SMN2-Stablizer-27 is a stablizer of survival of motor neuron 2 (SMN2), and a post-translationally stablizing SMN protein for the treatment of spinal muscular atrophy (SMA).
Homocarbonyltopsentin is a small-molecule TSL2-binding compound, binds to pentaloop conformations of TSL2 and promotes a shift to triloop conformations that display enhanced SMN2 exon 7 (E7) splicing (EC50: 16 μM).
Branaplam is a highly potent, selective and orally active SMN2 splicing modulator. Branaplam increases the amount of functional SMN protein produced by the SMN2 gene through modifying its splicing.
NVS-SM2 is an effective small molecule splicing enhancer of SMN2 with oral activity. NVS-SM2 showed increased exon 7 inclusion and upregulated SMN protein expression in SMA fibroblasts and SMN cells Δ7 5025 mouse myoblasts.
