Chapter 219 Sulfonamides

"It's amazing. The taste changes layer by layer."

Ethan put down the empty water cup and felt the changes on his taste buds.

The last layer of purple tastes cold and bitter, but it is fragrant and sweet after drinking. It feels endless aftertaste.

The old man smiled slightly: "White feather flowers can increase the ability to taste, but it's a pity that the number is too rare."

For a pharmacist, taste is a very important attribute. Through taste, the main ingredients of the medicine can be distinguished and whether the preparation is balanced.

This is a heavy gift.

"Yesterday I received a letter from an old friend. She told me about Professor Taylor's death in the letter. I think you should have guessed it."

Ethan was stunned, and then reacted: "It should be Master Fanta. I had the honor to visit the master himself in Milan on my way back."

Vic nodded and tasted the water in his hand carefully: "Alas, things are unpredictable. Professor Taylor is my good friend. I didn't expect him... Alas."

He shook his head, his face sad, obviously very sad.

"Professor Taylor is a treasure in the entire Federation's mystical world. His talent in linguistics is unmatched. His death is a loss to the entire Federation."

Ethan remained silent. Although he knew that Professor Taylor was a top scholar in the Federation, the two had never met, and he just felt a little regretful.

"So I want to hold a memorial service at Flo University to commemorate Taylor's departure. Since you know Master Fenda, I think it is necessary to inform you."

"Professor Taylor is a professor worthy of respect. I feel very honored to be able to attend this memorial service."

Ethan nodded slightly and accepted Principal Vic's invitation.

The principal didn't seem to know that he was the first to know the news of Taylor's death. It seemed that Professor Fenda didn't tell him more information.

"I will let my messenger pass on the specific time arrangement to you."

Principal Vic raised his right hand, and a snow-white parrot appeared on his arm.

"This is my messenger-Moses."

"Moses Moses~"

The white parrot flapped its wings and called its name.

It is rare to see a parrot as a messenger. In his impression, most parrots belong to the Parrot Newspaper.

Ethan took out some nuts from the badge and fed it. Obviously, this trick gave him a lot of impression points.

"Moses Moses~"

After eating the nuts, Moses flew away.

"Haha, Moses is a bit greedy, but he is quite capable."

"There is another thing today, which is about the Rainforest Trial. First of all, congratulations on winning the Rainforest Trial."

Vic said here with a smile on his face, and he was obviously very happy about this matter.

Turing has not won the Rainforest Trial for many years. Last year's fourth place was the best result in recent decades.

Unexpectedly, Ethan, a guy who forced the duck to the shelf, actually gave everyone a surprise.

Indeed, the reason why Ethan was able to participate in the Rainforest Trial was because he saved the noble merchant group from Zion City at a critical moment. The Pharmacist Association immediately recommended him to be a contestant this time.

Now I think the choice at that time was indeed a bit risky.

But fortunately the result was good.

"So I have another invitation."

Principal Vic paused deliberately, then smiled at Ethan.

"Invite you to the Alumni Wall of Flo University."

The Alumni Wall is a collection of students who have made outstanding contributions.

This is a symbol of honor.

Hanging your own portrait on the Alumni Wall is the highest pursuit of every student of Flo University.

"Ah, I am honored to accept this invitation."

Ethan certainly did not refuse this.

"In addition, as a reward, you will get a chance to enter the school's secret library."

Ethan was shocked.

The Secret Library of Flo University is a very mysterious place. Legend has it that there are many very precious books in it, including special knowledge such as history, language, secret arts, and formulas.

"Thank you so much, Mr. Principal, this is a surprise."

Ethan smiled happily. He had heard of the secret library in the school for a long time, and finally had the opportunity to see it.

In addition to the school's rewards, the city government's rewards should be more abundant, but I don't know why no one has contacted me yet.

After leaving the principal's office, it was almost noon, and Ethan went directly to the Lone Tower Laboratory.

The research and development of anti-snake venom serum has basically come to an end, and snake venom antibodies for almost all kinds of toxins have been cultivated.

Manufacturing and sales have long been on track, but due to the current production capacity, the price of anti-snake venom serum has risen again and again, and now each bottle of medicine is sky-high.

Ethan wanted to increase production capacity, but there was no way. This world could not achieve large-scale automated production, and was affected by snakes and horses, so he had no choice but to maintain the status quo.

At the same time, through this period of experience, Ethan discovered the shortcomings of this world.

As a high-level martial arts world, casualties in conflicts are very common, but everyone seems to rely too much on the baptism of the Church of Light.

There is no way that if the external injuries cannot be repaired in time, it is very easy to get infected without antibiotics.

Once the infection and suppuration occur, there is almost nothing you can do.

Even the baptism of light cannot cure it.

Especially in the process of land reclamation, if you rely solely on the priest's baptism of light, it will not only delay time, but also waste a lot of money.

So Ethan wants to develop a class of antibiotics.

There are many types of antibiotics, and the first one is penicillin.

Penicillin can kill bacteria quickly, and it was a very commonly used drug even in the previous life.

However, the cultivation of penicillin is extremely strict, at least it requires a sterile environment, but the cultivation cycle is long, and the screening is also extremely complicated. At this stage, there is no corresponding environment and instrument conditions, and it is impossible to produce it.

So compared to penicillin, Ethan prefers another drug sulfonamide.

Sulfonamide is also a kind of antibiotic, and it is a broad-spectrum antibiotic that has a strong inhibitory effect on many kinds of bacteria.

But unlike penicillin's rapid sterilization, it mainly inhibits the growth of bacteria and is a long-term antibacterial agent. Although it is not as fast as penicillin, it is more lasting and safe.

The most important thing is that this substance is mainly artificially synthesized, does not require a long and strict cultivation and screening process, and is also very simple to use, and can be directly applied externally.

In the previous life, sulfonamides were first discovered from dyes. The synthesis process was not complicated and the cost was low. Once it came out, it was widely popular.

Judging from the current situation, Ethan is confident that he can synthesize it.

Sulfonamide drugs are mainly synthesized by acetanilide, chlorosulfonic acid, liquid ammonia, liquid alkali, etc. in proportion. Relatively speaking, these substances can still be obtained after repeated experiments.

Thinking of this, Ethan built a corresponding preparation template in his mind.

Of course, it is not a simple matter to extract raw materials from the substances that exist in the current world, so he repeatedly revised it many times in a day, and finally determined a version in the evening.

PS: Thanks to the book friends who actually really look down on the genuine version and the book friends Nimotomachi G forget-me-not for their rewards. The cold winter night is no longer cold, awesome.

PS: Recommendation ticket, monthly ticket fast lane.

PS: Book group: 189698162, come to the bowl quickly~

I wish all book friends a happy New Year's Day, a new year and a new atmosphere.
