Med Chem 2020; 17:216-229. [PMID: 32520692 DOI: 10.2174/1573406416666200610191002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2019] [Revised: 02/20/2020] [Accepted: 03/04/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND A series of novel 5-substituted benzylidene rhodanine derivatives using four different amines were designed based on our previously developed CoMSIA (Comparative molecular similarity indices analysis) model for the anticancer activity. METHODS The designed rhodanines were synthesized via dithiocarbamate formation, cyclization and Knoevenagel condensation. The structures of the synthesized compounds were confirmed and analyzed by spectral studies. RESULTS The synthesized rhodanines were investigated for in vitro anticancer activities and the analogs have displayed mild to significant cytotoxicity against MCF-7 breast cancer cells. The compounds with benzyloxy substitution at the fifth position of rhodanine ring (Compounds 20, 33 and 38) system showed significant cytotoxic activity against MCF-7 cells. CoMSIA, a three-dimensional quantitative structureactivity relationship (3D-QSAR) technique was accomplished to elucidate structure-activity relationships. CONCLUSION Based on the information derived from CoMSIA contour plots, some key features for increasing the activity of compounds have been identified and used to design new anti-cancer agents. The present developed CoMSIA model displayed good external predictability, r2pred of 0.841 and good statistical robustness.

Abstract
Bacterial infections represent a significant health threat globally, and are responsible for the majority of hospital-acquired infections, leading to extensive mortality and burden on global healthcare systems. The second generation fluoroquinolone ciprofloxacin which exhibits excellent antimicrobial activity and pharmacokinetic properties as well as few side effects is introduced into clinical practice for the treatment of various bacterial infections for around 3 decades. The emergency and widely spread of drug-resistant pathogens making ciprofloxacin more and more ineffective, so it's imperative to develop novel antibacterials. Numerous of ciprofloxacin derivatives have been synthesized for seeking for new antibacterials, and some of them exhibited promising potency. This review aims to summarize the recent advances made towards the discovery of ciprofloxacin derivatives as antibacterial agents and the structure-activity relationship of these derivatives was also discussed.

The Current Case of Quinolones: Synthetic Approaches and Antibacterial Activity. Molecules 2016; 21:268.

Abstract
Quinolones are broad-spectrum synthetic antibacterial drugs first obtained during the synthesis of chloroquine. Nalidixic acid, the prototype of quinolones, first became available for clinical consumption in 1962 and was used mainly for urinary tract infections caused by Escherichia coli and other pathogenic Gram-negative bacteria. Recently, significant work has been carried out to synthesize novel quinolone analogues with enhanced activity and potential usage for the treatment of different bacterial diseases. These novel analogues are made by substitution at different sites--the variation at the C-6 and C-8 positions gives more effective drugs. Substitution of a fluorine atom at the C-6 position produces fluroquinolones, which account for a large proportion of the quinolones in clinical use. Among others, substitution of piperazine or methylpiperazine, pyrrolidinyl and piperidinyl rings also yields effective analogues. A total of twenty six analogues are reported in this review. The targets of quinolones are two bacterial enzymes of the class II topoisomerase family, namely gyrase and topoisomerase IV. Quinolones increase the concentration of drug-enzyme-DNA cleavage complexes and convert them into cellular toxins; as a result they are bactericidal. High bioavailability, relative low toxicity and favorable pharmacokinetics have resulted in the clinical success of fluoroquinolones and quinolones. Due to these superior properties, quinolones have been extensively utilized and this increased usage has resulted in some quinolone-resistant bacterial strains. Bacteria become resistant to quinolones by three mechanisms: (1) mutation in the target site (gyrase and/or topoisomerase IV) of quinolones; (2) plasmid-mediated resistance; and (3) chromosome-mediated quinolone resistance. In plasmid-mediated resistance, the efflux of quinolones is increased along with a decrease in the interaction of the drug with gyrase (topoisomerase IV). In the case of chromosome-mediated quinolone resistance, there is a decrease in the influx of the drug into the cell.
