摘要:
The present invention relates to a compound of formula (I) wherein: wherein R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11 and G are as defined herein; and wherein the compound of formula (I) is optionally present as an agrochemically acceptable salt thereof. These compounds are thought to be suitable for use as herbicides. The invention therefore also relates to a method of controlling weeds, especially grassy monocotyledonous weeds, in crops of useful plants, comprising applying a compound of formula (I), or a herbicidal composition comprising such a compound, to the plants or to the locus thereof.
摘要:
Compounds, compositions, and methods comprising a polyamine compound are described, which may be used to kill, disperse, treat, reduce biofilms, and/or inhibit or substantially prevent biofilm formation. In certain aspects, the present invention relates to compounds, compositions, and methods comprising polyamine compounds that have antimicrobial or dispersing activity against a variety of bacterial strains capable of forming biofilms.
摘要:
Methods are disclosed for inhibiting or disrupting Janus tyrosine kinase 3 (Jak3) dependent function in cells of lymphoid or myeloid origin, especially for blocking proliferation and function of lymphocytes (e.g., T-cells, B-cells). A Mannich base compound, or a derivative or modified compound, is employed which is capable of selectively inhibiting Jak3 while affecting other protein tyrosine kinase activities to a lesser extent or not at all, to provide beneficial effects such as mitigation of transplant rejection and alleviation of allergic responses with fewer side effects than with conventional immunosuppressive agents.
摘要:
One aspect of the present invention relates to novel ligands for transition metals. A second aspect of the present invention relates to the use of catalysts comprising these ligands in transition metal-eatalyzed carbon-heteroatom and carbon-carbon bond-forming reactions. The subject methods provide improvements in many features of the transition metal-catalyzed reactions, including the range of suitable substrates, reaction conditions, and efficiency.

摘要:
Compositions comprising (±)-2-((dimethylamino)methyl)cyclohexanone, a transition-metal salt, and an organic solvent and methods of preparing (±)-cis-2-((dimethylamino)methyl)-1-(aryl)cyclohexanols, in particular (±)-cis-2-((dimethylamino)methyl)-1-(3-methoxyphenyl)cyclohexanol, are disclosed herein. In one embodiment, the (±)-2-((dimethylamino)methyl)cyclohexanone and transition-metal salt are in the form of a (±)-2-((dimethylamino)methyl)cyclohexanone:transition-metal salt complex. In another embodimemt, aryl is 3-methoxyphenyl.
摘要:
Provided is a glaucocalyxin A derivative, or salt thereof, as represented by the formula (I), a method for preparation of said glaucocalyxin A derivative, and a use for said glaucocalyxin A derivative in preparing pharmaceuticals for fighting autoimmune diseases and tumors, e.g. difficult-to-treat diseases such as systemic lupus erythematosus, psoriasis and triple-negative breast cancer
摘要:
Novel tricyclic-bis-enone derivatives (TBEs) as well as the process for the preparation of such TBEs are provided. Also provided are methods for prevention and/or treatment of cancer, Alzheimer's disease, Parkinson's disease, multiple sclerosis, amyotropic lateral sclerosis, rheumatoid arthritis, inflammatory bowel disease, and all other diseases whose pathogenesis is believed to involve excessive production of either nitric oxide (NO) or prostaglandins or the overexpression of iNOS or COX-2 genes or gene products. Further, methods for the synthesis of the TBE compounds of the invention utilize cheap commercially available reagents and are highly cost effective and amenable to scale-up. Additional high efficiency synthetic methods that utilize novel intermediates as well as the synthesis of these intermediates are also provided. Furthermore, the invention also provides methods for designing novel and water-soluble TBEs.
