Merenskine

Merenskine is a chlorinated 1,2-unsaturated senecionine-type pyrrolizidine alkaloid and serves as a substrate for epoxidation reactions. Merenskine forms merepoxine N-oxide upon evaporation in ammoniated solvents, while it generates merepoxine under alkaline sample preparation conditions. Merenskine exhibits a pH-dependent transfer rate in black tea infusion, and the transfer rate decreases sharply under alkaline conditions.

Biological Activity

Description

In Vitro

Merenskine (5-100 μg/mL) and its N-oxide are pyrrolizidine alkaloids not naturally present in Jacobaea species^[1].
Merenskine undergoes significant degradation (up to 99% loss) when brewed in alkaline (pH 9) tea infusion conditions, alongside Jaconine and Merenskine N-oxide^[2].
Merenskine (2.5 ng/mL; 5 min) exhibits pH-dependent transfer from fortified black tea to infusions, with transfer rates dropping to 2% at pH 9^[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.
