SB 258719

Research use only, not for human use.

SB 258719 is a selective antagonist of 5-HT7 receptor with pKi of 7.5.

SB 258719 is a selective antagonist of 5-HT7 receptor with pKi of 7.5.(In Vitro):SB 258719 antagonised surmountably 5-CT-stimulated adenylyl cyclase activity. Schild analysis of the antagonism by SB 258719 gave a pA2?of 7.2±0.2 and slope not significantly different from 1, consistent with competitive antagonism.(In Vivo):SB 258719 (5-20 mg/kg, i.p.) reversed the hypothermic effect of 5-CT in mice. Increased Wnt/β-catenin activity was attenuated by SB 258719 in HCC cell lines and patient-derived primary tumour tissues in the presence of 5-HT. SB 258719 also reduced tumour growth in vivo.

SB 258719 (1, 3 and 10 μM; HEK 293 cells) produces a concentration-related rightward-shift of the 5-CT concentration-response curve with no signifcant alteration in the maximal response to 5-CT.

SB 258719 (5-20 mg/kg; i.p.) significantly attenuates the 5-CT-induced hypothermia. Animal Model:Male Swiss Webster mice (20-25 g).Dosage:5-20 mg/kg Administration:I.p.Result:Significantly attenuated the 5-CT-induced hypothermia.
