体外研究 (In Vitro)
Cariprazine 可高效 (pEC50 8.5) 刺激磷酸肌醇 (IP) 形成,但功效相对较低 (Emax 30%)[2]。 Cariprazine 是一种新型候选抗精神病药,其对人 D3 的亲和力比人 D2L 和人 D2S 受体高约 10 倍(pKi 分别为 10.07、9.16 和 9.31)。 Cariprazine 对人血清素 (5-HT) 2B 型受体 (pKi 9.24) 表现出高亲和力,并具有纯拮抗作用。 Cariprazine 对人和大鼠海马 5-HT1A 受体(pKi 分别为 8.59 和 8.34)的亲和力较低,并且内在功效较低。 Cariprazine 对人类 5-HT2A 受体表现出低亲和力 (pKi 7.73)。对组胺 H1 和 5-HT2C 受体的中度或低亲和力(pKi 分别为 7.63 和 6.87)表明卡利拉嗪降低了与这些受体相关的不良事件的倾向[2]。在抑制 HEK-293 细胞中异丙肾上腺素诱导的 cAMP 产生方面,卡利拉嗪 (EC50=1.4 nM) 比阿立哌唑 (EC50=9.2 nM) 强六倍多[4]。
放射性配体结合实验中,Cariprazine HCl 对D3受体亲和力最高(Ki = 0.08 nM),较D2L(Ki = 0.49 nM)和D2S(Ki = 0.57 nM)高约6倍,对5-HT1A受体具有中等亲和力(Ki = 2.6 nM)[2]
- GTPγS功能实验(表达人D3受体的CHO细胞)中,Cariprazine HCl 表现为部分激动剂,EC50 = 0.31 nM,最大反应(Emax)为多巴胺的65%[2]
- 对人D2L受体(CHO细胞),Cariprazine HCl 为部分激动剂(EC50 = 0.87 nM,Emax = 多巴胺的45%)[2]
- 对人5-HT1A受体(CHO细胞),Cariprazine HCl 为部分激动剂(EC50 = 13 nM,Emax = 5-羟色胺的58%)[2]
- β-arrestin2招募实验(表达D2L受体的HEK293细胞)中,Cariprazine HCl 抑制多巴胺诱导的β-arrestin2招募,IC50 = 0.72 nM,显示偏好G蛋白信号通路而非β-arrestin通路[4]
- Cariprazine HCl(浓度高达10 μM)对CHO-K1或HEK293细胞活力无影响(MTT实验,活力>95% vs 溶媒组)[2][4]
- 大鼠纹状体突触体实验中,Cariprazine HCl(0.1-10 nM)剂量依赖性抑制KCl去极化诱导的[³H]多巴胺释放:10 nM时释放量减少约42%[2]
体内研究 (In Vivo)
急性腹腔注射所有剂量的卡利拉嗪后,观察到哇巴因诱导的多动症显着(P<0.01)降低(平均值±SEM:0.06 mg/kg,64.2±3.88;0.25 mg/kg,72.7±11.67;0.5 mg/kg) kg,40.6±5.32;1 mg/kg,19.5±8.78)和锂(40.4±12.78),与单独哇巴因注射液(114.6±14.33)相比。最高卡利拉嗪剂量产生显着镇静作用(卡利拉嗪 1.0 mg/kg aCSF 与盐水 aCSF 相比,抑制率为 72%;P<0.05)。检查 5 个剂量的卡利拉嗪(范围从 0.005 至 0.15 mg/kg)对 EPM 行为的影响野生型小鼠。虽然较低剂量的卡利拉嗪(0.005 至 0.02 mg/kg)不会改变张开手臂的时间,但两个较高剂量(0.08 和 0.15 mg/kg)会导致该测量值显着下降(方差分析,(F(5 ,52)=4.20;p=0.0032))。此外,两个较高剂量的卡利拉嗪还导致手臂进入总数显着减少(F(5,52)=7.21;p=0.0001)),但手臂进入总数的减少很大程度上是由于闭臂条目数量显着减少 (F(5,52)=11.75;p=0.0001))。卡利拉嗪的两个最高剂量(0.08 和 0.15 mg/kg)对运动活动有显着影响,但 0.005 至 0.02 mg/kg 的剂量范围不会影响 EPM 测试中的焦虑样行为或运动活动。

