Pyrimidine Analogs

Pyrimidine analogs are a subclass of antimetabolite drugs structurally designed to mimic endogenous pyrimidines such as uracil, thymine, and cytosine By inhibiting essential nucleic acid synthetic enzymes—such as thymidylate synthase or DNA polymerase—or by directly incorporating into DNA and RNA to cause strand breaks and chain termination, these agents disrupt cell division and trigger apoptosis in rapidly dividing cells The class plays a fundamental therapeutic role in oncology, serving as fr...
