Abstract
Effective loading and delivering the wound healing-based materials to the wound site and area with an optimum concentration and limited cytotoxicity are essential for a complete and fast healing process. Here, we have designed Zn/Al-LDH nanoparticles-loaded CMC films for encapsulation and delivery of gallic acid (GA) in order to develop an effective and efficient wound-healing scaffold. The physicochemical properties of the prepared Zn/Al-LDH nanohybrids were thoroughly characterized by several characterization techniques, such as FESEM, Hi-TEM, FTIR, and XRD techniques. The thermal properties of the scaffolds were evaluated by DSC and TGA analysis. The release profiles of GA from fabricated films were studied over 8 h by UV-vis spectroscopy. In vitro drug release studies in PBS solutions with pH 7.4 showed a mono-phasic profile in which the liberation of the drug mainly occurred by scaffold erosion and increased by increasing the experiment period. The in vitro antibacterial activity of Zn/Al-LDH-GA-loaded CMC films was assessed by disk diffusion and cell viability contact tests. The results showed the desired antibacterial activity against Staphylococcus aureus and Escherichia coli bacteria. Incorporating GA within CMC and CMC-Zn/Al-LDH films rereleased good cytocompatibility at the studied incubation time and different concentrations toward human normal HFF cell line than the free drug. The results of the present study indicated that the Zn/Al-LDH and Zn/Al-LDH-GA-loaded CMC have promising wound healing features to further develop a better future for clinical remedy of the different non-healing and hard-to-heal wounds.

Hyaluronic acid engineered gallic acid embedded chitosan nanoparticle as an effective delivery system for treatment of psoriasis. ENVIRONMENTAL RESEARCH 2023; 238:117086. [PMID: 37683783 DOI: 10.1016/j.envres.2023.117086] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Revised: 08/30/2023] [Accepted: 09/05/2023] [Indexed: 09/10/2023]
Abstract
Psoriasis is a deleterious auto-immune disorder which seriously harms the patients physical and mental health. CD44 are found to be over-expressed on psoriatic lesions which are highly responsible for epidermal hyperproliferation and inflammation. Gallic acid (GA), a phenolic acid natural compound has potential inhibitory impact on pro-inflammatory transcription factors. However, the penetration across skin and availability is low when applied topically, making the treatment extremely challenging. Considering such factors, we developed GA loaded chitosan nanoparticles and modified with hyaluronic acid (HA) (HA@CS-GA NP) to assess the therapeutic potential against psoriasis. The formulations were characterized by DSC, zetasizer and TEM for assuring the development of nanosystems. GA loaded CS NP had a particle size of 207.2 ± 0.08 nm while after coating with HA, the size increased to 220.1 ± 0.18 nm. The entrapment efficiency was 93.24 ± 0.132% and drug loading of 73.17 ± 0.23%. The in vitro cell viability assessment study confirmed enhanced anti-proliferative effect of HA@CS-GA NP over plain GA which is due to high sensitivity towards HaCaT cell. The in vivo results on imiquimod induced psoriasis model indicated that CD44 receptor mediated targeted approach of HA@CS-GA NP gel had great potential in restricting the keratinocyte hyperproliferation and circumventing psoriasis. For the therapy of further skin-related conditions, HA modified nanoparticles should be investigated extensively employing genes, antibodies, chemotherapeutics, or natural substances.
