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^[2].

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

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^[1].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 1.67 mg/mL (5.44 mM); Clear solution

This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 1.67 mg/mL (5.44 mM); Clear solution

This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 1.67 mg/mL (5.44 mM); Clear solution

This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 mg/mL) to 900 μL Corn oil, and mix evenly.

Protocol

Kinase Assay^[1]

The RhoA G-LISA assay is used. The assay uses a 96-well plate coated with the Rho binding domain of Rho family effector proteins. The active GTP-bound form of the Rho family protein but not the inactive GDP-bound form from biological samples will bind to the plate. Bound active Rho family protein is then detected by incubation with a specific primary antibody followed by a secondary antibody conjugated to horseradish peroxidase. The signal is then developed using OPD. U373 and GL19 glioblastoma multiforme cells are serum starved for 24 h and left untreated or treated with Narciclasine (100 nM) for 3 min, 5 min, 30 min, 1 h, and 2 h or treated with 2.0 μg/mL of the cell-permeable Rho inhibitor for 4 h in serum-free medium at 37°C with and without subsequent Narciclasine treatment. This product consists of highly purified C3 transferase covalently linked to a proprietary cell-penetrating moiety via a disulfide bond. The cell-penetrating moiety allows rapid and efficient transport through the plasma membrane. Once in the cytosol, the cell-penetrating moiety is released, thereby allowing C3 transferase to freely diffuse intracellularly and inactive RhoA, RhoB, and RhoC but not related GTPases such as Cdc42 or Rac1. C3 transferase inhibits Rho proteins by ADP ribosylation on Asn⁴¹ in the effector binding domain of the GTPase. Cells are then lysed and RhoA activity is measured by the RhoA G-LISA Activation Assay or alternatively cells are stained for F-actin^[1].

Cell Assay

Cell^[1]The Narciclasine IC₅₀ concentration, the Narciclasine concentration that decreased by 50% the global growth rate of a given cell population, is assessed with the MTT assay. The cells are incubated for 72 h in the presence and absence of the Narciclasine (with concentrations ranging between 10^-9 and 10^-5 M concentrate) for the determination of Narciclasine IC₅₀ values^[1].

Animal Administration^[1]

Mice^[1]
The Hs683 cell line and GL19 primoculture grafted into the brains of nude immunodeficient mice both produced invasive brain tumors. Xenograft-bearing mice receive vehicle alone, oral temozolomide at 40 mg/kg (5 administrations per week for 5 consecutive weeks), or Narciclasine at 1 mg/kg either oral (once per week for 5 weeks) or i.v. (twice per week for 5 weeks). Drug administration is initiated respectively on days 5 and 7 post-tumor grafting for the Hs683 and GL19 models. The temozolomide dose and treatment schedule are selected based on previous optimized regimens. Narciclasine dose and treatment schedule are selected based on Narciclasine toxicity study in rats after oral administration and pharmacokinetic study that we have recently published. In toxicity study, Narciclasine (25, 10, or 1 mg/kg) is administered five times a week for 3 weeks and the no adverse effect level dose is defined to be 1 mg/kg/d p.o., with minimal acanthosis reactive changes and minor variations in some biochemistry parameters observed at this dose level considered to be nonadverse.

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.
