Three, result and conclusion
1, MTT experiment result
All occur obvious cell inhibitory effect effect after the compound (I) of different concns acts on people's adenocarcinoma ovaries SKOV3 cell 24,48 and 72h, show as OD value (absorbance A570) and reduce, inhibiting rate raises; Result between different concns group is variant, and difference has statistical significance (P<0.05), also significant difference (P<0.05) is had different action time, show that compound (I) propagation to ovarian cancer SKOV3 cell is inhibited, and its inhibiting rate is concentration and time-dependent manner.Learnt by experimental result, when concentration is 20 μm of ol/L, effect is more satisfactory.The results are shown in Table 1.
2, PI staining flow cytometry (FCM) detects the result of cell cycle
The compound (I) choosing different concns (10,20,30 μm of ol/L) acts on SKOV348h, and experimental group comparatively control group compares G
0/ G
1cell quantity in increasing trend, and S phase and G
2/ M cell quantity is minimizing trend, and when being 20 μm of ol/L with compound (I) concentration, effect is the most obvious.Compared with control group, each experimental group has statistical significance (P<0.05).G after each experimental group effect 48h
0/ G
1cell quantity be respectively 10 μm of ol/L groups (60.707 ± 2.382), 20 μm of ol/L groups (69.611 ± 2.366), 30 μm of ol/L groups (61.099 ± 1.577), the analysis showed that 30 μm of ol/L groups are compared with 10 μm of ol/L, no significant difference (P=0.809), comparing difference between all the other each concentration groups all has statistical significance (P<0.05).After each experimental group effect 48h, the cell quantity of S phase is respectively l0 μm of ol/L group (24.254 ± 3.244), 20 μm of ol/L groups (19.468 ± 0.580), 30 μm of ol/L groups (17.743 ± 1.311), wherein 30 μm of ol/L groups are compared with 20 μm of ol/L groups, no significant difference (P=0.305), all the other each concentration groups compare difference statistical significance (P<0.05).G after each experimental group effect 48h
2the cell quantity of/M phase is respectively l0 μm of ol/L group (13.276 ± 0.658), 20 μm of ol/L groups (10.624 ± 0.483), 30 μm of ol/L (21.147 ± 2.865), and comparing difference between remaining each concentration group has statistical significance (P<0.05).It can thus be appreciated that the effect that the compound of 20 μm of ol/L (I) acts on SKOV348h is best, by cell-cycle arrest in G
0/ G
1phase, make it can not enter the S phase.The results are shown in Table 2 (note: compared with control group, equal P<0.05; * G
0/ G
1during the phase, 30 μm of ol/L groups are compared with 10 μm of ol/L groups, no significant difference (P=0.809), and during S phase, 30 μm of ol/L are compared with 20 μm of ol/L, no significant difference (P=0.305); All the other G
0/ G
1, S, G
