Potent Smoothened receptor agonist
4366 | SAG

Kd = 59 nM. Antagonizes cyclopamine action at the Smo receptor. Potently activates the Hedgehog signaling pathway in Shh-light 2 cells (EC50 ~ 3 nM); induces pathway activation independently of Ptch proteins. Enhances neuronal differentiation of iPSCs into dopaminergic neurons.

Potent and selective Iks channel blocker
5011 | HMR 1556

IC50 values are 10.5 and 34 nM in canine and guinea pig ventricular myocytes respectively. Selectively inhibits IKs currents over IKr, IKI, Ito and L-type calcium channel currents. Also has little or no effect on Kv11.1 Kv1.5, Kv1.3, Kir2.1 and HCN2 channel currents. Potentiates E-4031 -induced arrhythmias in vivo.
