positron emission tomography or single photon emission computed tomography. We synthesized fluoro and iodo analogues of tamoxifen, and these halogenated analogues produced greater affinity for binding to the receptor than tamoxifen. Values of the inhibition affinity constants were as follows: tamoxifen, 15,000 nM; fluoromethyl-N,N-diethyltamoxifen, 2500 nM for the cis isomer and 500 nM for the trans isomer;
进行这项研究以开发用于通过正电子发射断层扫描或单光子发射计算机断层扫描对雌激素受体阳性乳腺肿瘤成像的配体。我们合成了他莫昔芬的氟代和碘代类似物,并且这些卤代类似物比他莫昔芬产生更大的结合受体亲和力。抑制亲和常数的值如下:他莫昔芬,15,000 nM; 氟甲基-N,N-二乙基他莫昔芬,顺式异构体为2500 nM,反式异构体为500 nM;和碘甲基-N,N-二乙基他莫昔芬,顺式异构体为1500 nM,反式异构体为1000 nM。在对人MCF7乳腺肿瘤细胞生长的研究中,在50%的病例中抑制肿瘤生长的浓度如下:他莫昔芬为11 microM;而他莫昔芬为11 microM。氟甲基-N,N-二乙基他莫昔芬,顺式和反式异构体分别为4.5和11.8 microM,分别; 和碘甲基-N,N-二乙基他莫昔芬分别为2.4和6.3 microM,分别为顺式和反式异构体。这些研究表明,他莫昔芬的氟代和碘代类似物可能
