		        	Abstract:
			       	
			       		
				        
				        	OBJECTIVE:To investigate the inhibitory effects of novel phosphodiesterase 4 inhibitor ZL-n-91 to the proliferation of leukemia cells L1210 and K562.
				        	
METHODS:CCK-8 method was used to detect the effect of ZL-n-91 to the proliferation of L1210 and K562 cells, and the proliferation rate, IC
RESULTS:ZL-n-91 showed a significant inhibitory effect to the proliferation of leukemia cells L1210 and K562 in a dose-dependent manner (P<0.001). After treated by ZL-n-91, the leukemia cells L1210 and K562 in the S-phase in cell cycle decreased significantly compared with those in control group (P<0.01). The apoptosis of leukemia cells L1210 and K562 could be induced by ZL-n-91 (P<0.001), and the expression level of apoptosis related protein BAX significantly increased. In the animal experiment, the result showed that ZL-n-91 could significantly inhibit the growth of subcutaneously transplantation tumor (P<0.05).
CONCLUSION:The novel phosphodiesterase 4 inhibitor ZL-n-91 can effectively inhibit the proliferation of leukemia cells L1210 and K562, which has the potential of anti-leukemia drug development.
