Figure 7A shows that both compounds 2-Me and two get hydrogen bonds from residues Trp 102, Arg 112, and His 200 from the binding web site of EIF4E. Residues Trp 102 and Arg 112 participate also in – (as does Trp 56) and cation-interactions, respectively, with all the ligands. Moreover, GTA participates in hydrogen bonding with Gln 57, Trp 102, Glu 103, Arg 157, and Lys 162. Phe 417 and Phe 500 from the binding web site of 5-NT take part in – contacts with all ligands, as it can be seen in Figure 7B. Arg 40 and Asn 499 donate hydrogen bonds to both 2-Me and to two.

Docking research showed that KCCN1 is additional target for 1 and four, which indicates their probable multitargeting properties for the treatment of neurodegenerative disorders. Antiproliferative activity screening indicates that two and 2-Me would be the most potent anticancer agents amongst investigated compounds with superior activity than that with the constructive manage 5-fluorouracil. Docking studies point to 5-NT and EIF4E as you possibly can cancer-related targets. All investigated compounds showed significant antioxidant activities, far better than vitamin C in DPPH and ORAC assays. To conclude, our findings highlight the pharmacophore suitability of benzylidene-based (1,3-selenazol2-yl)hydrazones as novel MAO B/KCNN1 targeting compounds with outstanding antioxidative properties. This class also possess antiproliferative activity which may possibly be attributed to their robust binding to cancer connected targets 5-NT and EIF4E. Our additional investigation will be focused on experimental function to be able to confirm multi-targeting hypothesis.antioxidant-related assays; AL performed CV experiments and participated in evaluation and interpretation on the information; AV performed X-ray crystallographic analysis; JP performed anticancer associated experiments and particip.
