The in vitro effects of obstetric drugs on 15-hydroxyprostaglandin dehydrogenase activity were investigated. Enzyme activity was inhibited by indomethacin, methylergometrine maleate, Solcoseryl, conjugated estrogen and progesterone, and was activated only by isoxsuprine-HCL. Methylergometrine maleate and isoxsuprine-HCl, which have opposite functions on uterine muscle, also exerted contrary effects on enzyme activity. Inhibitory and stimulatory effects of these drugs suggested that they could directly regulate uterine activity and also indirectly influence the uterus due to their effects on prostaglandin catabolism in vivo.

UI MeSH Term Description Entries
D007213 Indomethacin A non-steroidal anti-inflammatory agent (NSAID) that inhibits CYCLOOXYGENASE, which is necessary for the formation of PROSTAGLANDINS and other AUTACOIDS. It also inhibits the motility of POLYMORPHONUCLEAR LEUKOCYTES. Amuno,Indocid,Indocin,Indomet 140,Indometacin,Indomethacin Hydrochloride,Metindol,Osmosin
D007556 Isoxsuprine A beta-adrenergic agonist that causes direct relaxation of uterine and vascular smooth muscle. Its vasodilating actions are greater on the arteries supplying skeletal muscle than on those supplying skin. It is used in the treatment of peripheral vascular disease and in premature labor. Duvadilan,Isoxsuprine Hydrochloride,Hydrochloride, Isoxsuprine
D008755 Methylergonovine A homolog of ERGONOVINE containing one more CH2 group. (Merck Index, 11th ed) Methylergobasin,Methylergometrin,Methergin,Methergine,Methylergometrine,Methylergometrine Maleate,Methylergonovine Maleate,Méthergin
D010920 Placenta A highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products. It includes a fetal portion (CHORIONIC VILLI) derived from TROPHOBLASTS and a maternal portion (DECIDUA) derived from the uterine ENDOMETRIUM. The placenta produces an array of steroid, protein and peptide hormones (PLACENTAL HORMONES). Placentoma, Normal,Placentome,Placentas,Placentomes
D011247 Pregnancy The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH. Gestation,Pregnancies
D011374 Progesterone The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS. Pregnenedione,Progesterone, (13 alpha,17 alpha)-(+-)-Isomer,Progesterone, (17 alpha)-Isomer,Progesterone, (9 beta,10 alpha)-Isomer
D004967 Estrogens Compounds that interact with ESTROGEN RECEPTORS in target tissues to bring about the effects similar to those of ESTRADIOL. Estrogens stimulate the female reproductive organs, and the development of secondary female SEX CHARACTERISTICS. Estrogenic chemicals include natural, synthetic, steroidal, or non-steroidal compounds.
