15(S)-15-methyl Prostaglandin D2 (CAS 85280-90-6)

15(S)-15-methyl Prostaglandin D2 is a synthetic analog of prostaglandin D2 (PGD2), a naturally occurring bioactive lipid derived from arachidonic acid through the cyclooxygenase (COX) pathway. This compound is characterized by the addition of a methyl group at the 15th carbon position, which enhances its stability and alters its biological activity. In research, 15(S)-15-methyl Prostaglandin D2 is primarily used to study the signaling mechanisms and biological effects of PGD2, particularly its role in inflammatory and immune responses. The methylation at the 15th position provides resistance to enzymatic degradation by 15-hydroxyprostaglandin dehydrogenase, making it a more potent and longer-lasting analog compared to the native PGD2. This modification allows researchers to probe the effects of sustained PGD2 receptor activation, especially the DP1 and DP2 receptors, which are involved in the regulation of smooth muscle contraction, inhibition of platelet aggregation, and modulation of allergic and inflammatory responses. 15(S)-15-methyl Prostaglandin D2 is also used to explore the role of PGD2 in neuroinflammation and its potential impact on the central nervous system, making it a valuable tool in the study of prostaglandin signaling pathways and their broader physiological implications. This compound′s stability and potency make it an essential analog for understanding the complex roles of prostaglandins in various biological processes.
