2008 Quantum's technology platform update and software releases

It has been an exciting year here in Quantum Pharmaceuticals, another great year for our highly effective small molecule drug discovery and ADMET platform development. Our work is firmly based in basic science: QUANTUM science team developed a vector field theory of water capable of describing numerous anomalous thermodynamic and dielectric of water, as well as interactions of biomolecules in aqueous environments (arXiv:0808.0991).

The progress in our understanding of biomolecules interactions led to further accuracy improvements in our major calculation routines (IC50, solvation energy, etc.). Speed increase and sophistication of the models employed in our simulations provided better ways for false positive elimination. Direct application of our software brought up novel inhibitors of HIV integrase and gp120 proteins, human neutrophyle elastase (HNE) (see collaborations). Massive computations made using Amazon EC2 computing platform let us develop new and refind existing ADMET models (see drug absorbtion prediction (arXiv:0810.2617) as an example).

All the scientific advances are plugged in and available through the following releases of Quantum sofware (sold separately and in packages at discount prices):

q-TOX - enables researches to compute toxic effects of chemicals solely from their molecular structure (LD50, MRDD, side effects) . The robust model is based on completely new approaches. While there are numerous commercially available toxicity prediction software, none offers the depth, scope and precision comparing to q-TOX. The paradigm in the q-TOX approach is based on the premise that biological activity results from the capacity of small molecules to modulate the activity of the proteome.

q-Mol - calculates such physicochemical parameters as Solubility in H2O (g/l); Solubility in DMSO (g/l); LogP, water/octanol; Mol weight; H-bond donors; H-bond acceptors; The number of rotatable bonds;Lipinski-rule-of-5.

q-ADME - For the first time we identified proteins, binding to which correlates well with FA and T1/2. This enabled us to simulate the active component of the ADME properties that has been the heel of Achilles for existing computational approaches still. The software predicts the following properties: Drug half-life (T1/2); Fraction of oral dose absorbed (FA); Caco-2 permeability; Volume of distribution (VD); Octanol/water distribution coefficient (LogP)

q-hERG - a unique and innovative software, which allows you to predict from a molecule structures of compounds their inhibition constants (IC50) for hERG channels.

q-Albumin software takes a molecular structure and calculates HSA binding constant by docking the molecule to both of the HSA active sites (Sudlow site I and Sudlow site II).
