  The synthesis and photoactivated cytotoxicity of novel 5-phenyl-3-(2,2′:5′,2″-terthien-5-yl)-4,5-dihydro-1H-pyrazolines

  摘要：

  A series of novel 5-pheny1-3-(2,2':5',2 ''-terthien-5-yl)-4,5-dihydro-1H-pyrazolines were synthesized in this report. Their photoactivated cytotoxicities on the Spodoptera 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 5, 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. (C) 2013 Zhuo-Hong Yang. Published by Elsevier B.V. on behalf of Chinese Chemical Society.

  A new class of chiral C2-symmetrical diamino-oligothiophenes is described to be effective in catalyzing Pd-mediated asymmetric allylic alkylations in a highly enantioselective manner. The combination of experimental as well as crystallographic evidence revealed the key role played by sulfur-based heteroaromatic rings in the stereodiscriminating step of the procedure. In particular, unprecedented non-covalent
