SMS2-IN-1 is an effective and highly selective sphingomyelin synthetase 2 (SMS2) inhibitor with IC50 of 6.5 nM and Kd of 37 nM. Sms2-in-1 is 150 times more selective to SMS2 than SMS1 (IC50 is 1000 nM).

SMS2-IN-2 (SMS2 inhibitors) is a potent, selective and orally active sphingomyelin synthase 2 (SMS2) inhibitor, (IC50s of 100 and 56 μM for SMS2 and SMS1, respectively). SMS2-IN-2 has anti-chronic inflammatory activity.

Sphingomyelins (SMs) are bioactive sphingolipids found in mammalian cell membranes.1SMs make up 2-15% of the total organ phospholipid population but are found at higher concentrations in the brain and myelin sheaths surrounding peripheral nerves. They interact with cholesterol to control its distribution within cellular membranes and maintain cholesterol homeostasis in cells. SMs undergo hydrolysis by sphingomyelinase to form ceramides, which are sphingolipid mediators of intracellular signaling.2This product is a mixture of SMs, with variable fatty acyl chain lengths, isolated from buttermilk.

Sphingomyelins (SMs) are bioactive sphingolipids present in the cell membranes of mammals, constituting 2-15% of the total cellular phospholipid content, with higher concentrations in the brain and myelin sheaths of peripheral nerves. These compounds play a crucial role in modulating cholesterol distribution and maintaining cellular cholesterol balance. SMs are hydrolyzed by sphingomyelinase into ceramides, key sphingolipid signaling molecules. The product contains SM species predominantly with C16:0 fatty acyl chain lengths and may exhibit variations in its sphingoid backbone due to its natural origin. [Matreya, LLC. Catalog No. 1332]
