体内活性
L-765314 shows weak potency for inhibiting the pressor response to either phenylephrine or A-61603 (AD25>3 mg/kg for each).?On the basis of the inhibition of pressor responses to the R1a subtype selective agonist A-61603, L-765314 appears to be selective versus the R1a receptor up to a dose of 0.3 mg/kg.?The results of hypotensive potency in rats show that both L-765314 and terazosin tend to decrease heart rate (about 25 bpm at 1 mg/kg iv)[1]
