For example: antimalarials primaquine morpholine, flutter malaria quinoline, quinine, chloroquine, quinacrine; antibacterial drugs have sulfa drugs, chloramphenicol and furans; antipyretic analgesics are acetyl salicylic acid, phenacetin, acetanilide, antipyrine, aminopyrine; other drugs such as vitamin K, probenecid, hydralazine, quinidine, methylene blue, toluene and so on.

抗疟药伯氨喹啉、扑疟喹啉、奎宁、氯奎、阿的平；抗菌药有磺胺类药物、氯霉素及呋喃类；解热镇痛药有乙酰水杨酸、非那西丁、乙酰苯胺、安替比林、氨基比林；其它药物如维生素K、丙磺舒、肼苯哒嗪、奎尼丁、美蓝、甲苯等。

Despite of some difference effected by acetosalicylic acid between this two kind of plants,we found that the enhancement of relative membrane penetration by heavy metal stress was reduced, the peroxidation of membrane lipids was alleviated and to some degree protected the membrane from injury by Cd~(2+),thus ultimately promoted the tolerance ability of plants to heavy metal stress .

尽管乙酰水杨酸对两种实验材料发挥作用的浓度范围有一定差别，但在受镉离子污染的培养液中施加乙酰水杨酸后，乙酰水杨酸均能有效的抑制重金属Cd~(2+)胁迫引起的细胞膜透性增加、膜脂过氧化水平升高，从而延缓了重金属对膜结构的损伤，最终增强了植物体对水体重金属污染的抵抗能力。

Therefore, the author excogitates some synthesis courses of new compounds including selenium and aspirin based on medicament chemistry and coalition principle. The new compound is named 5-5'-diselenium monoacetyl salicylic acid and ascertained by IR ,UV and MALDI-TOF-MS, and its structure is: OOHThe compound is inhibiting to sarcoma and ascites tumour of white mice by pharmacology experiments, so it is worth researching deeply.

为此，本文运用化学拼合原理，提出了几种既含硒又含乙酰水杨酸的化合物新结构的合成路线，经过多次理论分析和探索试验，得到一种预测的新的化合物，命名为5-5′-二硒单乙酰水杨酸，经红外、紫外、飞行时间质谱测定，证明该化合物的结构为：经药理预试验表明，该化合物对小鼠S_(180)肉瘤和艾氏腹水型肿瘤均有抑制作用，具有深入研究的意义。
