Transcrocetin meglumine salt, extracted from saffron (Crocus sativus L.), acts as an NMDA receptor antagonist with high affinity. NMDA receptor[1]
Transcrocetin (trans-Crocetin), a saffron metabolite originating from the crocin apocarotenoids, has been shown to exert strong NMDA receptor affinity and is thought to be responsible for the CNS activity of saffron.To ensure unchanged viability of Caco-2 cells throughout the transport experiments, cellular mitochondrial dehydrogenase activity of Caco-2 cells is measured by MTT assay after a 24 h incubation period with the test compounds: Hydroalcoholic saffron extract saffron extract (SE, 0.5-1 mg/mL) and crocin-1 (250-1000 µM) reveal no negative significant changes in cellular viability. Transcrocetin at 10 µM level does not change viability while higher concentrations (40-160 µM) reduces significantly cellular viability[1].

Cell experiment: | Cytotoxicity of test compounds is determined by MTT assay using Caco-2 cells in 96 well plates at a density of 20.000 cells per well in 200 ?l FBS-free medium, grown for 96 h and followed by 24 h contact time with the test compounds (100 ?L of serum-free media containing SE 0.5, 1, and 2 mg/mL; trans-crocin-1 250, 500, and 1000 ?M; Transcrocetin 10, 40, 80, and 160 ?M) and incubation at 37°C/5% CO2. The incubation solutions are aspirated, each well is washed twice with 150 ?L of PBS and 50 ?L of MTT solution are added (2.5 mg/mL in PBS). Supernatants are discarded and the formed formazan is dissolved in 50 ?L of DMSO. The absorption of the resulting solution is determined at λ=492 nm against reference wavelength λ=690 nm[1]. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
