Arachidonic acid (Immunocytophyt) is a polyunsaturated omega-6 essential fatty acid that serves as a major component of biological membranes and animal phospholipids. It is synthesized from dietary linoleic acid and acts as a precursor to lipid mediators such as prostaglandins, thromboxanes, and leukotrienes. Arachidonic acid can improve cognitive responses and cardiovascular function and is commonly used to induce paw edema models.

Temocapril is an inhibitor of tyrosine kinase.

NS3623 is an activator of human ether-a-go-go-related gene (hERG) potassium channels with a dual mode of action, also acting as an inhibitor of hERG1 channels. It activates the IKr and Ito currents and exhibits an antiarrhythmic effect.

P-1075 opens mitochondrial K(ATP) channels and generates reactive oxygen species causing cardioprotection of rabbit hearts. P-1075 is an effective activator of sulfonylurea receptor 2-associated ATP-sensitive potassium channels (SUR2-KIR6) (EC50: 45 nM fo

DCPIB, a known specific and potent inhibitor of volume-regulated anion channels (VRAC),DCPIB displayed superior selectivity toward TRESK with an IC50 of 0.14 μM, demonstrating at least 100-fold higher affinity over TREK1/TRAAK channels.

Squalane is a lipid found in some fish oils (especially shark liver oil) and some vegetable oils. It has anticancer and antioxidant properties and is used as a skin moisturizer and emollient.

Cardiogenol C is a cardiomyogenesis inducer in embryonic stem cells.

Temocapril hydrochloride (CS-622 HCl), the hydrochloride of Temocapril, is a long-acting ACE inhibitor used for the therapy of hypertension.

L-α-lysophosphatidylinositol sodium is an endogenous ligand of GPR55 and an endogenous cannabinoid neurotransmitter that is involved in controlling cell survival and tumor progression.

Cardiogenol C hydrochloride (Cardiogenol C) can induces the differentiation of ESCs into cardiomyocytes (EC50= 100 nM).

AZD 7009 is a novel antiarrhythmic compound that inhibits the sodium current of hNav1.5 in CHO K1 cells with an IC50 of 11 uM. AZD 7009 inhibited late sodium current in isolated rabbit atrial and ventricular myocytes, and prolonged E-4031-induced action potential duration, promoting early post-depolarization of Purkinye fibers (EADs).

Oxodipine, a dihydropyridine-type calcium antagonist, inhibited KCl-induced aortic contraction in rabbits and reduced cardiac force in less potent rat ventricular test-paper contractions. In rat cultured neonatal ventricular myocytes, Oxodipine reduced L-type Ca currents (I) with an IC of 0.24 μM, and against T-type Ca currents (I) with an IC of 0.41 μM. Oxodipine causes constipation in mice and gingival hyperplasia in dogs.

Amiodarone hydrochloride is an anti-anginal agent and a class III antiarrhythmic drug that inhibits potassium channels (including wild-type hERG channels and their tail currents, with an IC₅₀ of approximately 45 nM) as well as voltage-gated sodium channels. This leads to prolonged action potential duration in ventricular and atrial myocytes, resulting in reduced heart rate and vascular resistance. It activates ERK1/2 and p38 MAPK signaling pathways in fibroblasts, promoting cell proliferation and myofibroblast differentiation. Amiodarone hydrochloride is widely used in the study of supraventricular and ventricular arrhythmias and can also be used to establish pulmonary fibrosis animal models.

Levosimendan (OR1259) is a calcium sensitizer used in the management of acutely decompensated congestive heart failure. It increases the sensitivity of the heart to calcium, thus increasing cardiac contractility without a rise in intracellular calcium. Levosimendan exerts its effect by increasing calcium sensitivity of myocytes by binding to cardiac troponin C in a calcium-dependent manner.

Reverse T3 (3,3',5'-triiodo-L-thyronine) inhibits the increase of sodium current generated by other thyroid hormone analogs in neonatal rat myocytes.

Murrayafoline A is a natural carbazole alkaloid found primarily in plants of the genera Murraya and Glycosmis. Murrayafoline A directly targets Specific Protein 1 (Sp1), thereby inhibiting the NF-κB and MAPK signaling pathways. Murrayafoline A attenuates the Wnt/β-catenin pathway by promoting the degradation of intracellular β-catenin. Murrayafoline A induces G0/G1 phase arrest in platelet-derived growth factor (PDGF)-stimulated vascular smooth muscle cells. Murrayafoline A enhances contractility and L-type calcium currents in rat ventricular myocytes by activating protein kinase C. Murrayafoline A inhibits LPS-induced neuroinflammation in vivo. Murrayafoline A can be used in research on inflammation, vascular complications, and colorectal cancer.

SBI-477 is a chemical probe that stimulates insulin signaling by deactivating the transcription factor MondoA. It coordinately inhibits triacylglyceride (TAG) synthesis and enhances basal glucose uptake in human skeletal myocytes.

SIRT3 Activator 1 (Compound 5v) is a selective activator of SIRT3. It enhances the expression of SIRT3, leading to upregulation of SOD2 and OPA1. This activity effectively mitigates mitochondrial dysfunction, alleviates oxidative stress, and maintains the vitality of cardiac myocytes. SIRT3 Activator 1 is useful in the study of cardiovascular diseases.

GP-515 HCl is an adenosine kinase inhibitor. In cultured rat myocardial myocytes (RMMs), GP-515 can induce the expression of vascular endothelial growth factor (VEGF). Under severe hypoxia (1% O(2)), GP-515 (20 microM) does not affect VEGF protein expression, but under mild hypoxic conditions, it increases VEGF expression by 27%.

5-Hydroxypropafenone, an active metabolite of propafenone, inhibits transient outward potassium current (Ito) in isolated human atrial myocytes with an IC50 of 1.5 µM. In vivo, it increases the atrial effective refractory period in dogs at doses of 0.5, 1, and 2 mg/kg.
