Biological Activity

HS-173 inhibited the PI3K signaling pathway, and showed anti-proliferative effects on cancer cells. Also, HS-173 induced cell cycle arrest at the G(2)/M phase and apoptosis. In addition, HS-173 decreased the expression HIF-1α and VEGF which play an important role in angiogenesis. Furthermore, HS-173 diminished blood vessel formation in the Matrigel plug assay in mice. Combined treatment of Sorafenib and HS-173 synergistically inhibited the viability of Panc-1 cells (combination index<1). HS-173 demonstrated anti-proliferative effects in NSCLC cells and effectively inhibited the PI3K signaling pathway in a dose‑dependent manner.HS-173 reduced the expression of α-smooth muscle actin (α-SMA), vimentin, PAI-1, fibronectin, collagen type I, collagen IV and TGF-β-activated smad2/3 in PD-derived primary fibroblasts.

Protocol
Cell Experiment
Cell lines T47D, SK-BR3, MCF7 cells
Preparation method Using a MTT assay to performe cell viability . Briefly, plating T47D cells in 96-well plates for 24 h. Then,removing the medium and treating cells with either DMSO as a control or various concentrations of inhibitors. The final concentration of DMSO in the medium was ≤0.1% (v/v). After incubating the cells for 48 h, adding 20 μL MTT solution (5 mg/mL) to each well for another 4 h at 37 °C. The formazan crystals that formed are dissolved in DMSO (100 μL/well) by constant shaking for 5 min. Then read the plate on a microplate reader at 540 nm. Three replicate wells are used for each analysis. The median inhibitory concentration (IC50, defined as the drug concentration at which cell growth is inhibited by 50%) is assessed from the dose−response curves. To assess the effect of compounds on cell proliferation, culturing T47D cells with compound (0.1−100 μM) for 48 h before MTT analysis.
Concentrations ~50 μM
Incubation time 48 hours
Animal Experiment
Animal models Male BALB/c mice with CCl4-induced liver fibrosis
Formulation Dissolved in DMSO, and then mixture (DMSO:PEG400:D.W. = 1:5:4).
Dosages ~20 mg/kg

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
