analogue

 [an´ah-log]
1. a part or organ having the same function as another, but of different evolutionary origin.
2. a chemical compound having a structure similar to that of another but differing from it in respect to a certain component; it may have similar or opposite action metabolically. Also spelled analog.
nucleoside analogue a structural analogue of a nucleoside, a category that includes both purine analogues and pyrimidine analogues.
purine analogue a structural analogue of one of the purine bases(purine, adenine, or guanine); mercaptopurine and thioguanine are used as antineoplastics and azathioprine is an immunosuppressive. The antiviral agent vidarabine is an analogue of the adenine nucleoside adenosine.
pyrimidine analogue a structural analogue of one of the pyrimidine bases(cytosine, thymine, or uracil); fluorouracil and cytarabine are important antineoplastic agents.

an·a·logue

(an'ă-log),
1. A compound that resembles another in structure but is not necessarily an isomer (for example, 5-fluorouracil is an analogue of thymine); analogues are often used to block enzymatic reactions by combining them with enzymes (for example, isopropyl thiogalactoside vs. lactose).
2. One of two organs or parts in different species of animals or plants that differ in structure or development but are similar in function.
[G. analogos, proportionate]
