Hydroxyl may not be indispensable for raltegravir: Design, synthesis and SAR Studies of raltegravir derivatives as HIV-1 inhibitors
摘要:
A series of raltegravir derivatives 20-42 were prepared and systematically evaluated for their anti-HIV activity. The bioassay results showed that most of the compounds possess good to excellent anti-HIV activity. Especially, compounds 25 and 35 with subpicomole IC50 values seemed to be the most potent anti-HIV agents among all of the reported synthesized compounds. These compounds may therefore be considered as new potent anti-HIV agents. The 5-hydroxyl modification of raltegravir derivatives significantly increased the anti-HIV activity, which indicates that the hydroxyl may not be indispensable for raltegravir. The introducing of acyl at 5-position of raltegravir derivatives is favorable for antiviral activity. In addition, a high-throughput cell-based assay method with pseudotyped virus stocks was developed and used to identify HIV inhibitors. (C) 2012 Elsevier Masson SAS. All rights reserved.

was designed and synthesized, and the target compounds were evaluated for their insecticidalactivity against five aphid species. Most of the tested compounds exhibited potent insecticidalactivity against Eriosoma lanigerum (Hausmann), Myzus persicae, and Aphis citricola. Compounds 20g and 24g displayed the highest activity against E. lanigerum, showing LC50 values of 27.6 and 30.4 μg/mL, respectively
