As ribociclib is mainly metabolized by the liver enzyme CYP3A4, inhibitors of this enzyme increase its concentrations in the body and could potentiate side effects and toxicity. Examples of such inhibitors include ketoconazole and similar antifungal drugs, ritonavir , clarithromycin , as well as grapefruit .
Enzyme Inhibitors Inducers; CYP1A1: Certain foods (e.g., cumin, turmeric) Certain herbs/herbal teas (e.g., peppermint, German chamomile, dandelion, Kava) Amiodarone ...
Another remaining question surrounding CDK inhibitors as a therapy is if certain cancers will evade or be resistant to treatment. One study showed that 20% of the patients being treated for metastatic ER+ HER2-breast cancer did not respond at all to treatment with a CDK4/6 inhibitor due to preexisting mutations allowing the cancer cells to continue proliferating despite treatment with the drug ...
Like the related drugs palbociclib and ribociclib, abemaciclib inhibits the enzymes cyclin-dependent kinase 4 (CDK4) and cyclin-dependent kinase 6 (CDK6). [8] These enzymes are responsible for phosphorylating and thus deactivating the retinoblastoma protein , which plays a role in cell cycle progression from the G1 ( first gap ) to the S ...

This is a chemical structure of Carfilzomib. A known proteasome inhibitor, now used in cancer treatment. We understand the main concept of proteasome inhibition, but there still is a variety of understand questions on how the inhibition will eventually lead to cell death. The m
A protein kinase inhibitor (PKI) is a type of enzyme inhibitor that blocks the action of one or more protein kinases. [1] Protein kinases are enzymes that phosphorylate (add a phosphate, or PO 4, group) to a protein and can modulate its function. [2] The phosphate groups are usually added to serine, threonine, or tyrosine amino acids on the ...
Lifileucel, sold under the brand name Amtagvi, is an adoptive T cell therapy used for the treatment of melanoma. [1] [2] [3]Specifically, lifileucel is a tumor-derived T cell immunotherapy composed of a recipient's own T cells.
