生物活性
产品描述 |
一种新型的α7nAChR正向变构调节剂。在卵母细胞实验中,正调节α7nAChR,EC50为3.4μM。 |
靶点 |
EC50:3.4μM (α7 nAChR,in oocyte experiments) |
体外研究 |
NS 1738 acts by increasing the peak amplitude of acetylcholine (ACh)-evoked currents at all concentrations;thus,it increased the maximal efficacy of ACh.Plotting peak current amplitude against the logarithm of the NS 1738 concentration used for preincubation reveals a sigmoidal concentration-response relationship that is well fit by the Hill equation (EC50=3.4μM).Under similar experimental conditions,NS 1738 shows comparable efficacy and potency at the rat α7 nAChR (EC50=3.9μM). |
体内研究 |
To estimate the ability of NS 1738 to permeate the blood-brain barrier,rats are administered 10mg/kg NS 1738 intraperitoneally.Peak brain concentrations are measured approximately 30 min after injection,and they amount to ~80ng/mL (~200nM) at this dose.The ratio between the amount of compound entering the brain and that in plasma is AUCbrain/AUCplasma=0.50.The half-life in plasma is estimated to 42 min.Incubation of NS1738 with isolated liver microsomes in vitro indicates that approximately 60 and 75% of NS 1738 is metabolized via the cytochrome P450 system in mouse and rat,respectively,within 1h.Adult rats administered NS 1738 at 10 and 30mg/kg i.p.immediately following the initial exposure to a juvenile rat (T1) display significant decreases in the investigative duration of a subsequent exposure to the same juvenile (T2) 2 h later (T2/T1 ratio of 0.69±0.13 and 0.61±0.07,respectively). |
推荐实验方法(仅供参考)
动物实验: |
|
Rats Sprague-Dawley rats are used.Adult (2-4 months;400-450g) and juvenile (50-60g) animals are allowed to acclimate to the test room for 90 to 120 min before starting.After acclimation,adult rats are placed alone in their respective test cages.After a brief habituation period (30 min),they are allowed to interact for 5 min with a juvenile rat (trial;T1).During the interactive trial,the adult exhibits investigative behaviors that include close following,grooming,and/or sniffing of the juvenile for as much as 40 to 50% of the trial duration.The time of the investigative interaction is recorded in seconds.The juvenile rat is then removed,and the adult rats are immediately administered varying doses of NS 1738 (10 and 30mg/kg NS-1738 i.p.) [prepared in 5% ethanol/95% hydroxypropyl-B-cyclodextrin (34% solution);2.0mL/kg i.p.] or Nicotine (0.1mg/kg i.p.),and then they are returned to their home cage.A second 5-min interactive trial (T2) is conducted 120 min later in the same test cage,and investigative behavior of the adult rat is again monitored and the time is recorded. Recognition ratios of time spent investing the familiar juvenile in T2 divided by time spent investigating the juvenile in T1 are calculated. |
