What is the significance of an amino group in medicine?

In medicine, amino groups are very crucial due to their presence in many drugs. For instance, penicillin consists of a four-membered beta-lactam ring linked to a five-membered thiazolidine ring with an amino group. Metformin is a treatment for people with type 2 diabetes and also contains an amino group. In gene therapy, amino groups are also very important. They are found in polymeric nanoparticles that help deliver genetic material, as the amino groups facilitate DNA condensation and improve gene transfer efficiency. Additionally, amino groups are basic and can form hydrogen bonds, which can increase a drug’s solubility in water, and its ability to interact with biological targets. The stability and reactivity of the amino group can influence the duration of the drug’s action.
