Branaplam (LMI070; NVS-SM1) hydrochloride 是一种口服有效和选择性的 SMN2 拼接调节剂，对 SMN 的 EC₅₀ 为 20 nM。Branaplam hydrochloride 抑制 hERG，IC₅₀ 为 6.3 μM。Branaplam hydrochloride 在严重的脊髓性肌萎缩症 (SMA) 小鼠模型中可提高全长 SMN 蛋白并延长其生存期。

Branaplam (LMI070; NVS-SM1) hydrochloride is a highly potent, selective and orally active survival motor neuron-2 (SMN2) splicing modulator with an EC 50 of 20 nM for SMN. Branaplam hydrochloride inhibits human-ether-a-go-go-related gene (hERG) with an IC 50 of 6.3 μM. Branaplam hydrochloride elevates full-length SMN protein and extends survival in a severe spinal muscular atrophy (SMA) mouse model.
