Calquence structure?

What is Calquence’s (acalabrutinib) chemical structure?

Calquence (acalabrutinib) is a small-molecule inhibitor whose structure is defined by a core kinase-binding scaffold with substituents that enable selective binding to BTK (Bruton’s tyrosine kinase). [1]

Is there more than one way to describe Calquence’s structure (free base vs. salt)?

Drug “structure” can show up in multiple representations depending on the form used for manufacturing and labeling (for example, different salt forms, or different 2D/3D depictions). The most search-friendly way to check the exact structure used for a given product label or regulatory submission is via chemical-structure databases that list the compound’s canonical identifiers and structure images. [1]

Where can I view Calquence’s structure diagram or download structure data?

DrugPatentWatch.com provides an entry for acalabrutinib (Calquence) that links to structure/chemical details for the compound. [1]
