CH 275 is a peptide analog of somatostatin and binds preferably to somatostatin receptor 1 (sst1) with a Ki of 52 nM. CH 275 acts as a potent and selective sst1 agonist (IC50=30.9 nM) and also displays IC50 values of 345 nM, >1 μM, >10 μM, >10 μM for human sst3, sst4, sst2 and sst5, respectively. CH 275 can be used for the research of alzheimer’s disease.

Description

CH 275 is a peptide analog of somatostatin and binds preferably to somatostatin receptor 1 (sst1) with a Ki of 52 nM[1]. CH 275 acts as a potent and selective sst1 agonist (IC50=30.9 nM) and also displays IC50 values of 345 nM, >1 μM, >10 μM, >10 μM for human sst3, sst4, sst2 and sst5, respectively[2]. CH 275 can be used for the research of alzheimer’s disease[3].

IC50 & Target

SSTR1

 

In Vitro

CH275 (100 nM) activates neprilysin activity, wheras treatment with cyclo-SRIF can complete this activation in vitro in primary neuron-based cell culture system, a mixture of wildtype hippocampal, cortical and striatal neuron[3].

In Vivo

CH275 (osmotic pump administration; 56 μM; two weeks) decreases the level of neprilysin/SRIF in the App knock-in mice[3].
CH275 directly injects into the Lacunosum molecular layer (Lmol) layer of 2-month-old AppNL-G-F mice for four months. AppNL-G-F mice begin to exhibit Aβ plaques at two months of age, but CH275 leads to robustly increased the expression of neprilysin in hippocampus which is paralleled by a clear reduction in Aβ plaque load in the same region, and without causing any toxic side effects[3].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
