UCL 2077
Based on 1 Customer Validation
UCL 2077 is a potassium channel and slow afterhyperpolarization (sAHP) inhibitor. UCL 2077 selectively blocks sAHP channels without affecting L-type Ca2+ currents. UCL 2077 blocks KCNQ1- and KCNQ2-containing K+ channels, decreases erg current amplitude, increases erg deactivation rate. UCL 2077 can be used for the research of hippocampus-dependent memory retrieval deficit and cardiac arrhythmias.

生物活性
UCL 2077 potently and selectively blocks the sAHP in cultured rat hippocampal pyramidal neurons with an IC50 of 0.5 μM[1].
UCL 2077 (0.1-100 µM) potently inhibits erg-mediated potassium current in pituitary GH3 cells with an IC50 of 4.7 µM and Kd of 5.1 µM[2].
UCL 2077 (30 µM) significantly reduces both activation (za) and deactivation (z(deact)) gating charges of IK(erg) in pituitary GH3 cells[2].
UCL 2077 (3-30 µM) concentration-dependently reduces the voltage hysteresis of IK(erg) in pituitary GH3 cells, with 10 µM decreasing the hysteresis area by approximately 50%[2].
UCL 2077 (1-100 µM) inhibits delayed-rectifier potassium current (Ik(DR)) in pituitary GH3 cells with an IC50 of 13.4 µM[2].
UCL 2077 (3-30 µM) concentration-dependently reduces the open probability of IKca channels in pituitary GH3 cells without altering single-channel amplitude, and this suppression is reversed by 9-Phenanthrol (HY-108457)[2].
UCL 2077 (3-10 µM) concentration-dependently increases spontaneous action current frequency in pituitary GH3 cells, and this effect is abolished by KCNH2 siRNA knockdown, indicating dependence on erg potassium channels[2].

UCL 2077 (2 μg/dorsal hippocampus; central infusion into dorsal hippocampus; single dose) fully rescues contextual fear memory retrieval in β1-adrenergic receptor-deficient β1 KO mice without altering non-specific freezing behavior[1].

Animal Model:hybrid 129/Sv × C57BL/6 (Dbh-/-, norepinephrine/epinephrine-deficient, 3-5 months old, both sexes)[1]
-
Dosage:0.5 μg/dorsal hippocampus; 1 μg/dorsal hippocampus; 2 μg/dorsal hippocampus
-
Administration:central infusion into dorsal hippocampus; single dose
-
Result:Significantly increased freezing percentage relative to vehicle at 0.5 μg/dorsal hippocampus (p < 0.05).
Produced further significant increases in freezing percentage at 1 μg/dorsal hippocampus and 2 μg/dorsal hippocampus (p < 0.001).
Rescued contextual fear memory retrieval in a dose-dependent manner with an estimated ED50 of 0.5 μg/dorsal hippocampus.

Administration:central infusion into dorsal hippocampus; single dose
-
Result:Fully rescued contextual freezing behavior in β1 KO mice (p < 0.0002), restoring freezing to levels comparable to wild-type mice.
Had no effect on freezing in pseudo-conditioned β1 KO mice (p = 0.71), indicating no non-specific enhancement of fear or freezing.
