During the corresponding author's transfer from Dongguk University to Sungkyunkwan University in March 2006, data from the previous University was transferred to the corresponding author's new computer. During this data transfer there was a mixing of EMSA data from experiments involving Quercetin (QC), Ochnaflavone (OC), Tanshinone (TS), Crytotanshinone (CT), BMK, and natural extracts. The mixed EMSA data was inadvertently incorporated in more than one publication. Figure 6 has been corrected to new data with re‐confirmation. J. Cell.

6. Effect of OC on the TNF‐α‐induced DNA binding activities of MMP‐9, NF‐κB, and AP‐1 motif in HASMC. Cells were pretreated with indicated OC for 40 min in serum‐free medium, were incubated with TNF‐α (100 ng/ml) for 24 h. Nuclear extracts were analyzed by EMSA for the activated NF‐κB (A) and AP‐1 (B) using radiolabeled oligonucleotide probes, respectively. Indicated values are means of three triplicate experiments.     

Investigation of Optical Spectroscopic and Computational Binding Mode of Bovine Serum Albumin with 1, 4‐Bis ((4‐((4‐Heptylpiperazin‐1‐yl) Methyl)‐1H‐1, 2, 3‐Triazol‐1‐yl) Methyl) Benzene

A newly synthesized 1, 4‐bis ((4‐((4‐heptylpiperazin‐1‐yl) methyl)‐1H‐1, 2, 3‐triazol‐1‐yl) methyl) benzene from the family of piperazine derivative has good anticancer activity, antibacterial and low toxic nature; its binding characteristics are therefore of huge interest for understanding pharmacokinetic mechanism of the drug. The binding of piperazine derivative to bovine serum albumin (BSA) was investigated using fluorescence spectroscopy. The molecular distance r between the donor (BSA) and acceptor (piperazine derivative) was estimated according to Forster's theory of nonradiative energy transfer. The physicochemical properties of piperazine derivative, which induced structural changes in BSA, have been studied by circular dichroism and those chemical environmental changes were probed using Raman spectroscopic analysis. Further, the binding dynamics was expounded by synchronous fluorescence spectroscopy and molecular modeling studies explored the hydrophobic interaction and hydrogen bonding results, which stabilize the interaction.     

N‐[2‐[(3‐Chlorophenyl)amino]‐phenyl]‐3‐(difluoromethyl)‐1‐methyl‐1H‐pyrazole‐4‐carboxamide: Synthesis,Crystal Structure,Molecular Docking and Biological Activities

In continuation of our previous research on the development of novel pyrazole‐4‐carboxamide with potential antifungal activity, compound SCU2028 , namely N‐[2‐[(3‐chlorophenyl)amino]phenyl]‐3‐(difluoromethyl)‐1‐methyl‐1H‐pyrazole‐4‐carboxamide, was synthesized by new method, structurally characterized by IR, HR‐ESI‐MS, ¹H‐ and ¹³C‐NMR spectra and further identified by single‐crystal X‐ray diffraction. In pot tests, compound SCU2028 showed good in vivo antifungal activity against Rhizoctonia solani (R. solani) and IC₅₀ value of it was 7.48 mg L^?1. In field trials, control efficacy of compound SCU2028 at 200 g.a.i. ha^?1 was 42.30 % on the 7^th day after the first spraying and 68.10 % on the 14^th day after the second spraying, only slightly lower than that of thifluzamide (57.20 % and 71.40 %, respectively). Further in vitro inhibitory activity showed inhibitory ability of compound SCU2028 was 45‐fold higher than that of bixafen and molecular docking of compound SCU2028 to SDH predicted its binding orientation in the active site of the target protein SDH. These results suggested that compound SCU2028 was a potential fungicide for control of rice sheath blight.
