxic agents and CXCL12 as a chemoattractant to capture and kill tumor cells.

This study aims to develop a thermoresponsive biomaterial system of irinotecan (IRT) and curcumin (CUR) nano-transferosomal gel (IRT-CUR-NTG) for targeting colorectal cancer (CRC). The IRT-CUR-NTs were statistically optimized and loaded into poloxamer-based thermosensitive gel. Transmission electron microscopy (TEM), Differential scanning calorimetry (DSC) and Fourier-transform infrared spectroscopy (FTIR) of the IRT-CUR-NTs were performed, whereas pH, gelation time, gelation temperature, gel and mucoadhesive strength of the IRT-CUR-NTG were investigated.

Oleic acid liposomes (OALs) are novel vesicular carriers ofunsaturated fatty acids and their corresponding ionized species, arranged within an enclosed lipid bilayer. This study aimed to encapsulate moxifloxacin HCl (MOX), a broad-spectrum antibacterial drug into OALs for effective treatment of Methicillin-resistant Staphylococcus aureus (MRSA) infection through topical application. Various OALs were formulatedby combining varied quantities of phosphatidylcholine (PC), oleic acid (OA), and cholesterol (CH) with 50 mg of MOX.

Functionalized lipid analogs are a versatile tool for studying lipid localization, metabolism and interactions in cells. As a common follow-up research, in vitro experiments are utilized to confirm specific interactors and characterize protein-lipid interactions. Here, we describe protocols that rely on commercially available photoactivatable and clickable lipids in reconstituted systems to capture protein-lipid interactions and detect lipid transport between purified proteins.

Background: Norfloxacin (NFX) is a wide-spectrum antibacterial agent that suffers from low water solubility and first-pass metabolism. This diminishes its oral bioavailability by 60-70%.
Objective: This work aims to formulate a topical gel of NFX-loaded lipid polymer hybrid nanoparticles (NFX-LPHNPs) that combine the merits of liposomes and polymeric nanoparticles to overcome these problems.