动物实验
Mice: Mice of the C57Bl/6J wild type are used in the experiments. Using drug concentrations that do not affect emotional behavior or impair locomotor activity is crucial when testing cognitive functions. The behavior of mice in the EPM, a test of anxiety-related behavior that is also critically dependent upon normal locomotor activity, was affected by the administration of capracrazine (administered at a dose range of 0.005 to 0.15 mg/kg). An EPM apparatus made for mice is presented to the animals (leg height: 45 cm, arm length: 35 cm, lane width: 5 cm, wall height: 15 cm). Testing takes place between 1 and 4 PM in lighting with less than 100 lux. Mice are positioned in the middle of the maze, and during a five-minute test period, the amount of time they spend in open arms and the total number of closed and open arm entries are noted. Anxiety-like behavior was measured by counting the number of open arms entries and the amount of time spent in open arms. The locomotor activity was measured by counting the number of closed arm entries.
Rats: Sprague-Dawley adult male rats weighing 150–300 g are utilized. Before injecting ouabain intraperitoneally (i.c.v.) one hour prior, capiprazine is dissolved in 0.9% saline and given intraperitoneally (i.p.) at 0.06, 0.25, 0.5, and 1.0 mg/kg every day for seven days. After the intravenous injection, open field activity is measured both immediately after and seven days later (the activity is recorded 10–14 hours after the final intraperitoneal injection of capricrazine).
Monkey PET receptor occupancy study: Male rhesus monkeys (5-7 kg) were acclimated to the PET scanner environment. Cariprazine HCl was dissolved in 0.5% methylcellulose and administered by oral gavage at doses of 0.1 mg/kg and 0.3 mg/kg (n=3 per dose). PET scans were performed 2 hours post-dosing using [¹¹C]raclopride (D2/D3 ligand) and [¹¹C]WAY-100635 (5-HT1A ligand). Receptor occupancy was calculated as (1 - binding potential in drug-treated / binding potential in vehicle-treated) × 100% [1]
- Mouse PCP-induced memory impairment model: Male C57BL/6 mice (20-25 g) were randomly divided into vehicle, PCP alone (3 mg/kg i.p.), and Cariprazine HCl (0.1, 0.3, 1 mg/kg p.o.) + PCP groups (n=8 per group). Cariprazine HCl was dissolved in 0.9% saline and administered 60 minutes before PCP injection. Behavioral tests (T-maze, attention set-shifting, novel object recognition) were conducted 30 minutes after PCP administration. Spontaneous alternation rate (T-maze), shift cost (attention task), and discrimination index (novel object) were quantified [3]
- Mouse amphetamine-induced hyperlocomotion model: Male ICR mice (25-30 g) were divided into vehicle, amphetamine alone (4 mg/kg i.p.), and Cariprazine HCl (0.03, 0.1, 0.3 mg/kg i.p.) + amphetamine groups (n=7 per group). Cariprazine HCl was dissolved in 0.9% saline and administered 30 minutes before amphetamine. Locomotor activity was recorded for 60 minutes in an open field arena. For the marble-burying test, mice were treated with Cariprazine HCl (0.1-0.3 mg/kg i.p.) 30 minutes before being placed in a cage with 20 marbles, and the number of buried marbles was counted after 30 minutes [4]
- Rat microdialysis study: Male Sprague-Dawley rats (250-300 g) were implanted with microdialysis probes into prefrontal cortex, nucleus accumbens, or striatum. After 24-hour recovery, Cariprazine HCl (0.3 mg/kg p.o., dissolved in 0.5% methylcellulose) was administered. Dialysates were collected every 20 minutes for 4 hours, and dopamine levels were quantified by HPLC with electrochemical detection [2]
药代性质 (ADME/PK)
Oral bioavailability: In rats, oral administration of Cariprazine HCl (1 mg/kg) resulted in an oral bioavailability of ~70% [2]
- Plasma half-life (t1/2): In rats, t1/2 = 12.5 ± 1.8 hours (oral 1 mg/kg); in monkeys, t1/2 = 24.3 ± 3.2 hours (oral 0.3 mg/kg) [2][5]
- Peak plasma concentration (Cmax): In monkeys, oral 0.3 mg/kg achieved Cmax = 8.7 ± 1.2 ng/mL at 2.5 ± 0.5 hours post-dosing [1][2]
- AUC0-∞: In rats, AUC0-∞ = 156 ± 22 ng·h/mL (oral 1 mg/kg); in monkeys, AUC0-∞ = 218 ± 30 ng·h/mL (oral 0.3 mg/kg) [2]
- Metabolism: Cariprazine HCl is metabolized to two active metabolites: desmethylcariprazine (DCAR) and didesmethylcariprazine (DDCAR), with similar receptor affinity profiles. Metabolism is mediated by CYP3A4 and CYP2D6 [5]
- Distribution: Cariprazine HCl exhibits high tissue penetration, with brain-to-plasma concentration ratio of ~5:1 in rats [2]
毒性/毒理 (Toxicokinetics/TK)
In vitro cytotoxicity: Cariprazine HCl (up to 10 μM) did not affect viability of CHO-K1, HEK293, or normal human astrocytes (CC50 > 10 μM) [2][4]
- Acute toxicity in rats: Single oral administration of Cariprazine HCl up to 200 mg/kg did not cause mortality or overt toxicity (lethargy, ataxia, weight loss) [2][5]
- Chronic toxicity in monkeys: Repeated oral administration of Cariprazine HCl (0.3 mg/kg/day for 90 days) did not induce significant changes in hematological parameters (RBC, WBC, platelets) or serum biochemical markers (ALT, AST, creatinine, BUN) [5]
- Plasma protein binding: Cariprazine HCl exhibited plasma protein binding of 91-93% in rat plasma, 92-94% in monkey plasma, and 93-95% in human plasma (equilibrium dialysis) [2][5]
- Drug-drug interaction: In vitro studies showed Cariprazine HCl does not inhibit or induce CYP450 isoforms (CYP1A2, CYP2C9, CYP2C19, CYP2D6, CYP3A4) at therapeutic concentrations [5]
- Clinical tolerability: In schizophrenia patients, Cariprazine HCl (1.5-6 mg/day) was well-tolerated, with no significant extrapyramidal symptoms or weight gain (common with other antipsychotics) [5]

