On December 31, 2021, Abumiya, Maiko; Takahashi, Naoto; Takahashi, Saori; Yoshioka, Tomoko; Kameoka, Yoshihiro; Miura, Masatomo published an article.Category: piperazines The title of the article was Effects of SLC22A2 808G>T polymorphism and bosutinib concentrations on serum creatinine in patients with chronic myeloid leukemia receiving bosutinib therapy. And the article contained the following:

The purpose of this study was to investigate the effects of SLC22A2 808G>T polymorphism and trough concentrations (C0) of bosutinib on serum creatinine in 28 patients taking bosutinib. At 1, 3, 6, 12, 24, and 36 mo after administration, anal. of bosutinib C0 and creatinine was performed at the same time of day. Significant correlations were observed between bosutinib C0 and the change rate of serum creatinine or the estimated glomerular filtration rate (eGFR; r = 0.328, P < 0.001 and r = - 0.315, P < 0.001, resp.). These correlations were particularly high in patients having the SLC22A2 808G/G genotype (r = 0.345 and r = - 0.329, resp.); however, in patients having the 808T allele, there were no significant differences. In multivariate analyses, the SLC22A2 808G/G genotype, patient age, bosutinib C0 and second-line or later bosutinib were independent factors influencing the change rate of creatinine. Bosutinib elevated serum creatinine through organic cation transporter 2 (OCT2). We observed a 20% increase in serum creatinine with a median bosutinib C0 of 63.4-73.2 ng/mL. Periodic measurement of serum creatinine after bosutinib therapy is necessary to avoid progression to severe renal dysfunction from simple elevation of creatinine mediated by OCT2 following bosutinib treatment. 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).Category: piperazines

On April 30, 2022, Dahlen, Torsten; Edgren, Gustaf; Ljungman, Per; Flygt, Hjalmar; Richter, Johan; Olsson-Stromberg, Ulla; Wadenvik, Hans; Dreimane, Arta; Myhr-Eriksson, Kristina; Zhao, Jingcheng; Sjalander, Anders; Hoglund, Martin; Stenke, Leif published an article.Application of 380843-75-4 The title of the article was Adverse outcomes in chronic myeloid leukemia patients treated with tyrosine kinase inhibitors: Follow-up of patients diagnosed 2002-2017 in a complete coverage and nationwide agnostic register study. And the article contained the following:

Tyrosine kinase inhibitors (TKIs) have profoundly improved the clin. outcome for patients with chronic myeloid leukemia (CML), but their overall survival is still subnormal and the treatment is associated with adverse events. In a large cohort-study, we assessed the morbidity in 1328 Swedish CML chronic phase patients diagnosed 2002-2017 and treated with TKIs, as compared to that in carefully matched control individuals. Several Swedish patient registers with near-complete nationwide coverage were utilized for data acquisition. Median follow-up was 6 (IQR, 3-10) years with a total follow-up of 8510 person-years for the full cohort. Among 670 analyzed disease categories, the patient cohort showed a significantly increased risk in 142 while, strikingly, no category was more common in controls. Increased incidence rate ratios/IRR (95% CI) for more severe events among patients included acute myocardial infarction (AMI) 2.0 (1.5-2.6), heart failure 2.6 (2.2-3.2), pneumonia 2.8 (2.3-3.5), and unspecified sepsis 3.5 (2.6-4.7). When comparing patients on 2nd generation TKIs vs. imatinib in a within-cohort anal., nilotinib generated elevated IRRs for AMI (2.9; 1.5-5.6) and chronic ischemic heart disease (2.2; 1.2-3.9), dasatinib for pleural effusion (11.6; 7.6-17.7) and infectious complications, for example, acute upper respiratory infections (3.0; 1.4-6.0). Our extensive real-world data reveal significant risk increases of severe morbidity in TKI-treated CML patients, as compared to matched controls, particularly for 2nd generation TKIs. Whether this increased morbidity may also translate into increased mortality, thus preventing CML patients to achieve a normalized overall survival, needs to be further explored. 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).Application of 380843-75-4

Chaekal, Ok-kyong; van Besien, Koen published an article in 2020, the title of the article was Allogeneic transplant for CML in chronic phase after failure of imatinib. Not needed or needlessly neglected?.COA of Formula: C26H29Cl2N5O3 And the article contains the following content:

Imatinib first reported in 2001 revolutionized treatment for CML and ushered in the “TKI era’. Second and third generation TKI’s soon followed and presented alternatives for patients failing or unable to tolerate imatinib. They compared them with 1361 patients reported to the Center for International Bone Marrow Transplant Research (CIBMTR) who underwent allogeneic transplantation, also after failing at least one TKI. All patients were diagnosed and treated between 2001 and 2013. About half of the patients had accelerated or blast phase disease. Nilotinib and dasatinib were FDA approved in the second half of 2007, Bosutinib and Ponatinib not until 2012. The most serious toxicities are cardiovascular with an increasing incidence of arterial and venous thrombosis. But numerous other side effects occur. For those who fail imatinib, complete cytogenetic remissions to second or third generation TKI are 50% at best. 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).COA of Formula: C26H29Cl2N5O3

