Beschreibung

Allopregnane is a C₂₁-type 5α-stane steroid derivative, a potent inhibitor of estrogen-induced chicken oviduct growth, and is present in the starfish Asterias amurensis^[1]^[2]^[3].

In Vitro

Allopregnane (5α-pregnane) derived seven compounds (three new steroidal sulfates, three known monosaccharide saponins, one new oligosaccharide saponins) are isolated and structurally characterized from starfish Asterias amurensis using NMR, HRESI-MS, and TDDFT-ECD, expanding the structural diversity of starfish saponins^[1].
Allopregnane (5α-pregnane) is detected as a trace sterane constituent in southern California municipal wastewater effluents from JWPCP, Hyp-5 mi, Hyp-7 mi, OCSD, and CSD treatment plants, with the sterane class present at concentrations ranging from <0.5-50 μg/L in unfiltered samples^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
