摘　　要：A series of novel 5-phenyl-3-（2,2＇：5＇,2″-terthien-5-yl）-4,5-dihydro-lH-pyrazolines were synthesized in this report. Their photoactivated cytotoxicities on the 5podoptera litura （SL） cell line were evaluated using the MTT method. It was noticed that the inhibitory activities of all the conjugates was enhanced when irradiated with UV-A light. Compounds 4, 6 and 8 were found to be most effective with inhibition rates of 88.1%, 88.0%, and 90,5%, respectively, For compound B, the inhibition rate value was only slightly enhanced under the irradiation treatment （78.3%） compared to the dark treatment （74.8%）. The relationship analysis between structure and activity showed that the middle thiophene ring played an important role on the inhibitory activities. It was shown that these compounds could be the potential candidates for new photoactivated pesticides.A series of novel 5-phenyl-3-（2,2＇：5＇,2″-terthien-5-yl）-4,5-dihydro-lH-pyrazolines were synthesized in this report.
