4-氟-N-(3-(1-甲基哌啶-4-基)-1H-吲哚-5-基)苯甲酰胺盐酸盐

LY334370 has no vasoconstrictor effects on human cerebral arteries in vitro until a dose of 10 ^-5 M, at which it produces a contraction of 8.5±5.7%; however, this is not significant.

Following intravenous administration of LY334370 at 3 mg/kg (n=3) or 10 mg/kg (n=6) electrical stimulation evokes an increase in dural blood vessel diameter of 135±6% and 106±11%, respectively, which is not significantly different from the respective control values. LY334370 has no effect on dural blood vessel diameter per se , since the actual dural blood vessel diameter is 43±4 arbitrary units before drug and 43±4 arbitrary units 15 min after injection of LY334370 (10 mg/kg).
