| 摘 要： | 本文利用蚕豆细胞微核试验评价了１０种氮杂环类化合物的遗传毒性，一化合物的最低未占据轨道能Ｅｌｕｍｏ、分子的量负的原子净电荷ｑ建立了较好的相关方程：ＭＮ＝－２．９６（１．１４）＋４．９３（０．４８）Ｅｌｕｍｏ＋１３．６８（２．７２）ｑ＾－Ｒ＾２＝０．９４ ＳＥ＝０．７１ Ｆ＝５３．９２ Ｐ〈０．０００５推测此类化合物的至于致毒机制可能是它们作为电荷给予体和氢键予体作用于生物受体而引起的突变。

| Abstract: | The genotoxicity of 10 heterocyclic nitrogen compounds were evaluated using mi-cronuclei test,and were correlated with Elumo(the lowest unoccupied molecular orbital energy) and q- (the most negative net charge in molecular):MN=-2.96(1.14) + 4. 93(0. 48)Elumo + 13. 68(2. 72)q-R2 = 0. 94 SE = 0. 71 F=53. 92 P<0. 0005 |
