A new antibiotic XK-62-2. III. The structure of XK-62-2, a new gentamicin C complex antibitic.

A new antibiotic victomycin (XK 49-1-B-2). II. Isolation, purification and physicochemical and biological properties.

A new antibiotic, victomycin, is active against a variety of Gram-positive and Gram-negative bacteria, and also has in vivo activity against solid Sarcoma 180 and Ehrlich ascites carcinoma. It belongs to the phleomycin-bleomycin group of antibiotics and has been differentiated from all known phleomycins and bleomycins by its physicochemical properties and thin-layer chromatograms.

Synthesis, Characterization, and Crystal Structure Determination of a New Copper(II) Complex: [H2en][Cu(pydc)2].2H2O

The new complex of [H2en][Cu(pydc)2].2H2O (1) (where H2en and pydc are ethylenediammonium and 2,6-pyridinedicarboxylate, respectively) was synthesized by the reaction of a mixture of ethylenediamine (en) and 2,6-pyridinedicarboxylic acid (H2pydc) in a mixture of CH3OH/H2O as solvent. This complex was fully characterized by elemental analysis, IR, UV–Vis spectroscopy as well as single-crystal X-...

The gentamicin antibiotics. 6. Gentamicin C2b, an aminoglycoside antibiotic produced by Micromonospora purpurea mutant JI-33.

A mutant strain of Micromonospora purpurea, designated var. JI-33, produced an antibiotic complex consisting primarily of gentamicin C1a. A further product of this fermentation was identical to a very minor component isolated from the fermentation of the parent organism and named gentamicin C2b. Physical measurements indicated its structure to be 6'-N-methylgentamicin C1a and this was confirmed...

Open MPI for Cray XE/XK Systems

Open MPI provides an implementation of the MPI standard supporting communication over a range of highperformance network interfaces. Recently, Oak Ridge National Laboratory (ORNL) and Los Alamos National Laboratory (LANL) collaborated on creating a port of Open MPI for Gemini, the network interface for Cray XE and XK systems. In this paper, we present our design and implementation of Open MPI’s...
