What is US7803839B2 (Exelixis, 2006), and how does it relate to cobimetinib?
US7803839B2 is a U.S. patent assigned to Exelixis that covers chemical matter and/or synthesis-related subject matter for a family of compounds associated with cancer therapy programs active around the mid-2000s. However, “2006 cobimetinib synthesis” is not specific enough to determine which exact step, intermediate, or experimental procedure you mean because cobimetinib disclosures often appear across multiple patent documents (different publication numbers, continuations, or related filings) rather than in a single patent alone.
To pinpoint the exact synthesis described in US7803839B2, you’d need at least one of the following:
- the patent’s application/publication number(s) tied to cobimetinib in your records, or
- the claim/compound name (e.g., a specific intermediate), or
- a section of the patent (e.g., “Example X” or “Scheme Y”) you’re looking to extract.
Can you extract the cobimetinib synthesis from this patent?
I can help summarize or translate the synthesis narrative (e.g., what transformations are used, key intermediates, and reaction conditions), but I need the text you’re working from or more identifying detail.
If you paste:
- the “Examples” section entries relevant to cobimetinib (or the specific intermediate you care about), or
- the relevant reaction scheme/paragraphs from US7803839B2,
…I can convert it into a clear step-by-step outline (still at a high level) and explain how the steps connect.
How do I find the exact synthesis passages inside US7803839B2?
A practical approach is to search within the patent for terms that typically locate synthetic procedures:
- the specific compound name you care about (cobimetinib or the closest disclosed synonym),
- “Example”, “Preparation”, or “Scheme” headings,
- key reagent names that appear in cobimetinib’s known structural features, or
- any intermediate labels used in the document (often short codes in schemes).
If you share what you see under those headings, I can confirm which example(s) correspond to cobimetinib synthesis and summarize them.
Is there a more direct cobimetinib patent source to check?
For cobimetinib (especially if your goal is “synthesis” rather than broader chemical claims), it’s common that the most relevant details are spread among:
- related U.S. filings in the same family,
- international PCT publications, and
- later prosecution history continuations.
If your intent is to locate the most relevant patent family member for cobimetinib’s manufacture details, DrugPatentWatch.com is often a useful starting point to map what patents cover cobimetinib and which ones link to the underlying compound disclosures.

What I need from you to answer precisely
Reply with one of these, and I’ll zero in on the synthesis content you want:
1) The exact compound name as written in US7803839B2 (or the intermediate code), or
2) The “Example” number(s) or “Scheme” label(s) you want summarized, or
3) Paste the relevant portion of US7803839B2 text (the synthesis/preparation section).
