A Dual-Function Hemicyanine Material with Highly Efficient Photothermal and Photodynamic Effect Used for Tumor Therapy. Adv Healthc Mater 2024; 13:e2303432. [PMID: 38069831 DOI: 10.1002/adhm.202303432] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Revised: 11/25/2023] [Indexed: 12/17/2023]
Abstract
Small molecular organic optical agents with synergistic effects of photothermal therapy (PTT) and photodynamic therapy (PDT), hold credible promise for anti-tumor therapy by overcoming individual drawbacks and enhancing photon utilization efficiency. However, developing effective dual-function PTT-PDT photosensitizers (PSs) for efficient synergistic phototherapy remains challenging. Here, a benz[c,d]indolium-substituted hemicyanine named Rh-BI, which possesses a high photothermal conversion efficiency of 41.67% by exhaustively suppressing fluorescence emission, is presented. Meanwhile, the rotating phenyl group at meso-site induces charge recombination to enhance the molar extinction coefficient up to 13.58 × 104 M-1cm-1, thereby potentiating the photodynamic effect. Under 808 nm irradiation, Rh-BI exhibits significant phototoxicity in several cancer cell types in vitro with IC50 values as low as ≈0.5 µM. Moreover, treatment of 4T1 tumor-bearing mice with Rh-BI under laser irradiation successfully inhibits tumor growth. In a word, an effective strategy is developed to build PTT-PDT dual-functional optical materials based on hemicyanine backbone for tumor therapy by modulating conjugation system interaction to adjust the energy consumption pathway.

Colloids Surf B Biointerfaces 2024; 233:113611. [PMID: 37924748 DOI: 10.1016/j.colsurfb.2023.113611] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Revised: 10/19/2023] [Accepted: 10/20/2023] [Indexed: 11/06/2023]
Abstract
Although organic photothermal agents (PTAs) have been extensively studied in preclinical cancer photothermal therapy (PTT), the internal mechanism, particularly the impact of side chains on photothermal performance, remains inadequately investigated. Herein, we conducted a systematic comparison of the photothermal properties between two organic molecules, namely O-IDTBR with four n-octyl chains and EH-IDTBR with four 2-ethylhexyl chains. With the same conjugated main structure, both O-IDTBR and EH-IDTBR exhibited nearly identical absorption properties (with a peak at 629 nm) in their molecular states. Interestingly, after the formation of nanoparticles (NPs), O-IDTBR NPs with linear alkyl chains exhibit a further red-shifted absorption onset (peak at 711 nm) compared to EH-IDTBR NPs (peak at 662 nm) with branched alkyl chains. Additionally, the photothermal conversion efficiency of O-IDTBR NPs was calculated of 33.7%, which is higher than that of EH-IDTBR NPs (27.7%). This can be attributed to the fact that linear alkyl chains of O-IDTBR NPs promote more intramolecular motions at the aggregated state by extending intermolecular distance and distorting molecular conformation. Therefore, the nonradiative thermal deactivation-induced photothermal property can be further enhanced. Through both in vitro and in vivo experiments, O-IDTBR NPs exhibit effective PTT effect and excellent biocompatibility. This study not only introduces a novel PTA but also opens new avenues for exploring organic optical nano-agents through side-chain engineering to adjust intramolecular motions at the aggregated state.
