Applications of macrocyclic molecules in cancer therapy: Target cancer development or overcome drug resistance

Researchers have identified macrocyclic compounds as a potential solution for targeting proteins critical to tumorigenesis, blocking nearly 80% of cancer's signature characteristic events. Additionally, these small compact molecules can effectively overcome drug resistance by binding to mutant proteins and inhibiting their activities.
