Here, we used multiple mass-spectrometry-based approaches to identify catechol-O-methyltransferase (COMT) as a major binding target of celastrol and characterized their interaction comprehensively. Celastrol was found to inhibit the enzymatic activity of COMT and increased the dopamine level in neuroendocrine chromaffin cells significantly. Our study not only revealed a novel binding target of celastrol but also provided a new scaffold and cysteine hot spot for developing new generation COMT inhibitors in combating neurological disorders.<\/jats:p>","DOI":"10.1021\/acschembio.2c00011","type":"journal-article","created":{"date-parts":[[2022,3,18]],"date-time":"2022-03-18T14:51:05Z","timestamp":1647615065000},"page":"2003-2009","source":"Crossref","is-referenced-by-count":8,"title":["Integrated Mass Spectrometry Reveals Celastrol As\na Novel Catechol-O-methyltransferase Inhibitor"],"prefix":"10.1021","volume":"17","author":[{"given":"Haijun","family":"Guo","sequence":"first","affiliation":[{"name":"The Hong Kong Polytechnic University , , ,","place":["Hong Kong, SAR, China, 999077"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Yang","sequence":"additional","affiliation":[{"name":"The Hong Kong Polytechnic University , , ,","place":["Hong Kong, SAR, China, 999077"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qi","family":"Zhang","sequence":"additional","affiliation":[{"name":"The Hong Kong Polytechnic University , , ,","place":["Hong Kong, SAR, China, 999077"]},{"name":"Centre for Eye and Vision Research , 17W Hong Kong Science Park , ,","place":["Hong Kong, SAR, China, 999077"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie-Ren","family":"Deng","sequence":"additional","affiliation":[{"name":"The Hong Kong Polytechnic University , , ,","place":["Hong Kong, SAR, China, 999077"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Yang","sequence":"additional","affiliation":[{"name":"The Hong Kong Polytechnic University , , ,","place":["Hong Kong, SAR, China, 999077"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuqi","family":"Li","sequence":"additional","affiliation":[{"name":"The Hong Kong Polytechnic University , , ,","place":["Hong Kong, SAR, China, 999077"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pui-Kin","family":"So","sequence":"additional","affiliation":[{"name":"The Hong Kong Polytechnic University , , ,","place":["Hong Kong, SAR, China, 999077"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3511-5620","authenticated-orcid":true,"given":"Thomas C.","family":"Lam","sequence":"additional","affiliation":[{"name":"Centre for Eye and Vision Research , 17W Hong Kong Science Park , ,","place":["Hong Kong, SAR, China, 999077"]},{"name":"The Hong Kong Polytechnic University , , ,","place":["Hong Kong, SAR, China, 999077"]},{"name":"The Hong Kong Polytechnic University , , ,","place":["Hong Kong, SAR, China, 999077"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Man-kin","family":"Wong","sequence":"additional","affiliation":[{"name":"The Hong Kong Polytechnic University , , ,","place":["Hong Kong, SAR, China, 999077"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2244-6516","authenticated-orcid":true,"given":"Qian","family":"Zhao","sequence":"additional","affiliation":[{"name":"The Hong Kong Polytechnic University , , ,","place":["Hong Kong, SAR, China, 999077"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2022,3,18]]},"reference":[{"issue":"3","key":"2026081413070628600_cit1","doi-asserted-by":"publisher","first-page":"770","DOI":"10.1021\/acs.jnatprod.9b01285","article-title":"Natural products as sources of new drugs over the nearly\nfour decades from 01\/1981 to 09\/2019","volume":"83","author":"Newman","year":"2020","journal-title":"J.
