A series of chalcone analogues and some of their derivatives were synthesized and subjected to the mosquito larvicidal study. Chalcones having electron releasing group(s) on either ring A or ring B showed high toxicity. Electron withdrawing group(s), especially at ring B, reduced the activity of chalcones. The activity was abruptly decreased due to replacement of ring A by CH3, extension of conjugation

certain groups of compounds was similar. For some groups of compounds, cytotoxicity was correlated with the sigma, pi, or molar refractivity constants in the aryl ring attached to the olefinic group. In addition, the IC50 values in all three screens correlated with the redox potentials of a number of Mannichbases. X-ray crystallography and molecular modeling of representative compounds revealed various

A series of novel 4-thioquinazoline derivatives containing chalcone moiety were designed, synthesized and systematically evaluated for their antiviral activity against TMV. The bioassay results showed that most of these compounds exhibited moderate to good anti-TMV activity. In particular, compounds M2 and M6 possessed appreciable protection activities against TMV in vivo, with 50% effective concentration

Abstract A series of novel chalcone derivatives containing purine moiety was designed and synthesized, and their antiviral activities against cucumber mosaic virus (CMV) and tobacco mosaic virus (TMV) were evaluated in vivo. Bioactivity assays indicated that some compounds showed good antiviral activities against CMV and TMV. It is worth mentioning that compounds 3o, 3s, 3w, and 3x exhibited excellent
