Handling Instructions Technical Support

4-Chloro-L-phenylalanine (L-PCPA) is a tryptophan hydroxylase inhibitor targeting TPH1 and TPH2, with the activity of blocking serotonin biosynthesis. 4-Chloro-L-phenylalanine reduces the levels of serotonin and its metabolites in the brain without impairing the survival of serotonergic neurons. 4-Chloro-L-phenylalanine enhances anhedonic, depression-like and anxiety-like behaviors in mice with depleted noradrenergic and dopaminergic neurons. 4-Chloro-L-phenylalanine acts as a decarboxylation substrate for aromatic L-amino acid decarboxylase from Bacillus atrophaeus. 4-Chloro-L-phenylalanine can be used in studies related to Parkinson's disease.

제품 설명

4-Chloro-L-phenylalanine (L-PCPA) is a tryptophan hydroxylase inhibitor targeting TPH1 and TPH2, with the activity of blocking serotonin biosynthesis. 4-Chloro-L-phenylalanine reduces the levels of serotonin and its metabolites in the brain without impairing the survival of serotonergic neurons. 4-Chloro-L-phenylalanine enhances anhedonic, depression-like and anxiety-like behaviors in mice with depleted noradrenergic and dopaminergic neurons. 4-Chloro-L-phenylalanine acts as a decarboxylation substrate for aromatic L-amino acid decarboxylase from Bacillus atrophaeus. 4-Chloro-L-phenylalanine can be used in studies related to Parkinson's disease[1][2][3].

In Vitro

4-Chloro-L-phenylalanine (5 mM) is catalyzed for decarboxylation by purified AADC-BA from Bacillus atrophaeus[3].

In Vivo

4-Chloro-L-phenylalanine (300 mg/kg; i.p.; once daily; 3 consecutive days) reduces central 5-HT and 5-HIAA levels in mice, decreases 5-HT metabolic rate, and induces despair-associated depressive-like behavior without altering serotonergic neuron counts, locomotor activity, anxiety, or spatial cognition[1].
4-Chloro-L-phenylalanine (150 mg/kg/d; i.p.; daily; 3 consecutive days) reverses enhanced serotonin signaling-induced intestinal mucosal growth and enteric neuroplasticity in SERTKO and WT-SSRI mice, while only reducing villus height without affecting other parameters in WT mice[2].

Animal Model: C57BL/6 (male, 8 weeks of age)[1]
Dosage: 300 mg/kg
Administration: i.p.; once daily; 3 consecutive days
Result: Reduced frontal cortex 5-HT levels by 53% and 5-HIAA levels by 73% compared to saline controls; decreased the 5-HIAA/5-HT ratio by 42%.
Reduced hippocampus 5-HT levels by 57% and 5-HIAA levels by 76% compared to saline controls; decreased the 5-HIAA/5-HT ratio by 46%.
Did not significantly change the number of serotonin transporter-immunoreactive (SERT-ir) neurons in the dorsal raphe nucleus compared to saline controls.
Significantly increased immobility time in both the forced swim test and tail suspension test.
Did not alter locomotor activity, sucrose preference, anxiety-related behavior, or spatial learning/memory compared to saline controls.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
