Putting Past Elucidations to Work for the Future of Antibacterial Research

Sequoia Sciences, Inc., recently purchased and implemented powerful software from ACD/Labs that will allow them to more easily elucidate chemical structures as well as to search and validate completed elucidated structures, effectively eliminating the need to reproduce the results in the future. This will allow Sequoia to better fulfill its mandate of discovering novel antibacterial compounds from plant materials.

Sequoia Sciences creates proprietary libraries of plant products and then uses high-throughput screening (HTS) techniques against biological targets in order to identify lead compounds. Once identified, the chemical structure of the lead compound is elucidated using an array of analytical techniques. Researchers and executives at Sequoia identified a need for a set of tools that would allow them to manage all of this data effectively—from uniformity of processing, to storage and databasing of the spectra and related data.

ACD/Structure Elucidator from Advanced Chemistry Development, Inc., (ACD/Labs) fit their needs perfectly. The software includes processing and databasing modules for 1D and 2D NMR spectra, MS, UV-IR, and chromatography data. NMR prediction and verification capabilities are also included. With this suite of tools, researchers can quickly determine whether the structure of a newly screened lead compound has been elucidated in the past, or use all of the available analytical data to determine the chemical structure of an unknown.

“We see it as a major competitive advantage, to be able to take the spectrum of a hit from HTS, and compare it against the database of previously elucidated structures,” said Mark O’Neil-Johnson, VP Analytical Chemistry, Sequoia Sciences, Inc. “It gives us the ability to move that lead through the development process, much, much faster, and with far fewer resources.“

ACD/Structure Elucidator unifies analytical data from an array of techniques and vendor formats so that incompatible file formats are not an issue.

“The choice was obvious for us,” O’Neil-Johnson further comments. “The combination of search capabilities, proton and carbon chemical shift predictors as well as the structure elucidation capabilities, meant that there was no hesitation in making this investment. Our previous experience with ACD/Labs products and service made for a seamless transition in adding additional modules.”

Infrared / IR SpectroscopyInfrared (IR) spectroscopy measures the interaction of infrared light with a sample, including transmission, reflectance & absorbance, facilitating the identification of analytes. Equipment used for quantitative analysis includes Fourier-transform infrared (FTIR) spectrometers, infrared cameras, FTIR gas analyzers, as well as attenuated total reflectance (ATR) accessories and pellet or film presses. Find the best IR spectroscopy products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place. Visit our product directory to receive quotes direct from the manufacturer. NMR and EPR SpectroscopyNuclear magnetic resonance (NMR) spectroscopy is used to resolve the local chemical environment of atomic nuclei with spin, revealing information on molecular structure, dynamic processes and chemical reactions of organic molecules, from proteins to synthetics. Electron paramagnetic resonance (EPR) also known as electron spin resonance (ESR) spectroscopy is used to detect and quantify paramagnetic species in a sample, including free radicals as transition metal ions. By immersing the sample in a strong magnetic field, both NMR and EPR spectrometers probe the sample with either radio waves or microwaves respectively. A range of benchtop, solid-state and time domain NMR spectrometers & EPR spectrometers are available, as well as NMR tubes, NMR solvents, software, coils, and magnets.

The two major instrument classes are single-beam or double-beam spectrophotometers. More specialized equipment includes colorimeters, spectroradiometers and refractometers. Portable and microvolume spectrophotometers are also available. For the modular spectroscopy lab, explore a range of light sources for combination with a spectrograph/spectrometer and optics.

Use HTS readers and integrated assay preparation / analysis workstations to screen your compounds. Identify active compounds against various HTS libraries, including membranes, proteins and peptides and HTS cell lines.

The software can be useful for graphical viewing, comparative analyses, high-throughput screening, genomics, proteomics and phylogenetics. Molecular recognition software uses bioinformatics tools and analyses such as BLAST searches and generates structural predictions, 3D structures and sequencing information.Compound LibrariesCompound libraries, or chemical libraries, are used in drug discovery for the identification of potential therapeutics compounds. Used in conjunction with high-throughput screening, the libraries of stored compounds are often generated for specific purposes as a drug target or disease model. Cheminformatics are commonly used when designing a compound library and software can be used to analyze the screening process.
