Singzyme: A New Enzyme-Like Molecule Shows Promise for Cancer Therapy (in a Dish)

Researchers developed a new photosensitizer molecule, superphane 1 or "singzyme", that effectively kills cancer cells in vitro by generating reactive oxygen species and disrupting redox homeostasis, leading to both apoptosis and ferroptosis. Superphane 1 mimics the activity of natural enzymes, such as NADH oxidase and GSH oxidase, showing enhanced photosensitivity and photocatalytic activity compared to control molecules due to the "super cage effect".

Possible Conflicts of Interest

None identified

Identified Weaknesses

Lack of in vivo studies

The in vitro experiments demonstrate promising results, but further in vivo studies are essential to validate the therapeutic efficacy and biocompatibility of superphane 1 in a living organism.

Lower catalytic efficiency compared to natural enzymes

While superphane 1 exhibits promising enzyme-like activities, its catalytic efficiency is still lower than natural enzymes, indicating a need for further optimization.

Long-term stability and toxicity assessment

The long-term stability and potential toxicity of superphane 1 in biological systems require further investigation.

Rating Explanation

This study presents a well-designed and executed investigation into a novel photosensitizer with potential therapeutic applications. The synthesis, characterization, and in vitro testing of superphane 1 demonstrate its effectiveness in inducing cancer cell death through a combination of apoptosis and ferroptosis. The 'super cage effect' is a novel concept with potential for broader application in photocatalysis. However, the lack of in vivo studies warrants a rating of 4, pending further research to confirm the therapeutic efficacy in living organisms.
