Synthesis of Quinolones and Zwitterionic Quinolonate Derivatives with Broad-Spectrum Antibiotic Activity. Pharmaceuticals (Basel) 2022; 15:ph15070818. [PMID: 35890116 PMCID: PMC9315932 DOI: 10.3390/ph15070818] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Revised: 06/28/2022] [Accepted: 06/29/2022] [Indexed: 12/04/2022] Open
Abstract
Quinolones are one of the most extensively used therapeutic families of antibiotics. However, the increase in antibiotic-resistant bacteria has rendered many of the available compounds useless. After applying our prediction model of activity against E. coli to a library of 1000 quinolones, two quinolones were selected to be synthesized. Additionally, a series of zwitterionic quinolonates were also synthesized. Quinolones and zwitterionic quinolonates were obtained by coupling the corresponding amine with reagent 1 in acetonitrile. Antibacterial activity was assessed using a microdilution method. All the compounds presented antibacterial activity, especially quinolones 2 and 3, selected by the prediction model, which had broad-spectrum activity. Furthermore, a new type of zwitterionic quinolonate with antibacterial activity was found. These compounds can lead to a new line of antimicrobials, as the structures, and, therefore, their properties, are easily adjustable in the amine in position 4 of the pyridine ring.

Abstract
Gram-positive bacteria are responsible for a broad range of infectious diseases, and the emergency and wide spread of drug-resistant Gram-positive pathogens including MRSA and MRSE has caused great concern throughout the world. 4-Quinolones which are exemplified by fluoroquinolones are mainstays of chemotherapy against various bacterial infections including Gram-positive pathogen infections, and their value and role in the treatment of bacterial infections continues to expand. However, the resistance of Gram-positive organisms to 4-quinolones develops rapidly and spreads widely, making them more and more ineffective. To overcome the resistance and reduce the toxicity, numerous of 4-quinolone derivatives were synthesized and screened for their in vitro and in vivo activities against Gram-positive pathogens, and some of them exhibited excellent potency. This review aims to outlines the recent advances made towards the discovery of 4-quinolone-based derivatives as anti-Gram-positive pathogens agents and the critical aspects of design as well as the structure-activity relationship of these derivatives. The enriched SAR paves the way to the further rational development of 4-quinolones with a unique mechanism of action different from that of the currently used drugs to overcome the resistance, well-tolerated and low toxic profiles.

Abstract
We report the vibrational spectral analysis was carried out using FT-IR and FT-Raman spectroscopy for 1-(pyrid-4-yl)piperazine (PyPi). Single crystals of PyPi suitable for X-ray structural analysis were obtained. The acid-base properties are also reported. PyPi supported on a weak acid cation-exchanger in the single protonated form and this system can be used efficiently as the solid supported analogue of 4-N,N-dimethyl-aminopyridine. The complete vibrational assignments of wavenumbers were made on the basis of potential energy distribution. The HOMO and LUMO analysis is used to determine the charge transfer within the molecule and with the molecular electrostatic potential map was applied for the reactivity assessment of PyPi molecule toward proton, electrophiles and nucleopholes as well. The stability of the molecule arising from hyper-conjugative interaction and charge delocalization has been analyzed using NBO analysis. The calculated first hyperpolarizability of PyPi is 17.46 times that of urea.

Abstract
The screening of an in-house quinolones library against Mycobacterium tuberculosis (Mtb) H(37) Rv, followed by a first cycle of optimization, yielded 6-hydrogen-8-methyl derivatives endowed with good potency. The antitubercular activity also encompassed the bacteria in a non-replicating state (NRP-TB) with minimum inhibitory concentration values lower than those of the reference agent, moxifloxacin. Among the best compounds, 11w and 11ai, characterized by a properly substituted piperidine at the C-7 position, were active against single-drug-resistant (SDR-TB) Mtb strains, maintaining overall good potency also against ciprofloxacin-resistant Mtb. This study expands the body of SAR around antitubercular quinolones leading to reconsider the role played by the usual fluorine atom at the C-6 position. Further elaboration of the 6-hydrogen-8-methylquinolone scaffold, with a particular focus on the C-7 position, is expected to give even more potent congeners holding promise for shortening the current anti-TB regimen.

