1,2-Αnnulated Adamantane Heterocyclic Derivatives as Anti-Influenza Α Virus Agents

Neuraminidase inhibitors as anti-influenza virus agents.

Influenza virus neuraminidase (NA) catalyses the cleavage of sialic acid residues terminally linked to glycoproteins and glycolipids and plays an important role in the replication of the virus. Recently, several potent NA inhibitors have been synthesized based on the rational design of mimicking the transition state of the sialic acid cleavage. Zanamivir and oseltamivir (GS 4104, the prodrug of...

New Anti-Influenza Agents: Targeting the Virus Entry and Genome Transcription

Introduction: The emergence and spread of the pandemic H1N1 influenza virus in 2009 indicates a limitation in the strategy to control the infection, despite a long-established vaccination programme and approved antivirals. Production the proper vaccine against influenza is difficult due to the genetic recombination of virus in the event of pandemic and co-circulation of drug-resistance variants...

Sinapic Acid Derivatives as Potential Anti-Inflammatory Agents: Synthesis and Biological Evaluation

Transcription factor NF-κB and relevant cytokines IL-6 and IL-8 play a pivotal role in thepathogenesis of inflammation. Sinapic acid is a natural product and was demonstrated to possessanti-inflammatory activity. In this paper, we synthesized a series of sinapic acid derivativesand evaluated their anti-inflammatory effects. The result suggested that all of the targetscompounds 7a-j inhibit NF-κ...

Novel Levofloxacin Derivatives as Potent Antibacterial Agents

In this report, a new series of fluoroquinolone agents which was derived from levofloxacin was synthesized and evaluated against Gram-positive (Bacillus subtillis, Staphylococcus aureus, Staphylococcus epidermidis and Micrococcus luteus) and Gram-negative (Esherichio coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Serratia marcescens) organisms. The results showed that some of the synth...
