Butenolide-Thiazolidinone Compounds as Agricultural Fungicide
Summary
The USPTO published patent application US20260109693A1 for butenolide compounds containing a thiazolidinone structure, filed on October 27, 2023 (Application No. 19114226). The five named inventors — Mingan Wang, Xili Liu, Yihao Li, Tingting Zhang, and Qian Zhang — disclosed compounds with general formula (I) characterised by a butenolide-thiazolidinone structure. The published application claims the compounds demonstrate fungicidal activity against agricultural pathogens and may protect crops, horticulture, and livestock from pathogen invasion.
About this source
USPTO classification C07D covers heterocyclic organic compounds: the chemical core of most small-molecule drugs, including kinase inhibitors, GLP-1 receptor agonists, antibiotics, antivirals, and CNS therapies. Every newly published application in C07D lands in this feed, around 160 a month. Applications publish 18 months after filing, so this feed reveals what medicinal chemistry groups at Pfizer, Novartis, Roche, Shionogi, and others were synthesizing in the prior year and a half. Watch this if you run a medicinal chemistry program, file patent clearance for new drug candidates, scout competitor pipelines before clinical readouts, or track heterocyclic innovation across therapeutic areas.
What changed
The USPTO published patent application US20260109693A1, a new chemical compound patent for butenolide-thiazolidinone structures classified under CPC C07D 417/06 and A01N 43/78 (agricultural chemicals). The application discloses preparation methods and use of the compounds as broad-spectrum agricultural fungicides effective against various crop pathogens.
Agrochemical companies and crop protection manufacturers should monitor this application, as the disclosed butenolide-thiazolidinone scaffold represents a potential new active ingredient class in the fungicide pipeline. Parties seeking to commercialise similar thiazolidinone-based agricultural chemicals may need to conduct freedom-to-operate analyses around the claimed structural formula (I).