Abstract
The current anti-HIV treatments fail to completely eradicate the virus in HIV-infected individuals, mainly as a result of a small pool of latently infected cells. This issue, together with the emergence of multidrug-resistant viruses, clearly highlights the need to find additional strategies. An overview of the Tat-mediated transcription inhibitors 6-desfluoroquinolones (6-DFQs), identified by our group, is given in this review along with a critical appraisal of their advantages and drawbacks. Attempts are also made to place them within the context of new potential anti-HIV therapeutics. Due to their innovative mechanism of action, the 6-DFQs could be interesting candidates for use in association with the currently used cocktail of drugs. Their potential as antivirals deserves further investigation.

Abstract
The derivatization of the fluoroquinolone ciprofloxacin greatly increases its antimalarial activity by combining bioorganometallic chemistry and the prodrug approach. Two new achiral compounds 2 and 4 were found to be 10- to 100-fold more active than ciprofloxacin against Plasmodium falciparum chloroquine-susceptible and chloroquine-resistant strains. These achiral derivatives killed parasites more rapidly than did ciprofloxacin. Compounds 2 and 4 were revealed to be promising leads, creating a new family of antimalarial agents.

Abstract
This paper reports on the rational design of a series of new 6-fluoroquinolones by QSAR analysis against Toxoplasma (T.) gondii, their synthesis, their biological evaluation against T. gondii and Plasmodium (P.) spp., and their effect on Mycobacterium (M.) tuberculosis DNA gyrase and growth inhibition. Of the 12 computer-designed 8-ethyl(or methoxy)- and 5-ethyl-8-methoxy-6-fluoroquinolones predicted to be active against T. gondii, we succeeded in the synthesis of four 6-fluoro-8-methoxy-quinolones. The four 6-fluoro-8-methoxy-quinolones are active on T. gondii but only one is as active as predicted. One of these four compounds appears to be an antiparasitical drug of great potential with inhibitory activities comparable to or higher than that of trovafloxacin, gatifloxacin, and moxifloxacin. They also inhibit DNA supercoiling by M. tuberculosis gyrase with an efficiency comparable to that of the most active quinolones but are poor inhibitors of M. tuberculosis growth.

Photostability studies of these compounds indicate that compound 3 is photostable whereas compound 1 and in particular, compound 2 are rapidly photodegraded upon UVA irradiation, yielding a toxic photoproduct. Intracellular localization of these compounds has been evaluated by means of fluorescence microscopy using tetramethylrhodamine methyl ester and acridine orange, which are specific fluorescent probes for mitochondria and lysosomes, respectively. No co-staining was observed with lysosomal stain for all the test compounds. On the contrary compound 3 was found to be specifically incorporated in mitochondria. The compounds exhibited remarkable phototoxicity in two cell culture lines: human promyelocytic leukaemia (HL-60) and human fibrosarcoma (HT-1080). The quinolone-induced photodamage was also evaluated measuring the photosensitizing cross-linking in erythrocyte ghost membranes, the strand breaks activity and oxidative damage on plasmid DNA. The results show that these derivatives are able to photoinduce crosslink of erythrocytes spectrin, whereas do not significantly photocleavage DNA directly, but single strand breaks were observed after treatment of photosensitized DNA with two base excision repair enzymes, Fpg and Endo III respectively.

Abstract
The synthesis of four new computer-designed fluoroquinolones which have been predicted by QSAR analysis to be active against the protozoa Toxoplasma gondii is described. These compounds are inhibitory in vitro for T. gondii. One of these compounds has a remarkably high activity comparable to that of trovafloxacin. It combines the basic cyclopropyl-quinoline structure of gatifloxacin or moxifloxacin with the C-7 6-amino-3-azabicyclo[3.1.0]hexyl side chain of trovafloxacin. The four compounds are also inhibitory for blood stages of Plasmodium falciparum though at high concentration. These results confirm the potential of quinolones as anti-T. gondii and antimalarial drugs but also show that the QSAR models for T. gondii cannot be reliably extended for screening antimalarial activity.

