When a paper is retracted, so is its previous correction–sometimes

1-s2.0-S0968089612X0018X-cov150hSometimes, the path to correcting the scientific record takes a few turns. In the case of a paper about a new cancer compound, authorship issues led to a correction and, ultimately, a retraction — along with a double-back to retract the earlier correction.

We reported on the first part of the story back in January: A 2011 paper that described a novel compound that could work as a drug for the side effects of chemotherapy was corrected in 2012 to add additional authors. But once the authors realized their supposedly novel compound had actually been synthesized by another author, they decided to retract the paper from Bioorganic and Medicinal Chemistry earlier this year, concluding “these facts made the paper inappropriate and unfaithful.”

Apparently, around the same time, the authors decided to retract the earlier correction, as well:

Takeda group retracts paper after realizing “novel” compound had already been synthesized…by a colleague

BMC_CoverA group of scientists at Takeda Pharmaceutical, including vice president Yoshinori Ikeura, has lost a paper after realizing that their “novel” compound had been previously synthesized by another Takeda researcher.

The 2011 paper, published in Elsevier journal Bioorganic & Medicinal Chemistry, was the subject of a 2012 corrigendum adding two authors to the paper. The retraction appeared online in December of this year.

Seems like they didn’t add enough authors, though. Continue reading Takeda group retracts paper after realizing “novel” compound had already been synthesized…by a colleague

Seventh retraction appears for author who tampered with investigation

bioorganicsKarel Bezouška, who tried tampering with an investigation into his work by breaking into a lab refrigerator, has had a seventh paper retracted.

Here’s the notice for “Carboxylated calixarenes bind strongly to CD69 and protect CD69+ killer cells from suicidal cell death induced by tumor cell surface ligands,” which was first published in Bioorganic & Medicinal Chemistry in 2010: Continue reading Seventh retraction appears for author who tampered with investigation
