Composition composed of ceftriaxone sodium and sulbactum sodium
The present disclosure provides a composition consisting of ceftriaxone sodium and sulbactam sodium, a pharmaceutical formulation comprising the same and the application thereof. The composition is characterized by having an X-ray powder diffraction pattern with peaks at specific angles. The pharmaceutical formulation according to the present disclosure have better antibacterial activity and stability compared with known compositions, and are thus very suitable for the treatment of bacterial infections, especially for the treatment of refractory urogenital system infections caused by Neisseria gonorrhoeae which has drug-resistance to a variety of antibiotics (-lactams, tetracyclines, macrolides, fluoroquinolones and aminoglycosides).

CRYSTALLINE FORMS OF HYDROXYNORKETAMINE
The present invention provides novel, stable, processable and pharmaceutically acceptable salt forms of 2R,6R-hydroxynorketamine or 2S,6S-hydroxynorketamine with high aqueous solubility.
Manufacture of 4,5,6,7-tetrahydroisoxazolo[5,4-c]pyridin-3-ol
The present invention relates to a process for synthesis of 4,5,6,7-tetrahydroisoxazolo[5,4-c]pyridin-3-ol abbreviated THIP, having the INN name gaboxadol, starting from pyrrolidin-2-one. The process comprises a new direct process to obtain the intermediate dimethyl 5-hydroxy-3,6-dihydropyridine-1,4(2H)-5 dicarboxylate or the intermediate diethyl 5-hydroxy-3,6-dihydropyridine-1,4(2H)-dicarboxylate.
Peptide-based proteasome inhibitors for treating conditions mediated by senescent cells and for treating cancer
The proteasome inhibitors of this invention include peptide-based compounds with a short linear sequence of amino acids. An oxo or thio group is attached to the N-terminal amino acid. A protein-reactive electrophilic group such as an epoxyketone, an aziridinylketone, or a beta-lactone is attached to the C-terminal amino acid. Upon contact with a proteasome complex in a target cell, the electrophilic group reacts with a functional group in or near a binding pocket or active site of the proteasome, forming a covalent bond and thereby inactivating the proteasome. These and other proteasome inhibitors can be screened for binding affinity and an ability to selectively eliminate senescent cells or cancer cells. Compounds that selectively remove senescent cells can be developed for the treatment of conditions such as osteoarthritis, ophthalmic disease, pulmonary disease, and atherosclerosis.
