SB269970 HCl is a potent and selective 5-HT7 receptor antagonist, with a high affinity (pKi = 8.9) [1]. SB269970 HCl can cross the blood-brain barrier and is widely used in neuroscience research to study the role of the 5-HT7 receptor in a variety of central nervous system functions[2]. SB269970 HCl is employed in pharmacological studies to explore its potential therapeutic applications in conditions such as depression, anxiety, and sleep disorders[3].
SB269970 HCl (1µM; 24h) treatment can inhibit proliferation in PC-3 cells and is associated with an apoptosis-inducing effect[4]. SB269970 HCl combined with MSX3 and ketanserin treatment can suppress pAKT expression in neuroblastoma cell lines over the long term[5].
SB269970 HCl (1mg/kg) exerted a specific antianxiety-like effect in the Vogel drinking test and elevated plus-maze test in rats[6]. SB269970 HCl (10 and 30mg/kg) significantly attenuated amphetamine-induced rearing and circling in rats[7].
