Given a compound, how can we effectively predict its biol. function. It is a fundamentally important problem because the information thus obtained may benefit the understanding of many basic biol. processes and provide useful clues for drug design. In this study, based on the information of chem.-chem. interactions, a novel method was developed that can be used to identify which of the following eleven metabolic pathway classes a query compound may be involved with: (1) Carbohydrate Metabolism, (2) Energy Metabolism, (3) Lipid Metabolism, (4) Nucleotide Metabolism, (5) Amino Acid Metabolism, (6) Metabolism of Other Amino Acids, (7) Glycan Biosynthesis and Metabolism, (8) Metabolism of Cofactors and Vitamins, (9) Metabolism of Terpenoids and Polyketides, (10) Biosynthesis of Other Secondary Metabolites, (11) Xenobiotics Biodegradation and Metabolism It was observed that the overall success rate obtained by the method via the 5-fold cross-validation test on a benchmark dataset consisting of 3,137 compounds was 77.97%, which is much higher than 10.45%, the corresponding success rate obtained by the random guesses. Besides, to deal with the situation that some compounds may be involved with more than one metabolic pathway class, the method presented here is featured by the capacity able to provide a series of potential metabolic pathway classes ranked according to the descending order of their likelihood for each of the query compounds concerned. Furthermore, our method was also applied to predict 5,549 compounds whose metabolic pathway classes are unknown. Interestingly, the results thus obtained are quite consistent with the deductions from the reports by other investigators. It is anticipated that, with the continuous increase of the chem.-chem. interaction data, the current method will be further enhanced in its power and accuracy, so as to become a useful complementary vehicle in annotating uncharacterized compounds for their biol. functions.

Widyastuti, Indah; Ainurofiq, Ahmad; Soewandhi, Sundani Nurono published an article in 2019, the title of the article was Effects of thermal energy, mechanical energy, and solvent on ciprofloxacin hydrochloride monohydrate physicochemical properties.SDS of cas: 86393-32-0 And the article contains the following content:

Ciprofloxacin HCl is available in the form of anhydrate and monohydrate. Water content can affect the hydrolysis, hygroscopicity, bond, and crystal properties of an active substance. This study was aimed to observe the physicochem. phenomena that occur in ciprofloxacin HCl monohydrate because of thermal energy, mech. energy, and solvent. Ciprofloxacin HCl monohydrate from two different producers were given treatments by thermal energy, mech. energy, and solvent. Afterward, the ingredients were characterized using XRD, DSC, and SEM. Other than that, crystal habit, modulus of elasticity, and dissolution were assessed. The results of characterization before and after treatment were compared to observe any changes. Ciprofloxacin HCl monohydrate from two different producers showed similarities in physicochem. properties. Manufacture treatment, which includes thermal energy, mech. energy, and solvent, affected the physicochem. characteristics of ciprofloxacin HCl monohydrate. The effect of thermal energy and solvent can change ciprofloxacin from hydrate to anhydrate, thus changed its dissolution level. Meanwhile, mech. effect by grinding and compression can decrease crystallinity and change the particle size of ciprofloxacin HCl monohydrate, thus change its dissolution level. The results of this study showed that the process of manufacturing can change the physicochem. characteristics of ciprofloxacin HCl monohydrate. The experimental process involved the reaction of 1-Cyclopropyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid hydrochloride hydrate(cas: 86393-32-0).SDS of cas: 86393-32-0

Rispal, P; Grellet, J; Celerier, C; Breilh, D; Dorian, M; Pellegrin, J L; Saux, M C; Leng, B published an article in 1996, the title of the article was Comparative uptake of sparfloxacin and ciprofloxacin into human THP 1 monocytic cells..Related Products of 86393-32-0 And the article contains the following content:

