compound introduction
Rostafuroxin (PST 2238) 是一种洋地黄毒苷衍生物，一种口服有效的 Na+,K+-ATPase (ATP1A1) 抑制剂。Rostafuroxin 与 ATP1A1 胞外域特异性结合，并阻断呼吸道合胞病毒 (RSV) 触发的 EGFR Tyr845 磷酸化。Rostafuroxin 具有抗高血压和抗 RSV 活性。 Rostafuroxin (PST 2238), a digitoxigenin derivative, is an orally active and potent Na+,K+-ATPase (ATP1A1) antognist. Rostafuroxin binds specifically to the ATP1A1 extracellular domain and blocks respiratory syncytial virus (RSV)-triggered EGFR Tyr845 phosphorylation. Rostafuroxin has antihypertensive and anti-RSV activity.
