The administration of PEC to the animals with leukemia P388 increases the life span of the animals by 3.5 times (from 9.2 to 32 days) compared to the uncured control depending on the concentration of the introduced substance.

The selenium-containing phenolic antioxidant exhibited a higher activity than previously studied sodium 3-(3′-<i>tert</i>-butyl-4′-hydroxyphenyl)propylthiosulfate (TS-13). Like the sulfur-containing antioxidant TS-13, PEC induces oppositely directed changes in the activity of the studied cytostatics depending on the concentration: the change is potentiating for chemotherapy with CP and cPt and inhibiting for chemotherapy with Dox. It is most likely that the addition of the nitric oxide donor (NaNO<sub>2</sub>) to the studied compositions changes the redox potential of the cells, which affects the modulation of the activity of the cytostatics under study.

It compensates for the drawbacks of the existing SA modeling methods. The proposed approach was validated using five-membered aromatic heterocycles. Applying this algorithm significantly reduces the number of false positive predictions commonly encountered when employing traditional SA modeling methods.
