摘要

联合癌症治疗受益于可注射的水凝胶，用于局部、受控的药物输送。研究了巯基修饰透明质酸（HASH）与乙烯砜修饰β-环糊精（CDVS）交联形成的巯基共轭水凝胶。通过不同HASH分子量（23或99 kDa）和cdv改性（16%或33%），合成了4种配方（23Gel-16、23Gel-33、99Gel-16、99Gel-33）。流变学分析证实，随着分子量的增加和改性（99Gel-33 > 99Gel-16 > 23Gel-33 > 23Gel-16），粘弹性增强。该系统能够联合递送阿霉素（DOX）和卡维罗（CRV），表现出肿瘤反应性降解和可调节的释放。在模拟肿瘤条件下，DOX释放加速（46小时100%，PBS为58.7%），而CRV表现为初始爆发，随后持续释放。水凝胶促进间充质干细胞增殖，有效抑制三阴性乳腺癌细胞。这种可注射的、肿瘤反应性的水凝胶系统为微创、个性化的癌症治疗提供了一个有前途的平台。

Localized Cancer Treatment Using Thiol–Ene Hydrogels for Dual Drug Delivery

Combinatorial cancer therapy benefits from injectable hydrogels for localized, controlled drug delivery. This study presents a thiol–ene conjugated hydrogel formed by cross-linking thiol-modified hyaluronic acid (HASH) with vinyl sulfone-modified β-cyclodextrin (CDVS). Four formulations (23Gel-16, 23Gel-33, 99Gel-16, 99Gel-33) were synthesized by varying HASH molecular weight (23 or 99 kDa) and CDVS modification (16% or 33%). Rheological analysis confirmed enhanced viscoelasticity with increasing molecular weight and modification (99Gel-33 > 99Gel-16 > 23Gel-33 > 23Gel-16). The system enabled combinatorial delivery of doxorubicin (DOX) and carvacrol (CRV), exhibiting tumor-responsive degradation and tunable release. DOX release accelerated under tumor-mimicking conditions (100% in 46 h vs 58.7% in PBS), while CRV showed an initial burst followed by sustained release. The hydrogel promoted mesenchymal stem cell proliferation and effectively inhibited triple-negative breast cancer cells. This injectable, tumor-responsive hydrogel system offers a promising platform for minimally invasive, personalized cancer therapy.
