The (-)-JQ1 stereoisomer has no appreciable affinity to BET bromodomains，it is the negative control of +JQ-1.

(+)-JQ1 is a BET bromodomain inhibitor, binding to all bromodomains of the BET family, but not to bromodomains outside the BET family.

Lipid 15, as disclosed in US Patent US 20250381150 A1 assigned to Genzyme Corporation, is an ionizable lipid used in lipid nanoparticles (LNPs) for targeted nucleic acid delivery. It features a specific structure that enables efficient encapsulation and transfection of mRNA into cells such as immune cells and hematopoietic stem cells. Experimental data show that LNPs containing Lipid 15 achieve over 80% transfection efficiency with sustained protein expression, outperforming other lipids.
