Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine, is researched, Molecular C36H30NO2P, CAS is 415918-91-1, about Enantioselective and diastereodivergent access to α-substituted α-amino acids via dual iridium copper catalysis.Name: (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine.

The work reported within this paper describes an example of the application of bimetallic catalysts system in allylic substitution reactions. The development of new nucleophiles and the control of enantio- and diastereoselectivity are the main research topics in this area. An improvement in the reactivity and diastereoselectivity has been realized for the dual Ir/Cu catalyzed allylic alkylation of inactive prochiral nucleophiles, under mild reaction conditions. Furthermore, the choice of the metallacyclic iridium complex and chiral Cu-Phox complex combination allows for access to all four stereoisomers from the same starting materials with excellent enantioselectivity and diastereoselectivity (up to >99% ee and >20:1 dr). Significantly, this method provides a stereodivergent access to 2-amino-3-methylpent-4-acid ester, an important fragment for the synthesis of Halipeptin A.

CeO2 and NiO buffers for YBCO coated conductors were deposited on biaxially textured Ni substrates by a metalorganic CVD method. The degree of texture and surface roughness of the oxide films were analyzed by x-ray pole figure, at. force microscope (AFM) and SEM. The texture of deposited CeO2 films was a function of deposition temperature and O partial pressure (PO2). The (2 0 0) texture of CeO2 was fully developed at T = 500-520° and PO2 = 3.33 torr. The growth rate of the CeO2 films was 200 nm/min at T = 520° and PO2 = 2.30 torr, which is much faster than those prepared by other phys. deposition methods. The (2 0 0) texture of NiO was formed at T = 450° and PO2 = 1.67 torr. The full width half maximum of the both films was in the range of 8-10°. The AFM surface roughness of the films was between 3.0-10 nm, depending on the deposition temperature

Highly regio- and enantioselective allylation of aromatic amines is observed when a cyclometalated Ir-phosphoramidite complex is generated in situ. The active catalyst can be formed from [{Ir(cod)Cl}2] and ligand L with a volatile alkylamine prior to addition of the reagents or upon use of a tertiary amine additive. E.g., a cyclometalated Ir-phosphoramidite complex catalyzed the allylation of PhNH2 by carbonate (E)-PhCH:CHCH2OC(O)OMe to give 80% (+)-PhCH(NHPh)CH:CH2.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds.

Name: cis-Diammine(1,1-cyclobutanedicarboxylato)platinum(II). The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: cis-Diammine(1,1-cyclobutanedicarboxylato)platinum(II), is researched, Molecular C6H12N2O4Pt, CAS is 41575-94-4, about Impact of homologous recombination status and responses with veliparib combined with first-line chemotherapy in ovarian cancer in the Phase 3 VELIA/GOG-3005 study.. Author is Swisher, Elizabeth M; Aghajanian, Carol; O’Malley, David M; Fleming, Gini F; Kaufmann, Scott H; Levine, Douglas A; Birrer, Michael J; Moore, Kathleen N; Spirtos, Nick M; Shahin, Mark S; Reid, Thomas J; Friedlander, Michael; Steffensen, Karina Dahl; Okamoto, Aikou; Sehgal, Vasudha; Ansell, Peter J; Dinh, Minh H; Bookman, Michael A; Coleman, Robert L.

OBJECTIVE: In the Phase 3 VELIA trial (NCT02470585), PARP inhibitor (PARPi) veliparib was combined with first-line chemotherapy and continued as maintenance for patients with ovarian carcinoma enrolled regardless of chemotherapy response or biomarker status. Here, we report exploratory analyses of the impact of homologous recombination deficient (HRD) or proficient (HRP) status on progression-free survival (PFS) and objective response rates during chemotherapy. METHODS: Women with Stage III-IV ovarian carcinoma were randomized to veliparib-throughout, veliparib-combination-only, or placebo. Stratification factors included timing of surgery and germline BRCA mutation status. HRD status was dichotomized at genomic instability score 33. During combination therapy, CA-125 levels were measured at baseline and each cycle; radiographic responses were assessed every 9 weeks. RESULTS: Of 1140 patients randomized, 742 had BRCA wild type (BRCAwt) tumors (HRP, n = 373; HRD/BRCAwt, n = 329). PFS hazard ratios between veliparib-throughout versus control were similar in both BRCAwt populations (HRD/BRCAwt: 22.9 vs 19.8 months; hazard ratio 0.76; 95% confidence interval [CI] 0.53-1.09; HRP: 15.0 vs 11.5 months; hazard ratio 0.765; 95% CI 0.56-1.04). By Cycle 3, the proportion with ≥90% CA-125 reduction from baseline was higher in those receiving veliparib (pooled arms) versus control (34% vs 23%; P = 0.0004); particularly in BRCAwt and HRP subgroups. Complete response rates among patients with measurable disease after surgery were 24% with veliparib (pooled arms) and 18% with control. CONCLUSIONS: These results potentially broaden opportunities for PARPi utilization among patients who would not qualify for frontline PARPi maintenance based on other trials.

Abstract: Background: Proton pump inhibitors (PPIs) are commonly used concomitant to cancer treatment and they induce gut microbiota changes. It is increasingly apparent that gut dysbiosis can reduce the effectiveness of immune checkpoint inhibitors (ICI). However, little is known about PPI effects on outcomes with ICIs, particularly in combination, ICI approaches. Methods: Post hoc, Cox proportional hazard anal. of phase III trial, IMpower150 was conducted to assess the association between PPI use and overall survival (OS) and progression-free survival (PFS) in chemotherapy-naive, metastatic non-squamous non-small cell lung cancer participants randomised atezolizumab plus carboplatin plus paclitaxel (ACP), bevacizumab plus carboplatin plus paclitaxel (BCP), or atezolizumab plus BCP (ABCP). PPI use was defined as any PPI administration between 30 days prior and 30 days after treatment initiation. Results: Of 1202 participants, 441 (37%) received a PPI. PPI use was independently associated with worse OS (n = 748; hazard ratio (HR) [95% confidence interval (CI)] = 1.53 [1.21-1.95], P < 0.001) and PFS (1.34 [1.12-1.61], P = 0.002) in the pooled atezolizumab arms (ACP plus ABCP). This association was not apparent for BCP (n = 368; OS 1.01 [0.73-1.39], P = 0.969; PFS 0.97 [0.76-1.25], P = 0.827). The observed OS treatment effect (HR 95% CI) of the atezolizumab (ACP plus ABCP) arms vs BCP was 1.03 (0.77-1.36) for PPI users compared to 0.68 (0.54-0.86) for non-users (P [interaction] = 0.028). A similar association was noted for ABCP vs BCP (PPI users 0.96 [0.68-1.35]; PPI non-users 0.66 [0.50-0.87]; P [interaction] = 0.095). Conclusions: PPI use was a neg. prognostic marker in patients treated with ACP or ABCP, but not BCP. The anal. suggests that PPIs neg. influence the magnitude of ICI efficacy.
