Abstract
BACKGROUND/AIM MST-16 and VP-16, both of which are topoisomerase II inhibitors, are antitumor agents regularly used to treat malignant lymphoma and small cell lung carcinoma. New therapeutic agents for tumor stage mycosis fungoides (MF) have recently been developed, but their efficacy is limited. We herein retrospectively reported the use of MST-16/VP-16 combination therapy for tumor stage MF at multiple treatment centers and examined their antitumor effect. METHODS Five male and four female patients with tumor stage MF were enrolled. Age at the start of therapy ranged from 33 to 80 years (average: 54.5 years), and the previous treatment consisted of R-CHOP, CAVOP-IFN, etc. The protocol for low-dose MST-16/VP-16 combination chemotherapy consisted of 800 mg MST-16 and 25 mg VP-16 administered 5 days per month. RESULTS Three of the 9 patients died, but two of the three fatalities were unrelated to MF. A treatment effect was seen in three and 6 patients who showed a complete response and a partial response, respectively. The 5-year and 10-year overall survival rate was 85.7% and 57.1%, respectively. Adverse reactions consisted of 4 cases of nausea and 1 case of leukopenia. CONCLUSION The present study demonstrated that the response rate to MST-16/VP-16 combination therapy was 100% and that the treatment effect was relatively long, suggesting that this therapy may be a viable option for treating tumor stage MF.

Abstract
Cardioprotective activity of dexrazoxane (ICRF-187), the only clinically approved drug against anthracycline-induced cardiotoxicity, has traditionally been attributed to its iron-chelating metabolite. However, recent experimental evidence suggested that the inhibition and/or depletion of topoisomerase IIβ (TOP2B) by dexrazoxane could be cardioprotective. Hence, we evaluated a series of dexrazoxane analogues and found that their cardioprotective activity strongly correlated with their interaction with TOP2B in cardiomyocytes, but was independent of their iron chelation ability. Very tight structure-activity relationships were demonstrated on stereoisomeric forms of 4,4'-(butane-2,3-diyl)bis(piperazine-2,6-dione). In contrast to its rac-form 12, meso-derivative 11 (ICRF-193) showed a favorable binding mode to topoisomerase II in silico, inhibited and depleted TOP2B in cardiomyocytes more efficiently than dexrazoxane, and showed the highest cardioprotective efficiency. Importantly, the observed ICRF-193 cardioprotection did not interfere with the antiproliferative activity of anthracycline. Hence, this study identifies ICRF-193 as the new lead compound in the development of efficient cardioprotective agents.

Abstract
Introduction: In Japan, etoposide or sobuzoxane, a type of topoisomerase II inhibitor, is orally administered in patients with lymphoma who cannot tolerate conventional combination chemotherapy. However, the related clinical data remain to be fully summarized.Areas covered: We evaluate the efficacy and toxicity of etoposide and sobuzoxane.Expert opinion: Previous studies on etoposide or sobuzoxane monotherapy, including those among patients who could not tolerate conventional chemotherapy, suggested a favorable overall response rate (ORR) with moderate gastrointestinal or liver/renal toxicity. As for adult T-cell leukemia/lymphoma, a clinical trial with a limited sample size exhibited an ORR of >70%. Remarkably, the percentage of patients with a poor performance status was high among those receiving etoposide/sobuzoxane. Given a lack of randomized studies, etoposide/sobuzoxane might be a therapeutic option for lymphoma in a palliative setting. In the future, prospective trials with a homologous treatment schedule are warranted, in which the association between clinical efficacy and characteristics of lymphomas, such as specific gene alterations, should be elucidated.

Abstract
As the aging society advances, the number of non-Hodgkin lymphoma (NHL) patients is
increasing. Aged relapsed or refractory (r/r) NHL patients have limited treatment options.
Therefore, a safe and effective regimen is urgently needed for these patients. Thus, we
originally developed the MTX-HOPE (methotrexate, hydrocortisone, vincristine, sobuzoxane,
and etoposide) regimen for r/r NHL and validated the safety and efficacy of this regimen
in a clinical setting. We analyzed the data of 42 r/r NHL patients who received MTX-HOPE
in this single-center retrospective cohort study. The median age of the patients was 81
years. The overall response rate was 45.3%. The median overall survival (OS) was 7 months,
the one-year OS was 43.7%, and the two-year OS was 40.8%. Grade ≥3 neutropenia and renal
dysfunction were observed in 47.6% and 11.9% of patients, respectively, and
treatment-related death were not observed. Appropriate supportive care enabled these
patients to continue the MTX-HOPE regimen. The proportion of patients who needed
hospitalization during MTX-HOPE therapy was only 21.4%. Multivariable analyses with the
Cox proportional hazards model revealed that both OS and progression-free survival (PFS)
were significantly influenced by high Ki-67 expression in pathology, with response to the
MTX-HOPE regimen after three to five cycles as a time-dependent covariate. Our results
suggest that MTX-HOPE therapy can be an option for non-aggressive r/r NHL patients. To
validate MTX-HOPE therapy, further prospective investigation is needed.

