Virtual screening services

Quantum is a leading company providing drug screening services in-silico and, thus, delivering to it clients strong inhibitors against variety of target-proteins

We apply our proprietary developed computational technology QUANTUM, which shows outstanding accuracy in forecasting binding affinities. The hit rate of the QUANTUM performance is about 50%, it means that a half of found in silico strong inhibitors would be confirmed in in-vitro testing!!!
