Pyrazine diazohydroxide (NSC-361456) was identified as an active congener of pyridine 2-diazohydroxide with enhanced stability under physiologic conditions. In this phase I study, 35 patients with advanced cancer received 62 courses of PZDH administered intravenously every 3 weeks at doses ranging
Malignant melanoma is rapidly increasing in the United States. Metastatic disease responds poorly to currently available chemotherapy. Pyrazine diazohydroxide (PZDH) is a new agent inhibiting DNA synthesis that is active in mouse tumor models and human xenografts and lacks cross resistance with
Pyrazine diazohydroxide (PZDH) is a novel antineoplastic agent that appears to form DNA adducts via the reactive pyrazine diazonium ion and produces substantial antitumor activity in preclinical models. We conducted a phase I trial to determine the maximally tolerated dose of PZDH that could be
The sodium salt of pyrazine-2-diazohydroxide (PZDH; NSC 361456) was identified as an active congener of the antitumor lead pyridine-2-diazotate with enhanced chemical stability under physiological conditions. In a phase I trial of PZDH administered as a single i.v. bolus injection, 19 patients with
The effects of MK-212 [6-chloro-2-(1-piperazinyl)-pyrazine] (10, 20, and 40 mg, orally), a centrally acting serotonin (5-HT) receptor agonist and placebo, on serum cortisol, prolactin, and growth hormone levels were studied in eight healthy men over 3-hr. MK-212 produced a dose-related increase in
To examine further the serotoninergic system in obsessive-compulsive disorder (OCD), the plasma concentrations of cortisol and prolactin and the behavioral responses after oral administration of MK-212 (6-chloro-2-[1-piperazinyl]-pyrazine), a serotonin agonist, and placebo were studied in 17
The effects of 6-chloro-2-(1-piperaziny)pyrazine (MK-212), a centrally acting 5-HT1C/5-HT2 agonist, on body temperature and behavior were assessed using a single-blind cross-over design in 23 schizophrenic patients and 22 normal controls. Body temperature was assessed before drug administration and
