Hepatitis C virus (HCV) is a global health problem requiring novel approaches for effective treatment of this disease. The HCV NS5B polymerase has been demonstrated to be a viable target for the development of HCV therapies. β-d-2'-Deoxy-2'-α-fluoro-2'-β-C-methyl nucleosides are selective inhibitors of the HCV NS5B polymerase and have demonstrated potent activity in the clinic. Phosphoramidate ...
various aldoximes and ketoximes synthesis of corresponding aldehydes and ketones in the presence of sio2@feso4 nano composite as recoverable nano catalyst and nh2oh·hcl. the sio2@feso4 nano composite system was carried out between 10 to 15 min in oil bath (70-80 °c) under solvent-free condition in excellent yields in addition this protocol can be used for industrial scales. this method offers s...
Ferrocenyl-β-diketone ligands have been synthesised by the reaction of (ferrocenyl methyl) trimethyl ammonium iodide (FcCH2N Me3I ), where Fc=C5H5FeC5H4 – with sodium salt of -β-diketone [Na+CH-(COR1) (COR2), where R1= R2=CH 3, R1= CH 3 , R2=Ph, R1= R2=CMe 3 ]. The formula of the ligands (1-3) are FcCH 2 CH(COCH 3 )(COCH 3 ), FcCH 2 CH(COCH 3 )(COPh) and FcCH 2 CH(COCMe 3 ) 2 respectively. The ...
