Summary
Nemorubicin (Methoxymorpholinyl doxorubicin) is a Doxorubicin derivative with potent antitumor activity. Nemorubicin is highly cytotoxic to a variety of tumor cell lines presenting a multidrug-resistant phenotype. Nemorubicin not only intercalate into the duplex DNA, but also result in significant ligands for G-quadruplex DNA segments, stabilizing their structure. Nemorubicin requirs an intact nucleotide excision repair (NER) system to exert its activity [1] [2] [3] [4] .
In Vitro
Nemorubicin has antitumor activity, with IC
70
s of 578 nM, 468 nM, 193 nM, 191 nM, 68 nM, and 131 ± 9 nM for HT-29, A2780, DU145, EM-2, Jurkat and CEM cell lines, respectively
[1]
.
Nemorubicin is CYP3A-activated anticancer prodrug, which can produce a more cytotoxic metabolite, PNU-159682
[1]
[2]
.
Nemorubicin acts through nucleotide excision repair (NER) system to exert its activity. Nemorubicin (0-0.3 μM) is more active in the L1210/DDP cells with intact NER than in the XPG-deficient L1210/0 cells. Cells resistant to nemorubicin show increased sensitivity to UV damage
[3]
.
Nemorubicin is cytotoxic to 9L/3A4 cells, with an IC
50
of 0.2 nM, 120-fold lower than that of P450-deficient 9L cells (IC
50
, 23.9 nM). Nemorubicin also potently inhibits Adeno-3A4 infected U251 cells with IC
50
of 1.4 nM. P450 reductase overexpression enhances cytotoxicity of Nemorubicin
[4]
.
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
Nemorubicin is converted to PNU-159682 by human liver cytochrome P450 (CYP) 3A4 in rat, mouse, and dog liver microsomes [2] . Nemorubicin (60 µg/kg) induces sifnificant tumor growth delay in scid mice bearing 9L/3A4 tumors, but shows no obvious effect on the tumor growth delay of 9L tumors in mice by i.v. or intratumoral injection (i.t.). Nemorubicin (40 µg/kg, i.p.) exhibits no antitumor activity and no host toxicity in mice bearing 9L/3A4 tumors [4] .
