  • Patent number: 5744634
    Abstract: A process for the manufacture of methyl or ethyl 2-keto-L-gulonate by esterifying 2-keto-L-gulonic acid with methanol or ethanol continuously in the presence of an acidic ion exchanger in the temperature range between room temperature and about 80.degree. C. and with average residence times between about 10 and about 120 minutes and with superficial velocities of about 0.5 m/h to about 7.5 m/h. The esterification is advantageously carried out under slight over-pressure. The thus-manufactured esters are important intermediates for the synthesis of vitamin C and the respective esterification product can be converted directly into vitamin C by lactonization.

  • Patent number: 5652353
    Abstract: It is an object of this invention to provide a human Tumor Necrosis Factor mutein or a pharmaceutically acceptable salt thereof characterized in that the TNF sequence is changed by a deletion, insertion, substitution or combinations thereof, of one or more amino acids so that the mutein shows a significant difference between its binding affinity to the human p75-Tumor-Necrosis-Factor-Receptor and to the human p55-Tumor-Necrosis-Factor-Receptor. The invention also includes DNA sequences coding for such muteins, vectors comprising such DNA sequences, host cells transformed with such vectors and a process for the production of such muteins employing such transformed host cells and pharmaceutical compositions containing such muteins and their use for the treatment of illnesses, for example cancer.

  • Patent number: 5648550
    Abstract: A novel process for the manufacture of .beta.-keto alcohols from aldehydes comprising reacting a conjugated polyene aldehyde under basic conditions with a cyclocarbonate or derivative thereof. Certain carotenoid products of this process are novel compounds and are also an object of the present invention.

  • Patent number: 5591840
    Abstract: The present invention is directed to oligodeoxynucleotides which are capable of hybridizing to genes which encode NF-.kappa.B. The oligodeoxyribonucleotides are antisense to NF.kappa.B genes and when hybridized prevent the production of NF.kappa.B transcription factor by the NF.kappa.B genes, and thereby provide a means for preventing cellular adhesion.

  • Patent number: 5571920
    Abstract: Novel alcohols of the formula ##STR1## wherein R.sup.a is azido or phthalimido, R.sup.4 is alkyl, cycloalkyl, cycloalkylalkyl, aryl or aralkyl, R.sup.7 and R.sup.8 together are a trimethylene or tetramethylene group which is optionally substituted by hydroxy, alkoxycarbonylamino or acylamino or in which one --CH.sub.2 -- group is replaced by --NH--, --N(alkoxycarbonyl)--, --N(acyl)-- or --S-- or which carries a fused cycloalkane, aromatic or heteroaromatic ring, and R.sup.9 is alkoxycarbonyl, monoalkylcarbamoyl, monoaralkylcarbamoyl, monoarylcarbamoyl or a group of the formula ##STR2## in which R.sup.10 and R.sup.11 each is alkyl, are described along with a process for their manufacture.
