New potential chemotherapeutic strategies are required to overcome multidrug resistance (MDR) in cancer. This study investigated the anticancer effect of a novel anthracene derivative MHY412 on doxorubicin-resistant human breast cancer (MCF-7/Adr) cells. We measured cell viability and the expression
HL-37, a novel anthracene derivative, exhibited potent anticancer activity in many kinds of cancer cells. However, the exact mechanism and signaling pathway involved in HL-37-induced apoptosis have not been fully elucidated. Therefore, we explored the mechanisms of HL-37-mediated apoptosis in MCF-7
Forty-four patients with metastatic breast cancer who had previously received extensive conventional systemic therapy, including combination chemotherapy with doxorubicin, were treated with Bisantrene, a new anthracene derivative. The dose schedule was 250 to 300 mg/sq m body surface administered as
A human tumor cloning system has been utilized to culture 431 patients' breast cancer specimens. Overall, 288 or 67% of the specimens formed colonies in soft agar. Of the primary lesions 188/260 (72%) formed colonies and 100/171 (58%) of the metastatic lesions formed colonies. The median number of
New agents with increased activity and/or reduced toxicity are needed for the treatment of advanced breast cancer. The anthracene derivatives mitoxantrone and bisantrene had significant activity and acceptable toxicity in phase II trials. In an ongoing phase III trial we have now randomized 150
We have used a highly sensitive high-performance liquid chromatographic assay to evaluate the pharmacokinetics and tissue disposition of mitoxantrone, an investigational anthracene derivative which has shown significant activity during Phase II clinical trials in the treatment of metastatic breast
We have utilized a recently developed human tumor cloning system to screen for antitumor effects in vitro of a new anthracene derivative, CL216,942. The object was to determine whether the system is useful for pinpointing the types of tumors in patients which should be studied in early phase II
Vinorelbine (Navelbine) is a unique semi-synthetic vinca-alkaloid with a favorable safety profile that has demonstrated significant antitumor activity in patients with non-small cell lung cancer, advanced breast cancer, advanced ovarian cancer and Hodgkin's disease. The most common dose-limiting