On March 10, 2006, Huang, Jian-Dong; Liu, Feng-Ran; Chen, Yan-Mei; Sun, Jian-Cheng; Jiang, Zhou published an article.Quality Control of 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone The title of the article was Tetra-(acetyl piperazine phenoxy) phthalocyaninato zinc complexes and their proteins conjugates: synthesis, characterisation and photodynamic activities. And the article contained the following:

Two zinc phthalocyanines, tetra-α-[4-(4-acetyl piperazine) phenoxy] phthalocyaninato zinc (C80H72N16O8Zn) and tetra-β-[4-(4-acetyl piperazine) phenoxy] phthalocyaninato zinc (C80H72N16O8Zn), have been synthesized and characterized with 1H NMR, MS, IR and elemental anal. The electronic absorption spectra of two complexes in common organic solvents (N,N-DMF, THF, n-octanol) were typical for nonaggregated phthalocyanines, showing a Q band at 693∼698 nm for 1 and 681 ∼ 682 nm for 2. This indicates that the Q band of zinc phthalocyanine with the substituted groups located in the α position is largely red shifted than that in the β position. The spectral features of complexes 1 and 2 in aqueous media suggest the α-substituted groups are more effective than β-substituted groups to hinder the aggregation of phthalocyanine mol. The interactions between two complexes with serum albumin and transferrin (BSA, HSA and apoTf) were investigated by absorption and fluorescence spectroscopy. The binding constants were found to be (1 ∼ 20) × 105 mol-1·L. By comparison, β-substituted 2 had stronger combining ability with albumin than that of α-substituted 1. The non-covalent conjugates (1-BSA, 2-BSA, 1-HSA, 1-apoTf and 1-FeTf) with the molar ratio of about 1 : 1 have also been prepared The photodynamic activities of two complexes and their bioconjugates against MCF-7 mammary tumor cells were examined The result shows that the photocytotoxicities of conjugates are higher than that of complexes 1 ∼ 2 and follows the order 1-BSA > 1-FeTf > 1-HSA, 1-apoTf > 2-BSA > 1>2. The experimental process involved the reaction of 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone(cas: 67914-60-7).Quality Control of 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone

On July 31, 2020, Hino, Masayuki; Matsumura, Itaru; Fujisawa, Shin; Ishizawa, Kenichi; Ono, Takaaki; Sakaida, Emiko; Sekiguchi, Naohiro; Tanetsugu, Yusuke; Fukuhara, Kei; Ohkura, Masayuki; Koide, Yuichiro; Takahashi, Naoto published an article.Formula: C26H29Cl2N5O3 The title of the article was Phase 2 study of bosutinib in Japanese patients with newly diagnosed chronic phase chronic myeloid leukemia. And the article contained the following:

Abstract: This open-label, single-arm, phase 2 study (ClinicalTrials.gov, NCT03128411) evaluated the efficacy, safety, and pharmacokinetics of bosutinib at a starting dose of 400 mg once daily (QD) in Japanese patients with newly diagnosed chronic phase chronic myeloid leukemia (CP CML). The primary endpoint was major mol. response (MMR) at Month 12 in the modified as-treated population (Philadelphia chromosome-pos. [Ph+] patients with e13a2/e14a2 transcripts). Sixty Japanese patients with CP CML were treated with bosutinib; median age was 55 years (range 20-83), 60.0% were males, and all were Ph+ and had e13a2/e14a2 transcripts. After median follow-up of 16.6 mo (range 11.1-21.9), 41 (68.3%) patients remained on bosutinib. The MMR rate at Month 12 was 55.0% (2-sided 90% confidence interval: 44.4-65.6). There were no on-treatment transformations to accelerated/blast phase, and no patient died on treatment or within 28 days of the last bosutinib dose. The most common treatment-emergent adverse events were diarrhea (86.7%), increased alanine aminotransferase (55.0%), and increased aspartate aminotransferase (46.7%). The primary objective of this phase 2 study was met, and there were no new safety signals for bosutinib. These data suggest bosutinib is an effective first-line treatment option for Japanese patients with newly diagnosed CP CML. 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).Formula: C26H29Cl2N5O3

And the article contained the following:

