The SAR studies revealed that the activity increased in order of conjugation of 2′ -amino group with carbamate > amide > urea derivatives. Lengthening the alkyl chain increased the cytotoxicity, the peak activity was found to around heptyl to nonyl substitutions. 2′-N-heptoxycarbonyl derivative 56 was found to be the most cytotoxic (IC50 = 0.76 μM) against HL-60 cells. Due to the interesting SARs of alkyl substitutions, we hypothesized that their location in the cell was different, and pursued a location study using 2′-(4?-pentynoylamino) 2′-deoxy-glucosyl OA, which suggested that these compounds distributed mainly in the cytosol. ? 2017 Elsevier Masson SAS |
