The present work evaluated the cytotoxicity of piplartine {5,6-dihydro-1-[1-oxo-3-(3,4,5- trimethoxyphenyl)-trans-2-propenyl]-2(1H)pyridinone} and piperine {1-[5-(1,3)-benzodioxol- 5-yl)-1-oxo-2,4-pentadienyl]piperidine}, components obtained from Piper species. The substances were tested for their cytotoxicity on the brine shrimp lethality assay, sea urchin eggs development, 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay using tumor cell lines and lytic activity on mouse erythrocytes. Piperine showed higher toxicity in brine shrimp (DL50 = 2.8 d 0.3 μg/ml) than piplartine (DL50 = 32.3 d 3.4 μg/ml). Both piplartine and piperine inhibited the sea urchin eggs development during all phases examined, first and third cleavage and blastulae, but in this assay piplartine was more potent than piperine. In the MTT assay, piplartine was the most active with IC50 values in the range of 0.7 to 1.7 μg/ml. None of the tested substances induced hemolysis of mouse erythrocytes, suggesting that the cytotoxicity of piplartine and piperine was not related to membrane damage.

Six new dammarane-type saponins, gypenosides CP1-6 (16), along with 19 known compounds 7–25, were isolated and characterized from the aerial parts of Gynostemma pentaphyllum. Among these compounds, eight dammarane-type saponins, 2, 5, 6, 7, 11, 12, 13, and 15, exhibited the greatest antiproliferative effects against two human tumor cell lines (A549 and HepG2).

SummaryThis paper reports studies on the interaction between human platelets, the plasma coagulation system, and two human tumor cell lines grown in tissue culture: Melanoma and breast adenocarcinoma. The interaction was monitored through the use of 125I- labelled fibrinogen, which measures both thrombin activity generated by cell-plasma interaction and fibrin/fibrinogen binding to platelets and tumor cells. Each tumor cell line activates both the platelets and the coagulation system simultaneously resulting in the generation of thrombin or thrombin-like activity. The melanoma cells activate the coagulation system through “the extrinsic pathway” with a tissue factor-like effect on factor VII, but the breast tumor seems to activate factor X directly. Both tumor cell lines activate platelets to “make available” a platelet- derived procoagulant material necessary for the conversion of prothrombin to thrombin. The tumor-derived procoagulant activity and the platelet aggregating potential of cells do not seem to be inter-related, and they are not specific to malignant cells.
