Eur J Med Chem 2024; 272:116474.

Abstract
Small molecule photosensitizers for combined in vivo tailored cancer diagnostics and photodynamic/photothermal therapy are desperately needed. Monoamine oxidase A (MAO-A)-activated therapeutic and diagnostic compounds provide great selectivity because MAO-A can be employed as a biomarker for associated Tumors. In order to screen photosensitizers with photodynamic therapeutic potential, we have created a range of near-infrared fluorescent molecules in this work by combining dihydroxanthene parent with various heterocyclic fluorescent dyes. The NIR fluorescent diagnostic probe, DHMQ, was created by combining the screened fluorescent dye matrices with the propylamino group, which is the recognition moiety of MAO-A, based on the oxidative deamination mechanism of the enzyme. This probe has a low toxicity level and can identify MAO-A precisely. It has the ability to use fluorescence imaging on mice and cells to track MAO-A activity in real-time. It has strong phototoxicity and can produce singlet oxygen when exposed to laser light. The temperature used in photothermal imaging can get up to 50 °C, which can harm tumor cells permanently and have a positive phototherapeutic impact on tumors grown from SH-SY5Y xenograft mice. The concept of using MAO-A effectively in diseases is expanded by the MAO-A-activated diagnostic-integrated photosensitizers, which offer a new platform for in vivo cancer diagnostics and targeted anticancer treatment.

Abstract
Heavy-atom-free photosensitizers are potentially suitable for use in photodynamic therapy (PDT). In this contribution, a new family of unsymmetrical benzothieno-fused BODIPYs with reactive oxygen efficiency up to 50% in air-saturated toluene was reported. Their efficient intersystem crossing (ISC) resulted in the generation of both 1O2 and O2-• under irradiation. More importantly, the PDT efficacy of a respective 4-methoxystyryl-modified benzothieno-fused BODIPY in living cells exhibited an extremely high phototoxicity with an ultralow IC50 value of 2.78 nM. The results revealed that the incorporation of an electron-donating group at the α-position of the unsymmetrical benzothieno-fused BODIPY platform might be an effective approach for developing long-wavelength absorbing heavy-atom-free photosensitizers for precision cancer therapy.

[PMID: 38190797 DOI: 10.1016/j.bioorg.2024.107097] [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: 11/11/2023] [Revised: 12/31/2023] [Accepted: 01/02/2024] [Indexed: 01/10/2024]
Abstract
To discover new photosensitizers with long wavelength UV-visible absorption, high efficiency, and low side effects for photodynamic therapy, here, a series of novel thieno[3,2-b]thiophene-fused BODIPY derivatives were designed, synthesized and characterized. These compounds had a distinct absorption band at 640-680 nm, fluorescence emission at 650-760 nm, and good solubility with anti-aggregation effects. These new compounds possessed obvious singlet oxygen generation ability and photodynamic anti-Eca-109 cancer cells activities in vitro. Among them, compound II4 could be well uptaked by Eca-109 cells, and result in the apoptosis after laser irradiation, and have outstanding photodynamic efficiency both in vitro and in vivo. Therefore, II4 could be considered as a potential photosensitizer drug candidate for PDT and photo-imaging.