Abstract
Pursuing our searches on quinolonecarboxylic acids we used a simple three-step one pot procedure to synthesize novel 1,7-disubstituted-6-nitroquinolones. The new derivatives were tested against Mycobacterium tuberculosis and Mycobacterium avium complex (MAC) as well as against both gram-positive and gram-negative bacteria. In vitro assays showed some derivatives were endowed with good inhibiting activities against tested mycobacteria. Some derivatives were also found more potent than ciprofloxacin and ofloxacin (used as reference drugs) against gram-positive bacteria.

Abstract
A representative set of potent antibacterial 6-desfluoro-8-methylquinolones, in which the C-6 fluorine atom is replaced by -NH(2) or -H, and their 6-fluoro counterparts, were investigated to evaluate their phototoxic potential and to explore the mechanism behind their phototoxicity. The capacity to photosensitize biological substrates (lipids, proteins, DNA) has been analyzed, as well as their photocytotoxicity on red blood cells and 3T3 murine fibroblasts. The results obtained show that the quinolones studied are able to photosensitize red blood cell lysis in an oxygen-dependent way and induce a high decrease in cell viability after UVA irradiation. A major correlation with phototoxicity lies in the structure of the individual antibacterials and their hydrophobicity; in particular, 6-amino derivatives are less phototoxic than corresponding unsubstituted and fluorinated compounds. Cellular phototoxicity was inhibited by the addition of free radical and hydroxyl radical scavengers (BHA, GSH and DMTU), suggesting the involvement of a radical mechanism in their cytotoxicity. A good correlation was observed between lipid peroxidation and phototoxicity, indicating that the test compounds exert their toxic effects mainly in the cellular membrane. Preliminary experiments on pBR322 DNA show that these derivatives do not photocleave DNA, differently from the two photogenotoxic fluoroquinolones, ciprofloxacin and lomefloxacin, used as reference compounds.

Abstract
A new 6-desfluoroquinolone derivative, characterized by the presence of a 6-hydroxyl group instead of the usual fluorine atom at the C-6 position, was synthesized with the aim to better understand the mechanistic role of the C-6 substituent in the quinolone/DNA/DNA-gyrase interaction. The antibacterial activity unambiguously shows that the hydroxyl group is a good substitute for the C-6 fluorine atom, especially against Gram-positive bacteria. On the contrary, it is a very weak inhibitor of the target DNA gyrase, displaying the highest IC50 value observed for all the C-6 substituted analogues. This behaviour could be explained on the basis of its DNA binding properties.

