(S)-(-)-Felodipine-d5 是 (S)-(-)-Felodipine 的氘代物。(S)-(-)-Felodipine 是 Felodipine 的异构体。Felodipine 是一种二氢吡啶，是一种有效的血管选择性钙通道 (b>calcium channel) 拮抗剂。Felodipine 通过选择性作用于血管平滑肌，尤其是阻力血管来降低血压。Felodipine 是具有抗高血压活性，可诱导自噬。Felodipine 可以跨越血脑屏障。
(S)-(-)-Felodipine-d5 is the deuterium labeled (S)-(-)-Felodipine. (S)-(-)-Felodipine is the S enantiomer of Felodipine. Felodipine, a dihydropyridine, is a potent, vasoselective calcium channel antagonist. Felodipine lowers blood pressure (BP) by selective action on vascular smooth muscle, especially in the resistance vessels. Felodipine, an anti-hypertensive agent, induces autophagy. Felodipine can cross the blood-brain barrier[1][2][3].
Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs[1].
