In the past hundred years, the average life span of human beings has been greatly extended. In addition to the improvement of living conditions, another main reason is the continuous improvement of medical standards. The continuous advent of various therapeutic drugs is a prerequisite for the improvement of medical standards.

Medicine is a special product that is closely related to human life and is the patron saint of life. Its development process has been full of ups and downs, and its magical preparation process and production technology are the crystallization of human wisdom.

In distant ancient times, people knew that willow bark had certain antipyretic and analgesic effects, but they did not know what the active ingredients were. It was not until 1800 that someone extracted from willow bark an antipyretic and analgesic effect.

An active ingredient called salicylic acid.

In the following decades, in order to overcome the side effects of the drug in clinical applications and expand its therapeutic scope, technical experts in the industry made many improvements to the extraction and synthesis processes of aspirin. The active ingredient was changed from salicylic acid to acetyl acetyl.

Salicylic acid, the dosage form has been developed into enteric-coated sustained-release tablets.

Since its clinical application, this drug has saved tens of millions of lives, eliminated or alleviated the pain of countless people, and created the immortal legend of a century-old drug, aspirin.

Before penicillin officially became a clinical drug, humans were at a loss to treat bacterial infections. Tuberculosis alone had claimed tens of millions of lives in history. At that time, when tuberculosis was mentioned, people turned pale when talking about it.

In fact, the scientist Alexander Fleming accidentally discovered penicillin in an experiment in 1928. However, the biological culture technology was backward at that time. The key was the lack of efficient and practical separation and purification processes, which made it impossible to obtain high-quality products with practical value, resulting in

For a long time, human society failed to realize the importance of penicillin.

Ten years later, through unremitting efforts, many scientists finally found methods to separate and purify penicillin. However, these process technologies were limited to laboratory applications and were far from the requirements for large-scale production.

It was not until 1941 that scientists not only discovered a method to efficiently cultivate penicillin, but also successfully used corn syrup as the culture medium, laying the foundation for the industrial production of penicillin.

Scientists from Oxford University invented the freeze-drying method to separate and purify penicillin in 1942. They used this technology to obtain high-quality penicillin crystals. This was a landmark technological breakthrough that removed the biggest obstacle to the clinical application of penicillin.

Utilizing existing process technology and with the full cooperation of scientists and entrepreneurs, large-scale production of penicillin was finally achieved in 1943.

Since its extensive use in clinical treatment, penicillin has not only saved hundreds of millions of lives in its seventy or eighty-year history, including war years and peacetime, but also provided a broad perspective and ideas for the subsequent development of new antibiotic drugs.

The famous artemisinin has made mainland China the first winner of the Nobel Prize in Science (Physiology and Medicine). Professor Tu Youyou’s success lies in her discovery of ether extraction to separate and extract artemisinin from Artemisia annua.

Craftsmanship.

Artemisia annua is a plant that is widely distributed naturally. Its efficacy has long been recorded in ancient Chinese medicine prescriptions, but modern medicine has higher requirements for its use.

Although everyone knows that the active ingredient of Artemisia annua is artemisinin, many attempts have been made to extract the active ingredient and make it convenient for clinical use. However, either the active ingredient is destroyed or high-purity crystals cannot be obtained.

.Professor Tu took a new approach, starting with solvent extraction, and found that ether extraction was the most effective. The innovation of the extraction process solved a problem that had troubled scientists for many years...

Eating Gangu and giving birth to a hundred diseases is the objective reality facing human beings. Generally, small problems such as cold and fever can be healed by the human body's own immune system. Human beings will be in a state of rashness with significant effects.

Faced with the new crown virus that is raging worldwide and is said to coexist with humans, it must eventually rely on effective treatment of drugs, so that social life can return to the right track. Some diseases, even if the drugs cannot be completely cured, can help humans to relieve the condition.

There are neither medicines for longevity, nor does it contain all kinds of diseases. Although the drug itself also has the defect of "three -point drug poison", in addition to air, water, water, food, food, food, daily, and other necessities. What is missing, this is a fact that no one can deny.

It is expected that the effect of higher curative effect, smaller toxic side effects, and even no poisonous side effects are the common wishes of human beings.

Fang Hanmin is a high school student at 985 university. He not only obtained a doctor of pharmacy and pharmaceutical sciences in Oxford University. After graduation, he also became the project director of the European RGP Company's New Medicine Creation Center. By the end of the 1970s, it was attached to a temporary worker with the same name and the same name in the Red Star Pharmaceutical Factory.

As an overseas red, although in Europe, Fang Hanmin will return to China sooner or later, but he did not expect to come back in this way.
