Spiroindolins, commonly abbreviated to Spi13, form a class of chemical inhibitors characterized by a unique structure of spirocyclic indolins. This structural motif includes a bicyclic system in which a spiro carbon atom is shared between an indoline ring and another carbon-based ring, which can vary in size. The 13 in Spi13 is generally a reference to a specific target or series within the spiroindoline class, denoting a particular structural variant or defined set of substitutions that modulate the chemical properties of these compounds. The spiroindoline core is known for its rigid structure, which can confer a high degree of specificity in its interactions with various molecular targets. This rigidity is the result of spiro binding that locks the rings in place, reducing the conformational flexibility typically observed in nonspirocyclic compounds.

Spi13 inhibitors are synthesized through a variety of synthetic organic chemistry techniques, often involving spiro bond formation as a key step. This can be achieved through methods such as intramolecular cyclization reactions, in which a preformed indoline derivative undergoes a transition state leading to the spirocyclic structure. The tuning of Spi13 inhibitors involves modification of the indoline moiety or additional cyclic structure to achieve desirable physicochemical properties. Substituents on the Spi13 structure can vary widely, including, but not limited to, alkyl, aryl, heteroaryl, alkoxy, and halogen groups. Such modifications can drastically affect the binding affinity and selectivity of Spi13 inhibitors by altering factors such as molecular geometry, electronic distribution, and steric hindrances. As with many classes of chemical inhibitors, the design and synthesis of Spi13 compounds are often guided by detailed structure-activity relationship (SAR) studies, which help to understand how various chemical modifications affect the interaction of these molecules with their target sites.