Abstract
The clinical use of bleomycin is limited by a dose-dependent pulmonary toxicity. Bleomycin is thought to be growth inhibitory by virtue of its ability to oxidatively damage DNA through its complex with iron. Our previous preclinical studies showed that bleomycin-induced pulmonary toxicity can be reduced by pretreatment with the doxorubicin cardioprotective agent dexrazoxane. Dexrazoxane is thought to protect against iron-based oxygen radical damage through the iron chelating ability of its hydrolyzed metabolite ADR-925, an analog of ethylenediaminetetraacetic acid (EDTA). ADR-925 quickly and effectively displaced either ferrous or ferric iron from its complex with bleomycin. This result suggests that dexrazoxane may have the potential to antagonize the iron-dependent growth inhibitory effects of bleomycin. A study was undertaken to determine if dexrazoxane could antagonize bleomycin-mediated cytotoxicity using a CHO-derived cell line (DZR) that was highly resistant to dexrazoxane through a threonine-48 to isoleucine mutation in topoisomerase IIalpha. Dexrazoxane is also a cell growth inhibitor that acts through its ability to inhibit the catalytic activity of topoisomerase II. Thus, the DZR cell line allowed us to examine the cell growth inhibitory effects of bleomycin in the presence of dexrazoxane without the confounding effect of dexrazoxane inhibiting cell growth. The cell growth inhibitory effects of bleomycin were unaffected by pretreating DZR cells with dexrazoxane. These results suggest that dexrazoxane may be clinically used in combination with bleomycin as a pulmonary protective agent without adversely affecting the antitumor activity of bleomycin.

Abstract
A Chinese hamster V79 cell-based assay for detection of topoisomerase II (topo II) poisons and catalytic inhibitors has been applied to study two bis(dioxopiperazine)s (ICRF-187 and ICRF-154) and a structurally distinct but related compound, merbarone. All three compounds have been previously characterized as being catalytic inhibitors of DNA topo II based primarily on in vitro studies with purified enzymes. The present studies indicate, to the contrary, that all three compounds are very potent DNA clastogens in V79 cells, by virtue of their ability to produce micronuclei, the formation of which is strongly antagonized under conditions in which DNA topo II is rendered catalytically inactive. None of the compounds could be demonstrated to possess catalytic inhibitory activity in intact V79 cells under the conditions tested. These studies provide biological evidence that bis(dioxopiperazine)s are capable of functional topo II poisoning in intact mammalian cells.

Abstract
Catalytic inhibitors of mammalian DNA topoisomerase II have been found recently in natural and synthetic compounds. These compounds target the enzyme within the cell and inhibit various genetic processes involving the enzyme, such as DNA replication and chromosome dynamics, and thus proved to be good probes for the functional analyses of the enzyme in a variety of eukaryotes from yeast to mammals. Catalytic inhibitors were shown to be antagonists against topoisomerase II poisons. Thus bis(2,6-dioxopiperazines) have a potential to overcome cardiac toxicity caused by potent antitumor anthracycline antibiotics such as doxorubicin and daunorubicin. ICRF-187, a (+)-enantiomer of racemic ICRF-159, has been used in clinics in European countries as cardioprotector. Furthermore, bis(2,6-dioxopiperazines) enhance the efficacy of topoisomerase II poisons by reducing their side effects in preclinical and clinical settings. Bis(2,6-dioxopiperazines) per se among others have antitumor activity, and one of their derivatives, MST-16 or Sobuzoxane, bis(N1-isobutyloxycarbonyloxymethyl-2, 6-dioxopiperazine), has been developed in Japan as an anticancer drug used for malignant lymphomas and adult T-cell leukemia in clinics.
