SB269970 HCl 화학적 특성, 용도, 생산

• 개요

  The transduction of neurobehavioral effects by serotonin (5-hydroxy tryptamine; 5-HT) is mediated by at least seven major 5-HT receptor subtypes. SB-269970 is a potent 5-HT_7A antagonist (pK_i = 8.9) that demonstrates >50-fold binding selectivity over 5-HT_5A and >250-fold selectivity over 5-HT₁, 5-HT₂, 5-HT₄, 5-HT₆, adrenergic α₁, dopamine D₂, and dopamine D₃ receptors. It is also reported to block adrenergic α₂ receptors in guinea pig vas deferens. SB-269970 has been used to target the 5-HT₇ receptor in the study of schizophrenia-like cognitive deficits.

• 용도

  SB 269970A is a selective 5-HT7 receptor antagonist.

• 일반 설명

  A selective 5-HT₇ receptor antagonist. Extremely potent in vivo and in vitro. Chronic or acute (even single dose) administration of SB269970 induces functional desensitization of the 5-HT₇ receptor system, which precedes changes in the receptor density. This mechanism may be responsible for the rapid antidepressant-like effect of the 5-HT₇ antagonist in animal models. SB-269970 is an analogue of SB-258719 and has been shown to have at least 100 fold selectivity versus all other 5-HT receptor subtypes except the human 5-HT_5A receptor (pKi values are 8.9, 7.2 and 6.0 for 5-HT_7A, 5-HT_5A and 5-HT_1B).
