Novel glycopeptide antibiotic derivatives. These derivatives are represented by the formula (aglycon part of glycopeptide antibiotic derivative)-(Sac-NH)—RA [wherein (aglycon part of glycopeptide antibiotic derivative) is the part formed by removing the sugar part from a known glycopeptide antibiotic derivative; (Sac-NH) part is an amino sugar part or a sugar chain part containing an amino sugar; and RA represents, e.g., the formula —X1—Ar1—X2—Y—X3—Ar2 (wherein X1, X2, and X3 each represents 1) a single bond or 2) a heteroatom or heteroatom-containing group selected from the group consisting of —N═, ═N—, —NR1—, —O—, etc.; Y represents —NR2CO— or —CONR2— (wherein R2 represents hydrogen or lower alkyl), etc.)]. These derivatives have antibacterial activity against vancomycin-resistant bacteria.
摘要:
The present invention relates to hovel fused azolepyrimidine derivatives, processes for preparing them and pharmaceutical preparations containing them. The fused azolepyrimidine derivatives of the present invention exhibit enhanced potency for phosphotidylinositol-3-kinase (PI3K) inhibition, especially for PI3K-γ inhibition and can be used for the prophylaxis and treatment of diseases associated with PI3K and particularly with PI3K-γ activity. More specifically, the azole derivatives of the present invention are useful for treatment and prophylaxis of diseases as follows: inflammatory and immunoregulatory disorders, such as asthma, atopic dermatitis, rhinitis, allergic diseases, chronic obstructive pulmonary disease (COPD), septic shock, joint diseases, autoixnmune pathologies such as rheumatoid arthritis, and Graves' disease, cancer, myocardial contractility disorders, heart failure, thromboembolism, ischemia, and atherosclerosis. The compounds of the present invention are also useful for pulmonary hypertension, renal failure, cardiac hypertrophy, as well as neurodegenerative disorders such as Parkinson's disease, Alzheimer's disease, diabetes and focal ischemia, since the diseases also relate to PI3K activity in a human or animal subject.
