Biological Activity for LDN 193189 dihydrochloride

LDN 193189 dihydrochloride is a potent and selective ALK2 and ALK3 inhibitor (IC50 values are 5 and 30 nM, respectively); inhibits BMP4-mediated Smad1/5/8 activation. Exhibits >200-fold selectivity for BMP signaling over TGF-β signaling. Also exhibits selectivity over AMPK, PDGFR and MAPK signaling. Promotes neural induction of hPSCs in combination with SB 431542 (Cat.No. 1614). Also induces differentiation of hPSCs into nociceptive sensory neurons in combination with SB 431542 (Cat.No. 1614), SU 5402 (Cat.No.3300), CHIR 99021 (Cat.No. 4423) and DAPT (Cat.No. 2634).

LDN 193189 synthesized to cGMP guidelines also available.

Scientific Data

Application of LDN 193189 in motor neurons differentiated from iPSCs Image shows IBJ6 human fibroblast induced pluripotent stem cells which have been differentiated into motor neurons. This was performed using a combination of LDN 193189 (100 nM) and SB 431542 (Catalog # 1614, Tocris) followed by Retinoic acid (Catalog # 0695, Tocris) and Purmorphamine (Catalog # 4551, Tocris) culture on Laminin for 18 days. Commitment to the motor neuron fate was assessed using the motor neuron marker anti-Human Islet-1 (red, R&D Systems®, Catalog # AF1837) and the general neuronal marker, beta III tubulin (green, R&D Systems®, Catalog # MAB1195). For visualization, the neurons were stained using Northernlights™ 557-conjugated Donkey anti-Goat Secondary Antibody (R&D Systems®, Catalog # NL001) and Northernlights™ 493-conjugated Donkey anti-Mouse Secondary Antibody (R&D Systems®, Catalog # NL009 NL009) and counterstained with DAPI (blue, Catalog # 5748, Tocris).

Efficient and effective inhibitor of BMP-like receptors.
By Paul Humphreys on 12/11/2020
Assay Type: In Vitro
Species: Human
Cell Line/Tissue: TC28a2

To perform inhibition of BMP-like receptors during various interrogations. Performed blanket inhibition of BMP-like receptor kinase activity with 50nM (working) and selective inhibition of ALK3/BMPR1A with 5nM (working) leaving ALK6/BMPR1B active. Non-toxic at concentrations used.

Be wary of storage as activity will degrade over time.
