Application

LDN193189 hydrochloride has been used as an ALK2/3 (type I receptor serine-threonine kinases) inhibitor, to study the effect of TGFβ1/2/3 (tumor growth factor β) and BMP (bone morphogenetic protein) signaling on spinal cord development in zebrafish. It has also been used to inhibit SMAD (homologues of the Drosophila protein, mothers against decapentaplegic), in order to prevent non neuronal differentiation.

Biochem/physiol Actions

LDN193189 is a derivative of dorsomorphin that is a highly selective antagonist of BMP receptor isotypes ALK2 and ALK3 (IC50 of: 5 and 30 nM). The selectivity of LDN193189 for ALK2/3 is 200 fold over the TGF-B type receptors ALK4,-5 and -7. In murine smooth muscle cells, the compound inhibits BMP-4 induced phosphorylation of SMAD 1/5/8 with an IC50 of 5 nM.
LDN193189 is a selective BMP receptor antagonist.
Although LDN193189 is a structural analog of dorsomorphin, these two drugs are found to establish different cellular responses. In vitro analysis reveals that LDN193189 inhibits a number of intracellular kinases such as, mitogen activated protein kinase 14 and 8 ( p38and c-Jun N-terminal kinase respectively), as well as those associated with AKT (serine/threonine kinase) and mTOR (mammalian target of rapamycin) signaling mechanisms. LDN193189 is known to elevate the levels hemoglobin and thus helps to prevent the onset of anemia of inflammation.

Preparation Note

The product is water soluble at a minimum of 5 mg/mL.

Preguntas

  1. How to interpret water content and salt content values in CoA? They are given in mols and they are huge! I need to make 5mM solution of LDN 193189, how should I take into account these values?

    1 respuesta

    1. The Certificate of Analysis (CoA) for LDN193189 hydrochloride, lot 0000362892 provides the information regarding water (4 mol) and salt (3.1 mol) content.

      These values are expressed in moles per mole of the compound. This means that for every mole of the compound, there are 4 moles of water and 3.1 moles of salt (likely HCl, as the compound is a hydrochloride salt). These values indicate the degree of hydration and the amount of hydrochloride associated with the compound, which is important for calculating the exact molecular weight to prepare an accurate solution.

      The molecular weight of the free base is provided as 406.48 g/mol. Add the contributions of water (18.015 g/mol per mole) and HCl (36.46 g/mol per mole):
      Adjusted Molecular Weight = 406.48 + ( 4 × 18.015) + (3.1 × 36.46)
      Calculate this value to get the total molecular weight.
      With the adjusted MW, you can prepare your desired solutions.
