摘要:
The present invention relates to a novel group of compounds having antibiotic, antifungal and/or cytostatic properties, which are obtainable from myxobacteria, especially of the genus Sorangium, preferably Sorangium cellulosum. One representative of this group of compounds is currently named Disorazole Z and Disorazole Z-epoxide, respectively, with specific substituents and specific unsaturated bonds to its cyclic core structure:
摘要:
A chromium(VI)-free, chromium(III)-containing and substantially coherent conversion layer on zinc or zinc alloys presenting, even in the absence of further components such as silicate, cerium, aluminum and borate, a corrosion protection of approx. 100 to 1000 h in the salt spray test according to DIN 50021 SS or ASTM B 117-73 until first attack according to DIN 50961 Chapter 10; being clear, transparent and substantially colorless and presenting multi colored iridescence; having a layer thickness of approx. 100 nm to 1000 nm; and being hard, adhering well and being resistant to wiping.

A process for preparing 2-hydroxycarboxylic esters having a quaternary &bgr;-carbon atom by reaction of glycidyl esters with an organoaluminum reagent is described.
摘要:
The invention relates to compounds of the following general formula I ##STR1## especially the compound of formula Ia referred to as thiangazole ##STR2## their pharmaceutically acceptable acid addition salts, processes for their preparation and therapeutic compositions and compositions that can be used in crop-protection.
摘要:
The invention relates to novel polycyclic alkaloids of formula ##STR1## in which R.sup.1 represents hydrogen or hydroxy, R.sup.2 represents hydrogen or acyl and A and B, independently of one another, each represents C.dbd.O or C--OH, and wherein the dashed line represents a C.dbd.C double bond at the position of the middle bond when A or B represents C.dbd.O, or at the position of the two outer bonds when A or B represents C--OH, a process for the manufacture of these compounds by fermentation of a novel microorganism of the species Myxococcus xanthus, the novel microorganism itself, pharmacetical preparations that contain the novel compounds, and the use of the novel compounds as antibiotics and as tumour-inhibiting agents and for the manufacture of pharmaceutical preparations.
摘要:
Two improvements of a closed circuit television system applicable to a motor-freight tractor/trailer rig, or a motor vehicle, to see to the rear when the unaided view is obstructed, comprising:1. Sunvisor-mounted case (30), with a window (10), for cradling a camcorder-type LCD monitor (32), to provide protection for the monitor from heat, cold, vibrations, and bright sunlight, to allow a driver easy, direct, close-range viewing of the monitor screen, as if the screen were a rear-view mirror, while backing up a motor vehicle, or a tractor with attached trailer.2. Weather-proofed enclosure (40) for mounting on the reverse side of a plate (34), such as a license plate, located at the rear of a motor vehicle, or trailer, to protect a micro-video, pin-holed lens camera (48).These two improvements together meet a long-felt but unsolved need in the trucking industry.
