Journal of Chemistry has retracted the article titled “DFT Based QSAR Study of Enzyme Ribonucleoside Diphosphate Reductase” [1], as it is essentially identical in technical content with a previously published paper titled “QSAR Study on Inhibitors of Enzyme Ribonucleoside Diphosphate Reductase,” by Ved Prakash Singh, Durga Nath Dhar, and Ravi Kumar Srivatsava in Asian Journal of Chemistry, Volume 21, Issue 10, pp. 2052–2058, 2009 [2].
