JYL 1421

Research use only, not for human use.

JYL 1421 is an antagonist of TRPV1 receptor (IC50 = 8 nM).

JYL 1421 is an antagonist of TRPV1 receptor (IC50 = 8 nM).(In Vitro):JYL 1421(5 min) inhibits the capsaicin (330 nM)-evoked Ca2+ accumulation in a concentration-dependent manner. The inhibitory effect of the lowest concentration (5 nM) of JYL 1421 reaches the level of significance and 1 μM almost abolishes the response, only 3.1±0.65% of the first capsaicin-induced Ca2+ influx could be observed.(In Vivo):1 and 2 μg/kg capsaicin i.v. injection evokes a transient drop of blood pressure by 47.4±4.7 and 59.6±4.2 Hgmm (n=6), respectively. Both applied doses of JYL 1421 (0.4 and 1.6 mg/kg) fail to evoke hypotension. JYL 1421 inhibits the capsaicin-induced fall in blood pressure in a dose-dependent manner as shown by the need for higher capsaicin doses to elicit the reflex hypotension after JYL 1421 administration than before treatment. Capsazepine fails to induce a significant inhibition of the capsaicin-evoked hypotension up to a dose of 2 mg/kg. Instillation of capsaicin solution (50 μL, 10 μg/mL) into the left eye of the rat evokes 12.9±1.3 wiping movements within 3 min. Pretreating the rats with JYL 1421(0.4 or 1 mg/kg i.p.) does not influence significantly the wiping behavior, but 2-5 mg/kg JYL 1421 reduces the number of wiping movements in a dose-dependent manner with an ID50 value of 4.6 mg/kg. The mean arterial pressure of untreated rats is 109.9±4.2 Hgmm (n=6).

Incubation with JYL 1421 for 5 min concentration-dependently inhibits the capsaicin (330 nM)-evoked Ca2+ accumulation. The inhibitory effect of the lowest concentration (5 nM) of JYL 1421 reaches the level of significance and 1 μM almost abolishes the response, only 3.1±0.65% of the first capsaicin-induced Ca2+ influx could be observed. The IC50 value is 8 nM for JYL 1421. Meanwhile, the effect of capsazepine is markedly smaller, it induces 41.7% inhibition in 1 μM concentration, but this inhibitory effect does not increase further in 10 μM and does not reach 50%.

Instillation of 50 μL capsaicin solution (10 μg/mL) into the left eye of the rat evokes 12.9±1.3 wiping movements within 3 min. Pretreating the rats with 0.4 or 1 mg/kg i.p. JYL 1421 does not influence significantly the wiping behavior, but 2-5 mg/kg dose-dependently reduces the number of wiping movements. The ID50 value is 4.6 mg/kg. The mean arterial pressure of untreated rats is 109.9±4.2 Hgmm (n=6). One and 2 μg/kg capsaicin i.v. injection evokes a transient drop of blood pressure by 47.4±4.7 and 59.6±4.2 Hgmm (n=6), respectively. Both applied doses of JYL 1421 (0.4 and 1.6 mg/kg) fail to evoke hypotension. JYL 1421 dose-dependently inhibits the capsaicin-induced fall in blood pressure as shown by the need for higher capsaicin doses to elicit the reflex hypotension after JYL 1421 administration than before treatment. Capsazepine fails to induce a significant inhibition of the capsaicin-evoked hypotension up to a dose of 2 mg/kg.
