Finafloxacin, a fluoroquinolone antimicrobial agent from a new 8-cyano subclass, is most effective in slightly acidic environments (pH 5.0-6.0), a condition where other fluoroquinolones typically reduce in activity. It selectively targets bacterial type II topoisomerases, such as DNA gyrase and DNA topoisomerase IV, making it suitable for treating serious bacterial infections particularly in acidic contexts, including urinary tract infections (UTIs) and Helicobacter pylori infections.
Spirolaxine, a natural product isolated from Sporotrichum laxum ATCC 15155, has shown a variety of biological activities including promising anti-Helicobacter pylori property.

Zonisamide-13C2,15N is intended for use as an internal standard for the quantification of zonisamide by GC- or LC-MS. Zonisamide is an antiepileptic agent.1 It selectively inhibits the repeated firing of sodium channels (IC50 = 2 μg ml) in mouse embryo spinal cord neurons and inhibits spontaneous channel firing when used at concentrations greater than 10 μg ml.2 In rat cerebral cortex neurons, zonisamide (1-1,000 μM) inhibits T-type calcium channels with a maximum reduction of 60% of the calcium current.3 Zonisamide inhibits H. pylori recombinant carbonic anhydrase (CA) and the human CA isoforms I, II, and V with Ki values of 218, 56, 35, and 21 nM, respectively.4,5 In mice, it has anticonvulsant activity against maximal electroshock seizure (MES) and pentylenetetrazole-induced maximal, but not minimal, seizures (ED50s = 19.6, 9.3, and >500 mg kg, respectively). Zonisamide (40 mg kg, p.o.) prevents MPTP-induced decreases in the levels of dopamine , but not homovanillic acid or dihydroxyphenyl acetic acid , and increases MPTP-induced decreases in the dopamine turnover rate in mouse striatum in a model of Parkinson's disease.6 Formulations containing zonisamide have been used in the treatment of partial seizures in adults with epilepsy. |1.

Lacto-N-biose I, also known as Galβ1-3GlcNAc, is a naturally occurring metabolite that serves as a substrate for the α1,2-fucosyltransferase enzyme derived from Helicobacter pylori[1].
Antofloxacin is a well-tolerated, orally active, and broad-spectrum 8-amino-fluoroquinolone compound that exhibits potent antibacterial properties. It demonstrates superior activity against gyrA mutation-positive Helicobacter pylori strains, particularly in strains with mutations in the Asn87 position, when compared to levofloxacin. Additionally, Antofloxacin acts as a weak but reversible inhibitor of CYP1A2 and is clinically used to treat infections caused by various bacterial species.
Ecabet sodium (TA-2711) is a chemical compound utilized for the clinical treatment of gastrointestinal disease through the suppression of reactive oxygen species (ROS) generation and enhancement of Helicobacter pylori eradication [1]. Moreover, Ecabet sodium effectively attenuates apoptosis [2].
