HY-107664

*SR 142948*	Neurotensin Receptor	Neurological Disease
SR 142948 is an orally active and selective non-peptide neurotensin receptor (NT) antagonist with IC₅₀s of 1.19 nM, 0.32 nM, 3.96 nM in h-NTR1-CHO cells, HT-29 cells, and adult rat brain, respectively. SR 142948 antagonizes NT-induced inositol monophosphate formation in HT-29 cells with an IC50 of 3.9 nM. SR 142948 blocks hypothermia, analgesia and steering behavior induced by NT in vivo. SR 142948 shows blood-brain permeability and can be used in study of psychiatric disorders .

HY-124767

SR 142948A	Neuropeptide Y Receptor	Neurological Disease
SR 142948A is a non-peptide neuropeptide neuropeptin (NT) receptor antagonist. SR 142948A is able to bind to neuropeptin receptors, especially with high affinity for NT1 and NT2 receptors. SR 142948A is mainly used to study the role of neuropeptide in the neurotransmitter system, especially the dopamine system .

Western blot analysis of extracts from THP-1(lane 2(20μg), Jurkat (lane 3(20μg) and NIH3T3(lane 4(20μg) using FOXO1A (HY-P80132) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
