nifedipine

Nifedipine (Procardia) 是一种二氢吡啶类钙通道阻滞剂，可抑制细胞外钙离子跨膜流入心肌和血管平滑肌细胞，导致主要冠状动脉和全身动脉扩张，降低心肌收缩力。它常用于心肌功能不全的相关研究。

m-Nifedipine, an impurity of Nifedipine, serves as a potent calcium channel blocker and the preferred treatment option for cardiac insufficiencies.

Nifedipine HCl is a potent vasodilator agent with calcium antagonistic action. It is a useful anti-anginal agent that also lowers blood pressure.

Nifedipine D6 is deuterium labeled nifedipine which is a potent blocker of calcium channel.

Dehydro Nifedipine (BAY-b 4759) 是人血浆中硝苯地平的主要代谢物。Dehydro Nifedipine 抑制PC-12细胞葡萄糖摄取，IC50值为130 μM，硝苯地平是一种钙通道阻滞剂，用于治疗高血压和心绞痛。当硝苯地平被细胞色素P450 (CYP)异构体CYP3A4和CYP3A5代谢时形成脱氢硝苯地平。

Nitrendipine (BAY-E-5009) 是 Nifedipine 的类似物，是一种钙通道阻滞剂，具有显着的血管扩张作用。它是一种有效的抗高血压药且不会降低肾小球滤过率，并且具有轻微的利钠作用。

Nicardipine hydrochloride (YC-93 Hydrochloride) 是一种钙通道阻滞剂，IC50为 1 μM。它可阻断某些细胞壁中的钙离子并抑制冠状动脉和外周动脉的收缩，从而降低对氧气的需求心肌和减少动脉收缩和痉挛。它在临床上用作脑和冠状血管扩张剂。

AK-2-38 is a nifedipine analogue with potent smooth muscle calcium antagonist action and partial agonist effects on isolated guinea pig left atrium.

Nirudipine is a double (2-propoxyethyl) analogist of nifedipine and a calcium channel blocker, which is also a safe anti-angina Ca2+ antagonist with a broad range of efficacy for all types of angina. At the same time, Niludipine is a highly effective drug

5(6)-EET is a fully racemic version of the enantiomeric forms biosynthesized from arachidonic acid by cytochrome P450 enzymes. In solution, 5(6)-EET degrades into 5,6-DiHET and 5(6)-δ-lactone, which can be converted to 5(6)-DiHET and quantified by GC-MS. In neuroendocrine cells, such as the anterior pituitary and pancreatic islets, 5(6)-EET has been implicated in the mobilization of calcium and hormone secretion. 5(6)-EET is an inhibitor of T-type voltage-gated calcium channels (Cav3) that inhibits isoforms Cav3.1, Cav3.2 (IC50 = 0.54 μM), and Cav3.3 and decreases nifedipine-resistant phenylephrine-induced vasoconstriction in isolated mouse mesenteric arteries via Cav3.2 blockade when used at a concentration of 3 μM. In addition, it is a substrate of COX-1 and COX-2, as measured by oxygen consumption and product formation assays when used at a concentration of 50 μM. (±)5(6)-EET is provided as a mixture of the free acid and lactone.

FR-7534 is a calcium antagonist structurally similar to nifedipine.

5-O-Methylnaringenin is a marker, reduced MS detection of 5-O-methylnaringenin indicated that nifedipine may preferably remove a proton from the 5-position OH group in the A ring of the flavonoid skeleton.

6',7'-Dihydroxybergamottin(DHB), a well-known inhibitor of CYP3A4, the inhibition of CYP3A4 activity by DHB includes the inhibition of POR activity, DHB can inhibit nifedipine oxidation in a concentration-dependent manner.
