literature review some curious inconsistencies in the free radical bromination of picolines were noted. To achieve a better understanding of the mechanisms and regioselectivity we reran these reactions, extending our work to unsymmetrical lutidines using N-bromosuccinimide in limiting amount. Characterization of the products was done with GC/MS and H NMR. The regioselectivity of bromination in unsymmetrical
在一篇文献综述中,人们注意到甲基吡啶的自由基溴化过程中存在一些奇怪的矛盾之处。为了更好地理解其机理和区域选择性,我们重新进行了这些反应,并使用有限量的N-溴代琥珀酰亚胺将工作扩展到不对称的二甲基吡啶。用GC / MS和1 H NMR对产物进行表征。在不对称的二甲基吡啶中溴的区域选择性表明环中的氮被感应失活。2,3、2,4和2,5二甲基吡啶对溴的竞争导致溴化在距离环中N最远的甲基中进行。3,4-亮氨酸仅显示4,4-二溴化产物。

), pharmaceutical compositions including the compounds, and methods of using the compounds and compositions for treating neurological disorders, psychiatric disorders, or a combination thereof.
The present invention relates to immune response modifiers of formula (I), which act selectively through agonism, of Toll-Like Receptors (TLRs), uses thereof, processes for the preparation thereof, intermediates used in the preparation thereof and compositions containing said inhibitors. These inhibitors have utility in a variety of therapeutic areas including the treatment of infectious disease such as Hepatitis (e.g. HCV, HBV), genetically related viral infection and cancer.
The invention provides compounds of Formula I and Formula II: A-B-C-D-E-F-G-J (I) C-D-E-F-G-J (II) wherein A, B, C, D, E, F, G, and J have any of the values defined in the specification, and salts thereof. The compounds are useful for inhibiting plasma kallikrein, and for treating a disease or condition in an animal where inhibition of plasma kallikrein is indicated.

The present invention relates to O-GIcNAc hydrolase (OGA) inhibitors. The invention is also directed to pharmaceutical compositions comprising such compounds, to processes for preparing such compounds and compositions, and to the use of such compounds and compositions for the prevention and treatment of disorders in which inhibition of OGA is beneficial, such as tauopathies, in particular Alzheimer's disease or progressive supranuclear palsy; and neurodegenerative diseases accompanied by a tau pathology, in particular amyotrophic lateral sclerosis or frontotemporal lobe dementia caused by C90RF72 mutations; or alpha synucleinopathies, in particular Parkinson's disease, dementia due to Parkinson's (or neurocognitive disorder due to Parkinson's disease), dementia with Lewy bodies, multiple system atrophy, or alpha synucleinopathy caused by Gaucher's disease.
