Sericin is a candidate for developing durable and precise 3D-printed structures due to its natural origin and intrinsic properties like film-forming ability and cross-linking potential. Its biocompatibility makes it suitable for medical applications, such as targeted delivery of anticancer drugs or creation of therapeutic supports directly on affected skin, orthodontic and cosmetic biomaterials, disease modulation, wound healing, antioxidant and antimicrobial applications, and regenerative medicine. Additionally, sericin can strengthen and stabilize printed structures while maintaining environmental integrity, aligning with the growing demand for eco-friendly materials in advanced manufacturing. However, formulating sericin-based resins for DLP printing presents challenges, including optimizing cross-linking and curing processes for obtaining desired properties of material. Overcoming these challenges could unlock the full potential of sericin in diverse fields, such as tissue engineering, where biocompatibility and precise structural integrity are critical. This review investigates the potential of sericin-based resins for 3D printing, emphasizing the protein’s compatibility with photopolymerizable systems and its capacity to improve the overall performance of DLP-printed materials. Further research is essential to refine sericin-based formulations, enabling their broader application in 3D printing technologies. By examining the unique characteristics of sericin, including its origins and material properties, this review underscores the protein's potential to drive innovation in sustainable manufacturing. Ultimately, sericin offers a viable alternative to synthetic resins and holds promise for advancing both biomedical and environmental applications through innovative 3D printing technologies.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":6925,"journal":{"name":"AAPS PharmSciTech","volume":"26 5","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143845663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to investigate the release of dissolved curcumin from a new injectable hyaluronic acid/quince seed gum (HA/QSG) hydrogel. Curcumin possesses numerous biological activities, including anti-cancer, antioxidant, antimicrobial, and anti-inflammatory properties. However, due to its very low water solubility, its bioavailability is poor. To address this, curcumin was encapsulated in three inclusion complexes: Cur 1:2 β-CD, Cur 1:4 β-CD, and Cur 1:6 β-CD. These Cur-β-CD inclusion complexes were lyophilized and converted into a water-soluble form. The curcumin, bisdemethoxycurcumin, and desmethoxycurcumin content of the obtained lyophilized Cur-β-CD complexes were analyzed using the HPLC method. HA-QSG hydrogels were loaded with Cur 1:2 β-CD inclusion complex in compositions of 0.75% (w/w), 0.50% (w/w), and 0.25% (w/w). The dissolution profiles of the HA-QSG hydrogels were examined in a pH 6.8 phosphate buffer medium, used as the swelling medium in intra-articular hydrogels. The initial burst of the 0.75% (w/w) hydrogel reached 9% release within the first 15 min, whereas the 0.25% (w/w) hydrogel exhibited only 6% release during the same period. The 0.75%(w/w) and 0.50% (w/w) hydrogels displayed very similar dissolution profiles, with a slightly faster release in the early stages of dissolutions, compared to the 0.25%(w/w) Cur β-CD-HA-QSG hydrogel. The 0.25%(w/w) Cur β-CD-HA-QSG hydrogel demonstrated a relatively slower release rate particularly during the initial stage of dissolution period. However, all three formulations reached approximately 98% release within 24 h. While the 0.75%(w/w) and 0.50%(w/w) curcumin-loaded HA-QSG hydrogels, with their rapid initial release, may be suited for intra-articular applications requiring quick drug availability, the 0.25%(w/w) curcumin-loaded HA-QSG hydrogel, with its slower release, may be more beneficial for sustained intra-articular delivery.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":6925,"journal":{"name":"AAPS PharmSciTech","volume":"26 4","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1208/s12249-025-03095-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143749116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present work investigates advantages of combining HME with fused deposition modelling (FDM) 3-Dimensional (3D) printing in delivering the naringenin to the colon to treat inflammatory bowel disease. HME filaments were made using a pH-sensitive polymer hydroxypropyl methylcellulose acetate succinate for the localized delivery of naringenin at the colonic pH. Polyethylene glycol (PEG – 4000) and Aerosil 200 were incorporated as plasticizer and flow modulator respectively, to facilitate the extrusion process. Naringenin was converted to amorphous form as confirmed by differential scanning calorimetry and powder x-ray diffraction. The optimized filament showed 0.03, 11.52 and 77.80% drug release at pH 1.2, 6.8 and 7.4 respectively. The tablets produced with the optimized filament by compression and 3D printing also confirmed the presence of naringenin in amorphous form and demonstrated pH-dependent release followed by zero-order release independent of the concentration. The dissolution profiles of FDM 3D printed (3DP) tablets with varying dimensions and infill densities suggested that both significantly influenced drug release from the tablets without altering the composition of tablets, indicating the potential application of 3D printing technology in developing personalized medicine according to patient requirements.
