MS4322 (isomer)

Target: MS4322 isomer is a stereochemical analog of the PRMT5 degrader MS4322.

Binding site: Its PRMT5-recognition element is designed for the PRMT5 catalytic binding region.

Mechanism of action: MS4322 (isomer), also called YS43-22 isomer, is an isomeric analog of the selective PRMT5 PROTAC degrader MS4322. It preserves the general PRMT5-ligand, linker, and E3-ligase-recruiting design logic of the MS4322 series, making it useful for comparative structure-activity studies around PRMT5 degradation. In experimental workflows, this compound can help assess how stereochemical configuration affects PRMT5 engagement, ternary-complex productivity, ubiquitination, and degradation efficiency. It is best positioned as a closely related analog for validating PRMT5 degrader design rather than as an independently characterized benchmark degrader.

• PROTAC-Mediated Kinase Degradation: MS4322 (isomer) is utilized in studies focused on the selective degradation of kinases.
