  2. Steroids


A steroid is an organic compound with four rings arranged in a specific molecular configuration, composed of seventeen carbon atoms, bonded in four "fused" rings: three six-member cyclohexane rings (rings A, B and C in the first illustration) and one five-member cyclopentane ring (the D ring). Hundreds of steroids are found in plants, animals and fungi. Examples include the dietary lipid cholesterol, the sex hormones estradiol and testosterone and the anti-inflammatory drug dexamethasone. Steroids have two principal biological functions: certain steroids (such as cholesterol) are important components of cell membranes which alter membrane fluidity, and many steroids are signaling molecules which activate steroid hormone receptors.

Cholesterol plays an important role in determining the fluidity and permeability characteristics of the membrane as well as the function of both the transporters and signaling proteins. Cholesterol is also an endogenous estrogen-related receptor α (ERRα) agonist.

    2-Methoxyestradiol (2-ME2), an orally active endogenous metabolite of 17β-estradiol (E2), is an apoptosis inducer and an angiogenesis inhibitor with potent antineoplastic activity. 2-Methoxyestradiol also destablize microtubules. 2-Methoxyestradio, also a potent superoxide dismutase (SOD) inhibitor and a ROS-generating agent, induces autophagy in the transformed cell line HEK293 and the cancer cell lines U87 and HeLa.
  • HY-B0469
    Medroxyprogesterone acetate 71-58-9 99.88%
    Medroxyprogesterone acetate is a widely used synthetic steroid by its interaction with progesterone, androgen and glucocorticoid receptors.

    Ursodiol 128-13-2 ≥98.0%
    Ursodiol (Ursodeoxycholic acid; UDCA) is a potent liver-specific fatty acid transport protein 5 (FATP5) inhibitor. Ursodiol inhibit LCFA uptake by primary hepatocytes in a FATP5-dependent manner. Ursodiol reduces cholesterol absorption and is used to dissolve gallstones and has the potential for obesity-associated fatty liver disease research.

    Prednisolone 50-24-8 99.92%
    Prednisolone is a potent, orally active corticosteroid and a glucocorticoid. Prednisolone possesses about four times the anti-inflammatory activity of hydrocortisone while causing less salt and water retention. Prednisolone can be used for ocular, anti-inflammatory research.
  • HY-113313
    Aldosterone 52-39-1 ≥99.0%
    Aldosterone is the primary mineralocorticoid. Aldosterone is a steroid hormone, and it is synthesized and secreted in response to renin-angiotensin system activation (RAS) or high dietary potassium by the zona glomerulosa (ZG) of the adrenal cortex. Aldosterone activity is dependent by the binding and activation of the cytoplasmic/nuclear mineralocorticoid receptor (MR) at cellular level.
