We previously reported that alkyl- or benzyl-substituted phosphonate esters with (S)-pyrethrolone blocked TcGLIP at nanomolar ranges, but the mechanism of enzyme\u2013substrate interactions remains elusive. Notably, it is unclear whether the conjugated diene of (S)-pyrethrolonyl moiety is essential for TcGLIP inhibition and whether such probes are effective in blocking pyrethrin biosynthesis for other pyrethrum plant species capable of cinerin I\/II and jasmolin I\/II biosynthesis but not pyrethrin I\/II. In this study, n-pentyl- or n-octyl-substituted phosphonate esters were synthesized with either (S)-cinerolone or (S)-jasmololone lacking the conjugated diene as mixtures of (S)p, (S)c and (R)p, (S)c diastereomers, then TcGLIP inhibition was evaluated. These compounds blocked TcGLIP in the order of (S)-pyrethrolonyl &amp;gt; (S)-cinerolonyl &amp;gt; (S)-jasmololonyl esters regardless of whether the alkyl chain moiety was n-pentyl or n-octyl. The (S)p, (S)c isomers were more potent inhibitors than the corresponding (R)p, (S)c isomers for the n-pentyl series compounds. In contrast, the inverse was the case for the n-octyl series compounds. These results contribute to understanding TcGLIP recognition mechanisms of the rethrolone alkyl chain and phosphorus atom and assist in probe design to influence pyrethrin biosynthesis in Asteraceae plants.<\/jats:p>","DOI":"10.1021\/acsomega.4c11003","type":"journal-article","created":{"date-parts":[[2025,5,9]],"date-time":"2025-05-09T13:17:17Z","timestamp":1746796637000},"page":"19436-19443","source":"Crossref","is-referenced-by-count":0,"title":["Synthesis and Structure\u2013Activity\nRelationship\nof Phosphonate Esters with (\n                    <i>S<\/i>\n                    )\u2011Cinerolone\nand (\n                    <i>S<\/i>\n                    )\u2011Jasmololone as Irreversible Inhibitors\nof the GDSL Esterase\/Lipase TcGLIP to Study Pyrethrin Biosynthesis"],"prefix":"10.1021","volume":"10","author":[{"given":"Takato","family":"Kurosawa","sequence":"first","affiliation":[{"name":"Kindai University , , 3327-204 Nakamachi , ,","place":["Nara, Japan, 631-8505"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noritada","family":"Matsuo","sequence":"additional","affiliation":[{"name":"Kindai University , , 3327-204 Nakamachi , ,","place":["Nara, Japan, 631-8505"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keisuke","family":"Takemoto","sequence":"additional","affiliation":[{"name":"Kindai University , , 3327-204 Nakamachi , ,","place":["Nara, Japan, 631-8505"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akari","family":"Murai","sequence":"additional","affiliation":[{"name":"Kindai University , , 3327-204 Nakamachi , ,","place":["Nara, Japan, 631-8505"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6403-0781","authenticated-orcid":true,"given":"Makoto","family":"Ihara","sequence":"additional","affiliation":[{"name":"Kindai University , , 3327-204 Nakamachi , ,","place":["Nara, Japan, 631-8505"]},{"name":"Kindai University , , 3327-204 Nakamachi , ,","place":["Nara, Japan, 631-8505"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3265-4343","authenticated-orcid":true,"given":"Yoo","family":"Tanabe","sequence":"additional","affiliation":[{"name":"Kwansei Gakuin University , , 1 Gakuen Uegahara, , ,","place":["Sanda, Hyogo, Japan, 669-1337"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1299-4570","authenticated-orcid":true,"given":"Kazuhiko","family":"Matsuda","sequence":"additional","affiliation":[{"name":"Kindai University , , 3327-204 Nakamachi , ,","place":["Nara, Japan, 631-8505"]},{"name":"Kindai University , , 3327-204 Nakamachi , ,","place":["Nara, Japan, 631-8505"]},{"name":"Kindai University , , ,","place":["Nara, Japan, 631-8505"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2025,5,9]]},"reference":[{"issue":"13","key":"2026081811190432000_cit1","doi-asserted-by":"publisher","first-page":"1529","DOI":"10.1016\/j.phytochem.2005.05.005","article-title":"Biosynthesis of pyrethrin I in seedlings\nof Chrysanthemum cinerariaefolium","volume":"66","author":"Matsuda","year":"2005","journal-title":"Phytochemistry"},{"issue":"2","key":"2026081811190432000_cit2","doi-asserted-by":"publisher","first-page":"183","DOI":"10.1111\/j.1365-313X.2012.04980.x","article-title":"Identification\nand characterization of a GDSL lipase-like protein that catalyzes\nthe ester-forming reaction for pyrethrin biosynthesis in Tanacetum\ncinerariifolium- a new target for plant protection","volume":"71","author":"Kikuta","year":"2012","journal-title":"Plant J."},{"issue":"3","key":"2026081811190432000_cit3","doi-asserted-by":"publisher","first-page":"934","DOI":"10.1104\/pp.19.00499","article-title":"Pyrethrin\nbiosynthesis: The cytochrome P450 oxidoreductase CYP82Q3 converts\njasmolone to pyrethrolone","volume":"181","author":"Li","year":"2019","journal-title":"Plant Physiol."},{"issue":"7","key":"2026081811190432000_cit4","doi-asserted-by":"publisher","first-page":"378","DOI":"10.2183\/pjab.95.027","article-title":"Discovery\nand development of pyrethroid insecticides","volume":"95","author":"Matsuo","year":"2019","journal-title":"Proc.
