five-membered ring
Cyclopentane's skeletal shape
A five-membered ring is a cyclic molecular structure containing five atoms in its ring.
Common in organic chemistry, these rings form the backbone of many compounds—furan has oxygen in the ring, pyrrole has nitrogen, cyclopentane is all carbon.
The drug contains a five-membered ring with two nitrogen atoms.
