Source Prostaglandin E1 is contained in human seminal plasma in an amount of 25 microgram/ml Bergstrom_S , and has been found in ovine seminal plasma and seminal vesicle, human menstrual and amniotic flluid, human uterine endometrium, umbilical cord, placental vessels and decidua, frog spinal cord, rat adrenal, human and bovine thymus, frog intestine, rat fat tissue, and human phrenic nerve Horton_EW Speroff_L et al. Horton_EW Karim_SM et al. Karim_SM et al. Kirtland_SJ .
Chemical Synthesis Corey_EJ et al.
Metabolism Prostagalndin E1 is produced from H1 at almost the same rate of E2 synthesis from H2 by an enzyme of bovine seminal vesicle Ogino_N et al..
Biological Activity Prostaglandin E1 is generally considered as active as E2, and the biological activities of both compounds are compared in references Bergstrom_S et al. Horton_EW et al.. However, platelet aggregation is inhibited by prostaglandin E1 whereas prostaglandin E2 is much less active Bergstrom_S et al..
