Merenskine N-oxide

Merenskine N-oxide is a jacobine-like chlorinated 1,2-unsaturated pyrrolizidine alkaloid N-oxide with a hydroxyl group at the α-position. Merenskine N-oxide has a halohydrin side-chain configuration and serves as a substrate for epoxidation reactions. The transfer rate of Merenskine N-oxide into black tea leachate is pH-dependent, and its transfer rate decreases significantly under alkaline conditions.

Biological Activity

Description

In Vitro

Merenskine N-oxide (100 ng/mL; 50 °C) undergoes epoxidation in an aqueous solvent matrix to form Merepoxine N-oxide, with a conversion yield ranging from 40% to 87%^[2].
Merenskine N-oxide (2.5 ng/mL; 5 min) exhibits pH-dependent transfer characteristics to black tea infusions, with the transfer rate dropping to 3% at pH 9 and being higher under acidic conditions^[3].

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.
