In Vivo

Methoxsalen (15mg/kg, i.p, single dose) increases nicotine’s C_max prolongs the plasma nicotine half-life (fourfold increase), decreases its clearance (sixfold decrease), and increases its AUC^[1].
Methoxsalen (15mg/kg, i.p, single dose) enhances the potency of pharmacological effects of oral nicotine (i.e., body temperature and analgesia)^[1].

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

Animal Model:

Male adult ICR mice^[1]
Dosage:

15 mg/kg
Administration:

Intraperitoneal injection (i.p.), single dose
Result:

Increased nicotine plasma levels were still above 10ng/ml at 6hr.
Induced nicotine’s antinociceptive and hypothermic lasted close to 6 and 24 hr.

Metabolism of Methoxsalen (xanthotoxin), 2-tridecanone, and indoxacarb by recombinant P450s. CYP6AE subfamily enzymes were from H. armigera and CYP6B1 from Papilio polyxenes. Error bars represent mean values ± SEM (n = 4). Asterisk indicates that no significant metabolism was detected (limits of detection were 0.081, 0.033, and 0.016 pmol/min/pmol P450 for Methoxsalen (xanthotoxin), 2-tridecanone, and indoxacarb, respectively).

The results showed that the CYP6AE19 and CYP6AE20 transcripts (>1000-fold induction in midgut and >100-fold induction in fat body) are very strongly induced by Methoxsalen (xanthotoxin). Furthermore, CYP6AE14 transcripts are induced in midgut (40-fold) after dietary exposure to gossypol.

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: ≥ 2.5 mg/mL (11.56 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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% Corn Oil

Solubility: ≥ 2.5 mg/mL (11.56 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 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 (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
