Fragment-Based Identification of Influenza Endonuclease Inhibitors.[Pubmed:27291165]
J Med Chem. 2016 Jul 14;59(13):6444-54.
The influenza virus is responsible for millions of cases of severe illness annually. Yearly variance in the effectiveness of vaccination, coupled with emerging drug resistance, necessitates the development of new drugs to treat influenza infections. One attractive target is the RNA-dependent RNA polymerase PA subunit. Herein we report the development of inhibitors of influenza PA endonuclease derived from lead compounds identified from a metal-binding pharmacophore (MBP) library screen. Pyromeconic acid and derivatives thereof were found to be potent inhibitors of endonuclease. Guided by modeling and previously reported structural data, several sublibraries of molecules were elaborated from the MBP hits. Structure-activity relationships were established, and more potent molecules were designed and synthesized using fragment growth and fragment merging strategies. This approach ultimately resulted in the development of a lead compound with an IC50 value of 14 nM, which displayed an EC50 value of 2.1 muM against H1N1 influenza virus in MDCK cells.

Together with the gamma-pyrone derivative, Pyromeconic acid (3-hydroxy-4H-pyran-4-one) and its beta-glucoside (erigeroside) were also isolated from the aerial parts of E. annuus.

Planta Med. 2002 Jul;68(7):664-6.
Three new pyrone glucosidic derivatives, together with the known Pyromeconic acid glucoside, three acytelenes and two eudesmanes, were obtained from the aerial parts of Conyza albida. The structures were elucidated by high field NMR spectroscopy.
[Isolation and structure of 6'-O-caffeylerigeroside from Erigeron multiradiatus].[Pubmed:12016944]
Yao Xue Xue Bao. 1998 Nov;33(11):836-8.
The plant, Erigeron multiradiatus (Wall.) Benth(Family: Compositae), is a perennial herb distributed abundantly in the mountainous area of the southwestern part in China. It is used in folk medicine for the treatment of common cold, panting cough, rheumatic, enteritis and toothache. In this paper, we report a new glycoside named as 6'-O-caffeylerigeroside isolated from Erigeron Multiradiatus (Family: Compositae) together with four known compounds. The known compounds were identified as Pyromeconic acid(I), scopoletin(II), 4-hydroxybenzoic acid(III) and vanillic acid(IV). The structure of 6'-O-caffeylerigeroside was elucidated as gamma-pyrone-3-O-[6"-(3',4'-dihydroxy-cinnamoyl)]-beta-D-glucoside(V) on the basis of chemical evidence and spectral data.
Two new glycosides from Vitex negundo.[Pubmed:23356826]
Nat Prod Res. 2013 Oct;27(20):1837-41.
Two new glycosides, 2-methyl Pyromeconic acid 3-O-beta-D-glucopyranoside-6'-(O-4''-hydroxybenzoate) (1), 6'-O-p-hydroxybenzoyl-gardoside (2) and four known iridoid glycosides (3-6) were isolated from the whole plant of Vitex negundo. Their structures were elucidated on the basis of spectroscopic methods including HR-ESI-MS, 1D and 2D NMR.
