Picein is an antioxidant and anti-inflammatory agent. Picein can be isolated from the leaves of Picrorhiza kurroa. Picein reduces MDA levels and increases the levels of SOD, GPX and TAC. Picein alleviates oxidative stress and promotes bone regeneration in osteoporotic bone defects by inhibiting Ferroptosis (via activation of the Nrf2/HO-1/GPX4 pathway). Picein prevents scopolamine (HY-N0296)-induced passive avoidance memory impairment in rats. Picein can be used in research related to osteoporotic bone defects and Alzheimer's disease.

In Vitro

Picein (10-80 μM; 24 h) shows no toxicity to rat bone marrow mesenchymal stem cells (BMSCs), and Picein (80 μM; 2 h pretreatment followed by 24, 48, 72 h erastin incubation) significantly restores the viability of rat BMSCs impaired by Erastin^[1].
Picein (80 μM) significantly restores the viability of HUVECs impaired by Erastin^[1].
Picein (80 μM; 48 h) significantly promotes M2 polarization of Raw 264.7 macrophages and reverses the inhibitory effect of 5 μM erastin^[1].
Picein (for 7-21 days) significantly reverses the inhibitory effect of 5 μM erastin on osteogenic differentiation of rat bone marrow mesenchymal stem cells (BMSCs), which is verified by increased alkaline phosphatase (ALP) activity, enhanced mineralization level, and upregulated expression of osteogenesis-related proteins and genes^[1].
Picein reduces ROS levels and restores mitochondrial function in neuroblastoma SH-SY5Y cells treated with Menadione (HY-B0332), indicating its potential as a neuroprotective agent^[3].

In Vivo

Picein (40-80 mg/kg; topical to femoral condyle; daily; 4 weeks) promotes bone regeneration in ovariectomized rats with osteoporotic femoral condyle defects, with the 80 mg/kg dose yielding a 48% BV/TV, and reduces local and systemic inflammation by lowering IL-1β, IL-6, and TNF-α levels^[1].
Picein (1.25-5 mg/kg; i.c.v.; daily; 7 days), most potently at 2.5 mg/kg, reduces hippocampal oxidative stress, increases neuronal density, and reverses scopolamine-induced passive avoidance memory impairment in male Wistar rats^[3].

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: ≥ 5 mg/mL (16.76 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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% (20% SBE-β-CD in Saline)

Solubility: ≥ 5 mg/mL (16.76 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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

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.
