nocifensive

PF4840154 是有效的大鼠和人TrpA1通道选择性激动剂，EC50分别为 97 和 23 nM。PF-4840154 可以诱导 TrpA1 介导的小鼠伤害行为。

CAY10787 is an oxysterol and a negative allosteric modulator of GABAAreceptors.1,2It reduces GABA-induced currents in HEK cells expressing α1β1γ2or α4β3γ2subunit-containing GABAAreceptors (IC50s = 1.5 and 1 μM, respectively).2CAY10787 (500 nM) reduces GABA-induced depolarization of peptidergic and non-peptidergic nociceptors, C-LTMRs, and cold thermosensors in isolated mouse dorsal root ganglion (DRG) neurons.In vivo, CAY10787 (2, 10, and 50 mg/kg) increases latency to nocifensive behaviors in the hot plate test in mice. 1.Hahn, M., Tang, M., and Subbiah, M.T.Cholest-3,5-dien-7-one formation in peroxidized human plasma as an indicator of lipoprotein cholesterol peroxidation potentialBiochim.

Tat-AKAP79 (326-336) 是一种肽，由HIV-1 Tat蛋白质转导域与对应于A-kinase anchor protein 79 (AKAP79) 326至336残基的11个氨基酸肽链相连组成。在200 µM浓度下，能抑制蛋白激酶A (PKA) 或PKC激活诱导的瞬时受体电位钒通道1 (TRPV1) 在分离的大鼠背根神经节 (DRG) 神经元中的敏感化。在体内，Tat-AKAP79 (326-336) 抑制小鼠由甲醛或phorbol 12-myristate 13-acetate (PMA014) 引发的伤害性行为。它还延长了小鼠对辐射热刺激爪子撤回的潜伏期，并在卡拉胶诱导的炎症性疼痛小鼠模型中增加了爪子撤回的机械阈力。
