Chapter 753 Head-up (2)

"Before today's lecture, I have a question."

Shen Guanglin stood on the stage, facing thousands of audiences, he was not stage fright at all, but talked with eloquence.

Shen Guanglin pointed to an uncle with a Mediterranean hairstyle and said, "Excuse me, sir, where are you from? Judging by your appearance, you must not be Swedish."

"You're right, I'm a cowboy from Spain." The middle-aged man who was named was very excited. His hair style was very Mediterranean, and he looked like someone nearby.

"Then what is your purpose for coming to Sweden?" Shen Guanglin continued to ask.

"Just to listen to your lecture." Although the middle-aged man is Spanish, he speaks good English and is fluent. Publish new discoveries."

"Who said I would publish new discoveries?" Shen Guanglin was very curious. Has this really spread?

"With the strength of Professor Shen, I believe that you have made many new discoveries, but it is also our honor if we can witness your new discoveries."

The Mediterranean is still very good at talking, which made Shen Guanglin very happy: "Let's start the lecture, I will definitely not let you down."

After finishing speaking, Shen Guanglin smiled confidently, and then began his lecture.

Sure enough, everyone listened very carefully. Professor Shen is really going to start talking about his new discoveries.

"Everyone knows that catalysts are very important in chemical reactions. We conduct various experiments. In order to increase the reaction speed and experimental effect, we usually add some catalysts. For a long time, there are only two kinds of catalysts, metals and enzymes.

Today, I will talk about something different. "

Shen Guanglin released a slide, which is a chemical molecular formula. Many chemists or biologists present here know that it is an organic molecule.

"It's not an ordinary molecular formula, it's one of the third class of catalysts I've discovered, it's based on small organic molecules that make the sides of chiral molecules asymmetric, so I call it asymmetric organic catalyst."

Sure enough, Shen Guanglin talked about his new discovery, which was the discovery of a third organic catalysis other than enzymes and metals.

Chemistry is niche, and many people don't care what organocatalysis is.

However, in 2021, the Nobel Prize in Chemistry was awarded to the English chemist David Macmillan and the German chemist Benjamin List.

The Nobel Prize in Chemistry was awarded for their discovery of asymmetric organic catalysts.

And they discovered this catalyst in 2000, and Shen Guanglin gave this lecture in 1988, so there is really no need to think about crashing.

For the time traveler, even if they want to copy official documents, they must be copied reasonably. Some time travelers release popular songs one month in advance, which is only done by a sick mind.

The organic catalyst that Shen Guanglin is releasing now is actually a subject that their laboratory has been researching for a long time.

You should know that when Shen Guanglin's laboratory first came into contact with chemistry, he studied chiral molecules.

As I said at the time, chiral molecules refer to molecules that are exactly the same in composition but whose spatial structures are mirror images of each other, just like the left and right hands of a person. They are mirror images of each other, but they cannot overlap.

Speaking of which, Shen Guanglin's laboratory has been studying chiral molecules for several years, and asymmetric organic catalysis is one of the research results of their laboratory.

Hmph, inadvertently, this is another Nobel Prize-level achievement.

Moreover, the applicability of the achievement of asymmetric organic catalysis is also very good, and it has great promotion value.

However, the domestic pharmaceutical and chemical fields are underdeveloped, so Shen Guanglin held back this achievement for a long time.

Now, he wants to cash in.

If you don’t sell it this year, it won’t be easy to sell it next year.

Then, about chiral molecules and asymmetric organic catalysis, Shen Guanglin suddenly started to talk about it in great detail.

"Molecular properties that are mutually chiral can vary widely, and often we only need one of them. Especially when making pharmaceuticals, the other is likely to be detrimental, which is important."

While speaking, Shen Guanglin played a video about the side effects of the other half of the chiral molecule.

This is a true story that happened in the 20s, when a lack of understanding of chiral molecules led to a nasty "reactive stop event".

What Shen Guanglin was looking for was the documentary of that time.

At that time, some doctors in Europe and the United States often gave pregnant women a kind of "reactin" drug as an analgesic or cough medicine.

However, many pregnant women gave birth to babies with congenital deformities after taking "Thalassaline".

Later, after research, it was found that in the "reactin" drug, the right chiral molecule has the effect of inhibiting pregnancy reactivity, while the left chiral molecule has a strong teratogenic effect on the embryo.

When the TV screen ended, everyone was shocked.

"As we all know, in the absence of human intervention, the proportion of two chiral molecules in chemically synthesized drugs is almost equal.

Therefore, as long as there is a certain catalyst, in the process of producing drugs, it is judged whether another chiral molecule is harmful to the human body in addition to the chiral molecules required by the drug. If it is harmful, asymmetric organocatalysis can be used to selectively synthetic molecules. "

Shen Guanglin talked about the past, present and future of asymmetric organic catalysis in one breath, and he has a very clear judgment on the whole industry.

Before the words were finished, the eyes of Astra's people turned red, and they almost stopped Shen Guanglin from continuing.

Such a good patent, such a major discovery, if Astra owns it, how much development convenience and competitive advantage will it have?

However, this is a public lecture, and no one can stop Professor Shen from spreading knowledge.

Shen Guanglin's lecture was finally over, and he asked back, "Is the chemical discovery I talked about today awesome?"

Awesome!
For the vast majority of scholars, they usually do not expect to win a Nobel Prize for scientific research.

After all, there is only one award a year in the world, and there are only five awards in total. After all, the Nobel Peace Prize does not count.

Of course, the Nobel Prize in Literature is not so authoritative. For example, Haruki Murakami is popular every year, but he cannot win it every year.

For most scientific researchers, their goal is not to win the Nobel Prize, but to achieve a commendable achievement, which is already very good.

Today, just one exhibition, Shen Guanglin has announced two such achievements.

It's amazing!
Moreover, based on everyone's simple judgment, it seems that these two achievements are very extraordinary.

No one knows whether ultrasonic cleaning can win the award, but the prospect of studying chiral organic catalysis sounds too broad.

In the future, in the field of chemistry and pharmaceuticals, this will open a new door.

For most scientific researchers, the Nobel Prize is a tall tower. The closer to him, the more he needs to look up.

As for Shen Guanglin, he didn't approach in a hurry, but built steps beside the tower. Now, the tower he built has a tendency to surpass the tower.

This is the same as siege in ancient times, when attacking from below, it is difficult for arrows to approach.

But after the two places are on the same plane, they can confront each other or even look down on them.

Shen Guanglin is standing on a high place now, he can already look at Nobel.
