Description

Homocarbonyltopsentin (PK4C9) 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 with EC50 value of 16 μM.

How to use

In Vitro:

Homocarbonyltopsentin (PK4C9) (10-40 μM; 24 hours) shows an up to 5.2-fold decrease in the expression of E7-excluding SMN2 isoforms, and up to three-fold increase in E7-including isoforms in GM03813C cells. Homocarbonyltopsentin (PK4C9) (40 μM; 24 hours) increased 1.5-fold SMN protein expression compared to GM03813C cells treated with DMSO.
