Abstract

Abstract: A novel water-soluble benzobisthiadiazole molecule(BBTD-PTA)as a photothermal agent was synthesized by etherification, coupling, nucleophilic substitution and quaternization. The photophysical properties were analyzed by UV-Vis-NIR absorption spectrum and steady-state fluorescence spectrum. The photothermal conversion properties were measured by a semiconductor laser combined with an infrared thermal imager. Hep G2 hepatoma cells were used as a model to evaluate the biocompatibility and photothermal therapy effect by MTT assay. The results showed that BBTD-PTA molecule was of capability of near-infrared absorption and emission. Its photothermal conversion efficiency reached 53.1%. - 引用格式:张文恺,杨术明,马永龙,等.基于EDEM的牧场推料机器人参数优化设计与试验［J］.河北大学学报(自然科学版),2026,46(3):225-236.引用格式:郭振鹏,杨魁,黄腾璇,等.苯并双噻二唑光热剂合成及抗肿瘤活性研究［J］.河北大学学报(自然科学版),2026,46(3):310-317.DOI:10.3969/j.issn.1000-1565.2026.03.009苯并双噻二唑光热剂合成及抗肿瘤活性研究郭振鹏,杨魁,黄腾璇,李玮(河北大学化学与材料科学学院,药物化学与分子诊断教育部重点实验室,河北保定 071000)摘要:采用醚化、偶联、亲核取代和季铵化等反应,合成了一种新型水溶性苯并双噻二唑光热剂(BBTD-PTA). 采用紫外-可见-近红外吸收光谱和稳态荧光光谱研究了其光物理性质. 采用808 nm激光器与红外热成像仪联用测定了其光热性质. 以人肝癌细胞Hep G2作为模型,用MTT比色法评估了BBTD-PTA的生物相容性和光热治疗能力. 结果表明:BBTD-PTA分子具有良好的近红外光吸收及发射能力,其光热转换效率为53.1%.
