Piperlonguminine is an agent with anticancer, antihyperlipidemic, as well as anti-inflammatory properties.
Piperlonguminine is a bio-active isolate of Piper longum.
In vitro: In a previous study, piperlonguminine was discovered to inhibit melanin production in melanoma B16 cells stimulated with α-MSH, 3-isobutyl-1-methylxanthine or protoporphyrin IX, where piperlonguminine showed stronger depigmenting efficacy. However, piperlonguminine could not alter1-oleoyl-2-acetyl-sn-glycerol-induced melanogenesis and could not affect protein kinase C-mediated melanin production. In additioin, piperlonguminine was not able to inhibit the catalytic activity of cell-free tyrosinase from melanoma B16 cells, and such effect was attributed to the inhibitory action of piperlonguminine on α-MSH-induced signaling via cAMP to the cAMP responsive element binding protein [1].
In vivo: In vivo, rats were subjected to middle cerebral artery occlusion for 1h, followed by reperfusion for 23 h. The results showed that the intraperitoneal injection of piperlonguminine PE at 2.4 mg/kg was able to produce a significant neuroprotective potential in rats with cerebral ischemia. In addition, piperlonguminine could attenuate the neurological deficit scores, brain infarct volume and brain water content, and could inhibit the activation of NF-κB and MAPK [2].
Clinical trial: Up to now, piperlonguminine is still in the preclinical development stage.

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 saline, 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.
