What is WO2010020675A1 (Google Patents) and what does “Example 74” refer to?
WO2010020675A1 is a published patent application that includes multiple worked examples. “Example 74” is one of those specific, numbered experimental or formulation examples inside the document. To answer what Example 74 does, which compound it describes, and how it relates to ribociclib, you need the exact text for Example 74 from the patent.
Because “Example 74” content is specific to the document version and the exact wording (and can span multiple pages/tables), the fastest way to verify the ribociclib connection is to open the document on Google Patents and copy the “Example 74” section text (or screenshots of the relevant pages).
If you paste the “Example 74” portion here, I can extract:
- the compound name/structure described there,
- the preparation or assay described,
- the intermediates/reagents used,
- and how (or whether) it maps to ribociclib.
How is ribociclib connected to this patent document?
Ribociclib is a specific CDK4/6 inhibitor drug. Patent examples that mention ribociclib or use similar core scaffolds usually fall into one of these buckets:
- an intermediate/precursor that is later used to make ribociclib,
- a related analog within the same chemical family (not necessarily ribociclib itself),
- a salt/formulation example that corresponds to ribociclib’s known forms,
- or a biological/compound screening example where ribociclib is used as a reference compound.
Whether Example 74 is directly “ribociclib” or “a compound used in the ribociclib synthesis/series” depends entirely on the exact wording in that example.
Can you confirm “Example 74” is actually about ribociclib?
Yes, but it requires text-level confirmation. On Google Patents, you can search within the page for:
- “ribociclib”
- “Example 74”
- chemical names that look like ribociclib (or its IUPAC name)
- or key motifs (e.g., the scaffold identifiers used in the application)
If you share the “Example 74” text, I can confirm whether it:
- explicitly names ribociclib,
- describes ribociclib’s synthesis steps,
- or describes a different compound in the same series.
Why would someone search this patent for ribociclib?
People typically search this way when they are trying to:
- trace synthesis routes from patents,
- identify early chemical claims covering ribociclib or close analogs,
- locate specific intermediates used in ribociclib manufacturing,
- or map a listed example to a compound named in later clinical/commercial records.
A patent number alone usually isn’t enough to know which drug is being targeted; the example text and claim language determine that.
What I need from you to give a precise answer
Paste one of the following:
- the exact text of “Example 74” from WO2010020675A1, or
- a link to the exact Google Patents page/section where Example 74 appears (plus the excerpt).
Then I’ll tell you exactly what Example 74 is, and whether it describes ribociclib (or an intermediate/analog used for it).
