Introduction Fluoroquinolones FQs have emerged as a family of synthetic broad spectrum antimicrobial drugs, and the development of FQs was initiated in with the discovery of nalidixic acid. To date, several generations of FQs have been developed based on their antibacterial spectrum, which is getting significantly broader with each new generation, but there is no standard employed to determine which drug belongs to which generation [ 1 ].
The second and the third generations of FQs predominately act on Gram-negative bacteria, some Gram-positive bacteria, and intracellular microbes, while the latest fourth generation FQs are highly active against many species of Gram-positive pathogens, and anaerobic bacteria combined with the above mentioned microbes [ 2 ].
Currently, FQs are the second most widely used antimicrobial drugs, with extensive indications for infections including upper and lower respiratory infections, gastrointestinal infections, gynecologic infections, sexually transmitted diseases, prostatitis, and some skin, bone, and soft tissue infections, and their value and role in the treatment of bacterial infections continues to expand [ 134 ].
This invention provides estrogen receptor modulators of formula I, having the structure wherein R1, R2, R2a, R3, R 3a, and Arkoxy a prosztatitis, and X as defined in the specification, or a pharmaceutically acceptable salt thereof. A method of treating or inhibiting prostatitis or interstitial cystitis in a mammal in need thereof, which comprises providing to said mammal an effective amount of a compound of formula I, having the structure wherein R1 is alkenyl of carbon atoms; wherein the alkenyl moiety is optionally substituted with hydroxyl,--CN, halogen, trifluoroalkyl, trifluoroalkoxy,--CORS5 --CO2R 5,--NO2, CONR5R6, NR5R6 or N R5 COR6; R2 and R2a are each, independently, hydrogen, hydroxyl, halogen, alkyl of carbon atoms, alkoxy of carbon What is claimed is: 1. A method of treating or inhibiting arthritis in a mammal in need thereof, which comprises providing to said mammal an effective amount of a compound of formula I, having the structure wherein R1 is alkenyl of carbon atoms; wherein the alkenyl moiety is optionally substituted with hydroxyl,--CN, halogen, trifluoroalkyl, trifluoroalkoxy,--CORS5 --CO2R 5,--NO2, CONR5R6, NR5R6 or N R5 COR6; R2 d R2a are each, independently, hydrogen, hydroxyl, halogen, alkyl of carbon atoms, alkoxy of carbon atoms, alkenyl of carbon atoms, alkenyl of carbon.
These antimicrobial drugs act by binding two type II bacterial topoisomerase enzymes, DNA gyrase and topoisomerase IV, thereby inhibiting DNA replication and transcription: for arkoxy a prosztatitis Gram-negative bacteria, DNA gyrase is the target, whereas topoisomerase IV is the target for many Gram-positive bacteria [ 5 ].
It is believed that eukaryotic cells do not contain DNA gyrase or topoisomerase IV, while recent evidence has shown eukaryotic topoisomerase II is also a target for a variety of quinolone-based drugs [ 6 ].
Furthermore, FQs demonstrate potential anti-tuberculosis TB activity.
Although they are presently used to treat primarily in cases involving the resistance or intolerance to first-line anti-TB therapy by the World Heath Organization WHO [ 8 ], these drugs are potential first-line agents and are under study for this indication [ 9 ].
With increasing numbers of FQ prescriptions and the expanded use of these broad-spectrum agents, the selective pressure of FQ use results in the ready emergence of FQ resistance in a diversity of organisms, including Mycobacterium tuberculosis MTB and multidrug-resistant gram-positive bacteria, such as the methicillin-resistant Staphylococcus aureus MRSA.
For MTB, resistance is emerging and may herald a significant future threat to the long-term clinical utility of FQs [ 9 ]. On naproxen a prosztatitisből other hand, the extreme complexity and hydrophobicity of the cell envelop of mycobacteria is a barrier that prevents many agents from penetrating into the bacteria, and thus unable to access the intended targets.
To some extent, the lipophilicity of FQs plays an important role in their penetration into mycobacterial cells, and simply increasing the lipophilic character may also increase the anti-TB activity [ 101112 ].
KRONİK PROSTATİT TEDAVİSİ
Therefore, the strategy to increase the lipophilicity of FQs may lead to promising anti-TB candidates. The structure-activity arkoxy a prosztatitis SAR reveals that the introduction of the OMe group at the C-8 position of the FQ motif has resulted in a greater binding affinity to the topoisomerase IV enzyme, which results in enhanced activity against gram-positive pathogens and anaerobes while maintaining excellent potency against gram-negative organisms, as evidenced by gatifloxacin GTFX and moxifloxacin MXFX.
