Photochemistry of 2-(4-hydroxystyryl)-1-naphthopyrylium.
Gavara R, Leydet Y, Petrov V, Pina F. Gavara R, et al. Photochem Photobiol Sci. 2012 Nov;11(11):1691-9. doi: 10.1039/c2pp25104c. Photochem Photobiol Sci. 2012. PMID: 22797713
In acidic medium and at room temperature the hydrolysis of the acetoxy derivative leads to the 2-(4-hydroxystyryl)-1-naphthopyrylium, in circa 2 days, [HCl] = 0.25 M. The pH dependent chemical reactions taking place with 2-(4-hydroxystyryl)-1-naphthopyrylium were determine …

Stromdahl EY, Nadolny RM, Gibbons JA, Auckland LD, Vince MA, Elkins CE, Murphy MP, Hickling GJ, Eshoo MW, Carolan HE, Crowder CD, Pilgard MA, Hamer SA. Stromdahl EY, et al. J Clin Microbiol. 2015 May;53(5):1697-704. doi: 10.1128/JCM.03454-14. Epub 2015 Mar 18. J Clin Microbiol. 2015. PMID: 25788545 Free PMC article.
In contrast, a recent publication by Clark and colleagues (K. L. Clark, B. Leydet, and S. Hartman, Int. J. Med. Sci. 10:915-931, 2013) reported detection of Lyme group Borrelia in A. americanum using a nested-flagellin-gene PCR. ...

The effect of self-aggregation on the determination of the kinetic and thermodynamic constants of the network of chemical reactions in 3-glucoside anthocyanins.
Leydet Y, Gavara R, Petrov V, Diniz AM, Jorge Parola A, Lima JC, Pina F. Leydet Y, et al. Phytochemistry. 2012 Nov;83:125-35. doi: 10.1016/j.phytochem.2012.06.022. Epub 2012 Aug 18. Phytochemistry. 2012. PMID: 22906883
For each anthocyanin, the thermodynamic and kinetic constants of the network of chemical reactions were calculated at different anthocyanin concentration, from 6 10-6 M up to 8 10-4 M; an increasing of the flavylium cation acidity constant to give quinoidal base and …

Polyanion inhibitors of HIV and other viruses. 7. Polyanionic compounds and polyzwitterionic compounds derived from cyclodextrins as inhibitors of HIV transmission.
Leydet A, Moullet C, Roque JP, Witvrouw M, Pannecouque C, Andrei G, Snoeck R, Neyts J, Schols D, De Clercq E. Leydet A, et al. J Med Chem. 1998 Dec 3;41(25):4927-32. doi: 10.1021/jm970661f. J Med Chem. 1998. PMID: 9836609
Only some compounds showed activity against the two HIV-2 strains (ROD and EHO) but at higher concentrations than those required to inhibit HIV-1 (IIIB and HE) replication. In addition, these compounds were not active against the M-tropic HIV-1 strain BaL but were active a …
