On August 31, 2002, Wang, Jingkang; Liu, Yong; Yin, Qiuxiang published an article.Formula: C17H21ClFN3O4 The title of the article was Studies on the mechanism of primary nucleation of ciprofloxacin hydrochloride monohydrate. And the article contained the following:

A general expression for the relation between induction period and supersaturation was developed based on polynuclear approach. Different mechanism of primary nucleation in solution can be illustrated by the expression. The results of induction period determined by laser scattering method shows that the crystallization of ciprofloxacin hydrochloride monohydrate in water/ethanol or aqueous solution is by the mechanism of primary nucleation followed by one-dimensional diffusion growth, and then one-dimensional continuous or “birth and spread” growth on crystal face. The growth mechanism on the crystal face is affected by temperature and solvent. 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

Metabolic syndrome is a widely prevalent multifactorial disorder associated with an increased risk of cardiovascular disease and type 2 diabetes mellitus. High plasma levels of insulin and glucose due to insulin resistance are a major component of the metabolic disorder. Thiazolidinediones (TZDs) are potent PPARγ ligands and used as insulin sensitizers in the treatment of type 2 diabetes mellitus. They are potent insulin-sensitizing agents but due to adverse effects like hepatotoxicity, a safer alternative of TZDs is highly demanded. The synthesis of N-(6-(4-(piperazin-1-yl)phenoxy)pyridin-3-yl)benzenesulfonamide derivatives I (R = 2,4-Cl2C6H3, 2,5-(OCH3)2C6H3, 2-thienyl, etc.) an alternate remedy for insulin resistance is reported.

On December 9, 2021, Perfettini, Jean-Luc; Lecuyer, Deborah; Tannous, Desiree; Allouch, Awatef; Delelis, Olivier; Subra, Frederic published a patent.Quality Control of N-((4-(4-Phenylpiperazin-1-yl)tetrahydro-2H-pyran-4-yl)methyl)-2-(phenylthio)nicotinamide The title of the patent was Modulators of purinergic receptors and related immune checkpoint for treating acute respiratory distress syndrome. And the patent contained the following:

The inventors herein show that purinergic receptors regulate the conversion of macrophage pro-inflammatory reprogramming into anti-inflammatory phenotype in patients suffering from COVID-19 disease. Moreover, they show that P2Y receptor agonists repress NLRP3 inflammasome-dependent IL-1b secretion, but also impair the replication and the cytopathogenic effects of SARS-CoV-2. These results therefore suggest that some purinergic receptors agonists can treat acute lung injury and respiratory disease that are associated with SARS-CoV-2 infection. In addition, their results show that antagonists of the purinergic receptors P2X impair the replication of said virus. The present invention therefore proposes to use purinergic receptors modulators and NLR3-P2Y2R immune checkpoint modulators to treat patients suffering from a virus-induced acute respiratory distress syndrome. The experimental process involved the reaction of N-((4-(4-Phenylpiperazin-1-yl)tetrahydro-2H-pyran-4-yl)methyl)-2-(phenylthio)nicotinamide(cas: 1428327-31-4).Quality Control of N-((4-(4-Phenylpiperazin-1-yl)tetrahydro-2H-pyran-4-yl)methyl)-2-(phenylthio)nicotinamide

And the article contained the following:

A series of 3-carbamate and 29-ester celastrol derivatives I (R1 = H, R2 = H, Me, Et, CHMe2, CH2CH:CH2, CH2Ph, 3-ClC6H4CH2, etc.; R1 = CONMePh, piperidinocarbonyl, morpholinocarbonyl, etc.) were designed and synthesized. These analogs were evaluated for their cytotoxic activities against several cancer cell lines. Cytotoxicity data revealed that the properties of substituents and substitution position had important influence on cytotoxic activity. Modification of C-3 hydroxyl with size-limited groups did not reduce the activity obviously. The introduction of polarity group like piperazine could improve the solubility Compound I (R1 = 4-piperazinocarbonyl, R2 = CH2Ph) (II) was chosen to further evaluate anti-tumor efficacy in vivo. It showed higher inhibition rate and better safety than celastrol during in vivo experiment by intragastric administration. The preliminary antitumor studies of compound II in vivo showed that it might be promising for the development of new antitumor agents. The experimental process involved the reaction of 4-Ethyl-piperazine-1-carbonyl chloride(cas: 53788-12-8).Recommanded Product: 4-Ethyl-piperazine-1-carbonyl chloride

On August 31, 2021, Lakkireddy, Samyuktha; Jayaraman, Archana; Aula, Sangeetha; Kapley, Atya; Kutala, Vijay Kumar; Jamil, Kaiser published an article.Reference of 4-((2,4-Dichloro-5-methoxyphenyl)amino)-6-methoxy-7-(3-(4-methylpiperazin-1-yl)propoxy)quinoline-3-carbonitrile The title of the article was In Silico Docking Studies of Vascular Endothelial Growth Factor-A (VEGFA): Possible Implications in Chronic Myeloid Leukemia (CML) Therapy. And the article contained the following:

