Round 1

Reviewer 1 Report

Koga et al designed and synthetized new AR antagonists candidates and evaluated their growth-inhibitory activity on wild-type (SC-3) and T877A (LNCAP) AR expressing prostate cells.

I do not have major commentss concerning the work. My recommendation is minor revision.

I have only one minor remark. In tables 1, 2 and 3, the IC50 antiandrogen values o are indicated in M. They should be replaced by µM.

They should be replaced by μM.

Our response: Thank you for your comments. This is our simple mistake, and revised the unit of concentration of IC₅₀ in Tables 1 – 3.

2. Reviewer’s comment:

Reviewer 3 Report

Authors prepared large series of new coumarinamides and successfully tested them as androgen antagonists. Great benefit of this work is strong multidisciplinary approach, which can enable to preparation of novel nonclassical pharmacophore and describe the mechanism of their effect. About my opinion these compounds represent perspective agents for cancer treatment. Also, their synthesis biological studies and calculation method is described well. And thereby I can recommend publication of presented manuscript in this journal.
