Prochloraz (Prelude) is a broad-spectrum contact imidazole fungicide. Prochloraz inhibits human placental microsomal aromatase in vitro (IC50 = 40 nM). Prochloraz also acts as an estrogen receptor (IC50s = 25 μM) and androgen receptor (IC50 = 4 μM) antagonist, and activates aryl hydrocarbon receptors (EC50 = 1 μM).

Progesterone (Pregn-4-ene-3,20-dione) is 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.

Estrone (Aquacrine) is an aromatized C18 steroid with a 3-hydroxyl group and a 17-ketone, a major mammalian estrogen. It is converted from ANDROSTENEDIONE directly, or from TESTOSTERONE via ESTRADIOL. In humans, it is produced primarily by the cyclic ovaries, PLACENTA, and the ADIPOSE TISSUE of men and postmenopausal women.

Estriol (Oestriol) is a hydroxylated metabolite of ESTRADIOL or ESTRONE that has a hydroxyl group at C3, 16-alpha, and 17-beta position. Estriol is a major urinary estrogen. During PREGNANCY, a large amount of estriol is produced by the PLACENTA.

YM 511 is a highly specific non-steroidal aromatase inhibitor. YM 511 inhibits aromatase activities in microsomes from rat ovary and human placenta competitively (IC50s of 0.4 and 0.12 nM, respectively). YM 511 slightly inhibits production of other steroid hormones. YM 511 has the potential for suppressing estrogen-dependent action research without affecting serum levels of other steroid hormones.

eukaryotic translation elongation factor 1 alpha 1 (EEF1A1) encodes an isoform of the alpha subunit of the elongation factor-1 complex, which is responsible for the enzymatic delivery of aminoacyl tRNAs to the ribosome. This isoform (alpha 1) is expressed

eukaryotic translation elongation factor 1 alpha 1 (EEF1A1) (387-394) [Multiple species](TFA) is Elongation factor 1 subunit.eukaryotic translation elongation factor 1 alpha 1 (EEF1A1) encodes an isoform of the alpha subunit of the elongation factor-1 complex, which is responsible for the enzymatic delivery of aminoacyl tRNAs to the ribosome. This isoform (alpha 1) is expressed in the brain, placenta, lung, liver, kidney, and pancreas, and the other isoform (alpha 2) is expressed in the brain, heart, and skeletal muscle. This isoform is identified as an autoantigen in 66% of patients with Felty syndrome. This gene has been found to have multiple copies on many chromosomes, some of which, if not all, represent different pseudogenes1.

IgG has four forms, provides the majority of antibody-based immunity against invading pathogens. The only antibody capable of crossing the placenta to give passive immunity to the fetus. Eliminates pathogens in the early stages of B cell-mediated (humoral

β-Endorphin (β-EP) is an endogenous opioid neuropeptide with diverse biological activities. It is produced via piomelanocortin cleavage in the pituitary gland, hypothalamus, and in lymphocytes, then migrates to its sites of action which include plasma, gut, skin, placenta, cerebrospinal fluid, and cardiac tissues. β-EP induces concentration-dependent decreases in electrically stimulated contraction of the mouse vas deferens that can be reversed by the μ-opioid antagonist CTP and δ-opioid antagonist ICI 174,864. In vivo, β-EP (5 μg, i.c.v.) slows gastrointestinal transit in mice. β-EP (0.5 or 5 μg, i.c.v.) stimulates food intake in rats for 4 to 6 hours, however, this effect is not prolonged with continuous infusion. It antagonizes the appetite-suppressive effects of α-melanocyte-stimulating hormone (α-MSH) for the first three days post administration. β-EP also reduces paralytic demyelination induced by the murine coronavirus MHV-JHM in immunocompetent, but not irradiated or immune-incompetent, mice and rats.

MAGE-3 (271-279) is a peptide consisting of 271-279 amino acid residues derived from melanoma antigens encoded by the MAGE-3 gene. It is specifically recognized by cytolytic T lymphocytes (CTLs) and binds to the human leukocyte antigen (HLA)-A2 molecule. MAGE-3 is highly expressed in various human tumor types, such as malignant melanoma, but not in normal tissues, except for the testis and placenta.

Steroid Sulfatase-IN-6 (Compound 10c) serves as an irreversible steroid sulfatase (STS) inhibitor, exhibiting a K i value of 0.4 nM against human placenta STS, and is applicable in tumor disease research [1].

16α-Hydroxy-17β-estradiol-2,4-d2 is a deuterated compound of Estriol. Estriol has a CAS number of 50-27-1. Estriol is a hydroxylated metabolite of ESTRADIOL or ESTRONE that has a hydroxyl group at C3, 16-alpha, and 17-beta position. Estriol is a major urinary estrogen. During PREGNANCY, a large amount of estriol is produced by the PLACENTA.

Estrone-d4 is a deuterated compound of Estrone. Estrone has a CAS number of 53-16-7. Estrone is an aromatized C18 steroid with a 3-hydroxyl group and a 17-ketone, a major mammalian estrogen. It is converted from ANDROSTENEDIONE directly, or from TESTOSTERONE via ESTRADIOL. In humans, it is produced primarily by the cyclic ovaries, PLACENTA, and the ADIPOSE TISSUE of men and postmenopausal women.

Relaxin C-peptide, as a synthetic 14-amino acid peptide found in human decidua & placenta, can represent a partial sequence of human relaxin connecting peptide.
