Narciclasine, CAS No. 29477-83-6, is a toxic alkaloid found in various Amaryllidaceae species. Narciclasine is a potential allelochemical and affects subcellular trafficking of auxin transporter proteins and actin cytoskeleton dynamics in Arabidopsis roots. Narciclasine inhibits the responses of Arabidopsis roots to auxin. Narciclasine modulates polar auxin transport in Arabidopsis roots.

How to use

In Vitro:

Narciclasine activates Rho and stress fibers in glioblastoma multiforme cells. The mean IC50 of ~50 nM calculated on the 6 human glioblastoma multiforme (U373, Hs683, GL19, GL5, GL16, GL17), The mean IC50 value of 47 nM for Narciclasine across a panel of 60 cancer cell lines[1]. Bioassay-guided fractionation of the A. belladonna extract resulted in the identification of lycorine as the bio-active compound. The IC50 measured for radicle growth inhibition is 0.1 µM for Narciclasine.

In Vivo:

The i.v. regimen of Narciclasine at 1 mg/kg significantly (P=0.02) increases the survival of GL19 glioblastoma multiforme-bearing mice. Narciclasine when given orally at the same dose five times a week for 5 consecutive weeks also significantly increases animal survival in this model (P=0.008). Oral treatment with Narciclasine at 1 mg/kg significantly increases the survival (P=0.004) of Hs683 glioblastoma multiforme-bearing mice. Increasing the number of doses administered per week does not increase the survival of these Hs683 glioblastoma multiforme-bearing mice. Narciclasine appears to show similar increased survival in these models to temozolomide but at appreciable lower doses and following both oral and i.v. administration.
