6′-Aminospiro[cyclopentane-1,3′-indolin]-2′-one（Cat No.:L048702）is a spirocyclic compound featuring a cyclopentane ring fused to the 3-position of an indolin-2-one core, with an amino group at the 6′ position of the indoline ring. The spiro junction introduces conformational rigidity and three-dimensionality, which are desirable properties in drug design for improving target selectivity and pharmacokinetics. The amino group enhances reactivity and allows for further derivatization, such as amidation or acylation. This compound is commonly explored in medicinal chemistry for its potential as a bioactive scaffold in anticancer, antiviral, or CNS-active agents.
