Author correction to ‘Design, synthesis and biological evaluation of chalcone analogues with novel dual antioxidant mechanisms as potential anti-ischemic stroke agents’ [Acta Pharmaceutica Sinica B 9 (2019) 335–350]

The authors regret that there was a picture error in Fig. 5D and Fig. 5E, owing to the authors’ mistakes of copying and pasting in the process of assembling figures and making a diagram. In Fig. 5D, the image of the edaravone 6 h group (ED-6h group) was repeated with the model group (NS group), and thus the image of the ED-6h group needs to be corrected. In Fig. 5E, the data of the edaravone 3h group (ED-3h group) was repeated with the 33 6h group (33-6h group), and thus the data of the ED-3h group needs to be corrected. The raw data of correct images of ED-6h group in Fig. 5D and Fig. 5E are provided, as well as the raw data of NS group. The authors revise Fig. 5D and Fig. 5E as below. The revisions do not affect any results and conclusions of the current work.

The authors apologize for any inconvenience caused to the journal and readers.

The raw data of correct image of ED-6h group and NS group in Fig. 5D are:

Animal name	Total distance (mm)	Animal name	Total distance (mm)
ED-6h-1	2010.43	NS-1	5764.30
ED-6h-2	1715.27	NS-2	5879.49
ED-6h-3	2356.93	NS-3	467.74
ED-6h-5	11232.63	NS-4	844.65
ED-6h-6	4979.84	NS-5	2405.69
ED-6h-7	1710.57	NS-6	5764.86
ED-6h-8	5064.17	NS-7	7649.27
		NS-8	4258.74

The raw data of correct histogram in Fig. 5E are:

Animal name	Total distance (mm)	Animal name	Total distance (mm)

33-6h-2	11431.37	ED-3h-2	9911.05
33-6h-3	5041.82	ED-3h-3	8165.77
33-6h-4	11770.41	ED-3h-4	19645.20
33-6h-5	17542.43	ED-3h-5	1888.77
33-6h-6	10201.09	ED-3h-6	13478.10
33-6h-7	8366.35	ED-3h-7	12981.00
33-6h-8	11312.31

After the correction of 5D, the Fig. 5 is:
