Design, Synthesis, and Biological Evaluation of N-Alkylated Deoxynojirimycin (DNJ) Derivatives for the Treatment of Dengue Virus Infection
摘要:
We recently described the discovery of oxygenated N-alkyl deoxynojirimycin (DNJ) derivative 7 (CM-10-18) with antiviral activity against dengue virus (DENY) infection both in vitro and in vivo. This imino sugar was promising but had an EC50 against DENY in BHK cells of 6.5 mu M, which limited its use in in vivo. Compound 7 presented structural opportunities for activity relationship analysis, which we exploited and report here. These structure activity relationship studies led to analogues 2h, 2l, 3j, 3l, 3v, and 4b-4c with nanomolar antiviral activity (EC50 = 0.3-0.5 mu M) against DENY infection, while maintaining low cytotoxicity (CC50 > 500 mu M, SI > 1000). In male Sprague-Dawley rats, compound 3l was well tolerated at a dose up to 200 mg/kg and displayed desirable PK profiles, with significantly improved bioavailability (F = 92 +/- 4%).
