The first Q-Tube based high-pressure synthesis of anti-cancer active thiazolo[4,5-c]pyridazines via the [4+2] cyclocondensation of 3-oxo-2-arylhydrazonopropanals with 4-thiazolidinones

A novel and efficient protocol for the synthesis of thiazolo[4,5-c]pyridazine derivatives was developed. The approach utilizes a high pressure Q-Tube reactor to promote cyclocondensation reactions between 3-oxo-2-arylhydrazonopropanals and 4-thiazolidinones. The process has a significantly high atom economy and a broad substrate scope, as well as being applicable to gram scale syntheses. The in vitro cytotoxic activities of the synthesized thiazolo[4,5-c]pyridazine derivatives were examined utilizing a MTT colorimetric assay with doxorubicin as a reference anti-cancer drug and three human cancer cell lines including HCT-116 (colon), MCF-7 (breast) and A549 (lung). The results show that thiazolopyridazines 7c, h, k and p have high cytotoxic activity against the MCF-7 cell line with respective IC50 values of 14.34, 10.39, 15.43 and 13.60 mu M. Moreover, the thiazolopyridazine derivative 7s also show promising cytotoxic activity against the HCT-116 cell line with IC50 = 6.90 mu M. Observations made in this effort serve as a basis for further investigations into the design and preparation of new anti-cancer drugs.

A Mountaineering Strategy to Excited States: Highly Accurate Energies and Benchmarks for Medium Sized Molecules

Following our previous work focusing on compounds containing up to 3 non-hydrogen atoms [J. Chem. Theory Comput. 2018, 14, 4360-4379], we present here highly accurate vertical transition energies obtained for 27 molecules encompassing 4, 5, and 6 non-hydrogen atoms: acetone, acrolein, benzene, butadiene, cyanoacetylene, cyanoformaldehyde, cyanogen, cyclopentadiene, cyclopropenone, cyclopropenethione, diacetylene, furan, glyoxal, imidazole, isobutene, methylenecyclopropene, propynal, pyrazine, pyridazine, pyridine, pyrimidine, pyrrole, tetrazine, thioacetone, thiophene, thiopropynal, and triazine. To obtain these energies, we use equation-of-motion/linear-response coupled cluster theory up to the highest technically possible excitation order for these systems (CC3, EOM-CCSDT, and EOM-CCSDTQ) and selected configuration interaction (SCI) calculations (with tens of millions of determinants in the reference space), as well as the multiconfigurational n-electron valence state perturbation theory (NEVPT2) method. All these approaches are applied in combination with diffuse-containing atomic basis sets. For all transitions, we report at least CC3/aug-cc-pVQZ vertical excitation energies as well as CC3/aug-cc-pVTZ oscillator strengths for each dipole-allowed transition. We show that CC3 almost systematically delivers transition energies in agreement with higher-level methods with a typical deviation of +/- 0.04 eV, except for transitions with a dominant double excitation character where the error is much larger. The present contribution gathers a large, diverse, and accurate set of more than 200 highly accurate transition energies for states of various natures (valence, Rydberg, singlet, triplet, n -> pi*, pi -> pi*, …). We use this series of theoretical best estimates to benchmark a series of popular methods for excited state calculations: CIS(D), ADC(2), CC2, STEOM-CCSD, EOM-CCSD, CCSDR(3), CCSDT-3, CC3, and NEVPT2. The results of these benchmarks are compared to the available literature data.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 19430-93-4, you can contact me at any time and look forward to more communication. Computed Properties of C6H3F9.

Development and Characterization of a Fluorescent Probe for GLS1 and the Application for High-Throughput Screening of Allosteric Inhibitors

Glutaminase (GLS1) is a cancer energy metabolism protein which plays a predominant role in cell growth and proliferation. Because of its major involvement in malignant tumor, small-molecule GLS1 inhibitors are urgently needed to assess its therapeutic potential and for probing their underlying biology function. Recent studies showed that targeting the allosteric binding site represented a promising strategy for identifying potent and selective GLS1 inhibitors. Herein, we present the synthesis of two fluorescent probes targeting the allosteric binding site of GLS1 and their usage as mechanistic tools in multiple applicable assay platform. The fluorescence polarization (FP)-based binding assay enables easy, fast, and reliable screen of allosteric inhibitors from our in-house compound library obtained through click chemistry method. The obtained compound C147 (named as CPU-L1) has been proved to be more potent and with greater solubility than the control compound CB839, which could serve as promising leads for further optimization as novel GLS1 inhibitors.

Design, synthesis and evaluation of MCH receptor 1 antagonists – Part II: Optimization of pyridazines toward reduced phospholipidosis and hERG inhibition

Abstract Despite recent success there remains a high therapeutic need for the development of drugs targeting diseases associated with the metabolic syndrome. As part of our search for safe and effective MCH-R1 antagonists for the treatment of obesity, a series of 3,6-disubstituted pyridazines was evaluated. During optimization several issues of the initial lead structures had to be resolved, such as selectivity over related GPCRs, inhibition of the hERG channel as well as the potential to induce phospholipidosis. Utilizing property-based design, we could demonstrate that all parameters can significantly be improved by consequently increasing the polarity of the compounds. By this strategy, we succeeded in identifying potent and orally available MCH-R1 antagonists with good selectivity over M1 and 5-HT2A and an improved safety profile with respect to hERG inhibition and phospholipidosis.
