Alkylation of sulfamic esters by 4-fluorobenzyl bromide

The action of 4-fluorobenzyl bromide on sulfamic esters (R-O-SO 2-NH2) in liquid-liquid phase transfer conditions allows, depending on the nature of R, the preparation of the N-dialkyled products or the corresponding ethers by scissi

Structure based design, synthesis, and biological evaluation of imidazole derivatives targeting dihydropteroate synthase enzyme

In this study, we have designed and synthesized 2-((5-acetyl-1-(phenyl)-4-methyl-1H-imidazol-2-yl)thio)-N-(4-((benzyl)oxy)phenyl) acetamide derivatives. Antimicrobial activities of all the imidazole derivatives have been examined against Gram-positive and Gram-negative bacteria and results showed that the conjugates have appreciable antibacterial activity. Besides, several analogous were evaluated for their in vitro antiresistant bacterial strains such as Extended-spectrum beta-lactamases (ESBL), Vancomycin-resistant Enterococcus (VRE), and Methicillin-resistant Staphylococcus aureus (MRSA). The SAR revealed that the 12l compound resulted in potency against all bacterial strains as well as ESBL, VRE, and MRSA strains. Lipinski's rule of five, and ADME studies were preformed for all the synthesized compounds with Staphylococcus aureus dihydropteroate synthase (saDHPS) protein (PDB ID: 6CLV) and were found standard drug-likeness properties of conjugates. Moreover, the binding mode of the ligands with the protein study has been examined by molecular docking and results are quite promising. Besides, all the analogous were tested for their in vitro antituberculosis, antimalarial, and antioxidant activity.

Synthesis and evaluation of a large library of nitroxoline derivatives as pancreatic cancer antiproliferative agents

Pancreatic cancer (PC) is one of the deadliest carcinomas and in most cases, which are diagnosed with locally advanced or metastatic disease, current therapeutic options are highly unsatisfactory. Based on the anti-proliferative effects shown by nitroxoline, an old urinary antibacterial agent, we explored a large library of newly synthesised derivatives to unravel the importance of the OH moiety and pyridine ring of the parent compound. The new derivatives showed a valuable anti-proliferative effect and some displayed a greater effect as compared to nitroxoline against three pancreatic cancer cell lines with different genetic profiles. In particular, in silico pharmacokinetic data, clonogenicity assays and selectivity indexes of the most promising compounds showed several advantages for such derivatives, as compared to nitroxoline. Moreover, some of these novel compounds had stronger effects on cell viability and/or clonogenic capacity in PC cells as compared to erlotinib, a targeted agent approved for PC treatment.

Synthesis and evaluation of biaryl derivatives for structural characterization of selective monoamine oxidase B inhibitors toward Parkinson's disease therapy

Benzyloxyphenyl moiety is a common structure of highly potent, selective and reversible inhibitors of monoamine oxidase B (MAO-B), safinamide and sembragiline. We synthesized 4-(benzyloxy)phenyl and biphenyl-4-yl derivatives including halogen substituents on the terminal aryl unit. In addition, we modified the carbon linker between amine group and the biaryl linked unit. Among synthesized compounds, 12c exhibited the most potent and selective MAO-B inhibitory effect (hMAO-B IC50: 8.9 nM; >10,000-fold selectivity over MAO-A) as a competitive inhibitor. In addition, 12c showed greater MAO-B inhibitory activity and selectivity compared to well-known MAO-B inhibitors such as selegiline, safinamide and sembragiline. In the MPTP-induced mouse model of Parkinson's disease (PD), 12c significantly protected the tyrosine hydroxylase (TH)-immunopositive DAergic neurons and attenuated the PD-associated behavioral deficits. This study suggests characteristic structures as a MAO-B inhibitor that may provide a good insight for the development of therapeutic agents for PD.

Design and Synthesis of 4-Anilinothieno[2,3-d]pyrimidine-Based Compounds as Dual EGFR/HER-2 Inhibitors

Dual inhibition of the epidermal growth factor receptor (EGFR) and the human epidermal growth factor receptor 2 (HER-2) is an attractive cancer therapeutic approach. In this study, new series of 4-anilinothieno[2,3-d]pyrimidines were designed, synthesized, and tested as dual EGFR/HER-2 kinase inhibitors. Five compounds (8a, 8b, 8e–g) demonstrated low to submicromolar inhibition of both kinases with IC50 values of 1.2, 0.6, 0.3, 0.2, 0.4 μM and 8.2, 3.4, 1.3, 0.5, 2.7 μM for the EGFR and HER-2, respectively. Introduction of a 5,6-tetramethylene moiety into the thienopyrimidine core bearing a 4-(3-fluorobenzyloxy)-3-chloroaniline tail resulted in a favorable increase in both the EGFR and HER-2 inhibitory activities. Compound 8f (IC50 EGFR/HER-2: 0.2/0.5 μM) also exhibited significant cell growth inhibition on some specific NCI cell lines, especially ovarian, breast, non-small-cell lung cancer, and renal cancer cell lines.

Fluorinated benzyloxyphenyl piperidine-4-carboxamides with dual function against thrombosis: Inhibitors of factor xa and platelet aggregation

A series of benzyloxy anilides of nipecotic (5, 6) and isonipecotic (7, 8) acids were synthesized and assayed in vitro as inhibitors of ADP-induced platelet aggregation and the blood coagulation enzymes factor Xa (FXa) and thrombin (Flla). An exploration of effects of the amidine group attached at the piperidine nitrogen, position and substitution (F, phenyl) of the benzyloxy group, and addition of fluorine/s on the second (distal) phenyl ring, led us to single out some promising isonipecotamide derivatives 7. Addition of meta-F and para-CF3 on the distal phenyl ring resulted in a 6-to-18-fold enhancement of the FXa potency and in 2-to- 4-fold increase of the antiplatelet potency, the last depending to a large extent upon lipophilicity. Two congeners of N-{[3-(1,1′-biphenyl-4-yl)methoxy]phenyljpiperidine-4-carboxamide (7m and 7p) proved to be potent FXa-selective inhibitors (Ki = 130 and 57 nM, respectively) and antiplatelet agents and were identified as leads for developing new dual function antithrombotic drugs.
