Kind: captions Language: en So given how advanced we are with our capabilities, it it I wonder why there's a certain capability that we don't have. And here's what that is. We're constantly, you know, I constantly hear about researchers going to the Amazon, finding some plant or animal that creates some novel molecule that's useful for us. But why can't we say, "Oh, here's a problem we have. I'm going to use my computational powers to calculate what molecule I need to deal with that problem. Then I'm going to synthesize that. So instead of searching for it in nature, >> take on that role ourselves, but in a in a direct way. >> We do both. We really do both. And I'll just I'll give an example. So for example, >> you know, we have so much better control of AIDS now than we did in the beginning or even the middle of the AIDS crisis. And a lot of those drugs are designed by humans out of thin air. Okay? We're saying, "Okay, I need to design a drug that's going to fit into a pocket of an enzyme and shut that thing down and we design that on computers and we make it in the lab and then we test it and there you go." Okay, so that's drug design sort of from scratch. We do it. >> Okay. At the same time, nature has had millions and millions and millions of years to work on some of these things and come up with sometimes pretty complicated chemistry, a lot of antibiotics, etc. Those aren't things that a chemist would synthesize just in their spare time someday, right? They've got they're fancy looking molecules when you first look at them >> and you're like, "Yeah, nature's has come up with." Sometimes those are they're made by you know sort of longer pathways lots of chemical modifications because like those arms races that have been happening between you know say a fungus and bacterium in the soil oh my gosh those are so old those so let's exploit what nature's been tinkering with for millions and millions of years >> millions of millions you mean tens of millions of millions hundreds of millions of years etc yeah >> I mean a great example that underappreciated story is the first statin >> what is a statin >> statin everybody People aren't no stat people are on statu clan is from >> people on statins to control their cholesterol. >> Oh right. Yeah. >> Okay. The first statin >> came from a fungus because a a Japanese researcher I'm going to say back in the early 80s thought you know if I can stop the cholesterol metabolism uh I'm going to if I can get involved with cholesterol metabolism I could really benefit for example um cholesterol levels in humans. Well, I'm betting that somewhere out there in nature that's a strategy that some fungus used to stop, you know, an invader. And he screened like 6,000 strains. >> Wait a minute. How did he make that connection? Human cholesterol is a fungus stopping bacteria. That's [laughter] >> Yeah. Well, it was kind of the same strategy people use to find antibiotics, right? Is is a lot of these things are are fungal products are antibiotics. So, he thought there must be like an antibiotic I can use for cholesterol, >> right? >> Because cholesterol is used in making membranes. He thought, "Okay, that that might be a target that that fungus would use." >> I think he screened like 6,000 strains. >> Wow. >> fungi. >> And that launched a drug revolution. Came up with the f the first statin. And once you got the first statin, you got the first principle. And then the chemist came along and they said, "Okay, we'll modify this. We'll modify that. We'll make this a little more potent. We'll make this a little, you know, easier on the stomach, whatever." But the first statin was pulled out of nature. So there's two strategies going. Use nature if you can. And I I feel the same way even with antivenenoms. >> These animals have had >> tens of millions of years to work on these defense mechanisms. Let's exploit that knowledge while at the same time we in the laboratory we can also use our you know we got ever more powerful tools for designing drugs. But >> um >> so you want to do both. >> We live at a time we live in a time where we can do both. We do do both and let there and and let the competition you know begin. We because very often in in drug development there's a first generation where you didn't have something then you have something >> but you know it's like this was true for AIDS I mean you had to take so many different pills and they were so big and there were side effects and all that stuff. So over the years, what you work on are more potent drugs operating off those first principles, less toxic, right? More convenient to take, uh, you know, and and it's the same thing going on with late weight loss drugs right now. You know, you know the root of this weight loss. Yeah. You know the root of this? >> No, >> the root of this. >> Tell me monsters. >> What? No way. >> Yeah. This is a discovery. The weight loss drugs are based on a discovery made in Hila Monsters. So reptiles, you know, can go a long time between meals. >> Yeah. Yeah. >> How do they do that? How do they control their body physiology in these long periods? >> They're coldblooded. >> No, they they're doing a little more than that. >> So the lead to what became Ompic and Mjaro and all that kind of stuff were discoveries in Hila monsters. >> Wow. This is why when you talk to biologists, we plead for the support of basic research. >> Yeah. >> Because we we we the more we learn about how nature works, we come up with new ideas of how to, for example, intervene in in human medicine. And if it weren't for people studying how Hila Monsters regulate their physiology in the long gaps between meals, >> we wouldn't have these weight loss drugs, which we now start to understand are helping cardiovascular health, liver health, all this kind of stuff. And we're going from injectables, right? Because you're watching the watching the evolution of the drug making to now oral, which is a lot more convenient, a lot easier for compliance. We're also reducing side effects, etc. It's the same story being told. A lead from nature. >> Yeah. a first-in-class drug. Then you know the create the collective human creativity gets involved and we come up with things that are more potent, safer to take etc.
