产品描述 Description

GR 127935 hydrochloride is a 5-HT1B/1D receptor antagonist that inhibits hypotensive responses [1]. GR 127935 hydrochloride can irreversibly antagonize the contraction of isolated canine basilar arteries and veins induced by sumatriptan, persistently antagonize hypothermia and rotational behavior mediated by 5-HT 1D receptors in guinea pigs, and block the central 5-HT1D auto-receptors both in vitro and in vivo[2]. GR 127935 hydrochloride has been widely used to regulate the basic locomotor activity of rats and prevent excessive activity [3].

In vitro, GR 127935 hydrochloride treatment for 48 hours significantly inhibited the replication of SARS-CoV-2 virus in HEK293T-ACE2-TMPRSS2 cells, with an EC50 value of 1.6µM[4].

In vivo, GR 127935 hydrochloride treatment via a single subcutaneous injection at a dose of 3mg/kg for 1 hour significantly reversed the increase in the brain reward threshold caused by RU 24969 (1mg/kg) in rats[5]. A single intraperitoneal injection of GR 127935 hydrochloride (10mg/kg) significantly reduced the 1-hour movement distance and decreased the axillary temperature in adult male and female rats[6].

GR 127935 hydrochloride是一种5-HT1B/1D受体拮抗剂，可抑制降压反应[1]。GR 127935 hydrochloride能不可逆地拮抗sumatriptan诱导的离体犬基底动脉和静脉收缩，持久拮抗豚鼠中由5-HT1D受体介导的体温降低和旋转行为，并在体外和体内阻断中枢5-HT1D自身受体[2]。GR 127935 hydrochloride已被广泛用于调节大鼠的基础运动活性并防止过度活动[3]。

在体外，GR 127935 hydrochloride处理 HEK293T-ACE2-TMPRSS2细胞48小时，显著抑制了SARS-CoV-2病毒的复制，EC50值为1.6µM[4]。

在体内，单次皮下注射3mg/kg剂量的GR 127935 hydrochloride 1小时，显著逆转了RU 24969 (1mg/kg)引起的大鼠脑内奖赏阈值的升高[5]。单次腹腔注射10mg/kg剂量的GR 127935 hydrochloride，显著减少了成年雄性和雌性大鼠在1小时内的移动距离，并降低了腋下温度[6]。

实验参考方法 Experimental Reference Method

Cell experiment [1]:

Cell lines

HEK293T-ACE2-TMPRSS2 cells

Preparation Method

HEK293T-ACE2-TMPRSS2 cells were maintained in high glucose DMEM complemented with 10% FBS, 100units of penicillin, and 100µg/ml streptomycin in a humidified incubator at 37°C and 5% CO2. The day before the pseudovirus assay, HEK-293T-hACE2-TMPRSS2 cells (0.5×106 cells per well) were seeded into a gelatin-coated 96-well plate (0.1%). The next day, two-fold serial dilutions of GR 127935 hydrochloride were prepared in 2% DMEM, producing final concentrations (0.02, 0.1, 1, 5, 10, and 15μM). The serially diluted GR 127935 hydrochloride was mixed in equal volumes with the virus (1×106 RLU/mL) supplemented with 10mg/ml hexadimethrine bromide and incubated for 30min at 37°C in a 5% CO2 incubator. Subsequently, each dilution was then added to HEK-293T cells expressing human ACE2-TMPRSS2. The plate was then incubated at 37°C in a 5% CO2 incubator for 60h, after which the cell lysate was prepared and used for the luciferase assay.

Reaction Conditions

0.02, 0.1, 1, 5, 10, and 15μM; 60h

Applications

GR 127935 hydrochloride treatment significantly inhibited the entry of pseudovirus particles into HEK293T-ACE2-TMPRSS2 cells in a dose-dependent manner.
Animal experiment [2]:

Animal models

Sprague-Dawley rats

Preparation Method

Sprague-Dawley rats were housed in large polycarbonate maternity cages on ventilated racks at 22-23°C and kept under a 12:12 light/dark cycle. Food and water were freely available. Behavioral testing was done in activity monitoring chambers that consisted of acrylic walls, a plastic floor, and an open top. Each chamber included an X-Y photobeam array, with 16 photocells and detectors, that was used to determine distance traveled (locomotor activity). Rats were injected intraperitoneally with saline vehicle or GR 127935 hydrochloride (10mg/kg) and immediately placed in activity chambers, where distance traveled (i.e., horizontal locomotor activity) was measured for 60min.

Dosage form

10mg/kg for once; i.p.

Applications

GR 127935 hydrochloride treatment significantly reduced the 1-hour movement distance in rats.
