Lasiocarpine

Customer Review

Based on 1 Customer Validation

Lasiocarpine, a hepatotoxic pyrrolizidine alkaloid (PA), causes fatal liver veno-occlusive disease in vivo. Lasiocarpine is toxic only after its metabolic conversion to the toxic intermediate, including dehydrolasiocarpine and N-oxide.

In Vitro

Lasiocarpine is toxic only after its metabolic conversion to the toxic intermediate, known as dehydrolasiocarpine^[1].
Dehydrolasiocarpine and other putative didehydropyrrolizidine alkaloids (the pyrrolic esters) are very reactive,they attack nucleophilic macromolecules such as DNA and proteins, eliciting severe toxicities, including liver veno-occlusive disease and tumors^[1].
Lasiocarpine is mainly metabolized in vitro through five metabolic pathways, dehydrogenation, ester bond cleavage, demethylation^[1].

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.
