Abstract

To synthesize 3, 5, 4' -trimethoxystilbene (TMS) by methylation of resveratrol (Res), a natural compound extracted from polygonum cuspidatum, to identify the chemical structure of TMS, to test its pharmacokinetics, and to determine the effects of TMS on the growth inhibition and apoptosis in pulmonary artery smooth muscle cells (PASMCs). The chemical structure of TMS was analyzed by UV- and IR- absorption spectrometry, (1)H-NMR and (13)C-NMR spectroscopy and mass spectrometry. We measured the bioavailability, the characteristics of intestinal absorption, and the distribution of TMS in body and excretions of SD rats after oral administration of TMS. The acute toxicity of TMS in mice was tested. PASMCs were prepared from pulmonary artery of SD rats. The PASMCs were divided into 8 groups. Group of A (control) was cultured without TNF-α, TMS, or Res. Group of B (TNF-α) was cultured with 100 pg/mL TNF-α. Groups of C-E (low-high concentrations of TMS) were cultured with 100 pg/mL TNF-α and 5, 10, 20 μmol/L TMS, respectively. Groups of F-H (low-high concentrations of Res) were cultured with 100 pg/mL TNF-α and 50, 100, 200 μmol/L Res, respectively. The proliferation of PASMCs after treatment was determined by MTT assay. The apoptosis ...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
