Biological Activity

Description

SAFit2, a chemical probe, is a highly potent, highly selective FK506-binding protein 51 (FKBP51) inhibitor with a K_i of 6 nM and also enhances AKT2-AS160 binding^[1].

IC₅₀ & Target

Ki: 6 nM (FKBP51)^[1]

In Vitro

SAFit2 treatment increases the expression of pAKT2 (soleus and EDL muscle) and pAS160 (EDL muscle) in WT cells, but there is no effect of FKBP51 antagonism in 51KO cells. Moreover, following SAFit2 treatment, GLUT4 expression increases in the membrane fraction of primary EDL myotubes from WT mice, but not from 51KO mice^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

It is found that 30 days of SAFit2 administration leads to a reduction in body weight under both control and high-fat diet (HFD) conditions. SAFit2 significantly increases phosphorylated AKT2 and AS160 in EDL muscle and likewise increases expression of GLUT4 at the membrane in soleus muscle^[2]. When SAFit2 is applied 1 h before testing, no alterations in anxiety-related behavior are observed. However, SAFit2 treatment induces an anxiolytic phenotype in mice injected 16 h prior testing, which is reflected in a significantly increased open arm time in the elevated plus maze (EPM) (z=-2.183, p<0.05). SAFit2 treatment leads to a significantly reduced latency to enter the lit compartment (z=-2 to 265, p<0.05), as well as a significantly increased distance traveled (t₍₂₀₎=-2.371, p<0.05) in the lit compartment^[3].

Protocol

Cell Assay^[2]

Primary EDL myotubes are exposed to 0.6 µM SAFit2 or DMSO (vehicle) overnight. The following day, cells are serum-starved in low glucose (1000 mg/L) DMEM for 4 h with SAFit2 or DMSO, and are subsequently collected for the rapid preparation of the plasma membrane fraction. The membrane fraction is used in subsequent Western blot assays for the detection of GLUT4^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration^[3]

Male C57BL/6N mice at the age of 12 to 15 weeks are used. The mice are held under standard conditions (12 h light/dark cycle, lights on at 08:00 A.M.; temperature 23±2°C), are single housed and acclimatized to the room for 2 weeks before the commencing experiments. Food and tap water are available ad libitum. Animals receive a bilateral microinjection into the basolateral amygdala (BLA) (0.5 μL per side) of vehicle or SAFit2 (20 mg/kg BW) 16 h before the start of the test. The effects on anxiety-related behavior is analyzed (n=14 per group) 16 h after the application^[3].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
