Glutathione (GSH) is an abundant cellular non-protein sulfhydryl that functions as an important protectant against reactive oxygen species and electrophiles, is involved in the detoxification of xenobiotics, and contributes to the maintenance of cellular redox balance. The rate-limiting enzyme in the de novo synthesis of glutathione is(More)
We conducted a phase I dose-escalation trial of perillyl alcohol (POH; NSC 641066) given p.o. on a continuous four times a day basis to characterize the maximum tolerated dose, toxicities, pharmacokinetic profile, and antitumor activity. Sixteen evaluable patients with advanced refractory malignancies were treated at the following doses: level 1 (L1), 800(More)
American Society of Clinical Oncology (ASCO), the leading medical professional oncology society, is committed to lessening the burden of cancer and as such will promote underused interventions that have the potential to save millions of lives through cancer prevention. As the main providers of cancer care worldwide, our patients, their families, and our(More)
The soy compound genistein has been observed preclinically to inhibit bladder cancer growth with one potential mechanism being the inhibition of epidermal growth factor receptor phosphorylation (p-EGFR). A phase 2 randomized, placebo-controlled trial investigated whether daily, oral genistein (300 or 600mg/d as the purified soy extract G-2535) for 14 to 21(More)
SCOPE Resveratrol (3,5,4'-trihydroxystilbene) is a phytoalexin shown to possess a multitude of health-promoting properties in pre-clinical studies. However, the poor in vivo bioavailability of resveratrol due to its rapid metabolism is being considered as a major obstacle in translating its effects in humans. In this study, we examined the hypothesis that(More)
Perillyl alcohol (POH; NSC-641066), a naturally occurring monoterpene, has shown antitumor and preventive activity in preclinical studies in rodent models. Drug-related activities that have been observed include the induction of apoptosis, cell cycle arrest, the inhibition of posttranslational modification of proteins that are involved in signal(More)
Perillyl alcohol (POH) has been shown to have both chemopreventative and chemotherapeutic activities in preclinical studies. The underlying mechanism(s) of action of POH have yet to be delineated but may involve effects on the transforming growth factor β (TGFβ) and/or the Ras signaling pathways. A phase I study of POH for 14 days out of every 28 days in(More)
PURPOSE A phase I dose-escalation trial of intravenous (IV) L-buthionine-SR-sulfoximine (BSO) with melphalan (L-PAM) was performed to determine the toxicity and biologic activity of BSO, administered as a short infusion every 12 hours, and the combination of BSO plus L-PAM. PATIENTS AND METHODS Twenty-eight patients with refractory malignancies received(More)
We conducted a phase II trial of doxercalciferol, a vitamin D2 analogue, in 15 patients with MDS. Each received doxercalciferol 12.5 microg orally daily for 12 weeks. Nine of 15 patients completed the prescribed course and of these, six had stable disease. No patient had a response (IWG criteria) and overall eight patients experienced progressive disease(More)
