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
合成了一系列查尔酮类似物及其一些衍生物,并进行了蚊幼虫研究。在环A或环B上均具有电子释放基团的查耳酮显示出高毒性。吸电子基团,特别是在B环上,降低了查耳酮的活性。由于通过CH 3取代环A ,扩展结合或衍生化查耳酮的α,β-不饱和酮部分,其活性突然降低。这些化合物的定量结构-活性关系(QSAR)研究使用各种空间,电子和物理化学参数进行。使用线性和样条选项的遗传函数近似作为开发QSAR模型的化学计量工具。
