“…The prototype of this class, the 2,4-dinitrobenzamide-chloromustard SN 23862 is a better NTR substrate than CB 1954, and provides a more efficient bystander effect, but lacks aqueous solubility and potency. 46,70 SN 28343 overcomes these limitations. In the present study, we insert NTR into the E3B region of ONYX-411, under viral transcriptional control, and use a novel NTR substrate (SN 29884) as a fluorescent probe to demonstrate expression of NTR with late kinetics (dependent on viral replication) in tumor cell cultures.…”

“…Entretanto, este problema pode ser solucionado quando Anlezark e colaboradores isolaram e purificaram uma nitrorredutase de Escherichia coli capaz de reduzir seletivamente o grupo nitro de (17), localizado na posição dois, a hidroxilamino 88,89 . A redução deste grupo nitro leva à ativação da mostarda e evita a formação de (21).…”

“…A redução deste grupo nitro leva à ativação da mostarda e evita a formação de (21). A partir de então, a mostarda (17) vem sendo estudada utilizando-se o sistema ADEPT (AntibodyDirected Enzyme Prodrug Therapy) 89 . Esta terapia fundamenta-se na ativação enzimática de um pró-fármaco usando um conjugado anticorpo-enzima (AEC) específico para antígenos presentes na membrana das células tumorais 90,91 .…”

“…18 Analogues of CB 1954 1 have also been prepared and studied as potential cytotoxic agents 19 as have the structurally related nitrogen-mustard derivatives SN 23862 5 and its analogues. [20][21][22][23][24][25][26] The 2-nitro-group in SN 23862 5 is reduced by E. coli NR producing the amine derivative 6 thus facilitating the formation of an aziridinium species 7 from the mustard moiety. In this Letter, we report the synthesis and evaluation (enzymatic and cytotoxicity) of a series of Nnitroarylated 1,2,3,4-tetrahydroisoquinoline derivatives with a core structure represented by formula 8 as potential nitroaromatic prodrugs.…”
