Protein kinases control diversity of biochemical processes in human organism. Checkpoint 1 kinase (Chk1) is an important element of the checkpoint signalling pathways and is responsible for DNA damage repair. Hence, this kinase plays an essential role in cancer cells survival and has become an important target for anticancer agents. Our previous investigations showed that some arylsulphonyl indazole derivatives displayed anticancer effect in vitro. In the present study, in order to verify possibility of interactions of pyrazole and indazole derivatives with Chk1, we focused on the docking of selected tosyl derivatives of indazole and condensed pyrazole 1-7 to the Chk1 pocket, analysis of interactions involving optimized ligand-protein system using DFT formalism, and estimation of the interaction enthalpy of the ligand-protein complex by applying the PM7 method. The estimation of binding affinity seems to indicate that the indazole 5-substituted with 3,5-dimethylpyrazole 4 and condensed pyrazoloquinoline derivative 7 fit the best to the Chk1-binding pocket. The values of the energy of interaction, i.e. the enthalpy change (Delta H-int), were between – 85.06 and – 124.04 kcal mol(-1) for the optimized ligand-Chk1 complexes. The relaxation of the ligands within the complexes azole-protein as well as the distribution of hydrogen contacts between the ligands and kinase pocket amino acids was also analysed using molecular dynamics as a supporting method.

A new series of 2,4-dimethyl-1H-pyrrole-3-carboxamide derivatives bearing benzimidazole moiety was synthesized through a molecular hybridization approach and evaluated for in vitro anticancer activity by NCI-60 on leukemia, melanoma, lung, colon, CNS, ovarian, renal, prostate and breast cancer cell lines at a single dose (10 mu M). Among all the synthesized conjugates, some derivatives showed more or less good activity even at such a small dose, while, compound 5-(1H-benzo[d]imidazol-2-yl) N (1-cyclohexylethyl)-2,4-dimethyl-1H-pyrrole-3-carboxamide (80 displayed significant antiproliferative activity specifically against MDA-MB human cancer cell lines. Compound 8f showed promising activity against MDA-MB-435 cell line of melanoma (Growth inhibition: 62.46%) and MDA-MB-468 cell line of breast (Growth inhibition: 40.24%). Computational ADME study qualified its significant physicochemical, pharmacokinetic and drug-likeness properties with good predicted oral bioavailability. Thus this new hybrid molecules would be useful for further anticancer drug development.

Purpose: Regorafenib is an oral multikinase inhibitor approved for the therapy of previously treated metastatic colorectal carcinoma (mCRC). The aim of the present study was to analyze the outcomes of treatment with regorafenib in real-world clinical practice based on data from a national registry. Methods: The CORECT registry, the Czech non-interventional database of patients with mCRC treated with targeted agents, searched for patients with metastatic CRC treated with regorafenib. In total, 555 evaluable patients were identified. Results: The median age at diagnosis was 61.7 years. All patients had disease progression on or after previous systemic treatment. Most patients were treated with an initial dose of 160 mg daily (n = 463; 83.6%). The median duration of treatment was 2.7 months (range 0.023.4 months). By the data cut-off date, 472 patients (85%) had completed treatment with regorafenib and were evaluable for treatment response evaluation. Partial response was reported in 13 patients (2.8%) and disease stabilization in 130 patients (27.5%). Median progression-free survival (PFS) and overall survival (OS) were 3.5 months (95% confidence interval [CI] 3.2-3.7 months) and 9.3 months (95% CI 8.3-10.3 months), respectively. The 6-month OS rate was 67.7% (95% CI 63.4-72.1%). Multivariable analysis showed that female gender, longer interval from diagnosis of metastatic disease, MO stage at diagnosis, and Eastern Cooperative Oncology Group performance status (ECOG PS) 0 were associated with longer PFS, while higher body-mass index (BMI), longer interval from diagnosis of metastatic disease, and ECOG PS of 0 were associated with longer OS. Conclusion: OS of patients treated with regorafenib in the real-world clinical practice in this cohort exceeded that reported in randomized trials. Regorafenib is a safe and active treatment option for a subgroup of patients with mCRC who are progressing after other systemic therapies and maintain good performance status.