The uptake of sparfloxacin (CAS 11542-93-9) by human monocytes was studied by comparison with ciprofloxacin (CAS 86393-32-0). The human monocytic THP 1 cells were incubated with the antibiotics for 2 h. Entry of antimicrobials into the cells was determined by means of a velocity gradient centrifugation technique and HPLC assay. Antibiotic uptake was expressed as the ratio of the intracellular to the extracellular drug concentration (IC/EC). Quinolones enter readily in monocytic cells but sparfloxacin is taken up more rapidly than ciprofloxacin. At steady-state the IC/EC ratio of sparfloxacin (9.07) is higher than IC/EC of ciprofloxacin (4.29). Characterization of quinolone uptake suggests that these drugs penetrate throughout the THP 1 membrane by passive diffusion. However, the results of the present study indicate that additional mechanisms may contribute to intracellular accumulation of ciprofloxacin and sparfloxacin. Gemfibrozil, an inhibitor of organic anion transport, increases the accumulation of ciprofloxacin but does not modify IC/EC of sparfloxacin. It can be concluded that human monocyte-like cells have functional organic anion transporters and that this way of secretion is quinolone selective.

On November 30, 2021, Sarwar, M. Sohail; Ghaffar, Abdul; Huang, Qingrong published an article.Computed Properties of 86393-32-0 The title of the article was Development and characterization of sodium alginate/poly(sodium 4-styrenesulfonate) composite films for release behavior of ciprofloxacin hydrogen chloride monohydrate. And the article contained the following:

Biopolymers, in particular polysaccharides, have attracted considerable interest in the field of drug delivery due to their biodegradable and biocompatible nature. This study is focused on the preparation and characterization of drug delivery devices based on sodium alginate (SA) composite films with poly(sodium 4-styrenesulfonate) (PSS). The prepared composite films were characterized for the determination of physiochem. properties, mol. interactions, and drug release behavior. The possible intermol. hydrogen bonding between SA and PSS was determined by ATR-FTIR spectroscopy. Surface characterization was done using AFM. Polymeric films consisted of pristine SA and PSS exhibited relatively uniform and flat surfaces. However, the composite films showed phase separation that became more prominent as the concentration of PSS in the composite films was increased up to 40% (weight/weight). The contact angle (CA) values, using deionized water as a function of time (s), were ranging from 74° to 90°, and a decrease in CA (64° to 76°) was recorded for each composite film till 40 s. These CA values revealed that all the composite films were hydrophobic. It was observed that as the concentration of PSS in the films increased, hydrophobicity slightly varied as compared to the blank films of SA and PSS. Maximum CA (89°) was shown by a composite film having SA/PSS (90/10). Ciprofloxacin hydrochloride monohydrate (CPX), a model drug, loaded in a suitable composite film (crosslinked with 0.3 M CaCl2 solution) and drug release was evaluated in pH 1.2 simulated gastric fluid (SGF) and pH 7.4 phosphate buffer saline (PBS) solution In SGF, around 90% of the model drug was released in 110 min that was approx. 77% in the case of PBS. Therefore, it was concluded that a sustained drug release behavior was exhibited in SGF as compared to PBS solution These results suggest that these films are a promising and may potentially be subjected to study further their drug delivery behavior in applications like wound dressing. The experimental process involved the reaction of 1-Cyclopropyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid hydrochloride hydrate(cas: 86393-32-0).Computed Properties of 86393-32-0

Akdag, Yagmur; Sahin, Selma; Nemutlu, Emirhan; Oner, Levent published an article in 2019, the title of the article was Determination of N-acetylcysteine in the presence of ciprofloxacin or levofloxacin in microparticulate dry powder inhalers.Name: 1-Cyclopropyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid hydrochloride hydrate And the article contains the following content:

