(R)-(-)-JQ1 Enantiomer

Biological Activity

[Description]:

(-)-JQ-1 is the stereoisomer of (+)-JQ1. (+)-JQ1 potently decreases expression of both BRD4 target genes, whereas (−)-JQ1 has no effect.

[Target]

BET bromodomain[1]

[In Vitro]

(−)-JQ1 shows no significant interaction with any bromodomain. Besides, (−)-JQ1 enantiomer is comparatively inactive in nuclear protein in testis (NUT) midline carcinoma (NMC)[1].
