Cyclotriazadisulfonamide (CADA) is a specific CD4-targeted HIV entry inhibitors. Cyclotriazadisulfonamide (CADA) inhibits the co-translational translocation of human CD4 (huCD4) into the ER lumen in a signal peptide (SP)-dependent way[1][2].
Cyclotriazadisulfonamide (CADA) significantly decreases the amount of cell surface CD4 -the main receptor for HIV -without altering the expression of any other cellular receptor examined so far[1].Cyclotriazadisulfonamide (CADA) exhibits an EC50 of 0.4 μg/mL for CD4 in MO-DC cells. Treatment of MO-DC with 10 μg/mL of CADA results in 83% downregulation of cell surface CD4, an effect that is similar to that observed for CADA treatment of CD4+ T cells[1].CADA prevents MT-4 cells from HIV-1 and SIV infection (EC50 are 0.7 and 1.2 g/ml, respectively)[1].
