在和疾病的斗爭中,現有的药物还远不能滿足人民的需要。不但还有很多疾病沒有特效的药物,如病毒性疾病和癌疾等,就是現有的特效药也还有很多缺点。所以改良現有药物与寻找优良新药的研究仍是目前化学工作者的重要任务之一,在世界文献中也占着很大的比重。历年来的工作积累了不少宝贵的經驗,可是由于人們对于治病机制还缺乏足够的认識,因而迄今未能概括出全面性的理論体系,只有若干零散而又不很成熟的規律。这对于从事于药物研究的化学工
In the fight against the disease, the existing medicines are far from meeting people’s needs. Not only are there many drugs that have no special effects on diseases, such as viral diseases and cancer diseases, but there are still many shortcomings in the existing special medicines. Therefore, improving the existing drugs and looking for good new drug research remains one of the important tasks of the current chemical workers in the world literature also accounts for a large proportion. Many valuable experiences have been accumulated in the past years. However, due to the lack of sufficient understanding of the mechanism of treatment, no comprehensive theoretical system has so far been drawn up, with only a few fragmented but not very mature laws. This is for chemical workers engaged in drug research
