Comparative studies of the ethynyl estrogens used in oral contraceptives. I. Endometrial response.
Reproductive-age women were given identically prepared mestranol or ethynylestradiol orally for two consecutive 21 day cycles in doses ranging from 50 to 100 mug per day. Endometrial biopsies were obtained at the end of the second cycle and assessed for estrogenic effect. At these dose levels and with this treatment regimen, no differences could be detected between doses or between drugs, indic...
متن کاملInteractions of synthetic estrogens with human estrogen receptors.
Synthetic estrogens have diverse chemical structures and may either positively or negatively affect the estrogenic signaling pathways through interactions with the estrogen receptors (ERs). Modeling studies suggest that 4-(1-adamantyl)phenol (AdP) and 4,4'-(1,3-adamantanediyl)diphenol (AdDP) can bind in the ligand binding site of ERalpha. We used fluorescence polarization (FP) to compare the bi...
متن کاملMetabolism of synthetic estrogens; urinary sulfur partitioning after estrogen administration.
In 1945 one of us reported in abstract (1) that little, if any, conjugation of diethylstilbestrol with sulfuric acid occurs in the rat and probably none at all in the rabbit. Since that time further interest in this subject has been evidenced by publications of experiments of the same type from other laboratories (see below). It seemed worth while, therefore, to extend our observations and publ...
متن کاملSynthetic studies on leupeptins and their analogs.
Leupeptins, fermentation products of various strains of Actinomycetes^ showed strong antiplasmin activity2) and were identified as being a mixture of two major components, leupeptin Ac-LL (acetyl-L-leucyl-L-leucyl-DL-argininal, 1) and leupeptin Pr-LL (propionyl-L-leucyl-L-leucyl-DL-argininal, 2), and their analogs containing isoleucine or valine in place of one or two leucine residues of 1 or 2...
متن کاملStudies on sintering process of synthetic hydroxyapatite.
In this study the effect of sintering process in different temperatures on microstructure and morphological properties of sintered hydroxyapatite (HAp) was investigated. HAp powder was prepared by wet precipitation method from following reagents: Ca(OH)2 + H3PO4 in an alkaline conditions. Thermal analysis (TA), X-Ray diffraction method (XRD), FT-IR spectrometry (FT-IR) and scanning electron mic...
