Common Namedihydroouabain
DescriptionDihydroouabain is a cardenolide, a class of organic compounds known for their steroid-like structure and biological activity. It features a saturated lactone ring and acts primarily as an inhibitor of the Na+/K+-ATPase enzyme, which is crucial for maintaining cellular ion gradients. This inhibition leads to various physiological effects, including modulation of synaptic transmission, as demonstrated in chick brainstem slices (PMID:22100365 ). Dihydroouabain has been identified as a novel radiosensitizer for cervical cancer through high-throughput screening (PMID:32311597 ), marking it as a potential therapeutic agent. Additionally, it activates human RORγ/RORγT receptors, influencing immune responses by upregulating IL17A and IL17F in Th17 lymphocytes (PMID:29981919 ). It is also a substrate of the OATP1B3 transporter, which may affect its pharmacokinetics (PMID:24754247 ). Furthermore, dihydroouabain has been shown to potentiate NMDA currents in rat hippocampal neurons, implicating it in excitatory neurotransmission pathways (PMID:21521363 ). Overall, dihydroouabain's unique chemical structure and diverse biological interactions make it a significant compound in both pharmacology and biochemistry.
