AAA is an antagonist of G protein-coupled receptor 75 (GPR75).1It increases basal GPR75 protein levels and inhibits 20-HETE-induced reductions in GPR75 protein levels in PC3 cells. AAA (5 and 10 μM) also reduces 20-HETE-induced phosphorylation of EGFR, NF-κB, and Akt in, and cell migration of, PC3 cells.In vivo, AAA (10 mg/kg per day) reduces systolic blood pressure, albuminuria, renal angiotensin II levels, and cardiac hypertrophy in a Cyp1a1-Ren-2 transgenic rat model of malignant hypertension when administered prior to induction or after establishment of hypertension.2 1.Cárdenas, S., Colombero, C., Panelo, L., et al.GPR75 receptor mediates 20-HETE-signaling and metastatic features of androgen-insensitive prostate cancer cellsBiochim.

5-methyl-2-HOBA is an isoketal scavenger. It reduces angiotensin II-induced increases in systolic blood pressure in mice.

C2 Ceramide (d14:1 2:0) is a bioactive sphingolipid that, when administered dietarily at 100 μM, induces lipotoxic cardiomyopathy by increasing diastolic and systolic diameter, reducing fractional shortening, and decreasing the number of normal cardiac contractile events in Drosophila.

Quazinone is a selective inhibitor of phosphodiesterase 3 (PDE3) with positive inotropic and vasodilating properties. It induces relaxation of precontracted isolated human cavernous smooth muscle (IC50 = 4.2 μM), increases myocardial contractile force in anesthetized open-chest dogs in a dose-dependent manner (10-300 μg kg), decreases systolic and diastolic blood pressure, and inhibits DNA synthesis induced by the PDGF isoform PDGF-BB in bovine coronary artery smooth muscle cells in a concentration-dependent manner.

CXL-1020, a nitroxyl (HNO) prodrug, enhances cardiac inotropy lusitropy and Ca 2+ cycling in rats exhibiting abnormal relaxation, induces vasorelaxation, and augments cardiac function in canine models. It has been investigated for its potential in treating systolic and stable heart failure [1].

Lorundrostat (MT-4129) is an aldosterone synthase inhibitor with antihypertensive activity that lowers systolic blood pressure.

α-Angelica lactone has cardiotonic activity, may exert their effects by providing an increased contraction-dependent calcium pool to be released upon systolic depolarization.

18-Hydroxy-11-deoxy Corticosterone (18-OH-DOC) is a mineralocorticoid produced by the zona fasciculata of the adrenal gland, with its biosynthesis regulated by adrenocorticotropic hormone (ACTH) and angiotensin II. This regulation heightens 18-OH-DOC production in isolated human adrenal glomerulosa cells and allows for its formation from 11-deoxy corticosterone (DOC) in human SK-MEL188 melanoma cells. As an intermediate in progesterone metabolism, 18-OH-DOC can be converted to aldosterone in rat adrenal glands' capsular portion. Its continuous infusion (200 μg/rat per day) has been shown to raise systolic blood pressure in uninephrectomized saline-drinking rats, and elevated plasma levels of 18-OH-DOC have been observed in the adb/db mouse model of type 2 diabetes.

Serpinin, an agonist of the protease inhibitor Nexin-1 (PN-1), upregulates PN-1 expression via the cAMP-PKA-Sp1 signaling pathway, facilitating granule biogenesis in endocrine cells. It is employed in research on secretory function regulation [1]. Serpinin selectively targets β-adrenergic receptors, particularly interacting with β1-adrenergic receptors to activate the AC-cAMP-PKA pathway, thereby regulating myocardial systolic and diastolic function. Additionally, pGlu-serpinin upregulates Bcl2 mRNA transcription and provides neuroprotective effects [2].
