Chemical Properties
| Description | Latrunculin B, an alkaloid from the Red Sea sponge, is an actin polymerization inhibitor with antifungal and antiprotozoal activity.Latrunculin B modulates the electrophysiological characteristics of the pulmonary veins and attenuates the occurrence of torsade de pointes, and may be used in the study of glaucoma in adolescents. |
| Targets&IC50 | HeLa cells:1.4 μM |
| In vitro | Displaying growth inhibition of HeLa cells with an IC50 value of 1.4 μM, Latrunculin B also modulates electrophysiological characteristics and arrhythmogenesis in pulmonary vein cardiomyocytes[1]. In pulmonary vein (PV) preparations, Latrunculin B (100 nM) decreases spontaneous electrical activity by 16±4%. Moreover, it reduces the late Na+ current, L-type Ca2+ current, Na+/Ca2+ exchanger current, and stretch-activated BKCa current in PV cardiomyocytes. Latrunculin B alters the transient outward K+ current and ultra-rapid delayed rectifier K+ current, while increasing the delayed rectifier K+ current in isolated PV cardiomyocytes. Additionally, at a concentration of 100 nM, Latrunculin B decreases intracellular Ca2+ transient and sarcoplasmic reticulum Ca2+ content in PV cardiomyocytes, attenuating stretch-induced increased spontaneous electrical activity and trigger activity[2]. |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . A total of 10 animals were administered, and the formula you used is 5% 
DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.Preparation method for in vivo formula: Take 50 μL DMSO main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O mix well and clarify
main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O mix well and clarifyFor Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
