nucleoside analogs

Nucleoside analogs are modified versions of natural nucleosides, which are the building blocks of DNA and RNA. These analogs can mimic the structure of nucleosides but have slight differences that can disrupt the normal processes of genetic material replication and function. Due to their ability to interfere with viral or cancer cell replication, nucleoside analogs are often used as antiviral or anticancer medications. By targeting and inhibiting the growth of pathogens or tumor cells, they help in treating various diseases while minimizing the effects on healthy cells.
