Liguzinediol
Liguzinediol is a Bcl-2 upregulator that exerts cardioprotective effects by upregulating Bcl-2, downregulating Bax and cleaved caspase-3, and inhibiting myocardial apoptosis, RAAS, oxidative stress, inflammation, and extracellular matrix remodeling. Liguzinediol can be used for research on heart failure and cardiac fibrosis.

体外実験
Liguzinediol (10 μM) inhibits Ang II-stimulated cardiac fibroblast proliferation, ameliorates Ang II-stimulated morphological changes in cardiac fibroblasts, and reduces the ratio of type I/III collagen in Ang II-stimulated cardiac fibroblasts[2].
Liguzinediol (10 μM) downregulates MMP-2 and MMP-9 expression and upregulates TIMP-1 expression in Ang II-stimulated cardiac fibroblasts[2].
Liguzinediol (1-100 μM) produces a positive inotropic effect in isolated rat hearts without causing chronotropic changes[5].
Liguzinediol (100 μM) has no effect on the action potential duration of rat papillary muscle and left ventricular myocytes[5].
The positive inotropic effect of Liguzinediol (100 μM) is not mediated by β-AR, PDE, Na+-K+ ATPase, α1-AR, dopamine D1 receptor, or Na+-Ca2+ exchanger in isolated rat hearts[5].
Liguzinediol (100 μM) increases Ca2+ transients in rat left ventricular cardiomyocytes and restores caffeine-induced SR Ca2+ depletion[5].
Liguzinediol (100 μM) does not increase L-type Ca2+ channel current in rat left ventricular myocytes[5].
The positive inotropic effect of Liguzinediol (100 μM) is mediated by ryanodine receptor-dependent Ca2+ release in isolated rat hearts[5].
The positive inotropic effect of liguzinediol (100 μM) is mediated through SERCA2a-dependent Ca2+ handling in isolated rat hearts[5].
Liguzinediol (100 μM; 30 min) inhibits the activities of PP1 and PP2A in rat left ventricular tissue extracts, reducing PP1 activity to 86.0% of the control level and PP2A activity to 88.8% of the control level[6].
Liguzinediol (1-100 μM; 30 min) increases phosphorylation at PLB Ser-16 and Thr-17 sites in isolated rat ventricular myocytes in a concentration-dependent manner, reaching maximum ratios of 0.85 (p-PLB Ser-16/total PLB) and 0.35 (p-PLB Thr-17/total PLB) at 100 μM, respectively[6].

Parmacokinetics
体内実験
Liguzinediol (5-20 mg/kg; i.g.; once daily; two weeks) exerts protective effects against DOX-induced cardiac fibrosis in rats by reducing hydroxyproline content, decreasing the ratio of collagen type I/III, downregulating MMP-2 and MMP-9, and upregulating TIMP-1[2].
Liguzinediol (5-20 mg/kg; p.o.; daily; 8 weeks) alleviates myocardial infarction-induced heart failure in rats, and its protective effect is associated with the regulation of the TGF-β1/Smads pathway[3].
Liguzinediol (1-100 μM; retrograde coronary perfusion) produces a dose-dependent positive inotropic effect in isolated rat hearts, increasing LVDP to 187 mm Hg at 100 μM without changing heart rate[5].
Liguzinediol (20 mg/kg; intravenous injection; single administration) significantly increases left ventricular contractility in healthy male Sprague Dawley rats[6].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
