Description

A66 is a highly specific and selective p110α inhibitor with an IC50 value of 32nM[1, 2]. A66 can also inhibit p110α mutation such as p110α E545K and p110α H1047R, which have the IC50 values of 30nM and 43nM[1]. A66 can inhibit tumor necrosis factor induced necroptosis[3].

A66 (100nM; 24h) markedly opposed the increased expression of Ido1 and Tgfb1 transcripts by TGF-β in mouse plasmacytoid dendritic cells[4]. A66 (100nM; 1h) reduced lipid kinase activity in MT (polyoma middle T antigen) tumor cells[5]. A66 (100nM; 1h) significantly inhibited the phosphorylation of Akt in human rhabdomyosarcoma Rh30 cells tranfected p110 retrovirus[6].

A66 (10mg/kg; i.p. ; 24h) induced an increase in glucose production during a pyruvate (2g/kg; i.p. ) tolerance test in mice[7]. A66 (10mg/kg; i.p. ; 21 day) significant delayed in growth of SK-OV-3 cells derived xenograft tumours in mice xenograft model (SK-OV-3 cells were subcutaneously inoculated on the right flank of the mice)[1].

Protocol

Cell experiment [1]:

Cell lines

Human rhabdomyosarcoma Rh30 cell line

Preparation Method

Human rhabdomyosarcoma Rh30 cells were maintained in RPMI-1640 medium supplemented with 10% fetal bovine serum. Myristoylated tag was ligated in tandem with each p110 gene sequences and then inserted into pBabe-Puro plasmid. The resulting constructs were co-transfected with pGP and pE-Ampho plasmids into 293FT cells to obtain retrovirus, which were then used to infect Rh30 cells. After selection with 1μg/mL puromycin for 1 week, cells stably expressing myristoylated PI3K isoforms were pooled for validation and named as Rh30-Myr-p110. Rh30-Myr-p110 cells grown to 50% confluence in 12-well plates continued to be incubated in serum-free medium for 12h and were then exposed to A66 at 100nM for 1h.

Reaction Conditions

100nM; 1h

Applications

A66 significantly inhibited the phosphorylation of Akt in human rhabdomyosarcoma Rh30-Myr-p110 cells.
Animal experiment [2]:

Animal models

Male CD1 mice

Preparation Method

For glucose tolerance tests and pyruvate tolerance tests the mice were starved overnight and for the insulin tolerance test food was withdrawn 2h prior to the start of the experiments. A66 was dosed intraperitoneally 1h after the end of the dark cycle and 1h prior to the intraperitoneal dosing with glucose or pyruvate (2g/kg) or insulin (0.75unit/kg).

Dosage form

10mg/kg; 24h; i.p. 

Applications

A66 induced significant impairments in the insulin tolerance test and glucose tolerance test, and an increase in glucose production during a pyruvate tolerance test in mice.
