The experimental compound 1-Fe showed two reported activities in a 2013 study: it acted as a catalytic antioxidant and inhibited an enzyme involved in cholesterol production. The findings came from biochemical experiments and work with mice—not clinical evidence that the compound prevents heart disease or can replace statins.
What is 1-Fe?
1-Fe is an iron(III) complex of an amphipolar corrole, a type of molecule studied for its chemical and biological properties. The 2013 paper described it as a catalytic antioxidant: rather than being used up in a single reaction, it was reported to eliminate free radicals catalytically. That description concerns the compound’s proposed molecular activity, not a demonstrated health benefit in people.
The study was published in Chemical Communications by Adi Haber, Amona Abu-Younis Ali, Michael Aviram and Zeev Gross of Technion – Israel Institute of Technology. It was first published on 26 July 2013. Read the paper from the Royal Society of Chemistry.

What are the “two fronts”?
1. Catalytic antioxidant activity
The proposed first action was the catalytic removal of free radicals. In the contemporaneous account, corresponding author Zeev Gross said, “Our antioxidant eliminates free radicals in a catalytic fashion.” This is an attributed description of the compound’s proposed activity; it does not show that 1-Fe reduces cardiovascular risk in humans.

2. Inhibition of cholesterol synthesis
The second action involved HMG-CoA reductase, an enzyme that participates in cholesterol biosynthesis. The paper reported that 1-Fe and a non-redox-active analogue inhibited the enzyme allosterically—that is, by acting at a site other than the enzyme’s active site. It also reported reduced cholesterol-biosynthesis ability in macrophages harvested from mice treated with 1-Fe.
How is the proposed mechanism different from statins?
The 2013 news report described statins as competitive inhibitors of HMG-CoA reductase, while the corroles were reported to inhibit the same enzyme allosterically. Both mechanisms concern the same enzyme, but they are not the same way of inhibiting it. Gross summarized the proposed distinction this way: “We have found a new mode of action – corroles and statins inhibit the same enzyme, but use a different mechanism.”
Rank #2
This is a comparison of mechanisms, not of treatments. The reported findings do not establish that 1-Fe lowers cholesterol more effectively than statins, is safer, or improves patient outcomes.
What did the study establish—and what did it not?
The evidence described in the paper and its 2013 coverage is preclinical: biochemical work and animal research, including measurements in macrophages collected from treated mice. The sources report no numerical efficacy result that would support a quantified claim about the size of an effect.
Rank #3
- Reported: 1-Fe and a non-redox-active analogue allosterically inhibited HMG-CoA reductase.
- Reported: macrophages harvested from mice treated with 1-Fe had reduced cholesterol-biosynthesis ability.
- Not established by these findings: prevention of heart attacks, treatment of cardiovascular disease in people, clinical superiority to statins, or approval as a medicine.
In the news report, redox-regulation researcher Bato Korac described possible effects on cholesterol uptake, removal and synthesis. That is expert commentary about proposed metabolic effects, not an independent clinical finding.

No clinical comparison is supported by the reported evidence. The study raised a research question about whether a compound combining antioxidant activity with an effect on cholesterol synthesis might have useful therapeutic potential. It did not answer whether 1-Fe works as a treatment in people or whether it could replace statins. The available sources also do not establish whether the compound later advanced to further preclinical work or human testing.
“Fights heart disease” is therefore stronger than the evidence warrants if read as a claim about a proven treatment. The defensible takeaway is narrower: a 2013 preclinical study reported two molecular activities that researchers considered potentially relevant to cholesterol biology.