Bosutinib is approved in the United States, Europe, Japan, and other countries for treatment of newly diagnosed chronic phase (CP) chronic myeloid leukemia (CML), and CML resistant/intolerant to prior therapy. In the phase 3 BFORE trial (Clinicaltrials.gov, NCT02130557), patients were randomized 1:1 to first-line bosutinib or imatinib 400 mg once daily. We examined efficacy, safety, and patient-reported outcomes of bosutinib vs imatinib and pharmacokinetics of bosutinib in the Asian (n = 33 vs 34) and non-Asian (n = 235 vs 234) subpopulations of BFORE followed for at least 24 mo. At the data cutoff date, 72.7 vs 66.7% of Asian and 70.6 vs 66.4% of non-Asian patients remained on treatment. The major mol. response rate at 24 mo favored bosutinib vs imatinib among Asian (63.6 vs 38.2%) and non-Asian (60.9 vs 52.6%) patients, as did the complete cytogenetic response rate by 24 mo (86.7 vs 76.7%, 81.5 vs 76.3%). Treatment-emergent adverse events in both subpopulations were consistent with the primary BFORE results. Trough bosutinib concentration levels tended to be higher in Asian patients. Health-related quality of life was maintained after 12 mo of bosutinib in both subpopulations. These results support bosutinib as a first-line treatment option in Asian patients with CP CML. 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).Category: piperazines

Tyrosine kinase inhibitors (TKIs) are teratogenic. Chronic myeloid leukemia (CML) is increasingly identified in younger patients who wish to conceive, the management of CML during pregnancy is challenging. We reviewed 51 pregnancies involving 37 patients (30 women, 10 with >1 pregnancy and 7 men) who were either diagnosed with CML during pregnancy or receiving TKI at the time of conception. Ten women were involved in >1 pregnancies. Fifteen women were diagnosed with CML during pregnancy: 10 were treated with hydroxyurea (n = 5), interferon-alfa (n = 3), leukapheresis (n = 1), or nilotinib (n = 1). There were 14 (82%) healthy babies born on term including 2 sets of twins, 2 spontaneous miscarriages (12%), and 1 elective abortion (6%). Within 1 mo of delivery or abortion, all women started TKI and achieved MR4.5 (n = 6) and MMR (n = 8) within 3-48 mo. One patient, treated with interferon during pregnancy, died of blast phase within 2 mo. Four of the 14 remaining women later conceived 5 other pregnancies while on TKI (3 unplanned, 2 planned). Twenty-six patients (7 men; 19 women) conceived while on TKI, with a total of 36 pregnancies. Fifteen women had 20 unplanned pregnancies while receiving TKI and discontinued immediately upon recognition of pregnancy. The median time of TKI exposure was 3 wk (range, 2-11). Five pregnancies ended in miscarriages and 3 in elective abortion. All 7 men fathered 7 full-term healthy babies. Of 20 babies born to men and women (including one set of twins), 1 had minor abnormality. Seven women lost their responses during pregnancy but at the end of pregnancy all but 2 resumed TKI and regained responses. Seven women involved in 9 planned pregnancies discontinued TKI prior to conception for a median of 4 mo (range, 1-20); 3 lost responses during pregnancy. Only 5 patients resumed therapy after delivery. Outcomes were 6 full-term healthy babies, one premature, and two miscarriages. Conception among CML patients while on TKI could be uncomplicated. While patients may lose response following treatment interruption, nearly all regain response upon resuming therapy. Therapy during pregnancy is rarely needed. 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).Product Details of 380843-75-4

And the article contained the following:

Bosutinib has been investigated in multiple clin. trials globally, including Japan, for treatment of chronic myeloid leukemia (CML). A pooled anal. of seven Pfizer-sponsored clin. trials evaluated the safety of bosutinib in Japanese (n = 138) vs non-Japanese (n = 1210) patients with CML. First-line bosutinib was administered in 54.3% vs 41.4% of patients, and second-line or later bosutinib in the remainder. Median treatment duration was 1.4 vs 2.3 years, and median relative dose intensity 78.1% vs 90.0%. Any-grade treatment-emergent adverse events (TEAEs) occurred in 100.0% vs 98.9% (grade ≥ 3: 81.9% vs 75.2%). In both groups, the most common TEAEs relevant to bosutinib were gastrointestinal (92.8% vs 84.7%), liver function (72.5% vs 34.8%), rash (63.8% vs 37.4%), and myelosuppression (55.1% vs 50.7%). TEAEs led to dose reduction in 65.2% vs 50.6%, dose interruption in 78.3% vs 68.8%, and permanent treatment discontinuation in 30.4% vs 25.4% of patients. The safety profile of bosutinib in Japanese patients was generally consistent with that in non-Japanese patients, despite a higher incidence of gastrointestinal, liver function, and rash events. TEAEs were largely manageable with dose modifications and supportive care in both groups. These data may help optimize TEAE management and outcomes in Japanese patients receiving bosutinib for CML.
