N-desethyl Amodiaquine (hydrochloride)

N-desethyl Amodiaquine (hydrochloride) (DEAQ) is the major metabolite of the antimalarial compound aminodiaquine, produced by the action of cytochrome P450 isoform 2C8 ^[1]. N-desethyl Amodiaquine (hydrochloride) is an antiparasitic agent that is highly active against Plasmodium falciparum and can synergize with amodiaquine^[2]. N-desethyl Amodiaquine (hydrochloride) has inhibitory effects against strains V1/S and 3D7 with IC₅₀ values of 97 nM and 25 nM, respectively ^[3]. This product is provided as N-desethyl Amodiaquine hydrochloride.

In vitro, treatment with N-desethyl Amodiaquine (hydrochloride) significantly blocked viral replication in both Huh 7 and Vero E6 cell lines infected with Ebola virus, with IC₅₀ values in the low μM range ^[4]. Treatment of RAW264.7 cells with N-desethyl Amodiaquine (hydrochloride) (4, 8, 16, 33, 66 μM) for 1 h inhibited proteinase B activity in a dose-dependent manner^[5].
