To control inflammation and analgesia, many marketed drugs are in practice but the majority of them have severe side effects. Methods: This study involved the synthesis of a pivalate-based Michael product and evaluated it for in vitro COX-1, COX-2, and 5-LOX inhibitory potentials using specific assays. Molecular docking studies were also assessed. Based on the in vitro results, the compound was also subjected to in vivo anti-inflammatory and antinociceptive studies. Results: The pivalate-based Michael product (MAK01) was synthesized by an organocatalytic asymmetric Michael addition of ethyl isobutyrate to N-phenylmaleimide with an isolated yield of 96%. The structure of the compound was confirmed through 1H and 13C NMR analyses. The observed IC50 values for COX-1, COX-2, and 5-LOX were 314, 130, and 105 \u03bcg\/mL, respectively. The molecular docking studies on the synthesized compound showed binding interactions with the minimized pockets of the respective enzymes. In a carrageenan model, a percent reduction in edema when administered at 10 mg\/kg (a reduction of 33.3 \u00b1 0.77% at the second hour), 20 mg\/kg (a reduction of 34.7 \u00b1 0.74% at the second hour), and 30 mg\/kg (a reduction of 40.58% \u00b1 0.84% after the fifth hour) was observed. The compound showed a significant response at concentrations of 50, 100, and 150 mg\/kg with latency times of 10.32 \u00b1 0.82, 12.16 \u00b1 0.51, and 12.93 \u00b1 0.45 s, respectively. Conclusion: In this study, we synthesized a pivalate-based Michael product for the first time. Moreover, based on its rationality and potency, it was found to be an effective future medicine for the management of analgesia and inflammation.<\/jats:p>","DOI":"10.3390\/ph17111522","type":"journal-article","created":{"date-parts":[[2024,11,12]],"date-time":"2024-11-12T05:21:59Z","timestamp":1731388919000},"page":"1522","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Synthesis and Anti-Inflammatory and Analgesic Potentials of Ethyl 2-(2,5-Dioxo-1-Phenylpyrrolidin-3-yl)-2-Methylpropanoate"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0154-7863","authenticated-orcid":false,"given":"Abdul","family":"Sadiq","sequence":"first","affiliation":[{"name":"Department of Pharmacy, Faculty of Biological Sciences, University of Malakand, Chakdara 18000, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-9841-9736","authenticated-orcid":false,"given":"Muhammad Arif","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Pharmacy, Faculty of Biological Sciences, University of Malakand, Chakdara 18000, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2560-9384","authenticated-orcid":false,"given":"Rehman","family":"Zafar","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Chemistry, Faculty of Pharmaceutical Sciences, Riphah International University, Islamabad 44000, Pakistan"},{"name":"Iqra Institute of Health Sciences, School of Pharmacy, Islamabad 44000, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Farhat","family":"Ullah","sequence":"additional","affiliation":[{"name":"Department of Pharmacy, Faculty of Biological Sciences, University of Malakand, Chakdara 18000, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sajjad","family":"Ahmad","sequence":"additional","affiliation":[{"name":"Department of Pharmacy, Faculty of Biological Sciences, University of Malakand, Chakdara 18000, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4299-2445","authenticated-orcid":false,"given":"Muhammad","family":"Ayaz","sequence":"additional","affiliation":[{"name":"Department of Pharmacy, Faculty of Biological Sciences, University of Malakand, Chakdara 18000, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"771","DOI":"10.1016\/j.cell.2010.03.006","article-title":"Inflammation 2010: New adventures of an old flame","volume":"140","author":"Medzhitov","year":"2010","journal-title":"Cell"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"495","DOI":"10.1080\/14737159.2023.2215928","article-title":"Blood-based biomarkers of chronic inflammation","volume":"23","author":"Pritzker","year":"2023","journal-title":"Expert Rev.
