We report a new application of N-amino-7-azaindole as a new bidentate-directing group for [Ru(p-cymene)Cl-2](2)-catalyzed C(sp(2))-H alkenylation/annulation of N-(1H-pyrrolo[2,3-b]pyridin-1-yl)benzamides with internal alkynes to afford N-isoquinolono-7-azaindole via the formation of C-C and C-N bonds. The reaction shows a wide range of substrate scope with different symmetrical and unsymmetrical alkynes, affording the desired product in good to excellent yields. In the case of unsymmetrical alkynes, a highly regioselective product was obtained, which was confirmed by single-crystal X-ray crystallography. A new ruthenium-4-methyl-N-(1H-pyrrolo[2,3-b]pyridin-1-yl)benzamide complex was isolated, and its structure was confirmed by single-crystal X-ray crystallography.

The FGFR family is characterized by four receptors (FGFR 1-4), binding to 18 ligands called fibroblast growth factors (FGFs). Aberrant activation of FGFs and their FGFRs has been implicated in a broad spectrum of human tumors. We employed the scaffolds hybridization approach, scaffold-hopping concept to synthesize a series of novel pyrazole-benzimidazole derivatives 56 (a-x). Compound 56q (CPL304110) was identified as a selective and potent pan-FGFR inhibitor for FGFR1, -2, -3 with IC(50)s of 0.75 nM, 0.50 nM, 3.05 nM respectively, whereas IC50 of 87.90 nM for FGFR4. Due to its favorable pharmacokinetic profile, low toxicity and potent anti-tumor activity in vivo, compound 56q is currently under evaluation in phase I clinical trial for the treatment of bladder, gastric and squamous cell lung cancers (01FGFR2018; NCT04149691).

Thirty-four seco-3’R,4’R-disubstituted-2′,2′-dimethyldihydropyrano[2,3-f]chromone (seco-DSP) derivatives were designed, synthesized and evaluated for chemo-reversal activity when combined with paclitaxel or vincristine in P-gp overexpressing A2780/T and KB-VIN drug-resistant cancer cell lines. Most of the compounds displayed moderate to significant MDR reversal activities. Compound 7e showed the most potent chemo-sensitization activity with more than 1471 reversal ratio at a concentration of 10 mu M, which was higher than verapamil (VRP) (212-fold). Unexpectedly the newly synthesized compounds did not show chemosensitization activities in a non-P-gp overexpressing cisplatin resistant human ovarian cancer cell line (A2780/CDDP), implying that the MDR reversal effects might be associated with P-gp overexpression. Moreover, the compounds did not exhibit significant anti-proliferative activities against non-tumorigenic cell lines (HUVEC, HOSEC and T29) compared to VRP at the tested concentration and might be safer than VRP. In preliminary pharmacological mechanism studies, the compounds increased accumulation of DOX and promoted P-gp ATPase activity in A2780/T cell lines. Western blot analysis indicated they did not affect the expression level of P-gp in the tested MDR cell lines. Thus, further studies on these seco-DSP derivatives are merited with the goal of developing a desirable chemosensitizer drug candidate. (C) 2020 Elsevier Masson SAS. All rights reserved.

Work previously published by our group described novel methodology for the synthesis of xanthones and related products from phenolic benzophenones in a reaction mediated by ceric ammonium sulfate (CAS). In this paper we further explore this novel reaction by subjecting an additional set of phenolic benzophenones to CAS to afford a range of compounds, including xanthones, 9H-xanthen-2,9(4aH)-diones, 3H-spiro[benzofuran-2,1′-cyclohexa[2,5]-diene]-3,4′-diones, and biaryl compounds. A comparison of these reactions with the more commonly used oxidant ceric ammonium nitrate (CAN) was also conducted. Based on these results, greater insight into the reaction mechanism has been gained. In addition, the conversion of the synthesized xanthen-2,9(4aH)-diones to xanthones by treatment with sodium dithionite is described.

SCM-198 (Leonurine) has attracted great attention due to its cardioprotective effects in myocardial infarction (MI). However, no systematic modifications and structure-activity relationship (SAR) studies could be traced so far. In this study, 35 analogs of SCM-198 were designed, synthesized and their cardioprotective effects were evaluated. The cell viability assay on cardiomyocyte cell line H9c2 challenged with H2O2 showed that several analogs exhibited more potent cytoprotective effects than SCM-198 at 1 mu M and 10 mu M concentrations. LDH release level in cells treated with 1 mu M 14o was comparable with cells treated with 10 mu M SCM-198. Results of Bcl-2 expression and caspase-3 activation accordingly indicated higher protective activity of 14o than SCM-198. Moreover, in a mouse model of MI, the mice pretreated with 14o had much lower infarct size compared with that of SCM-198. The mechanism study suggested that 14o improved cardiac morphology and reduced apoptosis of cardiomyocytes in the border zone of infarction, as proved by H&E and TUNEL staining.

The reaction of TMS-ethers of 2,4-diaryl-1,1,1-trifluorobut-3-en-2-ols with arenes in TfOH at room temperature for 5 min results in the formation of trans-/cis-1,3-diaryl-1-trifluoromethyl indanes in good yields (up to 99%). The predominant or exclusive formation of indanes with a trans-configuration of 1,3-diaryl groups has been observed. The reaction proceeds through an intermediate formation of the corresponding mesomeric CF3-allyl cations. A plausible reaction mechanism is discussed.

Substituted 1,2,4-triazole nucleus is common in several drugs used in a variety of clinical conditions including infections, hypoglycemia, hypertension and cancer. In this study, we synthesized 1,2,4-triazole and its 16 hydrazone derivatives (B1-B16), characterized them by IR, NMR and Mass spectroscopy, and evaluated their radical scavenging and anti-inflammatory activities in vitro and in vivo. Out of 16 derivatives, five (B1, B5, B6, B9, and B13) demonstrated a significant radical scavenging and anti-inflammatory activity in vitro. B6, which possessed two electron-donating hydroxyl groups, was most active among all. Molecular docking and MD simulation of the complex of B6 with prostaglandin-endoperoxide synthase (PTGS) or cyclooxygenase (COX) showed that B6 occupied celecoxib binding site in COX with high affinity (the binding free energy of the complex with COX-1 was -10.5, and -11.2 kcal/mol with COX-2). Maximum anti-inflammatory activity was also shown by the B6 derivative in vivo, in the rat model of carrageenan-induced inflammation. B6, along with four other derivatives (B1, B5, B9 and B13) exhibited 80-90% free radical scavenging activity. The IC50 values of these compounds were >= 40 mu M. Griess nitrite and dichloro-dihydro-fluorescein-diacetate assays suggested a significant inhibition of nitric oxide and reactive oxygen species, especially by B6 and B9. Taken together, out of 16 derivatives, B6 is reported to have highest anti-inflammatory and antioxidant activity at a low dose level, which may be attributed to its two electron-donating hydroxyls. B6 is proposed to be an important scaffold for the synthesis of new drugs against PTGS for use in a myriad of inflammatory and infectious diseases. Communicated by Ramaswamy H. Sarma

A one-pot protocol has been developed for the synthesis of quinazolinones from amide-oxazolines with TsClviaa cyclic 1,3-azaoxonium intermediate and 6 pi electron cyclization in the presence of a Lewis acid and base. The process is operationally simple and has a broad substrate scope. This method provides a unique strategy for the construction of quinazolinones.
