Abstract:
A novel crystal of (1R,5S,6S)-6-[(1R)-1-hydroxyethyl]-2-[(3S,5S)-5-sulfamoylaminomethylpyrrolidin-3-yl]thio-1-methyl-1-carba-2-penem-3-carboxylic acid or a hydrate thereof (hereinafter, abbreviated as doripenem). In the diffraction pattern in powder X-ray diffraction, the crystal has main peaks at diffraction angles(2?)=6.46,15.27,16.41,17.49,20.72,23.05 and 25.38(degrees)±0.1. At room temperature, the crystal is more thermodynamically stable, its dissolubility is higher, the crystal can be produced in industry with simple process and lower cost. A medicament composition containing the novel crystal of doripenem, preparation method and the uses in the manufacture of a medicament for the prevention of infection thereof.
Abstract:
A process of synthesizing a carbapenem compound of formula (6) is disclosed wherein R represents H or methyl, P and P* independently represent H or protecting groups and each R is independently selected from: H, halo, OH, OP wherein P is a protecting group, C1-6 alkyl or C1-6 alkyl substituted with 1-3 of halo, OH, OP, NH2, NHC1-4 alkyl or N(C1-4 alkyl)2.
Abstract:
The invention describes an improved process for synthesizing 1- beta -methyl-2-hydroxymethyl substituted carbapenems as key intermediates for the synthesis of anti-MRSA carbapenem antibiotics. The synthesis eliminates the use of BU3SnCH2OH and HMPA, which are toxic substances and not amenable to industrial scale production. The novel intermediates are also within the scope of this invention.
Abstract:
This invention described an ICE inhibitor prodrug (I) having good bioavailability. Compound of formula (I) is useful for treating IL-1 mediated diseases such as rheumatoid arthritis, inflammatory bowel disease, Crohn's disease, ulcerative colitis, inflammatory peritonitis, septic shock, pancreatitis, traumatic brain injury, organ transplant rejection, osteoarthritis, asthama, psoriasis, Alzheimer's disease, myocardial infarction, congestive heart failure, Huntington's disease, atherosclerosis, atopic dermatitis, leukemias and related disorders, myelodysplastic syndrome, uveitis or multiple myeloma.
Abstract:
A novel process for preparing a stabilized, lyophilized carbapenem, antibiotic formulation suitable for intravenous administration to patients in need thereof, wherein the active ingredient is of formula (II). The process entails compounding an unstable, monosodium salt carbapenem with a sodium bicarbonate solution at a temperature range of from about 0 DEG to about 5 DEG C while maintaining a pH between about 7.0 and about 8.0, filtering the resultant solution, bottling under sterile conditions, and lyophilizing to produce the formulation.
Abstract:
Novel crystalline carbapenem intermediate compounds of formula (I) wherein R1 represents CH3 or H; and P and P' independently represent H or a protecting group; and efficient process for synthesis thereof.
