Biological Activity

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).

BMP pathway inhibitor that works really well
By Anonymous on 12/09/2019
Species: Human

I used it as a BMP pathway inhibitor in Breast cancer Cells. I used the concentration of 100nM and it works really well.
