Adenosine derivatives are chemical compounds that are structurally related to adenosine, a nucleoside composed of adenine and ribose. These derivatives often play crucial roles in biological processes, including energy transfer and signaling within cells. Common examples include ATP (adenosine triphosphate), which serves as the primary energy currency in living organisms, and cAMP (cyclic adenosine monophosphate), a key signaling molecule. In addition to their biological significance, adenosine derivatives are also studied for their therapeutic potential. Some derivatives are used in medications to treat conditions like arrhythmias and asthma. Researchers continue to explore their roles in various physiological processes and their potential applications in medicine.
