SMN2 modulator-1 is a brain-penetrant survival motor neuron (SMN) modulator. SMN2 modulator-1 post-translationally stabilizes SMN protein and increases SMN protein levels independent of SMN2 transcription. SMN2 modulator-1 can be used for the research of spinal muscular atrophy[1].

Description

SMN2 modulator-1 is a brain-penetrant survival motor neuron (SMN) modulator. SMN2 modulator-1 post-translationally stabilizes SMN protein and increases SMN protein levels independent of SMN2 transcription. SMN2 modulator-1 can be used for the research of spinal muscular atrophy[1].

[PMID: 28481536]
In Vitro

SMN2 modulator-1 (Compound 27) (0.29-30 μM; 24 h) potently activates SMN2 expression in SMN2 reporter cells with an EC50 of 0.29 μM, reaching 190% of control activity[1].
SMN2 modulator-1 (0.4-10 μM; 48 h) increases SMN protein levels in GM003813T SMA patient fibroblasts by approximately 2-fold at a 2 μM 48 h treatment, in a dose-dependent manner[1].
SMN2 modulator-1 has a kinetic solubility of 31 μM at pH 7.4, a mouse liver microsome half-life of 39 min, human liver microsome half-life of >120 min, and mouse plasma half-life of 326 min[1].
SMN2 modulator-1 (1-30 μM; 30 min-8 h) does not inhibit the proteasome or autophagy in HEK293 cells, nor does it inhibit HPV-16 E6 mediated p53 degradation in vitro, indicating its SMN-stabilizing effect is not due to global protein degradation inhibition[1].
SMN2 modulator-1 shows adequate intestinal permeability in the Caco-2 cell model, with an apical-to-basal Papp of 15 × 10-6 cm/s[1].

In Vivo

SMN2 modulator-1 (Compound 27) (20 mg/kg; i.p. or p.o.; single dose) achieves high plasma and brain exposure with favorable brain-to-plasma ratios after single intraperitoneal dosing, while oral dosing at the same dose results in moderate, lower exposure in adult mice[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
