It applied the basic principles of nuclear magnetic resonance (NMR) spectroscopy, which provides both chemical and physical. Arvin Moser 1 Brent G Pautler 1 10.1002/mrc.4453 Abstract The successful elucidation of an unknown compound's molecular structure often requires an analyst with profound knowledge and experience of advanced spectroscopic techniques, such as Nuclear Magnetic Resonance (NMR) spectroscopy and mass spectrometry. Magnetic resonance imaging is a widely used noninvasive medical imaging technique to visualize the inner part of human body. 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. Chemistry Sol Man E7MARTIN R SCOTT, Picturing Migrants: The Grapes of Wrath. 1H NMR analysis of urine samples from prostate biopsy patients with and without PCa identifies several metabolites, including lactate and hippurate, that are significantly altered in PCa. Diffusion Ordered Spectroscopy (DOSY) NMR - Interpretation. Furthermore, LSD with direct 2 bond NMR experimental data is a reliable CASE technique for identification of cembranoid compounds. 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. 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.