A fast and easy method was validated for simultaneous determination of ciprofloxacin hydrochloride monohydrate (CP), levofloxacin hemihydrate (LV), and N-acetylcysteine (NAC) in samples. The anal. was performed on a C18 column (250 × 4.6 mm, 5μm) (Inertsil ODS-3V) using an isocratic elution method with a mobile phase composed of 25 mM KH2 PO4 (pH 3.0) and methanol (72:28, volume/volume) at a flow rate of 1 mL/min. UV detection was performed at 214 nm for NAC and 293 nm for CP and LV. The method was validated for linearity, accuracy, precision (repeatability and reproducibility), specificity, sensitivity, and stability. The calibration study using several media demonstrated that the calibration curves were linear for all compounds in all media (R2 >0.9993). The limit of detection was 0.098μg/mL for CP, 0.049μg/mL for LV, and 0.487μg/mL for NAC. The limit of quantification was 0.328μg/mL for CP, 0.165μg/mL for LV, and 1.624μg/mL for NAC. Precision and accuracy values of the method fulfilled the required limits. All these outcomes demonstrate that the validated HPLC method is appropriate for simultaneous anal. of CP, LV, and NAC in samples for content uniformity of dry powder inhaler and permeability studies.

On September 30, 2004, Weyenberg, W.; Vermeire, A.; D’Haese, E.; Vanhaelewyn, G.; Kestelyn, P.; Callens, F.; Nelis, H. J.; Remon, J. P.; Ludwig, A. published an article.Formula: C17H21ClFN3O4 The title of the article was Effect of different sterilisation methods on the properties of bioadhesive powders and ocular minitablets, and clinical evaluation. And the article contained the following:

The purpose of this study was to evaluate the influence of gamma-irradiation and dry heat sterilization on the properties of a bioadhesive powder mixture containing ciprofloxacin and its corresponding ocular minitablets. The mol. weight characteristics of drum dried waxy maize starch (DDWM), employed as major component of the bioadhesive formulation, the decay kinetics of radicals, the rheol. properties of the bioadhesive polymers and the microbial activity of ciprofloxacin were studied. The influence of the different sterilization methods on the characteristics of the ocular minitablets was investigated by measuring the crushing strength, the friability, and the in vitro release of ciprofloxacin from the minitablets. Finally, the clin. value of the selected sterilized minitablets was evaluated in seven healthy volunteers. Both sterilization methods similarly affected the properties of the bioadhesive formulation by inducing stable radicals and decreasing the mol. weight of DDWM, although no changes in the microbiol. activity of ciprofloxacin were measured. An obvious influence of both sterilization methods was observed in the in vitro release study. The crushing strength and friability of the minitablets were not significantly influenced by gamma-irradiation Based on these data, gamma-irradiation was more adequate as sterilization method for the bioadhesive ocular minitablets than dry heat sterilization, because it affected the least the phys. properties of the minitablets. Therefore, the gamma-sterilized minitablets were selected for an in vivo evaluation in seven volunteers. The concentration of ciprofloxacin in the tear film remained above its MIC value for the most common ocular pathogens for at least 8 h. Consequently, the gamma-irradiated minitablets containing ciprofloxacin can be considered as a promising formulation to treat bacterial keratitis and conjunctivitis. The experimental process involved the reaction of 1-Cyclopropyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid hydrochloride hydrate(cas: 86393-32-0).Formula: C17H21ClFN3O4

On December 2, 2004, Faour, Joaquina; Vergez, Juan A. published a patent.Name: 1-Cyclopropyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid hydrochloride hydrate The title of the patent was Breakable, controlled-release tablets comprising a preformed passage. And the patent contained the following:

The invention relates to a simple and improved osmotic device for the controlled release of an active agent from the core into the use environment. According to the invention, the active agent is first released through a preformed passage and, subsequently, through a second passage which is formed in situ. Optionally, the size of one or both of the passages increases during the use of the osmotic device. Moreover, the preformed passage and/or the second passage increases the release speed of the active agent and enables the release of larger particles containing the active agent and/or the release of active agents which are essentially insoluble in the use environment. Owing to the in situ formation of the second opening, the device can release a greater percentage of active agent than that which would be released without said second opening. The experimental process involved the reaction of 1-Cyclopropyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid hydrochloride hydrate(cas: 86393-32-0).Name: 1-Cyclopropyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid hydrochloride hydrate
