Chelating Agents Library

Metal ions such as iron, copper, and zinc are essential for life. However, the excess of these elements in the human organism is considered a negative prognostic factor for many diseases. It could cause severe injuries to multiple systems: the nervous, respiratory, reproductive, and digestive tract. One of the most common ways of treatment of metal intoxication is the use of chelating agents.

Diversity Compound  Libraries for HTS

It is generally accepted that chemical diversity leads to diversity in bioactivity, hence majority high-throughput screening screening (HTS) efforts utilize compounds that are selected for being as unlike each other as possible. Highly diverse, optimized compound libraries improve the success of HTS by minimizing false positives and maximizing hit rates without significant increase in the library size.

Covalent Inhibitors Library

Covalent inhibitors targeting enzymes such as kinases or proteases for a long time were set aside due to the high reactivity and potential toxicity. However, covalent kinase inhibitors were recently successfully introduced as cancer therapeutics agents. Thus, the benefits of irreversible kinase inhibition appeared to surpass the potential risks of such drugs. Traditionally, the most targeted residue in the protein kinase active site is cysteine. Due to the low abundance of this residue, drugs targeting cysteine appear to be more selective and have a lower chance of appearing to be toxic. All covalent enzyme inhibitors must contain specific reactive group (covalent "warhead"), and alternatively to cysteine, other amino acid residues were proposed as targets for reactive small molecules as well.

Fsp3 Compound Library

Scientific community studying medical chemicals has become increasingly aware of the value of the physical and structural properties of molecules. It is now known that the molecules which follow Lipinski's rule of five are more likely to appear biologically active. Other thresholds for properties were also proposed, for example, topological polar surface area and rotatable bonds number. Following the work of Frank Lovering et al. "Escape from Flatland: Increasing Saturation as an Approach to Improving Clinical Success", which discovers saturation of chemical compounds as the measure of the likelihood of compounds to be biologically active, we created a library which comprises known thresholds of medical compounds and also contains highly saturated compounds.
