Biological Activity

Description Trapidil (Rocornal, Trapymin, Avantrin, Trapymine) is a PDGF antagonist that can inhibit the proliferation of the PDGF-producing glioma cells.
Targets
PDGF [1]
In vitro
In vitro Trapidil interrupts the autocrine loop at the PDGF and PDGF-receptor level.Trapidil has proved to possess a significant antiproliferative activity[1]. The addition of 100 to 400 μg/ml trapidil significantly reduced cell proliferation induced by different growth factors (FCS, PDGF-BB, bFGF, EGF), the highest inhibitory effect being on PDGF-BB stimulated Mesangial cell(MC) growth. The effect of the drug was dose-dependent and seemingly specific. Trapidil is an anti-platelet drug active against various aggregating agents, such as collagen, ADP, arachidonic acid, PAF and calcium ionophore. It exerts its action by blocking the biosynthesis of thromboxane A2 and antagonizing its effect at the receptor level, and by stimulating the synthesis and release of prostacyclin[2]. Trapidil strongly inhibited osteoclast formation in co-cultures of bone marrow cells and osteoblasts without affecting receptor activator of NF-κB ligand (RANKL) or osteoprotegerin expression in osteoblasts. In addition, trapidil suppressed RANKL-induced osteoclast formation from osteoclast precursors. Trapidil reduced RANKL-induced expression of nuclear factor of activated T cells, cytoplasmic 1 (NFATc1), a master transcription factor for osteoclastogenesis, without affecting the expression of c-Fos that functions as a key upstream activator of NFATc1 during osteoclastogenesis. Trapidil has also been reported to inhibit phosphodiesterase, thromboxane A2, and CD40 signaling and activate protein kinase A[3].
Cell Research Cell lines Human Mesangial cell lines
Concentrations 100 μg/ml
Incubation Time 96 h
Method

Cell viability was determined by Trypan blue dye exclusion test and LDH assay. Supernatants, collected from cells seeded in serum-free medium and exposed to the different mitogens and drugs tested, were centrifuged and LDH concentration determined. Supernatants obtained from sonicated cells were used as a positive control. Furthermore, to definitely exclude a cytotoxic effect of Trapidil on human MC, cells incubated for four days with and without the drug were challenged with fresh medium containing 10% FBS, and cell proliferation evaluated.
In Vivo
In vivo Trapidil is an antiplatelet drug with specific platelet-derived growth factor antagonism and antiproliferative effects in the rat and rabbit models after balloon angioplasty[1]. Trapidil had a potent inhibitory effect on osteoclast formation and bone resorption induced by interleukin-1 in an animal model. No abnormal symptoms, such as changes in body weight, diarrhea, high fever, and convulsion, were observed after intraperitoneal injections of trapidil[3].

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.
