title: Cellular effects induced by some synthetic prostaglandins obtained at ICCF-Bucharest.
abstract: Four prostaglandin compounds synthetized at ICCF [chloprostenol triacetate (a), the isopropylic ester of the chloprostenol analogue (b), a PGA2 sulprostone analogue (c) and a PGE2 analogue (d)] were tested with respect to the cytotoxic effect, by successive studies on chicken embryo fibroblasts (CEF) and on human cells (HeLa). It was established that (b) and (d) display a high cytotoxicity, while (a) and (c) were relatively well tolerated by the cell layer. The spectrofluorometric determinations showed that these drugs did not induce modifications at the cell membrane level. The treatment with 4 micrograms/ml PGs (a) and (c) of HeLa cells inoculated with Sendai virus produced a significant decrease of TCID50/ml 24 hrs after drug introduction into the culture medium, from 10(6.5) to 10(4.5) and to 10(3.25), respectively.