Background: Dysregulated angiogenesis resulting in neovascularization is a critical event in the expansion and progression of Chronic Myeloid Leukemia (CML), hematopoietic cancer. Vascular Endothelial Growth Factor- A (VEGFA), an important angiogenesis mediator, has been a target for treating cancer. Although several anti-VEGFA drugs are available, they are associated with adverse side effects, promoting the need to identify better drugs that may be less toxic. Objective: Our aim was to investigate whether Tyrosine Kinase Inhibitors (TKIs) could be repurposed for use as VEGFA inhibitors via in silico docking software. We also investigated the potential of phytochems. as VEGFA inhibitors. Methods: We performed mol. docking using Schrodinger Maestro software suite 2014-3 to determine the most potent phytochem. and TKI VEGFA antagonists. Results: Among the TKIs investigated, Bosutinib had the best binding affinity and may be the most potent TKI against VEGFA. The order of binding affinities for the top ten docked ligands was: Ginsenoside Rg3> Bosutinib> Vitamin D> Paclitaxel> Dasatinib> Saponins> Ponatinib> Squalamine> Imatinib> Nilotinib. We found that Ginsenoside Rg3 had the highest binding affinity (MMGBSA score= -99.4 kcal/mol, glide Gscore = -9.16 kcal/mol) to VEGFA. Conclusion: Our study has shown for the first time the binding poses of these TKIs and phytochems. to VEGFA, using computational methods. We propose that the use of the top scoring ligands, in isolation or a combination of phytochems. plus TKI, could serve as potent angiogenesis inhibitors via their binding to and inhibiting VEGFA expression to prevent CML progression. We have also profiled the ligand binding residues, which may be explored in designing pharmacophores. The experimental process involved the reaction of 4-((2,4-Dichloro-5-methoxyphenyl)amino)-6-methoxy-7-(3-(4-methylpiperazin-1-yl)propoxy)quinoline-3-carbonitrile(cas: 380843-75-4).Reference of 4-((2,4-Dichloro-5-methoxyphenyl)amino)-6-methoxy-7-(3-(4-methylpiperazin-1-yl)propoxy)quinoline-3-carbonitrile

And the article contained the following:

Patients with chronic myeloid leukemia in chronic phase (CML-CP) resistant/intolerant to ≥2 tyrosine kinase inhibitors (TKIs) are at high risk of experiencing poor outcomes because of disease biol. and inadequate efficacy and/or safety of current therapies. Asciminib, a first-in-class BCR-ABL1 inhibitor Specifically Targeting the ABL Myristoyl Pocket (STAMP), has the potential to overcome resistance/intolerance to approved TKIs. In this phase 3, open-label study, patients with CML-CP previously treated with ≥2 TKIs were randomized (2:1) to receive asciminib 40 mg twice daily vs bosutinib 500 mg once daily. Randomization was stratified by major cytogenetic response (MCyR) status at baseline. The primary objective was to compare the major mol. response (MMR) rate at week 24 for asciminib vs bosutinib. A total of 233 patients were randomized to asciminib (n = 157) or bosutinib (n = 76). Median follow-up was 14.9 mo. The MMR rate at week 24 was 25.5% with asciminib and 13.2% with bosutinib. The difference in MMR rate between treatment arms, after adjusting for MCyR at baseline, was 12.2% (95% confidence interval, 2.19-22.30; 2-sided P = .029). Fewer grade ≥3 adverse events (50.6% vs 60.5%) and adverse events leading to treatment discontinuation (5.8% vs 21.1%) occurred with asciminib than with bosutinib. The study showed a superior efficacy of asciminib compared with that of bosutinib, together with a favorable safety profile. These results support the use of asciminib as a new therapy in patients with CML-CP who are resistant/intolerant to ≥2 prior TKIs. This trial was registered at www.clinicaltrials.gov as #NCT03106779. The experimental process involved the reaction of 4-((2,4-Dichloro-5-methoxyphenyl)amino)-6-methoxy-7-(3-(4-methylpiperazin-1-yl)propoxy)quinoline-3-carbonitrile(cas: 380843-75-4).SDS of cas: 380843-75-4

Treatment of advanced-phase chronic myeloid leukemia (CML) remains unsatisfactory. Single-agent tyrosine kinase inhibitors have modest and short-lived activity in this setting. We conducted a phase I/II study to determine safety and efficacy of the combination of dasatinib and decitabine in patients with advanced CML. Two different dose schedules were investigated with a starting decitabine dose of either 10 mg/m2 or 20 mg/m2 daily for 10 days plus dasatinib 100 mg daily. The target dose level was decitabine 10 mg/m2 or 20 mg/m2 daily for 10 days plus dasatinib 140 mg daily. Thirty patients were enrolled, including seven with accelerated-phase CML, 19 with blast-phase CML, and four with Philadelphia-chromosome pos. acute myeloid leukemia. No dose-limiting toxicity was observed at the starting dose level with either schedule. Grade ≥3 treatment emergent hematol. adverse events were reported in 28 patients. Thirteen patients (48%) achieved a major hematol. response and six (22%) achieved a minor hematol. response, with 44% of these patients achieving a major cytogenetic response and 33% achieving a major mol. response. Median overall survival (OS) was 13.8 mo, with significantly higher OS among patients who achieved a hematol. response compared to non-responders (not reached vs 4.65 mo; P < .001). Decitabine plus dasatinib is a safe and active regimen in advanced CML. Further studies using this combination are warranted.
