Impurity Rocuronium EP Impurity C Applications 17-Desacetyl Rocuronium Bromide (Rocuronium EP Impurity C) is a metabolite of Rocuronium (R639500), in human plasma. References Kleef, U., et al.: J. Chromatogr., 621, 65 (1993), Proost, J., et al.: Br. J. Anaesth., 85, 717 (2000),

Stability Hygroscopic Applications Taurochenodeoxycholic Acid-d5 (Major) Sodium Salt is the labelled analogue of Taurochenodeoxycholic Acid (T008130), a bile acid conjugate and metabolite Taurolithocholic Acid (T009100) with antiinflammatory activity. Taurochenodeoxycholic Acid has been shown to inhibit hepatocyte apoptosis through suppression of Bid translocation to mitochondria. References Emerman, S. et al.: J. Biol.

Applications (3α)-Pregnanolone Sulfate is the sulfate conjugate of (3α)-Pregnanolone (P711300). Pregnanolone Sulfate is an endogenous neurosteroid that inhibits NMDA receptors and is neuroprotective in vivo. References Kussius, C.L. et al.: J.

Applications One of the thyroid hormones involved in the maintenance of metabolic homeostasis. Synthesized and stored as amino acid residues of thyroglobulin, the major protein component of the thyroid follicular colloid. Synthesis and secretion are regulated by the pituitary hormone (TSH). Deiodinated in peripheral tissues to the active metabolite, liothyronine. The D-form has very little activity as a thyroid hormone, but has been used to treat hyperlipidemia.
