Combined inhibition of both STAT5 proteins is a valuable approach with promising applications in tumor biology. We recently reported resorcinol bisphosphate as a moderately active inhibitor of the protein\u2010protein interaction domains, the SH2 domains, of both STAT5a and STAT5b. Here, we describe the development of resorcinol bisphosphate to Stafiba, a phosphatase\u2010stable inhibitor of STAT5a and STAT5b with activity in the low micromolar concentration range. Our data provide insights into the structure\u2010activity relationships of resorcinol bisphosphates and the corresponding bisphosphonates for use as inhibitors of both STAT5a and STAT5b.<\/jats:p>","DOI":"10.1002\/cbic.202200553","type":"journal-article","created":{"date-parts":[[2022,10,27]],"date-time":"2022-10-27T10:24:20Z","timestamp":1666866260000},"update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Stafiba: A STAT5\u2010Selective Small\u2010Molecule Inhibitor"],"prefix":"10.1002","volume":"24","author":[{"given":"Katrin S.","family":"Eckhardt","sequence":"first","affiliation":[{"name":"Leipzig University Institute of Organic Chemistry Johannisallee 29 04103 Leipzig Germany"}]},{"given":"Theresa","family":"M\u00fcnzel","sequence":"additional","affiliation":[{"name":"Leipzig University Institute of Organic Chemistry Johannisallee 29 04103 Leipzig Germany"}]},{"given":"Julian","family":"Gr\u00e4b","sequence":"additional","affiliation":[{"name":"Leipzig University Institute of Organic Chemistry Johannisallee 29 04103 Leipzig Germany"}]},{"ORCID":"http:\/\/orcid.org\/0000-0003-3109-7696","authenticated-orcid":false,"given":"Thorsten","family":"Berg","sequence":"additional","affiliation":[{"name":"Leipzig University Institute of Organic Chemistry Johannisallee 29 04103 Leipzig Germany"}]}],"member":"311","published-online":{"date-parts":[[2022,11,24]]},"reference":[{"key":"e_1_2_8_1_1","unstructured":"\u00a0"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/nrm909"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/nrd4088"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/cbic.200800274"},{"key":"e_1_2_8_5_1","unstructured":"\u00a0"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1101\/gad.11.2.179"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.94.14.7239"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.beem.2010.09.003"},{"key":"e_1_2_8_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpeds.2010.12.042"},{"key":"e_1_2_8_10_2","first-page":"8757","volume":"63","author":"Kazansky A.
