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.

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].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
