Target-Agnostic P-Glycoprotein Assessment Yields Strategies to Evade Efflux, Leading to a BRAF Inhibitor with Intracranial Efficacy.

J Am Chem Soc 2022 Jun 27. Epub 2022 Jun 27.

Department of Chemistry, University of Illinois at Urbana-Champaign, Urbana, Illinois 61801, United States.

The blood-brain barrier (BBB) presents a major hurdle in the development of central nervous system (CNS) active therapeutics, and expression of the P-glycoprotein (P-gp) efflux transporter at the blood-brain interface further impedes BBB penetrance of most small molecules. Designing efflux liabilities out of compounds can be laborious, and there is currently no generalizable approach to directly transform periphery-limited agents to ones active in the CNS. Here, we describe a target-agnostic, prospective assessment of P-gp efflux using diverse compounds. Read More

Targeting Cell Cycle Progression in HER2+ Breast Cancer: An Emerging Treatment Opportunity.

Int J Mol Sci 2022 Jun 11;23(12). Epub 2022 Jun 11.

Translational Oncology Laboratory, Avera Cancer Institute, Sioux Falls, SD 57105, USA.

The development of HER2-targeted therapies has dramatically improved patient survival and patient management and increased the quality of life in the HER2+ breast cancer patient population. Due to the activation of compensatory pathways, patients eventually suffer from resistance to HER2-directed therapies and develop a more aggressive disease phenotype. One of these mechanisms is the crosstalk between ER and HER2 signaling, especially the CDK4/6-Cyclin D-Rb signaling axis that is commonly active and has received attention for its potential role in regulating tumor progression.
