Chemical Warfare Secrets Almost Forgotten: A Personal Story of Medical Testing of Army Volunteers

Chemical battle watchers, from scientists to coverage advocates, frequently ask yourself what went on on the military Chemical middle throughout the 1960's. It used to be a decade within which millions of military enlisted males served as volunteers for the secrets and techniques trying out of chemical brokers. the particular old checklist, despite the fact that, has earlier remained disturbingly incomplete.

Therefore, a drug discovery program usually starts with the discovery of lead compounds followed by their optimizations, instead of the impossible task of sifting through the entire chemical space directly for a drug compound. Even this two-step divide-and-conquer approach cannot divide the chemical space small enough for manual identification of desirable compounds. Library design as a drug discovery technology faces the same “finding-a-needle-in-ahaystack” issues as the drug discovery itself.

Building predictive QSAR/QSPR models is a process from experimental data to model and to predictions. Collecting reliable experimental data (and subdividing the data into training set and testing set) is the first step of the model-building process. The second step of the process is usually to select relevant parameters (or molecular descriptors) that are most responsive to the variation of activities (or properties) in the data set. The third step is QSAR/QSPR modeling and model validation. Finally, the validated models are applied to make predictions.
