If you’re looking for US patent applications on Google Patents about vinblastine and vindoline biosynthesis, here’s how to find them and what to expect.
How to search on Google Patents
- Go to patents.google.com
- In the search box, try queries such as:
- "vindoline biosynthesis vinblastine US"
- "vinblastine vindoline biosynthesis US patent"
- "Catharanthus roseus vinblastine biosynthesis US"
- UseFilters:
- Document type: Patent
- Country: United States
- Publication type: Patent Application (A1, A2, etc.)
- Look for titles that mention biosynthesis, production, or pathways for vinblastine, vindoline, vindoline/vinblastine production, or TIAs (monoterpenoid indole alkaloids).
- Open a result and check:
- Publication number (e.g., US A1)
- Assignee / inventors
- Abstract for a quick gist
- Claims section to see what is actually claimed (e.g., engineered pathways, host organisms, specific enzymes)
- Legal status or family members for whether it’s granted or pending
Tips on what to look for
- The term “biosynthesis” or “production” or “pathway reconstruction” in the title or abstract.
- Host systems mentioned (plants, yeast, bacteria, other microbes, cell-free systems).
- Enzymes or steps involved (e.g., upstream TIAs pathway steps, vindoline-specific steps like vindoline formation, or the coupling/dimerization step forming vinblastine).
- Assignee (universities, biotech companies, or agrochemical firms) to gauge whether it’s academic or commercial.
If you want, you can share a link or publication number (e.g., US A1 publication number) and I’ll summarize the patent’s scope, main claims, and how the biosynthesis approach is proposed.
Note on biosynthesis context
- Vinblastine and vindoline are monoterpenoid indole alkaloids produced in Catharanthus roseus (periwinkle). Patents in this space often cover:
- Reconstruction of parts of the biosynthetic pathway in heterologous hosts (yeast, bacteria, plant cells)
- Expression of specific enzymes to produce precursor molecules or to complete the vindoline/vinblastine biosynthesis
- Methods for scalable production, extraction, or purification
- Improvements to flux, yield, or enzyme efficiency
If you’d like, tell me a specific US publication number or paste a link and I’ll pull out the key claims and provide a concise summary.
