According to WHO, there is an urgent need for better antiviral drugs. Blocking viral hemagglutinin with multivalent N-acetylneuraminic acid derivatives is a promising approach to prevent influenza infection. Moreover, dual inhibition of both hemagglutinin and neuraminidase may result in a more powerful effect. Since both viral glycoproteins can bind to neuraminic acid, we have prepared three series of amphiphilic self-assembling 2-thio-neuraminic acid derivatives constituting aggregates in aqueous medium to take advantage of their multivalent effect. One of the series was prepared by the azide-alkyne click reaction, and the other two by the thio-click reaction to yield neuraminic acid derivatives containing lipophilic tails of different sizes and an enzymatically stable thioglycosidic bond. Two of the three bis-octyl derivatives produced proved to be active against influenza viruses, while all three octyl derivatives bound to hemagglutinin and neuraminidase from H1N1 and H3N2 influenza types.}, year = {2023}, eissn = {1422-0067}, orcid-numbers = {Herczeg, Mihály/0000-0002-7938-9789; Houser, Josef/0000-0003-4504-3891; Naesens, Lieve/0000-0001-9742-9302; Wimmerová, Michaela/0000-0002-7108-4198; Borbás, Anikó/0000-0001-8462-4547; Bakai-Bereczki, Ilona/0000-0003-4601-7257} } @article{MTMT:34316518, title = {Mannich-type modifications of (−)-cannabidiol and (−)-cannabigerol leading to new, bioactive derivatives}, url = {https://m2.mtmt.hu/api/publication/34316518}, author = {Lőrincz, Eszter Boglárka and Tóth, Gergely and Spolárics, Júlia and Herczeg, Mihály and Hodek, Jan and Zupkó, István and Minorics, Renáta and Ádám, Dorottya and Oláh, Attila and Zouboulis, Christos C. and Weber, Jan and Nagy, Lajos and Ostorházi, Eszter and Bácskay, Ildikó and Borbás, Anikó and Herczegh, Pál and Bakai-Bereczki, Ilona}, doi = {10.1038/s41598-023-45565-7}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {13}, unique-id = {34316518}, issn = {2045-2322}, abstract = {(−)-Cannabidiol (CBD) and (−)-cannabigerol (CBG) are two major non-psychotropic phytocannabinoids that have many beneficial biological properties.

Therefore, there is a great need for appropriate chemical modifications to improve their physicochemical and biological properties. In this study, Mannich-type reaction was used for the synthetic modification of CBD and CBG for the first time, and thus fifteen new cannabinoid derivatives containing one or two tertiary amino groups were prepared. Thereafter the antiviral, antiproliferative and antibacterial properties of the derivatives and their effects on certain skin cells were investigated.

The establishment of Pf resistance to most existing antimalarial therapies has complicated the problem, and the emergence of resistance to artemisinin derivatives is even more concerning. It is increasingly difficult to cure malaria patients due to the limited availability of effective antimalarial drugs, resulting in an urgent need for more efficacious and affordable treatments to eradicate this disease. Herein, new nucleoside analogues including morpholino-nucleoside hybrids and thio-substituted nucleoside derivatives were prepared and evaluated for in vitro and in vivo antiparasitic activity that led a few hits especially nucleoside-thiopyranoside conjugates, which are highly effective against Pf 3D7 and Pf RKL-9 strains in submicromolar concentration. One adenosine derivative and four pyrimidine nucleoside analogues significantly reduced the parasite burden in mouse models infected with Plasmodium berghei ANKA. Importantly, no significant hemolysis and cytotoxicity towards human cell line (RAW) was observed for the hits, suggesting their safety profile.
