COA of Formula: C17H10ClF3N2O3

Trovafloxacin, a novel broad spectrum antibacterial, contains the unusual (1alpha,5alpha,6alpha)-3-azabicyclo[3.1.0]hexane ring system. The prototype of the industrial synthesis of this ring system and possible mechanistic pathways to exclusive formation of the exo or 6alpha-nitro derivative 4 are described, which leads to the key 6a-nitro-3-azabicyclo[3.1.0]hexane intermediate 10. The synthesis of 6a-amino-3-azabicyclo[3.1.0]hexane 16 and useful protected cxo 6-amino derivatives 15 and 17 follows from 10. These can be coupled with the 7-chloronaphthyridone 18 to yield protected trovafloxacin compounds 20-22 in good yield. The ethyl ester of trovafloxacin 21 can also be accessed from the product of coupling 19, derived from 18 and the exo 6-nitro-3-azabicyclo[3.1.0]hexane compound 12. Removal of protecting groups from 20-22 with methanesulfonic acid yields trovafloxacin mesylate from which trovafloxacin zwitterion 1 can be liberated with base treatment. Zwitterion l can also be prepared directly from 16 tosylate salt and naphthyridone-2-carboxylic acid 26. The Royal Society of Chemistry 2000.

Carbanions of alpha-haloalkyl aryl sulfones, sulfonates, and sulfonamides react with bicyclic heteroaromatic compounds (quinoxalines, naphthyridines, and 5-azaquinoxalines) according to two general pathways: vicarious nucleophilic substitution of hydrogen and/or bisannulation.In some cases other competitive reactions such as SNAr are observed.Factors governing the direction of these reactions are discussed in terms of the charge distribution in the anionic ? adducts and the reaction conditions.

The present study was designed to investigate the putative antidepressant-like activity of 7a, a 5-HT3 receptor antagonist, (although indirect evidence of 5-HT3 antagonism) with an optimal log P (3.35) and pA2 value (7.6) greater than ondansetron (pA2 – 6.6) using behavioural tests battery of depression. Acute treatment of 7a (0.5-2 mg/kg, i.p.) in mice produced antidepressant-like effects in forced swim test (FST) and tail suspension test (TST) without affecting the baseline locomotion in actophotometer test in mice. Moreover, the combination of a sub-effective dose of 7a (0.25 mg/kg, i.p.) and fluoxetine (5 mg/kg, i.p.) produced an anti-immobility effect in mouse FST. Pretreatment of mice with p-chlorophenylalanine methyl ester (PCPA; 100 mg/kg, i.p., an inhibitor of serotonin (5-HT) synthesis, for 4 consecutive days) and 1-(m-Chlorophenyl)- biguanide (mCPBG, 10 mg/kg, i.p., a 5-HT3 receptor agonist) prevented the anti-immobility effects of 7a (2 mg/kg, i.p.) in the mouse FST. In addition, 7a (0.5-2 mg/kg, i.p.) treatment also potentiated the 5-hydroxytryptophan (5-HTP) and pargyline induced head twitch response in mice. Furthermore, sub-chronic treatment (14 days) with 7a (0.5-2 mg/kg, i.p.) and paroxetine (10 mg/kg, i.p.) significantly attenuated the behavioural anomalies induced by bilateral olfactory bulbectomy in rats in a modified open field paradigm. These results suggest that the antidepressant-like action of 7a may be mediated by an interaction with the serotonergic system and this molecule should be further investigated as an alternative therapeutic approach for the treatment of depression.

A tricarboyanine derivative (IRPP) is applied as a ratiometric near-infrared chemosensor for detecting trivalent chromium ions (Cr3+) in living cells. Upon the addition of Cr3+ to a solution of IRPP, large-scale shifts in the emission spectrum (from 755nm to 561nm) are observed. In the newly developed sensing system, these well-resolved emission peaks yield a sensing system that covers a linear range from 1.0¡Á10-7 to 1.0¡Á10-5M with a detection limit of 2.5¡Á10-8M. The experimental results show the response behavior of IRPP towards Cr3+ is pH independent under neutral conditions (6.0-7.5). Most importantly, the fast response time (less than 3min) and selectivity for Cr3+ over other common metal ions provide a strong argument for the use of this sensor in real world applications. As a proof of concept, the proposed chemosensor has been used to detect and quantify Cr3+ in river water samples and to image Cr3+ in living cells with encouraging results.

4-Oxo-1,8-naphthyridine- and 4-oxoquinoline-3-carboxylic acids (2a, b and 3a-l) possessing a 1-aminocyclopropyl group at the 7-position have been synthesized and evaluated for in vitro antibacterial activities. The three quinolones (3d, h, i) exhibited potent antibacterial activities against both gram-positive and gram-negative bacteria, which are comparable to those of ciprofloxacin (CPFX) and ofloxacin (OFLX). Among the three compounds, the best pharmacological and pharmacokinetic profile was obtained with 3i, an OFLX analogue, which was considerably less toxic than three reference quinolones (1, CPFX, and OFLX).

Supramolecular polymers are polymeric arrays of monomeric units that are connected together via highly directional and reversible noncovalent interactions, resulting in polymeric properties in solution and the bulk. Because of the dynamic nature of the noncovalent interactions, supramolecular polymers show distinct properties such as reversibility, self-healing, stimuli-responsiveness and good processability. Here, we provide an overview of the fabrication of supramolecular polymers. We introduce the driving forces for supramolecular polymerization, summarize the topological structures of supramolecular polymers, and highlight the methods and strategies for the fabrication of supramolecular polymers in a controllable manner. It is evident that supramolecular polymers based on noncovalent interactions are complementary to traditional polymer science and represent a new growth point by marrying supramolecular science with polymer science.
