体外研究 |
Tolmetin sodium dihydrate (0.25mM) does not attenuate lipid peroxidation in rat brain homogenate. Tolmetin (0.25,0.5,0.75,1mM) shows radical scavenging properties but without superoxide anion generation in rat brain homogenat.Tolmetin sodium dihydrate (0.001-100μM) shows anticancer activity againts HT-29 colon cancer cell line in a dosedependent manner.Tolmetin sodium dihydrate (0-100μM) shows no effect on osteoblast growth. |
|
体内研究 |
Tolmetin sodium dihydrate (30,100mg/kg;gavage;single dose or twice daily for 3 and 14 days) shows maximal ulcerogenic effect 4h after the single dose,while potently decreases after 3 and 14 days of repeated administration in male Wistar rats weighing 180-200g.Tolmetin causes gastric lesions in 100mg/kg.Tolmetin sodium dihydrate (5mg/kg twice a day for 5 days) pre-treatment considerably attenuates quinolinic acid (QA)-induced neurotoxicity. |
推荐实验方法(仅供参考)
动物实验: |
|
Rats After 2 weeks of acclimatization,rats are randomized to different groups and given the non-selective COX inhibitors,amtolmetin guacyl (AMG) (50 and 150mg/kg) and Tolmetin (30 and 100mg/kg) as well as the selective COX-2 inhibitor,celecoxib (CXIB;20 and 60mg/kg).The compounds are suspended in 1% carboxymethylcellulose (CMC) immediately before use and administered by gavage in a 10-mL/kg volume.Control groups receive CMC in the same volume.Rats from each group are divided into 3 subgroups,consisting each of at least 10 animals.Subgroups are dosed either with a single dose (acute treatment group) or twice daily for 3 and 14 days (chronic treatment groups).To ensure that all groups are dosed for the same period of time,those receiving less than 14 days of NSAIDs are given CMC until they are due to start the assigned treatment.Rats are killed by cervical dislocation 4h after the last administration.Stomachs are immediately removed,opened along the lesser curvature and gently rinsed. |
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系,公式为:
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
