体内研究 (In Vivo) | MDR-652 (0.5 and 5 mg/kg) displays a dose-dependent decrease of body temperature, supporting that MDR-652 displays TRPV1 agonism in the intact animal[1]. MDR-652 (5-10 mg/kg; i.p. and s.c.) blocks the neuropathic pain completely, indicating 100% maximum possible effect (MPE)[1]. MDR-652 has a promising topical pharmacokinetic profile[1]. MDR-652 has no significant toxicity. In a single-dose toxicity study, the LD50of MDR-652 is higher than 200 and 2000 mg/kg in i.p. and p.o. administration, respectively[1].
Animal Model: | ICR mouse[1] | Dosage: | 0.5 and 5 mg/kg | Administration: | Administered intraperitoneally; 7 hours | Result: | Decreased body temperature in a dose-dependent manner. |
Animal Model: | Rats with spinal nerve ligation (SNL) model[1] | Dosage: | 1, 2, 5, and 10 mg/kg | Administration: | Administered intraperitoneally and subcutaneously; 24 hours | Result: | The i.p. administration exhibited an excellent and dose dependent analgesic profile with an ED50of 0.5-2 mg/kg. The subcutaneous injection (sc) also displayed an excellent analgesic outcome with maximum effect at 30 min after administration. |
