We have been developing targeted medicinal agents since 2012. We use an integrated approach, bringing together specialists in the fields of molecular modeling, organic synthesis and molecular biology in one laboratory. Molecular docking, methadynamics, and molecular dynamics are all used to study the interactions of molecules with proteins and nucleic acids. Fine organic synthesis: we work with various classes of low molecular weight compounds, including synthesizing PROTAC. We use HPLC-MS, NMR, and instrument flash chromatography. Molecular biology: we work with bacteria and human tumor lines, carrying out a full cycle of substance testing – from MTT to highly informative screening, we work at the genomic and proteomic levels, we construct plasmids and cell lines. The main processes studied are programmed cell death, metabolic syndrome, and mechanisms of chemoresistance. We are implementing RPF projects, and we are publishing in Q1.

Development of MDM2-recruiting PROTACs
Parallel work is underway to create MDM2-rectracting PROTACs aimed at deactivating P-glycoprotein and autoubiquitinylation followed by MDM2 proteolysis. Protein targets have been studied in detail during the implementation of other projects. The synthesis methods were partially developed during the work on the creation of MDM2 inhibitors. Synthetic work is currently underway to assemble full-size PROTACs for subsequent testing.
