SAR在药物化学里的名词解释

急!求解一道药物化学的翻译
Nitrovinylstilbenes 7ak were evaluated for their antiproliferative activity against a panel of four different human tumor cells from cervix, breast, lung, and neuroblastoma using the sulforhodamine B assay and were compared with the reference compound resveratrol (1). As shown in Table 1, all of the synthesized compounds possessed antiproliferative activities against these cell lines in a concentration-dependent manner and were more active than resveratrol. The 4-fluoro (7a), 4-methyl (7c), 4-methoxy (7e), and 3,4-methylenedioxy (7g) derivatives exhibited IC50 values of

跪求药物化学《苯佐卡因的合成》实验的思考题答案
合成苯佐卡因的操作步骤：
（1）酯化 用对硝基苯甲酸和乙醇在浓硫酸里反应,反应完毕趁热将液体倒入冷水中,搅拌,冷却,抽滤,抽滤后所得固体产物要加15%碳酸钠溶液洗涤.最后再抽滤才得到对硝基苯甲酸乙酯.请问加15%碳酸钠溶液洗涤的作用是什么?写出反应的化学方程式.
（2）还原 上一步得到的对硝基苯甲酸乙酯,加铁粉、水、冰醋酸和乙醇反应,反应完后慢慢加10%碳酸钠溶液,搅拌过滤,滤液加水就可析出所要的最终产物苯佐卡因,请问加10%碳酸钠溶液的作用是什么?写出反应的化学方程式.
（3）如果产品中夹有铁盐（产品颜色发黄）,应如何除去?
