| Bioactivity | Didanosine (2',3'-Dideoxyinosine; ddI) is a a potent and orally active dideoxynucleoside analogue, and also is a potent nucleoside reverse transcriptase inhibitor. Didanosine shows antiretroviral activity for HIV[1][2][3]. | ||||||||||||
| Invitro | Didanosine is converted by cellular enzymes to the active antiviral metabolite dideoxyadenosine triphosphate (dd-ATP) and the intracellular half life of dd-ATP varies from 8-24 hours[1].Didanosine shows antiretroviral activity with IC50 value of 0.24-0.6 mg/L for HIV infection[3].Didanosine (5, 10, 50, 100 ug/ml; 24, 48 h) shows no significant inhibition of cell proliferation in IEC-6 cells[2]. Cell Proliferation Assay[2] Cell Line: | ||||||||||||
| In Vivo | Didanosine (100, 150 mg/kg; p.o.; daily for 7 days) decreases the length of duodenal and in jejunal villus in mouse[2]. Animal Model: | ||||||||||||
