Six previously undescribed uncommon ester-bonded dimeric compounds (aquilacrassnins A–F) containing a sesquiterpenoid and a 5,6,7,8-tetrahydroxy-2-(2-phenylethyl)-5,6,7,8-tetrahydro -4H-chromone units were isolated from the EtOAc extract of agarwood originating from Aquilaria crassna. Their structures were elucidated by spectroscopic (NMR, UV, IR, MS, and ECD) methods. All the compounds were tested...
Objective To evaluate effects of different factors on proliferation capacity and cytotoxicity of induced cytokine induced killer (CIK) cells in vitro, so as to provide experimental basis for cell therapy of CIK in tumor. Methods Cytometry and MTT assay were used in detecting proliferation capacity and cytotoxicity of CIK. Results The proliferation capacity and cytotoxicity of CIK in vitro were...