Abstract
The present study was designed to examine the ability of different quinolones to affect the seizure severity and the latency of development of chemical kindling produced by repeated treatment using a subconvulsant dose of pentylenetetrazole (PTZ). A group of mice (kindled control) were treated subcutaneously (s.c.) with vehicle + PTZ (30 mg/kg, three times a week) for 6 consecutive weeks and the changes in excitability associated with the kindling state were observed over the following 2 h. A second group of mice were injected intraperitoneally (i.p.) with the following quinolone derivatives, ciprofloxacin (ciprox), pefloxacin (peflox), ofloxacin (oflox), cinoxacin (cinox), nalidixic acid (nalidixic), 1-cyclopropyl-6-amino-7-tetrahydroisoquinoline-8-methyl-4-oxo-1,4-dihydr oquinoline-3-carboxylic acid (M5) and 1-cyclopropyl-7-tetrahydro-isoquinoline-8-methyl-4-oxo-1,4-dihydroquinol ine-3-carboxylic acid (MH5) at a dose of 20 mg/kg 15 min before receiving a subconvulsant dose of PTZ (30 mg/kg, s.c.). The results showed that pretreatment with some of the quinolones tested facilitated the development of kindling to PTZ-induced seizures. In particular, ciprox, peflox, oflox, M5 and MH5 derivatives variously increased the development of kindling to PTZ induced seizures, whilst cinox and nalidix did not significantly affect it. Additionally we determined whether the enhanced susceptibility of kindled mice only occurred after relatively short intervals following the last seizure or whether it was a more permanent phenomenon. For the study of the persistence of kindling, the animals were rechallenged with the kindling stimulus (PTZ 25 mg/kg, s.c.) 15 and 30 days after the last injection of the chronic treatment with PTZ (30 mg/kg, s.c.) and the behavioural changes in the kindled mice were compared with the control ones (chronically treated with vehicle). The present data demonstrated that kindling produced long-lasting alterations, substantiating that epileptogenesis initiated by kindling renders the brain more susceptible to central nervous system (CNS) side effects of quinolones. An interaction between PTZ and quinolone derivatives which involves either an inhibition of gamma-aminobutyric acid (GABA) neurotransmission or/and an increase in the function of the excitatory amino acid (EAA) system is suggested.

Abstract
There have been several reports that convulsions, although rare, occur in patients who receive fluoroquinolones. In this study, the proconvulsant effects exhibited by a novel series of 6-desfluoroquinolones and some classic quinolones on pentylenetetrazole (PTZ)-induced seizures in mice were evaluated and compared. Animals were intraperitoneally injected with vehicle or quinolone derivatives (5 to 100 microg/g of body weight) 30 min before the subcutaneous (s.c.) administration of PTZ (40 microg/g). In each experiment, mice were then observed for 1 h to monitor for the incidence and onset of clonic seizures. The order of proconvulsant activity in our epileptic model was MF5184 > MF5187 > pefloxacin > MF5189 > ofloxacin > ciprofloxacin > MF5140 > MF5181 > MF5137 > rufloxacin > MF5143 > MF5158 > MF5191 > MF5128 > MF5138 > cinoxacin > MF5142 > norfloxacin > nalidixic acid. The relationship between the chemical structure and the proconvulsant activity of 6-desfluoroquinolone derivatives was studied. We observed that, in terms of toxicity to the central nervous system (CNS), besides the heterocyclic side chain (moiety) at the C-7 position, the C-6 substituent also appears to play an important role. In particular, a hydrogen at the C-6 position seemed to be responsible for major neurotoxic activity in comparison to an amino group located in the same position. The relationship between lipophilicity and proconvulsant activity was also investigated. We did not find any clear relationship between a higher level of lipophilicity and major proconvulsant properties. Although the principal mechanism by which quinolones induce potentiation of the proconvulsant effects of PTZ cannot be easily determined, it is possible that the convulsions are caused by drug interactions, because both PTZ and quinolones are believed to increase excitation of the CNS by inhibition of gamma-aminobutyric acid binding to receptors.

Abstract
The interaction of a number of novel 6-substituted quinolone derivatives with DNA in the presence/absence of magnesium ions has been investigated by fluorometric techniques. The drug-single-stranded nucleic acid interaction is invariantly mediated by the metal ion. In all cases optimal complex formation is found at physiological Mg2+ concentration. From titrations at different [Mg2+] the binding constant for the ternary drug-DNA-Mg2+ complex (KT) has been evaluated. Interestingly, a good relationship is found between KT and gyrase poisoning activity of the test quinolones (IC50), which confirms that DNA-affinity of the quinolone, modulated by Mg2+, plays an important role in poisoning the cleavable gyrase-DNA complex and, consequently, in eliciting antibacterial activity in this family of drugs. The results obtained with different 6-substituted compounds supports the idea that position 6 of the drug, besides playing a pharmacokinetic role, is involved in recognition of the enzyme pocket. Our data do not support a mechanism of action based upon quinolone intercalation into B-DNA.
