(S)-Carvedilol 是 Carvedilol 的 S 型异构体，是一种非选择性 β/α-1 受体阻断剂。(S)-Carvedilol 可以抵抗 Doxorubicin (DOX) 的血管或心脏毒性。
(S)-Carvedilol, the S-enantiomer of Carvedilol, is a non-selective β/α-1 blocker. (S)-Carvedilol exerts protection against the vascular or cardiac toxicity of Doxorubicin (DOX)[1].
The β-receptor blocking activity of (S)-Carvedilol is about 100 times greater than that of (R)-Carvedilol, whereas both enantiomers show equipotent potency as α-blockers[1].(S)-Carvedilol significantly attenuates Doxorubicin (DOX)-induced cell death, apoptotic morphological changes, decrease the mitochondrial membrane potential and oxidative stress responses by increasing the superoxide dismutase and catalase activities, and decreasing malondialdehyde contents and reactive oxygen species levels via the PI3K/AKT/eNO synthase pathway in vitro[1].(S)-Carvedilol treatment significantly upregulates the expression levels of p-eNOS in HUVECs[1].
