Species
Animal Model
Administration Dosage Frequency Description References
Mice Forced Swimming Test (FST) Intraperitoneal injection 100 mg/kg Once a day for four consecutive days PCPA blocked the anti-immobility effect of Km, indicating that the antidepressant-like effect of Km is related to the serotonergic system. Molecules. 2014 Dec 19;19(12):21442-61
NOD/ShiLtJGpt-Prkdcem26/IL2rg em26/Gpt (NCG) mice AML xenograft model Intraperitoneal injection 15 mg/kg Single dose To evaluate the anti-tumor effect of LSD1 inhibitor (2-PCPA) combined with NK cell therapy in AML xenograft model Oncoimmunology. 2022 Jan 5;11(1):2016158
Rats Chronic constriction injury (CCI) model Intraperitoneal injection 150 mg/kg Three consecutive days To evaluate the effect of PCPA on the analgesic effect of ammoxetine, results showed that PCPA pretreatment abolished the antiallodynic effect of ammoxetine Acta Pharmacol Sin. 2016 Sep;37(9):1154-65
Rats 5-HT depletion model Intraperitoneal injection 200 mg/kg Four consecutive days PCPA treatment significantly reduced 5-HT content in the OFC and induced a reversal learning impairment, which was alleviated by acute or sub-chronic vortioxetine administration. Int J Neuropsychopharmacol. 2014 Oct;17(10):1695-706
C57BL/6J mice Ethanol-induced sedation/hypnosis model Intraperitoneal injection 250 mg/kg Once daily for 3 days PCPA treatment significantly reduced levels of 5-HT in hippocampus and cortex while NE levels were unaltered. PCPA treatment did not affect the sleep time response to ethanol. Neuropharmacology. 2008 Oct;55(5):803-11
Rats Preweanling and adolescent rats Intraperitoneal injection 3 × 200 mg/kg Once on PD 18, PD 19, and PD 20 PCPA partially attenuated MK801-induced locomotor activity in preweanling rats and adolescent female rats but had minimal effects on adolescent male rats. Psychopharmacology (Berl). 2020 Aug;237(8):2469-2483
Rats Preweanling rat model Intraperitoneal injection 3 × 200 mg/kg Injected on PD 18, PD 19, and PD 20, with the last injection 24 h before testing PCPA pretreatment significantly attenuated the RU 24969-induced locomotor activity of preweanling rats, while causing a small, yet significant, increase in basal locomotor activity Naunyn Schmiedebergs Arch Pharmacol. 2021 May;394(5):903-913
Rat 5-HT synthesis inhibition model Intraperitoneal injection 300 mg/kg Once daily for 3 days To investigate the effect of 5-HT depletion on STN neuron activity. Results showed that pCPA treatment increased the proportion of bursting firing patterns in STN neurons and elevated the mean firing rate of STN neurons. Psychopharmacology (Berl). 2014 May;231(9):1913-24
Rats Genetic model of depression Intraperitoneal injection 86 mg/kg/day 3 consecutive days To evaluate the role of endogenous stimulation of 5-HT1B heteroreceptors in the antidepressant-like activity of S-ketamine. Results showed that pCPA pretreatment significantly decreased cortical 5-HT concentration to 6.0% but did not affect the baseline behavioral phenotype of FSL rats. Front Pharmacol. 2018 Jan 15;8:978

Dissolving Methods
Please choose the appropriate dissolution scheme according to your animal administration guide.For the following dissolution schemes, clear stock solution should be prepared according to in vitro experiments, and then cosolvent should be added in turn:

in order to ensure the reliability of the experimental results, the clarified stock solution can be properly preserved according to the storage conditions; The working fluid for in vivo experiment is recommended to be prepared now and used on the same day;

The percentage shown in front of the following solvent refers to the volume ratio of the solvent in the final solution; If precipitation or precipitation occurs in the preparation process, it can be assisted by heating and/or ultrasound.
Protocol 1
Protocol 2
The prepared working fluid is recommended to be prepared now and used up as soon as possible in a short period of time. The percentage shown in front of the following solvent refers to the volume ratio of the solvent in the final solution; If precipitation or precipitation occurs in the preparation process, it can be assisted by heating and/or ultrasound.
