Name the journal that publish, the discovery of the first small-molecule inhibitors of the Streptococcus pyogenes Cas9 (SpCas9) protein by the team of researchers headed by Amit Choudhary.

In the journal 'Cell' researchers authored that the discovery of the first small-molecule inhibitors of the Streptococcus pyogenes Cas9 (SpCas9) protein could enable more precise control over CRISPR-Cas9-based genome editing. i. The research was headed by Amit Choudhary of the Broad Institute, Harvard Medical School, and Brigham and Women's Hospital. These first small-molecule CRISPR-Cas9 inhibitors are much smaller than the previously discovered anti-CRISPR proteins.
