异硫氰酸酯的抗癌活性与结构的关系
On R-NCS cancer chemopreventative properties
【摘要】 给出了异硫氰酸β-苯基乙基酯(PEITC)、异硫氰酸苄基酯(BITC)、异硫氰酸1-萘基酯(NITC)及异硫氰酸丙烯基酯(AITC)的结构信息含量指数(SIC)与抗癌活性(IC50)的关系即:IC50=20.41-24.90SIC,其相关性R=-0.9425,计算了其他异硫氰酸酯的IC50值。对于R—(CH2)n—NCS而言,其中R=Me,Ph或其他基团,IC50值随着n值的增加而增大。
【Abstract】 The relation between the structure information content(SIC) index and cancer chemopreventative properties(IC50) of organic isothiocyanates (ITCs) such as 1-naphthyl isothiocyanate (NITC), benzyl isothiocyanate (BITC),β-phenylethyl isothiocyanate (PEITC) and allyl isothiocyanate(AITC)is given.It is IC50=20.41-24.90 SIC,its correlation coefficient R=-0.9425, and others ITCs(R-(CH2)n-NCS) IC50 values are calculated by the relationship. The calculating results show that IC50 will be bigger with increasing.
