Cyclobenzaprine
Cyclobenzaprine (MK130) is an orally active 5-HT2 receptor antagonist. Cyclobenzaprine acts centrally, providing skeletal muscle relaxation, alleviating muscle spasms, and reducing pain. Cyclobenzaprine also possesses antiparasitic activity. Cyclobenzaprine holds promise for research in the fields of acute, painful skeletal muscle disorders and infectious diseases.

5-HT2 Receptor |
Cyclobenzaprine (0-50 μM, 72 h) demonstrates a concentration-dependent activity in Leishmania infantum promastigotes growth, with an IC50 value of 14.5 μM[4]. Cyclobenzaprine (0-50 μM, 72 h) reduces the number of intracellular amastigotes in Leishmania infantum-infected macrophages, with an IC50 value of 12.6 μM[4]. Cyclobenzaprine (0-50 μM, 6 h) induces oxidative stress in Leishmania infantum in a concentration- and time-dependent manner[4].

Animal Model:Leishmania infantum-infected BALB/c mice model[3]
-
Dosage:12.32, 24.64 and 49.28 mg/kg
-
Administration:Oral gavage (i.g.), once daily for 5 days
-
Result:Was effective in reducing the parasite load by 40.4% and 66.7% in spleen at 24.64 and 49.28 mg/kg, respectively and by 85.6% and 89.3% in liver at 24.64 and 49.28 mg/kg.
-
Animal Model:Spinalized Male Wistar rats; Non-spinalized/Intact Male Wistar rats [5]
-
Dosage:0.3, 1.0, 3.0 mg/kg
-
Administration:Intravenous injection (i.v.), single dose
-
Result:Dose-dependently reduced the monosynaptic reflex amplitude in non-spinalized rats, whereas it did not change the monosynaptic reflex amplitude in spinalized rats. Significantly inhibited the effect of the 5-HT2 receptor agonist DOI at the dose of 1 mg/kg, which had significantly increased the monosynaptic reflex in spinalized rats at 5 minutes.
