Podsumowanie kontekstu i ogólnych celów projektu

Given the difficulty in drug discovery, in particular when protein-protein interactions are targeted, we proposed a innovative strategy to identify hits and lead compounds for non- or difficult-drugged targets. Such an approach could accelerate the drug discovery and enhance the possibility of success in launching novel therapy to suffering patients. In our research, this novel strategy was developed and validated, and is hopeful to be expanded to more targets.

Prace wykonane od początku projektu do końca okresu sprawozdawczego oraz najważniejsze dotychczasowe rezultaty

• Following the novel strategy proposed, corresponding pharmocophore models were established via a structure-based approach.
• As unforeseeable difficulty was encountered in targeting RAD51 and BRAC2, we switched our target to the protein interface between the α and β subunits of CK2. As this proposal focused on the development and validation of this innovative strategy, the change of target showed no influence on objectives and expected outcomings.
• Pharmacophore models of both targets were established.
• Based on the pharmocophore model established (described in previous report), five compound libraries were designed, virtually evaluated and synthesized.
• The Synthesized are evaluated for their ability to bind to the target and potency in disturbing Protein-protein interaction via X-ray crystallography and FP assays, which are currently still ongoing.

Innowacyjność oraz oczekiwany potencjalny wpływ (w tym dotychczasowe znaczenie społeczno-gospodarcze i szersze implikacje społeczne projektu)

The ability of discovering new drugs are expected to be further enhanced with the innovative strategy, i.e. pharmacophore guided diversity-oriented synthesis. After validation, this novel approach could be employed by other researcher as well and thus push the development of now therapies for unmet medical needs. Such a progress is welcome by suffering patents and their families and could also save hundreds of billions of public health costs.
