Biological Activity

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).

Motor neurons differentiated from iPSCs with LDN 193189

iPS differentiation with LDN 193189

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 (Cat. No. 1614) followed by Retinoic acid (Cat. No. 0695) and Purmorphamine (Cat. No. 4551) 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®, Cat. No. AF1837) and the general neuronal marker, beta III tubulin (green, R&D Systems®, Cat. No. MAB1195). For visualization, the neurons were stained using Northernlights™ 557-conjugated Donkey anti-Goat Secondary Antibody (R&D Systems®, Cat. No. NL001) and Northernlights™ 493-conjugated Donkey anti-Mouse Secondary Antibody (R&D Systems®, Cat. No. NL009) and counterstained with DAPI (blue, Cat. No. 5748).

Efficient and effective inhibitor of BMP-like receptors
By Paul Humphreys on 12/11/2020
Application: Species: Human

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.

BMP pathway inhibitor that works really well
By Anonymous on 12/09/2019
Application: 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.
