Design, synthesis and antiproliferative activity studies of novel dithiocarbamate-chalcone derivates.

A series of novel dithiocarbamate-chalcone derivates were designed, synthesized and evaluated for antiproliferative activity against three selected cancer cell lines (EC-109, SK-N-SH and MGC-803). Majority of the synthesized compounds exhibited moderate to potent activity against all the cancer cell lines assayed. Particularly, compounds II2 and II5 exhibited the excellent growth inhibition against SK-N-SH with IC50 values of 2.

[Effects of electromagnetic pulse exposure on the permeability of inner blood-retinal barrier model in vitro].

Objective: To establish the inner blood-retinal barrier (BRB) model in vitro by co-culturing RF/6A cells and C6 cells and to investigate the effects of EMP (200 kV/m, 200 pulses) exposure on the permeability of the inner BRB model in vitro.

Methods: RF/6A cells and C6 cells were co-cultured on transwell, and the characteristic of the inner BRB model was assessed by detecting transendothelial electrical resistance (TEER) and the permeability of horseradish peroxidase (HRP). The co-cultured model was exposed or sham exposed to the EMP (200 kV/m 200 pulses) for 0.
