A novel series of nonsteroidal heterocycles was discovered which display cell-type selective, high-affinity (nanomolar) binding to the progesterone receptors from TE85 osteosarcoma cells but > 1 microM binding affinity to the progesterone receptors from T47D and ZR75 human breast carcinoma cells. Structure-activity relationships were developed for a set of these compounds, and a representative analog
发现了一系列新的非甾体杂环化合物,它们显示与TE85骨肉瘤细胞的孕激素受体的细胞类型选择性,高亲和力(纳摩尔)结合,但与T47D和ZR75人乳腺癌细胞的孕激素受体的结合亲和力> 1 microM。建立了一组化合物的结构活性关系,并选择了具有代表性的类似物1-(3,4-二氯苯甲酰基)-3-苯基-1,4,5,6-四氢哒嗪++ +(1i,RWJ 25333)进一步评估。RWJ 25333刺激人成骨细胞样细胞的体外增殖,但不刺激人乳腺细胞的体外增殖。
