Treprostinil is a stable analog of prostacyclin (Item No. 18220) that is used clinically for the treatment of PPH under the trade name Remodulin™. The structural modifications in treprostinil compared to prostacyclin increase the plasma half-life from 2 minutes to 34 and 85 minutes for…

A bioactive sterol that can affect cholesterol homeostasis, membrane properties and cell survival; inhibits CYP7A1 with an IC₅₀ = ~ 1 µM; can be used as a standard in the determination of cholesterol derivatives by GC-MS or HPLC.

C-8 ceramide is a cell-permeable analog of naturally occurring ceramides. Unlike C-2 ceramide, it is metabolized within cells to generate natural ceramides, often causing a dramatic increase in cellular ceramide levels. For this reason, treatment of cells with C-8 ceramide may more closely mimic…
