SERP Comments:

hCES2A_IN-9 (compound 9d) is a highly potent covalent hCES2A inhibitor with cellular activity. However, further studies are needed before considering this compound as a hCES2A specific probe. Critical points are specificity and in vitro target engagement. To fulfil the criteria of covalent probes the authors should perform cell based chemoproteomics to ensure its proteome wide selectivity or alternatively the compound should be profiled in a wider panel of targets. Providing inactive control compound would be beneficial and the cytotoxicity of the compound should be evaluated on HepG2 cells.
