Natural Product Identification
Common Nameprostaglandin-b1
DescriptionProstaglandin B1, also known as PGB1, belongs to the class of organic compounds known as prostaglandins and related compounds. These are unsaturated carboxylic acids consisting of a 20 carbon skeleton that also contains a five member ring, and are based upon the fatty acid arachidonic acid. Thus, prostaglandin B1 is considered to be an eicosanoid lipid molecule. Prostaglandin B1 blocks S-phase DNA synthesis; inhibition of DNA synthesis does not appear to require elevated levels of cAMP. Prostaglandin B1 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PGE1 is a prostanoid. Prostaglandin B1 exists in all living organisms, ranging from bacteria to humans. The PGs and TXs are collectively identified as prostanoids. prostaglandin-b1 is found in Homo sapiens and Larix sibirica. prostaglandin-b1 was first documented in 1983 (PMID: 6635328). Prostaglandin B1 has the ability to enhance peripheral vascular resistance and elevate blood pressure (PMID: 7667505) (PMID: 1477202) (PMID: 2129000) (PMID: 2597672).
