Talk:Palbociclib

Need to clarify the HER2-negative
Is approval only for ER+ if patient/tumour also HER2-negative ? - Rod57 (talk) 04:22, 30 December 2015 (UTC)

What next - PALOMA-2 - EU
When is PALOMA-2 due to report data ? Is it needed for an EU application ? When is an EU application expected ? - Rod57 (talk) 18:02, 30 December 2015 (UTC)

History - Chemistry
How was this molecule found ? Is it a derivative or analogue of a natural molecule ? - Rod57 (talk) 19:17, 30 December 2015 (UTC) To partially answer your question, a sustained medicinal chemistry effort was made to identify selective Cdk4/6 inhibitors. A description of the work conducted over many years can be found in the following references: https://pubs.acs.org/doi/abs/10.1021/jm049355%2B Pyrido[2,3-d]pyrimidin-7-ones as Specific Inhibitors of Cyclin-Dependent Kinase 4, Scott N.

Continued synthetic work prepared and identified PD 0332991 which would later be named Palbociclib, the Cdk4-inhibiting component in (IBRANCE®, Pfizer Inc.). Structural similarity of the earlier leads to PD 0332991 can be seen: https://pubs.acs.org/doi/10.1021/jm049354h Discovery of a Potent and Selective Inhibitor of Cyclin-Dependent Kinase 4/6, Peter L.

How is it administered
How is it administered (oral?, IV?, SC?). How often ? - Rod57 (talk) 17:36, 25 November 2016 (UTC)

Theory/motivation
Why is it added to other therapies ? Is it to kill cancer cells, avoid resistance, or reduce side-effects ? - Rod57 (talk) 17:40, 25 November 2016 (UTC)
