Biological Activity

Description Lacidipine (GX-1048, GR-43659X, SN-305) is a L-type calcium channel blocker, used for treating high blood pressure.
L-type calcium channel [1]
In vitro

Lacidipine, an L-type Ca(2+) channel blocker that also inhibits [Ca(2+)](ER) efflux, enhances folding, trafficking, and activity of degradation-prone glucocerebrosidase (GC) variants. Lacidipine remodels mutated GC proteostasis by simultaneously activating a series of distinct molecular mechanisms, namely modulation of Ca(2+) homeostasis, upregulation of the ER chaperone BiP, and moderate induction of the unfolded protein response. [1] Lacidipine almost completely inhibits cholesterol esterification in cholesterol loaded mouse cultured peritoneal macrophages. [2]

In vivo Lacidipine has non-significant effects on blood pressure but inhibits the paradoxical increases in plasma renin activity (PRA) and in renin mRNA in kidney that are found in salt-loaded stroke-prone spontaneously hypertensive rats (SHRSP). Lacidipine restores the physiological downregulation of renin production by high salt and reduces left ventricular hypertrophy and mRNA levels of atrial natriuretic factor and transforming growth factor-beta1. [3] Lacidipine (1 and 3 mg/kg) also effectively increases calcium concentrations significantly in ovariectomized rats. [4] Lacidipine, a dihydropyridine-type calcium antagonist, reduces the cardiac hypertrophy and the cardiacendothelin-1 (ET-1) gene overexpression occurring in salt-loaded stroke-prone spontaneously hypertensive rats (SL-SHRSP), an effect occurring without systolic blood pressure (SBP) change. Lacidipine exerts a dose-related inhibition of ventricle hypertrophy and preproET-1-mRNA expression in SHRSP and indicate that this effect is unrelated to SBP changes. [5]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
