摘要:
Antibiotic penem compounds are represented by the following formula: ##STR1## wherein R represents a group of the general formula: ##STR2## in which R.sub.1 is a hydrogen atom or linear or branched C.sub.1 --C.sub.6 alkyl group, R.sub.2 is a particular substituted or unsubstituted alkyl, aryl or aralkyl group, n is an integer of 1-6, Y is a 5- or 6-membered heterocyclic aliphatic group having 1 or 2 oxygen atoms in the ring thereof, and Z is a specific 5-substituted 2-oxo-1,3-dioxolen-4-yl group. Antibiotic compositions for oral administration are also described.

摘要:
The invention relates to azetidin-2-ones of the formula ##STR1## wherein R.sub.a represents hydroxy-lower alkyl, R.sub.1 represents hydrogen, an organic radical bonded by a carbon atom to the ring carbon atom or an etherified mercapto group, R.sub.2.sup.A together with the carbonyl group to which it is attached is a protected carboxyl group and Z' is oxygen, sulfhur or an optionally substituted methylidene group, functional groups in the radicals R.sub.a, R.sub.1 and Z' optionally being in protected form. The azetidinones are useful intermediates for the preparation of penem antibiotics.

摘要:
Provided in the present invention are a cocrystal of piperacillin sodium and sulbactam sodium and preparation method thereof, as well as pharmaceutical compositions containing the same and uses thereof in treating infections caused by drug-resistant bacteria, such as a “super bacterium” producing NDM-1 and the like. The cocrystal of piperacillin sodium and sulbactam sodium contains diffraction angles of 14.24°, 16.58°, 16.79°, 17.77°, 19.20°, 20.21°, 20.39°, 23.06°, 27.86° and 32.16° represented by 2θ in an X-ray powder diffraction analysis spectrum.
摘要:
The present invention relates to a composition and method for the detection of a detectable product formed from a compound of the present invention in the body of an individual. The detectable product may include a halide or a benzenetriol-based or benzenetetrol-based product of a dehalogenation reaction in the presence of FROS. In many embodiments, an indigo-like product formed from an indigogenic compound of the present invention may also be a detectable product for diagnostic purposes. This indigo-like product may have a higher residence time in tissues where it is formed, thus providing a detectable product localized to sites of high FROS. An indigogenic compound containing one or more radioactive isotopes is further provided for therapeutic purposes.
