实验参考方法

Cell experiment:

Neuronal nuclear antigen (NeuN)-positive neurons and some astroglia are derived from mechanically dissociated ganglionic eminences of E16 rat embryos. The HD model is based on the expression of mutant huntingtin. Treatments of cultures with AK-7 are at 10 μM for 24 h unless stated otherwise. DMSO is included at the same concentrations as a control. Lower dose, chronic treatments with AK-7 are introduced to neurons at DIV4 and continued weekly coinciding with normal medium change[1].

Animal experiment:

AK-7, solubilized at 1.5 mg/mL in 25% Cremophor EL (BASF)/ 10% DMSO in water, is administered by intraperitoneal injection to 11 week old mice at 15 mg/kg/dose, and compound levels in serum and brain are measured following sacrifice. Blood is collected and centrifuged at 7,000 rpm for 7 min, and then serum is aspirated and immediately frozen in liquid nitrogen. Brains are immediately frozen in liquid nitrogen and stored at −80°C. Brains are weighed and then homogenized in four volumes of 10% Cremophor RH40 in water using a Polytron homogenizer, and 2% v/v phosphoric acid is added to the homogenate, vortexed, and centrifuged at 10,000 g at 25°C for 1 h. The supernatant is aspirated, and solid phase extraction is performed immediately. Serum samples are vortexed into 2% v/v phosphoric acid and centrifuged at 2500 rpm for 10 min[1].

产品描述

AK-7 is a selective cell- and brain-permeable SIRT2 inhibitor, with an IC50 of 15.5 μM.

AK-7 (10 μM) reduces cholesterol levels in naive N2a neuroblastoma cells and hippocampal slice cultures from wild-type mice. AK-7 (1 μM) shows neuroprotective effect of AK-7 in striatal Huntington’s disease (HD) neurons[1]. AK-7 (12.5 μM) decreases ratio of DA neurons in primary midbrain cultures[3].

AK-7 (15 mg/kg/dose, i.p.) is brain-permeable in wild-type and HD mice[1]. AK-7 (10, 20 mg/kg, i.p.) improves the behavior and neuropathological phenotype and extends survival of R6/2 HD mice. AK-7 (20 mg/kg) ameliorates HD neuropathology in R6/2 mice. AK-7 also reduces the polyglutamine aggregation in R6/2 brain. In addition, AK-7 treated 140CAG mice show motor performance changes that parallel untreated wild-type mice, with the 20 mg/kg dose being most effective and significantly different from untreated 140CAG mice[2].
