Orsellinic acid
Based on 1 Customer Validation
Orsellinic acid is a Benzoic acid (HY-N0216) derivative. Orsellinic acid can be isolated from Chaetomium globosum endophytic on Ephedra fasciculata (Mormon tea). Orsellinic acid blocks PAF-mediated Apoptosis, inhibits caspase-3/7 activation, and PARP cleavage. Orsellinic acid can be used in research of neurons and various tumors (non-small cell lung cancer, breast cancer, neuroblastoma, pancreatic cancer).

Orsellinic acid (10 μg/mL; 72 h) shows no cytotoxicity against four human tumor cell lines (NCI-H460, MCF-7, SF-268, MIA Pa Ca-2) and normal human fibroblast cells WI-38[2].
Orsellinic acid (1 μg/mL for cell survival test) specifically blocks platelet-activating factor (PAF)-mediated neuronal apoptosis in PAFR⁻/⁻ mouse cerebellar granule neurons (CGNs) and PC12-AC cells, inhibits caspase-3/7 activation and PARP cleavage[3].

Select the appropriate dissolution method based on your experimental animal and administration route.
- 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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (12.37 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (12.37 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL. * In solvent : -80°C, 6 months; -20°C, 1 month (protect from light)
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
