生物活性

Orexin B, human (TFA) is an endogenous agonist at Orexin receptor with K_is of 420 and 36 nM for OX1 and OX2, respectively.

IC₅₀&Target

Ki: 420 nM (OX1), 36 nM (OX2).

体外研究

Orexin B is derived by proteolytic amino acid precursor, prepro-orexin, which is encoded by a gene localized to chromosome 17q21 in humans. In radioligand binding studies, Orexin B has a higher affinity for the OX2 receptor.
Human Orexin B has two amino acid substitutions when compared with the rodent sequence. OX2 receptor is indeed a high-affinity receptor for human orexin B, with an IC₅₀ of 36 nM in the binding assay and an EC₅₀ of 60 nM in the [Ca]i transient assay. Human Orexin B has significantly lower affinity for the human OX1: the calculated IC₅₀ in the competitive binding assay and the EC₅₀ in the [Ca]i transient assay are 420 nM and 2500 nM for human orexin-B, respectively.

体内研究

Human Orexin B significantly augments food intake; at the 2 hr time point, 5- and 12-fold stimulation of food consumption is observed by 3 nM and 30 nM orexin-B, respectively.

Animal Model:	Male Wistar rats (180-200 g).
Dosage:	3 nM and 30 nM.
Administration:	Administered in a 5 mL bolus through a catheter placed in the left lateral ventricle in early light phase.
Result:	Significantly augmented food intake.

工作液浓度： mg/ml；

DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，注：如该浓度超过该批次药物DMSO溶解度，请先联系客服）；

体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL ddH₂O，混匀澄清。

配置后的溶液总体积：

注意：1. 首先保证母液是澄清的；
2. 一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
