Background

Transcrocetinate disodium, extracted from saffron (Crocus sativus L.), acts as an NMDA receptor antagonist with high affinity.

Transcrocetinate (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. Transcrocetinate at 10 µM level does not change viability while higher concentrations (40-160 µM) reduces significantly cellular viability[1].

Protocol

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 μl FBS-free medium, grown for 96 h and followed by 24 h contact time with the test compounds (100 μL of serum-free media containing SE 0.5, 1, and 2 mg/mL; trans-crocin-1 250, 500, and 1000 μM; Transcrocetinate 10, 40, 80, and 160 μM) and incubation at 37°C/5% CO2. The incubation solutions are aspirated, each well is washed twice with 150 μL of PBS and 50 μL of MTT solution are added (2.5 mg/mL in PBS). Supernatants are discarded and the formed formazan is dissolved in 50 μL of DMSO. The absorption of the resulting solution is determined at λ=492 nm against reference wavelength λ=690 nm[1].
