If the bioactive molecule is a synthetic product, its structure may be rapidly deduced by a simple comparison of NMR parameters (often combined with MS) of the product relative to those of the known precursor, to see whether the desired chemical transformation has taken place. If the bioactive compound is an unknown molecule discovered in an active fraction in bioassay-guided screening, then the first step is to elucidate its structure. Typical molecules that form the basis of such natural products-based drug discovery studies include "organic" natural products as well as small peptides and proteins. The approaches to structure elucidation for natural products and peptides/proteins are a little different from each other and are described in turn. 

The goal of the research will be the conversion of targets into screens for potential small-molecule effectors of their function, or the determination of their molecular structures as a prelude to drug discovery studies. It is anticipated that the NCI may assist in these steps, as well as facilitating access to compound and natural product extract libraries, and the preclinical development of any promising leads discovered through the process.

Polymorphism is also known to affect solubility significantly. However, as at the discovery stage the crystalinity of the compounds is usually not investigated, this aspect is generally covered in the early development phase. This means that the solubility of the final drug substance is eventually lower than what is reported from initial drug discovery studies.