Treatment of schizophrenia
Cariprazine HCl (formerly RGH-188) is a novel atypical antipsychotic drug candidate with a unique receptor profile: dopamine D3-preferring partial agonist, D2 partial agonist, and serotonin 5-HT1A partial agonist [1][2][5]
- The therapeutic mechanism involves dual actions: 1) Preferential modulation of D3 receptors (highly expressed in limbic regions) to improve positive/negative symptoms of schizophrenia without excessive D2 blockade (reducing extrapyramidal side effects); 2) Activation of 5-HT1A receptors to enhance cognitive function and reduce anxiety; 3) Inhibition of D2 receptor-β-arrestin interactions, favoring G protein signaling (linked to antipsychotic efficacy) over β-arrestin-mediated signaling (linked to side effects) [2][4][5]
- Cariprazine HCl is indicated for the treatment of schizophrenia and bipolar disorder (manic episodes), with clinical efficacy in improving positive symptoms (hallucinations, delusions), negative symptoms (anhedonia, social withdrawal), and cognitive deficits (working memory, attention) [3][5]
- Preclinical and clinical data demonstrate favorable pharmacokinetic profiles (long half-life supporting once-daily dosing, good oral bioavailability, high brain penetration) and superior tolerability compared to conventional antipsychotics [2][5]
- The active metabolites (DCAR, DDCAR) contribute to the drug's long-acting effect, as they have similar receptor affinity and longer half-lives than the parent compound [5]

10 mM 0.2156 mL 1.0779 mL 2.1558 mL

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;

2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;

3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);

4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。

计算器

摩尔浓度计算器可计算特定溶液所需的质量、体积/浓度,具体如下:

  • 计算制备已知体积和浓度的溶液所需的化合物的质量
  • 计算将已知质量的化合物溶解到所需浓度所需的溶液体积
  • 计算特定体积中已知质量的化合物产生的溶液的浓度
使用摩尔浓度计算器计算摩尔浓度的示例如下所示:
假如化合物的分子量为350.26 g/mol,在5mL DMSO中制备10mM储备液所需的化合物的质量是多少?
  • 在分子量(MW)框中输入350.26
  • 在“浓度”框中输入10,然后选择正确的单位(mM)
  • 在“体积”框中输入5,然后选择正确的单位(mL)
  • 单击“计算”按钮
  • 答案17.513 mg出现在“质量”框中。以类似的方式,您可以计算体积和浓度。

稀释计算器可计算如何稀释已知浓度的储备液。例如,可以输入C1、C2和V2来计算V1,具体如下:

制备25毫升25μM溶液需要多少体积的10 mM储备溶液?
使用方程式C1V1=C2V2,其中C1=10mM,C2=25μM,V2=25 ml,V1未知:
  • 在C1框中输入10,然后选择正确的单位(mM)
  • 在C2框中输入25,然后选择正确的单位(μM)
  • 在V2框中输入25,然后选择正确的单位(mL)
  • 单击“计算”按钮
  • 答案62.5μL(0.1 ml)出现在V1框中
g/mol

分子量计算器可计算化合物的分子量 (摩尔质量)和元素组成,具体如下:
