Spiro Library

Preferred format:
Desirable size of the custom library selection:
  • Mg
  • uMol

ChemDiv’s Spiro Library contains 20,563 small molecule chemically diverse compounds.

Spiro compounds, characterized by their unique structure of at least two molecular rings joined by a single common atom, stand out in the realm of drug discovery for their distinctive chemical and biological properties. In contrast to biphenyls, which do not have any connecting atoms, fused rings like decalin that are joined by two adjacent atoms, or bridged rings like norbornane that are linked by two non-adjacent atoms, spiro compounds are defined by this single atom junction, which creates new three-dimensional shapes. These can be either fully carbocyclic, composed entirely of carbon atoms, or heterocyclic, incorporating one or more non-carbon atoms, further diversifying their potential applications in medicinal chemistry.

The presence of spiro compounds across natural systems has not only provided valuable tool compounds for biomedical research but also served as versatile scaffolds for the development of therapeutic agents. Their unique structural features allow for the exploration of novel interactions with a broad spectrum of biological targets, including but not limited to the µ-opioid receptor, CRTH2 and TRPV1 receptors, chemokine CCR5, PLA2 receptor, T-type calcium channels, bradykinin B1 receptor, NOS-2, muscarinic M3 receptor, V1a receptor, aminoacyl/phenylalanyl-tRNA synthetase, xanthine oxidase, and Nav1.7 sodium channels. The diversity and specificity of these targets highlight the potential of spiro compounds to address a wide array of pathological conditions from pain management and inflammation to cardiovascular diseases and neurological disorders. The small molecule spiro compound library thus represents a rich resource for drug discovery efforts, offering unique chemical entities that can lead to the identification of novel drug candidates with optimized efficacy, selectivity, and pharmacokinetic profiles, paving the way for innovative therapeutic solutions.

The main benefits of our spiro library for drug discovery lie in the unique structural diversity and complexity these compounds offer, enabling the exploration of novel pharmacological spaces and interactions with a wide array of biological targets. The distinctive three-dimensional configurations of spiro compounds, characterized by their bicyclic systems joined by a single atom, provide unparalleled opportunities for the design of drugs with novel mechanisms of action and improved selectivity. This structural uniqueness can lead to enhanced binding affinity and specificity towards a diverse range of receptors, enzymes, and ion channels, facilitating the development of innovative therapeutic agents across various disease areas. Moreover, the inherent versatility of spiro compounds, including both carbocyclic and heterocyclic varieties, supports the discovery of new drugs with optimized pharmacokinetic and pharmacodynamic properties, thereby addressing unmet medical needs and contributing to the advancement of personalized medicine.
