aucubin/leukemia

Antigen (Ag)-stimulated mast cells induce synthesis and production of cytokines including tumor necrosis factor (TNF)-alpha and interleukin (IL)-6 with proinflammatory and immune regulatory properties. Expression of TNF-alpha and IL-6 was regulated by a transcription factor, nuclear factor

The novel iridoid glycoside 2 was prepared in six steps (15% overall yield) from natural aucubin (1) and fully characterized. Compound 2, which comprises the same conjugated cyclopentenone pharmacophore as known antitumor oxylipins and prostaglandins, displayed significant antiproliferative in vitro

Several studies have demonstrated that deregulated activation of signal transducer and activator of transcription 3 (STAT3) has been associated with survival, proliferation, chemoresistance and angiogenesis of tumour cells. Thus, inhibition of STAT3 expression could be a potent therapeutic approach

The aim of the present study was to evaluate the antileukemic activity of six chemical classes of pure compounds present in commonly used medicinal plants in Taiwan--such as the genus Plantago. Studies were conducted on a series of human leukemia and lymphoma cell lines. Results showed that water
