Prostaglandin A1 (PGA1) was first isolated as a dehydration product of the PGE1 compounds found in human semen. It has been shown to cause renal vasodilation, increased urine sodium excretion, and lowered arterial pressure in hypertensive patients. It also has growth-inhibitory activity on tumor cells; the IC50 value for the inhibition of human ovarian cancer is 7.5 μM.
Prostaglandin A1 has been shown to inhibit human immunodeficiency virus type 1 (HIV-1) replication in various cell types. In addition, as a precursor to the anti-inflammatory prostaglandins, it activates pro-inflammatory PGD2 receptor CRTH2 initiating the anti-inflammatory response.
ChEBI: Prostaglandin A1 is a prostaglandins A. It is a conjugate acid of a prostaglandin A1(1-).
Prostaglandin A1(PGA1) belongs to the class of cyclopentenone prostaglandin. PGA1 is generated by the dehydration of prostaglandin E1 (PGE1).
Prostaglandin A1 (PGA1) boosts the expression of human liver-specific cytochrome P450 4F3B (CYP4F3B) and stimulates the synthesis of 20-hydroxy-eicosatetraenoic acids (HETEs). It has an ability to stimulate cell differentiation, ferritin synthesis and heat shock response in human cells. PGA1 exhibits antitumor and antiviral activities. In addition, it also elicits anti-inflammatory effects by activating peroxisome proliferator-activated receptor (PPAR). Elevated levels of PGA1 has been observed in hypertension patients.
This eicosanoid (FWfree-acid = 336.47 g/mol; CAS 14152-28-4; Symbol: PGA1) induces apoptosis and stimulates the expression of stress genes. The structure and role of the prostaglandin A1 was investigated by Bergstr?m and Samuelsson, who shared the 1982 Nobel Prize in Physiology or Medicine for their pioneering work on the eicosanoids. Target(s): CYP4F2; DNA topoisomerase II; HIV-1 transcription; 3ahydroxysteroid dehydrogenase, NADP+-dependent; IkB kinase; Mayaro virus replication; stress-induced NF-kB activation; and virus protein biosynthesis, or translation.
