What the research found
ScienceDaily dated its page 3 November 2026. The feed clock falls on 4 November in Bangkok. The report covers a Nature Communications paper from Katsunori Tanaka's group at RIKEN. They enclosed a palladacycle in albumin so glutathione would not shut off the palladium catalyst, then exposed cultured human liver, cervical, breast, and lung cancer cells, plus a noncancerous cell line, for 48 hours. Phenanthridinone showed up in the cancer lines and not in the noncancerous line. A later version of the reaction formed a toxic phenanthridinone derivative inside cultured liver cancer cells, and those cells showed damage. In a laboratory blood test, the toxic compound did not form. The authors attribute that to carbon monoxide already bound to hemoglobin. The paper has no animal experiment and no patient series.
