Pw. Smith et al., SYNTHESIS AND INFLUENZA-VIRUS SIALIDASE INHIBITORY ACTIVITY OF ANALOGS OF 4-GUANIDINO-NEU5AC2EN (GG167) WITH MODIFIED 5-SUBSTITUENTS, European journal of medicinal chemistry, 31(2), 1996, pp. 143-150
Analogues of 4-guanidino-Neu5Ac2en (GG167) have been prepared containi
ng alternative amide and sulfonamide substituents at the 5-position. r
ihydroxypropyl)-5,6-dihydro-4H-pyran-2-carboxylic acid 5 and rihydroxy
propyl)-5,6-dihydro-4H-pyran-2-carboxylic acid 6 were the only analogu
es which approached the activity of GG167, showing potent inhibition o
f influenza virus sialidases and good antiviral activity in vitro.
