Identifying therapeutic compounds based on their physical-chemical properties

Abstract

The present invention is directed to rapid and efficient methods of identifying therapeutic compounds by allowing only the most favorable molecules initially selected based on their physical-chemical profile falling within a range predefined by the physical-chemical / biological relationship of a previously tested small subset of compounds of same core structure to be assayed; and to the therapeutic compositions identified by said methods.

Benefits of technology

[0017]The present invention relates to a rapid and efficient method of identifying therapeutic compounds, by allowing only the most favorable molecules initially selected based on their core structure and their physical-chemical characteristics to be further assayed.

[0018]The present invention relates to a method of identifying molecules with a specific core structure selectively targeting certain disorders, based on their physical-chemical profile falling within a range predefined by the physical-chemical / biological relationship of a previously tested subset of compounds. In the present invention, members of a small subset of compounds with a specific core structure are tested for particular physical-chemical characteristics comprising their redox profile, and for their biological activity, a relationship between the two parameters is established, and other potential drug candidates are screened based on their physical measurements falling within a range predefined by said physical-chemical / biological relationship. If the physical-chemical profile is within the range defined by the relationship of physical-chemical and biological activity of the previously tested subset of compounds, they are subject to be considered therapeutic candidates. The physical property measurements may show better repeatability, reproducibility and lower variability over time than biological assays, and, since they do not involve living organisms, they may be less time-consuming and expensive.

Problems solved by technology

The limitation of such an approach is that it is possible to synthesize and test only a very small subset of all possible molecules thereby resulting in a high probability that the most efficacious molecules will be missed.

While widely used this method does not always yield active analogs indicating SAR alone may not be sufficient to warrant biological activity in all cases.

Although these methods are powerful they have serious limitations, such as the required amounts of target protein and the fact that the protein must be 15N-labeled to be useful for NMR studies.
