Guided Ideographic Spin System Model Optimization (GISSMO)GISSMO enables the efficient calculation and refinement of spin system matrices (chemical shift and coupling constants) against experimental 1D-1H NMR spectra of small molecules.
GISSMO library:The library of parameterized compounds by GISSMO contains more than 1286 compounds, including many key mammalian metabolites (list of biolocations) and a library of drug-like molecular fragments used in ligand screening. The library covers simulations of 1H NMR spectra at a variety of magnetic fields (40, 60, 80, 90, 100, 200, 300, 400, 500, 600, 700, 750, 800, 900, 950, 1000, 1100, and 1300 MHz) and in addition the library provides spectral peak lists for every simulated spectra.
The exceptionally rich information content of NMR spectra is routinely used to identify and characterize molecules in a wide range of applications, including clinical biomarker discovery, drug discovery, environmental chemistry, and metabolomics. To facilitate seamless access to this reproducible and unique NMR metabolomics data library, every entry in the GISSMO library can be downloaded in NMR-STAR and NMReDATA data format.
The complete list of the entries in the GISSMO library can be accessed from “Global links->GISSMO Library”
GISSMO utilizes a graphical user interface (GUI) for guided optimization of spin system matrices that can be downloaded from the “Global links->GISSMO-GUI”.
