Synthesis and antitubercular activity of lipophilic moxifloxacin and gatifloxacin derivatives
摘要:
Fluoroquinolone (FQ) has a broad spectrum of activity against several bacteria, mycobacteria, parasites, and other diseases. Moxifloxacin and gatifloxacin are a new generation of fluoroquinolone agents with improved activity against Gram-negative and positive bacteria. As lipophilicity is an important consideration in the design and activity of novel antibacterial agents, we report in this work the synthesis and biological evaluation of 12 lipophilic moxifloxacin or gatifloxacin derivatives, by reaction of 1-cyclo-propyl-6,7-difluoro-1,4-dihydro-8-methoxy-4-oxoquinoline-3-carboxylic acid 13 with severals N-monoalkyl 1,2-ethanediamine or 1,3-propanediamine.

Selected substituted piperidine compounds are effective for prophylaxis and treatment of diseases, such as obesity and the like. The invention encompasses novel compounds, analogs, prodrugs and pharmaceutically acceptable salts thereof, pharmaceutical compositions and methods for prophylaxis and treatment of diseases and other maladies or conditions involving activation of the melanocortin receptor. The subject invention also relates to processes for making such compounds as well as to intermediates useful in such processes.
PIL, demonstrating competitive complexation between the ligand of the added copper(II) salt and the components of the ionicliquid to the copper(II) ion. The favorable mode of interaction of the present chelating PIL with the copper(II) ion was clarified based on a comparison of the interactions with analogous liquids, including the monoprotonated hexylaminium HHexam(Tf2N)-PIL, neat N-hexylethylenediamine
在质子离子液体(PIL)中溶剂化的铜(II)的精细和动态结构,质子离子液体包括单质子化的N-己基乙二胺(HHexen +)和双(三氟甲磺酰基)酰胺(Tf 2 N –)[或三氟乙酸盐(TFA –)]是使用NMR,可见电子和扩展X射线吸收精细结构(EXAFS)光谱测定的。阳离子单元中的螯合二胺基团有利于过渡金属盐在本发明的PIL中的有利溶解。通过向PIL中添加铜(II)盐来探索铜(II)离子与螯合二胺PIL的相互作用,表明所添加的铜(II)盐的配体与离子组分之间存在竞争性络合液体生成铜(II)离子。通过与类似液体(包括单质子化己基H己六胺(Tf 2 N)-PIL,纯净N)的相互作用进行比较,阐明了本发明螯合PIL与铜(II)离子相互作用的有利方式-己基乙二胺(Hexen)和纯乙二胺(En)。还研究了双-己烯和三-己烯铜(II)配合物在分子液体和固体中的配位模式,以比较铜(II)离子周围的配位结构与目前的PIL中的配位结构。由13

A series of divalent N‑alkylethylenediamine (alkyl‑en) metal(II) (alkyl = hexyl, 2‑ethylhexyl, octyl, dodecyl; metal = Ni, Cu, and Zn) complexes was prepared and their phase behavior was studied using differential scanning calorimetry. This kind of metalcomplexes is very useful for systematically investigating the relationship between phase behavior and molecular structures. It was found that several

The present invention provides phosphoryl choline derivatives of general formula (I), which are suitable to be immobilized on a solid support to provide a separation material, which bind with both high affinity and high specificity to a protein, more specifically to C-reactive protein and anti-phosphoryl choline antibodies. Said separation materials are particularly useful in the extracorporeal removal of C-reactive protein and anti-phosphoryl choline antibodies from a biological fluid of a patient for prophylaxis and/or treatment of immune dysfunctions and cardiovascular diseases. Also claimed is a device containing a column that comprises separation material made from formula (I)
wherein
L is a linker as defined in the claims;
X is selected from: -SH, -NHR3, -C=CH, -CH=CH2, -N3, -CHO.
