Steroid Hormones Library

70 compounds

Steroid hormones (also known as steroidal hormones) are a class of tetracyclic aliphatic hydrocarbon compounds derived from cholesterol. Typical representatives of steroid hormones include cortisol, aldosterone, testosterone, estradiol, among others. These hormones serve diverse regulatory functions within the body. For instance, aldosterone helps maintain the homeostasis of extracellular fluid volume and circulating blood volume; testosterone and estradiol primarily promote the development and maturation of male and female reproductive organs and regulate reproductive functions.

MCE designs a unique collection of 70 steroid hormones. This library can be used for research related to metabolic or immune diseases, investigations into the mechanisms of action of nuclear receptor signaling pathways, as well as identification and quantitative analysis in metabolomics studies.

Org-30850 Org 30850ANT	GnRH Receptor	Endocrinology
Org-30850 is a potent LHRH antagonist designed for treating hormone-dependent disorders. In animal studies, a single subcutaneous dose effectively inhibited ovulation in rats and significantly reduced testosterone levels in male rats for up to 48 hours post-administration. Daily doses of Org-30850 in female rats suppressed estrous cycles, decreased uterine and ovarian weights, and lowered estradiol and FSH serum levels. In male rats, prolonged treatment resulted in reversible reductions in gonadal function and testosterone levels, with almost complete recovery observed after cessation of treatment. Unlike comparable LHRH antagonists, Org-30850 exhibited minimal injection site irritation and no edematous reactions, suggesting a more favorable therapeutic profile .

ORG 30276 treatment results in a considerable reduction in mRNA levels of gonadotropin beta-subunits in the pituitary gland. ORG 30276's effects on gonadotropin dynamics can be selectively reversed by the replacement of specific sex steroids, with androgens being particularly effective for the FSH beta-subunit mRNA levels.

Carbosulfan causes reproductive toxicity in male rats and developmental disorders in their offspring. Carbosulfan shows persistence in paddy field environments and potential hazards to non-target organisms, and it is commonly used in studies related to reproductive toxicity and environmental risk assessment .

Diethyl 2-hydroxy-3-methylsuccinate-13C
Diethyl 2-hydroxy-3-methylsuccinate- ¹³C (MALIC ACID, 3-METHYL-, DIETHYL ESTER- ¹³C) is the ¹³C-labeled Diethyl 2-hydroxy-3-methylsuccinate (HY-W502469).

HY-W142432S

Perfluoroundecanoic acid-13C7

Perfluoroundecanoic acid- ¹³C₇ is the ¹³C-labeled Perfluoroundecanoic acid (HY-W142432). Perfluoroundecanoic acid is a perfluoroalkyl substance (PFAS). Perfluoroundecanoic acid is an orally active oxidative stress inducer. Perfluoroundecanoic acid promotes macrophage M2 polarization, activates Wnt/β-catenin signaling and enhances β-catenin nuclear accumulation. Perfluoroundecanoic acid -induced M2 phenotype macrophage accelerates tumor progression in vitro and in vivo. Perfluoroundecanoic acid induces DNA damage, reproductive and pathophysiological dysfunctions via oxidative stress in male Swiss mice. Perfluoroundecanoic acid inhibits Leydig cell development in pubertal male rats via inducing oxidative stress and autophagy. Perfluoroundecanoic acid accelerates insulitis development in a mouse model of type 1 diabetes. Perfluoroundecanoic acid can be used for the study of ovarian cancer, type 1 diabetes and inflammation .

HY-W766130

Ethisterone-13C2

Ethisterone- ¹³C₂ (Pregneninolone- ¹³C₂) is the ¹³C-labeled Ethisterone (HY-B0487). Ethisterone (Pregneninolone; 17α-Ethynyltestosterone) is a synthetic steroidal estrogen, is an orally active steroidal contraceptive agent. Ethisterone has almost no effect on the phagocytic activity of the reticuloendothelial system in male guinea pigs, while in utero exposure can induce abnormalities in the urogenital system of offspring.
