Syntheses and Identification of New Dithiophosphinic Acid Complexes and their Potential as Photodynamic Agents in Cancer Therapy.
Article in Medicinal chemistry (Shariqah (United Arab Emirates)), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe photo-efficacy of oncological phototherapy for both internal and external tumors is encouraging. When light and photochemotherapeutic drugs are applied together, precise cancer targeting, minimal invasiveness, and innovative modes of action are made possible. Current developments in photoactive compounds and new light sources are promising for further advancement.
objectiveWhen designing photosensitizers, metal complexes may be advantageous since the metal can enhance stability and photocytotoxicity while facilitating their localization and quantification. The absorption spectra of photosensitizers limit their excitation wavelengths, which impact light tissue penetration that differs in various organs. Since longer wavelength light penetrates deeper, PDT is typically carried out at wavelengths greater than 620 nm. Additionally, employing lower intensity (>4-8 J/cm
methodsLow-level laser therapy exposure was used to assess the dithiophosphinic acid complexes' photodynamic treatment efficacy in MCF-7 cells. Following the administration of the complexes at concentrations within IC
resultsDTPA complexes have shown effectiveness as photodynamic agents in cancer therapy, with Ni(II) and Ni(II)-pyridine complexes demonstrating significant cytotoxicity against cancer cells.
conclusionLight-activated cancer cell therapies are promising, and the synthesized complexes affect the cell cycle and apoptosis-regulating proteins. The compounds can be employed as anticancer agents and a fine starting template for photodynamic drug design.
