Let’s start with the basics!

We’re all chemical engines—but what exactly is a chemical? Simply put, chemicals are forms of matter—anything that takes up space and exists as a solid, liquid, or gas. In living organisms, biochemicals form complex networks that keep us alive and balanced—a state called homeostasis. Drugs are chemicals too, and they work by interacting with these networks to change how the body functions. Understanding these basics helps scientists design better treatments—and helps patients make more informed decisions about their care.

The host of the show is Dr. Stanley Crooke, a scientist, a physician, an entrepreneur and the father of antisense technology. Dr. Crooke is responsible for driving the development of antisense or ASO technology, an RNA-targeted technology responsible for the commercialization of three best- and first-in class medicines and more than 40 drugs in development. In 2020, Stan formed n-Lorem to use this powerful technology to develop experimental personalized ASO medicines for nano-rare patients (1 to 30 patients worldwide) for free, for life.
