A natural apocarotenoid with diverse biological activities
Cas No.:27876-94-4
Sample solution is provided at 25 µL, 10mM.
Transcrocetin is a natural apocarotenoid isolated from C. sativus and G. jasminoides that has antioxidant, antiproliferative, anti-inflammatory, cardioprotective, and antinociceptive properties.1,2,3,4,5,6 It scavenges 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals (IC50 = 17.8 μg/ml) and inhibits growth of MKN28 stomach, MCF-7 breast, and Caco-2 colon cancer cell lines (IC50s = 53, 63, and 103 μM, respectively).2,3 Transcrocetin (20 μM) protects primary rat microglial cells from LPS-induced death and decreases LPS-induced production of intracellular reactive oxygen species (ROS), TNF-α, IL-1β, and NF-κB.4 Transcrocetin (100 mg/kg) increases the level of glutathione (GSH), catalase (CAT), creatine kinase (CK), and lactate dehydrogenase (LDH) in cardiac tissue in a rat model of myocardial infarction induced by isoproterenol .5 It also increases the pressure threshold and latency to withdrawal in response to mechanical and thermal stimuli, respectively, indicating a decrease in allodynia in a mouse model of spared nerve injury when administered intrathecally at a dose of 30 mg/kg.6

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; Transcrocetin 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]. |

DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
