In general, this freeware-CASE is potential to be applied to other type of small molecule compounds and may serves as a potential solution for elucidation bottleneck step in Indonesian natural products studies. Magnetic HealthEdmund Shaftesbury, The immortality of the soulOliver Lodge.

79 The CASE software is used to generate and then filter through numerous permutations of structures that are. Furthermore, LSD with direct 2 bond NMR experimental data is a reliable CASE technique for identification of cembranoid compounds. Chemistry.Henry Watts, Introduction to Informetrics: Quantitative Methods. Magnetic Resonance in Chemistry 37(8): 538-544 Macdonald, J. Computer-assisted structure elucidation (CASE) is a technological development made in recent years to overcome obstacles in data interpretation such as that described above, and has further been utilized to revise some published structures associated with misinterpreted data sets. This may indicates that VLRC (Very Long-Range Correlations) affects significantly to LSD capability. The accuracy significantly enhanced (only 2-4 possible cembranoid structures from each NMR dataset) with addition of H2BC (Heteronuclear 2 Bond Correlation) experimental data. Here, a Nuclear Magnetic Resonance (NMR) approach, termed DREAMTIME, is introduced that provides 'a molecular window' inside complex systems, capable of showing only what the user desires, with. A strategy for the dereplication of a complete or a partial structure using (1)H NMR, (1)H- (13)C HSQC and (1)H- (1)H COSY spectral data, a molecular formula composition range and. Results of this study shows LSD generated numerous possible molecular structures, as the data input file derived only from 2D-NMR HMQC (Heteronuclear Multiple-Quantum Correlation), COSY (Homonuclear Correlation Spectroscopy), and HMBC (Heteronuclear Multiple Bond Correlation). 12 Nuclear Magnetic Resonance (NMR) dataset of cytotoxic cembranoids were used to evaluate the accuracy of LSD in generating the possible structures. This study presents the application of Logic Structure Determination (LSD), as a freeware Computer Assisted Structure Elucidation (CASE) for automatic molecular structure determination of cembranoid compounds from soft corals species.

However, manual structure determination into these compounds requires adequate knowledge of organic chemistry. The tropical Indonesian soft corals are a valuable resources that produce pharmacological cytotoxic cembranoids.