COA of Formula: C5H8N2. I found the field of Chemistry very interesting. Saw the article Syntheses, characterization and DFT studies of two new homo-dinuclear zinc(II) complexes based on pyrazole and 3,5-dimethylpyrazole ligands published in 2020.0, Reprint Addresses Ngoune, J (corresponding author), Univ Dschang, Dept Chem, Dschang, Cameroon.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole.

Two new homo-dinuclear zinc(II) complexes, bis(mu-pyrazolato-) bis[(formato)(pyrazole)zinc(II)], [{Zn(OCHO)(pzH)}(2)(mu-N2H3C3)(2)] (1) and bis(mu-3,5-dimethylpyrazolato)bis[(formato)(-3,5-dimethylpyrazole) zinc(II)], [{Zn(dmpzH)(OCHO)}(2)(m-N2H7C5)(2)] (2), were synthesized through the reactions of zinc(II) formate dihydrate, Zn(OCHO)(2)center dot 2H(2)O with pyrazole (pzH = C3H4N2) and 3,5-dimethyl-pyrazole (dmpzH = C5H8N2), respectively, in toluene at room temperature. These dinuclear complexes have been characterized using different analytical techniques; elemental and thermogravimetric analyses, IR and H-1-NMR spectroscopies, single-crystal X-ray diffraction and DFT studies. Compound 1 crystallized in the P (1) over bar space group of the triclinic crystal system with unit cell parameters a = 8.205(3) angstrom, b = 8.864(5) angstrom, c = 14.486(7) angstrom, alpha = 104.929(14)degrees, beta = 91.214(11)degrees and gamma = 106.921(8)degrees. Compound 2 crystallized in the P2(1)/c space group of the monoclinic crystal system with cell parameters a = 8.400(3) angstrom, b = 11.020(4) angstrom, c = 14.930(5) angstrom, alpha = gamma = 90 degrees and beta = 106.3(10)degrees. Pseudo-tetrahedral coordination geometries were observed around the zinc(II) centers in both complexes, constructed by one oxygen atom from a formate anion and three nitrogen atoms from one pzH and two pyrazolato in 1 or one dmpzH and two 3,5-dimethylpyrazolato in 2. The bulk of these materials are consolidated by weak and strong N-H center dot center dot center dot O, C-H center dot center dot center dot O, C-N center dot center dot center dot O and C-H center dot center dot center dot pi, N-H center dot center dot center dot pi and C-O center dot center dot center dot O intra/intermolecular interactions resulting to zigzag networks containing empty voids. DFT studies on both compounds revealed their optimized structures, frontier molecular orbitals, theoretical IR frequencies and the global reactivity descriptors. [GRAPHICS]

A new family of pyridyl-based NNN pincer ligands bearing a remote pendent OH group were developed. Considerable acceleration effects on the activity of Ru-catalyzed transfer hydrogenation of ketones were imparted by the pendent OH group, and importantly, introducing a CH2OH group to the 4′-position of the pyrazolyl moiety is an appropriate choice. The results present a general strategy for exploring bifunctional ligands to construct effective catalysts.

The changes in spectra and intensities of the streamwise component of turbulent velocity are calculated in the inflow of a turbine rotor. The flow is initially calculated in the limit when the turbulence is of small scale compared with the rotor diameter. Rapid distortion theory (RDT), Batchelor & Proudman (Q. J. Mech. Appl. Maths, vol. 7 (1), 1954, pp. 83-103) (BP), for small-scale turbulence is combined with the effect of the fluctuating potential flow field on the turbulence caused by the direct interaction of the incident turbulence with the rotor as a sheet of resistance. A second computation is then carried out for turbulence of larger length scale. The results of the calculations are compared with velocity measurements in the inflow of both a commercial wind turbine and a tidal turbine rotor.

A new convenient and versatile halogenating system (R(4)NHal/NOHSO4), giving straightforward and general access to halogenated 3,5-diaryl- and alkylarylisoxazoles, pyrazoles and electron-rich benzenes from the corresponding scaffolds, is suggested. The method provides excellent regioselectivity, scalability to the gram scale, and a broad scope for both aromatics and halogens. A three-step, one-pot reaction protocol was developed, and a series of 3,5-diaryl-4-haloisoxazoles has been efficiently synthesized from 1,2-diarylcyclopropanes under suggested nitrosating-halogenating conditions.
