Anticonvulsant Interactions: Borneol and Scoparone

Check if the same lab product or an alternative is used in the 5 most similar protocols
All drugs—borneol, carbamazepine, phenytoin, phenobarbital and valproate—were purchased from Sigma-Aldrich (Poznań, Poland). scoparone was isolated from Artemisia umbelliformis Lam. (Asteraceae), as reported previously [19 (link)]. All the studied drugs, except for valproate (i.e., borneol, scoparone, carbamazepine, phenobarbital and phenytoin), were suspended in a 1% aqueous solution of Tween 80 (Sigma-Aldrich, Poznań, Poland), while valproate was dissolved in distilled water. The ASMs were administered intraperitoneally (ip) as follows: phenytoin—120 min, phenobarbital—60 min and carbamazepine and valproate—30 min, before the experiments, as reported earlier [39 (link),40 (link)]. borneol and scoparone were injected i.p. at increasing time periods of 15, 30, 60 and 120 min. Of note, these pretreatment times for borneol and scoparone when used separately (i.e., 15, 30, 60 and 120 min.) were based on our previously published work in order to make the results for scoparone comparable to those for other coumarins (i.e., osthole, imperatorin and xanthotoxin) tested earlier [10 (link),26 (link)]. For all the combinations with ASMs, both borneol and scoparone were administered i.p. 15 min. before the MES test and brain tissue sampling.

Three treatments were used to test the modulation of autophagy in oyster spat. Groups of spat were maintained for 24 or 48 h in seawater supplemented with dissolved (1) NH4Cl (Sigma-Aldrich, A9434) at a concentration of 0.53 g/10 L of seawater, (2) carbamazepine (Sigma-Aldrich, C4024) at a concentration of 0.071 g/10 L seawater, or (3) carbamazepine+NH4Cl at concentrations of, respectively, 0.071 g/10 L of seawater and 0.53 g/10 L of seawater [12]. One control condition was also used, which consisted of spat maintain only in the seawater. For each of the 4 conditions tested (3 treatments and 1 control), 6 tanks were used containing 13 oysters each. At each sampling time (24 and 48 h), 3 tanks of 13 animals were sampled per condition. At T0 (the time before oysters were incubated in the different test conditions), 3 pools of 13 oysters were sampled to record the basal level of autophagy in their hemocytes.

Check if the same lab product or an alternative is used in the 5 most similar protocols
C6 cells (American Type Culture Collection, Manassas, VA), with a passage number of 45, were cultured in Dulbecco’s Modified Eagle’s Medium supplemented with 10% fetal bovine serum and incubated at 37°C in a humidified atmosphere containing 5% CO2 and 95% air. Cells grown in 60-mm plates to 60% to 70% confluence were treated with mood stabilizers VPA, lithium, lamotrigine, carbamazepine, and HDAC inhibitors SB, PB, MC1568 (MC), SAHA, TSA, entinostat (MS275), apicidin, mocetinostat (Moce), or romidepsin (FK228) for 24 hours and then harvested for FGF21 mRNA analysis (VPA, lithium, lamotrigine, carbamazepine, SB, PB, SAHA, and TSA obtained from Sigma-Aldrich; MS275, apicidin, Moce, and FK228 obtained from Selleckchem). Cells grown on 25-mm circular glass cover slips were treated with the above drugs for 24 hours and stained with 0.5 μM calcein AM (Thermo Fisher Scientific), which emits a green color for live cell staining, and 5 μg/ml Hoechst 33258 (Sigma-Aldrich), which yields a blue color for cell nuclear staining (Zhu et al., 2002 (link)).

Quantifying Pharmaceutical Contaminants

Check if the same lab product or an alternative is used in the 5 most similar protocols
The target pharmaceutical compounds in this study were carbamazepine, ibuprofen, ciprofloxacin, sulfamethoxazole, erythromycin and clarithromycin, and were purchased from Merck Millipore (Gauteng, South Africa). The target compounds were selected based on global use. The standard solution (1000 µg/mL) of the target compounds were prepared by dissolving the weighed standard powder into methanol (High Performance Liquid Chromatography gradient-grade) purchased from Merck Millipore (Gauteng, South Africa). The structure and molecular weight of the target pharmaceuticals are shown in Table 2.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
