Three-component, one-pot synthesis of novel 2,4-substituted 5-azolylthiopyrimidine library for screening against anti-influenza virus A. Bioorg Med Chem Lett 2008; 18:1177-80. [PMID: 18160286 DOI: 10.1016/j.bmcl.2007.11.117] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2007] [Revised: 10/26/2007] [Accepted: 11/30/2007] [Indexed: 11/23/2022]
Abstract
A novel one-pot synthesis of 2,4-substituted 5-azolylthiopyrimidines is achieved by sequential Michael-addition of 3-iodochromones with mercaptoazole (or mercaptotriazoles) and then condensation with a variety of amidines. Compound A(1)B(6)C(1) exhibits a potent anti-influenza virus A activity with an IC(50) value of 21.56 mg/mL and SI value of 9.

Abstract
This experiment was designed to detect the antiviral activities of crude fruit extracts of wild Ribes nigrum L. (Kurokarin extract) against influenza virus types A and B. Kurokarin extract was prepared as follows: fruits of Ribes nigrum L. were heated at 50 degrees C in a heating tank, and then ground under anaerobic conditions. The extracts were centrifuged, and the supernatant fluid was filtered and sterilized by infrared rays. The crude extract was diluted with Eagle's minimum essential medium (MEM) and the solution was adjusted to a pH 7.2 with 0.1 N or 1 N NaOH. Proven anti-influenza virus effects of the extracts were shown. The concentration of extract required to inhibit the plaque formation of both IVA and IVB by 50% (IC(50)) was 3.2 microgram/mL. Both IVA and IVB were directly inactivated up to 99% by 10 microgram/mL of the extract at pH 2.8, and 95% to 98% by this dose at pH 7.2. The growth of IVA in cells treated with 10 and 100 microgram/mL of the extract for 6 h after infection was completely suppressed. Virus titres in culture fluids of the cells treated with 100 microgram/mL of Kurokarin extract for 1 h at 8 to 9 h after infection, were completely suppressed, indicating that the extract inhibited the virus release from the infected cells.

Abstract
Billions of people are infected with respiratory viruses annually. Infants and young children, the elderly, immunocompromised individuals and those debilitated by other diseases or nutritional deficiencies are most at risk for serious disease. There are few vaccines available for use against these viruses, and even where there are (influenza, measles and adenovirus), infections remain common. The continued prevalence of respiratory virus infections has lead to renewed efforts to find safe agents effective against the most medically important respiratory viruses: influenza, respiratory syncytial, parainfluenza, measles, rhino- and adenovirus.
