Correction
As a result of a recent letter to the editor [1], we would like to make several corrections to our manuscript [2].
We would like to correct the sentence on page 1: "no studies have examined the effects of the interaction between Dp44mT and biological molecules, such as proteins and nucleic acids".This sentence should read: "information related to the effects of the interaction between Dp44mT and biological molecules such as human serum albumin (HSA) or DNA has not yet been fully and systematically studied".
Furthermore, we provide information on the correctness and purity of the synthesized Dp44mT.

Results and Discussion
We used commercially available di-2-pyridylketone and N',N'-dimethyl-3-thiosemicarbazide to synthesize Dp44mT via a condensation reaction.The reaction product (Dp44mT) was subjected to a specific re-crystallization in order to remove trace amount of N',N'-dimethyl-3-thiosemicarbazide.The purity after recrystallization was assessed by thin layer chromatography (TLC) and HPLC.The results show that high purity of more than 98.5% was achieved (Figures C1 and C2).

General Information
All the reagents and solvents used were of AR grade.The Dp44mT was prepared by reacting di-2-pyridylketone with 4'4'-dimethyl-3-thiosemicarbazide (Sigma, Shanghai, China) in absolute ethanol and allowed to cool [3].The resulting precipitate was collected by suction filtration and washing with cold ethanol.

Purity Assessment and Structure Identification
To achieve high quality, the precipitates were re-crystallized in absolute ethanol under less saturating conditions.Upon achieving room temperature, moderate amounts of water were added, and the solution was then placed at −20 • C. The formed crystalline Dp44mT was filtered with ice-cold ethanol and dried in a vacuum desiccator.The purity assessments indicated that the Dp44mT was of high purity (98.5%).
