| Targets |
Calcium Channel antagonist 3 targets voltage-gated calcium channels (VGCCs), particularly L-type or T-type subtypes, which are involved in calcium influx in excitable cells. These channels are critical for numerous physiological processes including cardiac and smooth muscle contraction, neurotransmitter release, and neuronal excitability. By inhibiting these channels, the compound reduces calcium-dependent signaling pathways. The compound's IC50 of 5-20 µM indicates moderate potency against the target channels.

|---|---|
| ln Vitro |
In vitro, Calcium Channel antagonist 3 demonstrates inhibitory activity against voltage-gated calcium channels with an IC50 of 5-20 µM. The compound's activity is typically assessed in cell-based assays measuring calcium influx using fluorescent indicators or electrophysiological recordings. The compound shows concentration-dependent inhibition of calcium currents. It is used in neurophysiological and cardiovascular research to investigate calcium channel function. The compound has a purity of 99.98% and is soluble in DMSO at 60 mg/mL.
|
| ln Vivo |
In vivo studies of Calcium Channel antagonist 3 are conducted in animal models of hypertension, arrhythmias, and neuropathic pain. In hypertension models, blood pressure reduction is measured following compound administration. In arrhythmia models, ECG is recorded to assess antiarrhythmic effects. In neuropathic pain models, mechanical allodynia and thermal hyperalgesia are assessed using von Frey filaments and hot plate tests. The compound is typically administered via intraperitoneal or intravenous injection. Dosing regimens vary depending on the specific model and desired exposure levels. The compound's in vivo efficacy is dose-dependent.
|
| Enzyme Assay |
For non-cell-based receptor binding assays, Calcium Channel antagonist 3 can be evaluated using membrane preparations from tissues or cells expressing voltage-gated calcium channels. Radioligand binding displacement experiments are performed using a suitable radiolabeled calcium channel ligand such as [3H]-nitrendipine for L-type channels. Membrane homogenates are incubated with increasing concentrations of the test compound and a fixed concentration of the radioligand at room temperature for 1-2 hours. Bound radioligand is separated from free by rapid filtration through GF/B filters. Nonspecific binding is determined in the presence of excess unlabeled ligand. IC50 values are calculated from displacement curves using nonlinear regression analysis.
|
| Cell Assay |
For in vitro cellular assays, cells expressing voltage-gated calcium channels are cultured in appropriate media and plated in multi-well plates. Cells are loaded with a calcium-sensitive fluorescent dye such as Fluo-4 AM. After dye loading and washing, cells are pre-incubated with various concentrations of Calcium Channel antagonist 3 for 15-30 minutes. Calcium influx is stimulated by the addition of a depolarizing agent such as high potassium buffer. Fluorescence intensity is measured using a fluorescence plate reader. The reduction in calcium signal compared to control wells is used to calculate the IC50 value. Patch-clamp electrophysiology can also be employed for direct measurement of channel current inhibition.
|
| Animal Protocol |
For in vivo animal studies, Calcium Channel antagonist 3 is typically administered to rodents via intraperitoneal or intravenous injection. The compound is first dissolved in DMSO, then diluted with appropriate vehicles. In neuropathic pain models (e.g., spinal nerve ligation or chemotherapy-induced neuropathy), mechanical allodynia and thermal hyperalgesia are assessed. In hypertension models (e.g., spontaneously hypertensive rats), blood pressure is monitored via tail-cuff or telemetry. In arrhythmia models, ECG parameters including QT interval and arrhythmia incidence are evaluated. Dosing regimens vary depending on the specific model.
|
| ADME/Pharmacokinetics |
The pharmacokinetic properties of Calcium Channel antagonist 3 have not been extensively characterized in the published literature. Based on its physicochemical properties (molecular weight of 426.53), the compound is expected to have moderate lipophilicity. The compound is soluble in DMSO at 60 mg/mL and can be formulated for both in vitro and in vivo administration. For in vivo studies, the compound is typically administered via injection. The compound should be stored at -20°C for long-term stability. Comprehensive ADME studies would be needed for full pharmacokinetic characterization.
|
| Toxicity/Toxicokinetics |
The toxicity profile of Calcium Channel antagonist 3 has not been extensively reported. As a research compound used primarily for in vitro and preclinical in vivo studies, comprehensive toxicological evaluation would include assessment of acute toxicity, sub-chronic toxicity, genotoxicity, and cardiotoxicity. Given its mechanism as a calcium channel inhibitor, potential off-target effects on cardiovascular function would be a primary concern. The compound is for research use only and not for human consumption. Standard safety pharmacology studies would include cardiovascular, respiratory, and central nervous system assessments.
