Japanese Encephalitis Virus
Mosquito-borne neurotropic flavivirus
causes severe central nerve system diseases
Divided into 4 Genotypes
For unknown reason genotypes 3 is the most outbreak
Culex tritaeniorhynchus is the important vector

Report
From Novartis
Den 2 protease can be activated by Den123 WNV and YFV NS2B(H)
From Jan LR et al 1995
Den 4 protease canrsquot be activated by JEV NS2B(H) but JEV protease can activated by Den 4 NS2B(H)
12
From the different on NS2B(H)-NS3 protease complex structure and cofactor specificityCan we do the NS2B cofactor analog as an universal drug for flavivirus

Den 2 protease can be activated by Den123 WNV and YFV NS2B(H)
From Jan LR et al 1995
Den 4 protease canrsquot be activated by JEV NS2B(H) but JEV protease can activated by Den 4 NS2B(H)

From the different on NS2B(H)-NS3 protease complex structure and cofactor specificityCan we do the NS2B cofactor analog as an universal drug for flavivirus
