Compounds for treating spinal muscular atrophy

In one aspect, described herein is an intronic recognition element for splicing modifier (iREMS) that can be recognized by a compound provided herein. In another aspect, described herein are methods for modulating the amount of a product of a gene, wherein a precursor RNA transcript transcribed from the gene contains an intronic REMS, and the methods utilizing a compound described herein. More particularly, described herein are methods for modulating the amount of an RNA transcript or protein product encoded by a gene, wherein a precursor RNA transcript transcribed from the gene comprises an intronic REMS, and the methods utilizing a compound described herein. In another aspect, provided herein are artificial gene constructs comprising an intronic REMS, and uses of those artificial gene constructs to modulate protein production. In another aspect, provided herein are methods for altering endogenous genes to comprise an intronic REMS, and the use of a compound described herein to modulate protein produced from such altered endogenous genes.

Methods for modulating RNA splicing

Described herein is an intronic recognition element for splicing modifier (iREMS) that can be recognized by a small molecule splicing modifier compound of Formula (I) provided herein or a form thereof, wherein W, X, A and B are as defined herein. In one aspect, methods for modifying RNA splicing to modulate the amount of a product of a gene, wherein a precursor RNA transcript transcribed from the gene that contains an intronic REMS is modified utilizing a splicing modifier compound of Formula (I), are described herein. In another aspect, methods for modifying RNA splicing to modulate the amount of an RNA transcript or protein product encoded by a gene, wherein a precursor RNA transcript transcribed from the gene is modified to comprise an intronic REMS utilizing a splicing modifier compound of Formula (I), are described herein.
