The title compound, {[CuCl2(PhTz)2] 0.5PhTz}n (PhTz is 1-phenyltetrazole, C7H6N4), has a polymeric structure, with uncoordinated disordered PhTz molecules in the cavities. The coordination polyhedron of the Cu atom is a highly elongated octahedron. The equatorial positions are occupied by two Cl atoms [CuÐCl = 2.2687 (9) and 2.2803 (7) AÊ ] and two N atoms of the PhTz ligands [CuÐN = 2.0131 (19...

The purpose of this study was to demonstrate that in vitro cell culture systems could serve a useful purpose in providing some guidelines in formulating drug schedules for combination cancer chemotherapy in the clinic. Using monolayer cultures of Chinese hamster ovary cells as the test system, we screened the combinations of 1-beta-D-arabinofuranosylcytosine (ara-C) + adriamycin, ara-C + 3,6 - ...

Streptomyces rugosporus LL-42D005 was shown to produce the novel pyrroindomycin antibiotics. Production of pyrroindomycin (alpha) and chloro-pyrroindomycin (beta) was characterized in a semi-defined fermentation medium containing glucose, casein, phosphate, vitamins and minerals. Accumulation of pyrroindomycin beta increased with increasing concentrations of glucose, reaching maximum titers at ...

The actions of diazepam and its p-chloro-derivative Ro 5-4864 were compared on mouse spinal cord and dorsal root ganglion neurons in cell culture. Diazepam enhanced but Ro 5-4864 reduced iontophoretic GABA responses in a concentration-dependent manner. Both diazepam and Ro 5-4864 limited sustained, high frequency repetitive firing of spinal cord neurons but diazepam was more potent. Ro 5-4864 w...

The presence of a neurogenic vasodilator mechanism was investigated in isolated bovine mesenteric arteries (BMAs) that were precontracted with phenylephrine. Electrical field stimulation induced tetrodotoxin-sensitive relaxations in guanethidine-pretreated BMAs. The relaxation occurred after a delay of about 5-8 seconds and amounted to 25-35% in different sets of experiments. The relaxation was...

With great interest we read the articles of Siu et al. [1] and Maindrault-Goebel et al. [2]. Both report on immediate type hypersensitivity reactions to oxaliplatin, occurring in about 10–15% of patients, mostly after several courses of therapy. We recently observed a quite different presentation of hypersensitivity to oxaliplatin, consisting of severe respiratory symptoms about 24 h after the ...

OBJECTIVE To review the efficacy of pharmacological prevention of serious reactions to iodinated contrast media. DESIGN Systematic review. DATA SOURCES Systematic search (multiple databases, bibliographies, all languages, to October 2005) for randomised comparisons of pretreatment with placebo or no treatment (control) in patients receiving iodinated contrast media. Review methods Trial qua...

1673 available suggests that convulsions are the only serious complication of acute zimeldine overdosage. [Sales of zimeldine in all countries were discontinued by Astra Pharmaceuticals in September 1983 because of the company's concern about reports of serious neurological side effects including the Guillain Barr6 syndrome.] I Dawling S, Braithwaite RA. Simplified method for monitoring tricycl...

The structures of two zinc complexes containing bidentate benzene-1,2-di-amine ligands are reported. (Benzene-1,2-di-amine-κ(2) N,N')di-chloro-idozinc, [ZnCl2(C6H8N2)], (I), displays a distorted tetra-hedral coordination sphere for the metal cation. The di-amine ligand and the Zn atom reside on a crystallographic mirror plane. In the 1:1 co-crystal salt trans-di-aqua-bis-(4,5-di-methyl-benzene-...
