CuBr2 catalyzed bromination/oxidation of isochromans to benzaldehyde derivatives

A series of isochromans were oxidized and brominated by using 1.2 equiv of CuBr2 in CH3CN at reflux to give the corresponding bromo benzaldehydes in moderate yields. A plausible mechanism for this transformation has been suggested.

Unexpected Oxidative Ring Opening of Electron-Rich 3-Aminobenzofurans into alpha-Ketoimines Derivatives

An unexpected ring opening of 3-aminobenzofurans promoted by NaOtBu in hot toluene, leading to a variety of alpha-ketoimines, is described. In the presence of 3-iodobenzofurans, NaOtBu mediates the 3-aminobenzofurans ring opening via a possible radical pathway without the help of any external radical sources.

Interrupted imino-nazarov cyclization of 1-aminopentadienyl cation and related cascade process

Facile 4pi conrotatory imino-Nazarov cyclization of a 1-aminopentadienyl cation generated from condensation an aldehyde and secondary aniline in the presence of a catalytic amount of a Lewis acid has been developed. Silver(I)-catalyzed intramolecular arene trapping of the resulting cyclic oxyallyl cation leads to formation of tricyclic indoline-fused cyclopentanone. The use of lanthanide salts allows transformation after the initial trapping to afford tetrahydroquinoline-fused cyclopentenone in a concise manner. Taking control: The fate of an oxyallyl cation formed through a 4pi conrotatory imino-Nazarov cyclization can be controlled to access cyclopentanoid frameworks. In the presence of silver(I), intramolecular arene trapping leads to indoline-fused cyclopentanones. Gadolinium(III) facilitates a cascade transformation to furnish tetrahydroquinoline-fused cyclopentenones. Tf=trifluoromethanesulfonyl.

Effect of O6-substituted guanine analogs on O6-methylguanine DNA-methyltransferase Expression and glioblastoma cells viability

Background: Glioblastoma multiforme (GBM) is often associated with a poor survival prognostic for patients. The main reason seems to be the acquired or inherent resistance to the chemotherapeutic agent used to treat the tumor, temozolomide (TMZ). To this day, the most recognized pathway of resistance is the DNA Direct Repair pathway by the means of the protein O6-methylguanine DNA-methyltransferase (MGMT). Objectives: To design and synthesize a series of MGMT inhibitors that can sensitize GBM cells to TMZ. Methods: Twenty-five O6-alkyl, O6-aryl and O6-substituted-aryl guanine analogs including nine novel compounds were synthesized, characterized, analyzed by molecular docking and tested on the T98G GBM cells viability. Results: Following molecular modeling with MGMT, the newly designed compounds 19, 22, and 24 emerged as the most promising MGMT ligands and displayed modest cytotoxicity. Guanine analog (19), bearing a p-nitrobenzyl moiety, reduced considerably the O6-methylguanine DNA-methyltransferase expression level. When combined with TMZ (1), which is used as first line treatment for brain tumors, compounds 19, 22, and 24 decreased T98G cellsoproliferation by 32%, 68% and 50%, respectively. TMZ (1) displayed negligible effect on the proliferation of these cells further supporting the notion that this cell model is resistant to this alkylating agent. Conclusion: Overall, these results notably highlight a group of MGMT inhibitors that warrants further exploration in the development of therapeutic options to circumvent TMZ resistance in brain tumors.

1,4-Benzodioxane, an evergreen, versatile scaffold in medicinal chemistry: A review of its recent applications in drug design

1,4-Benzodioxane has long been a versatile template widely employed to design molecules endowed with diverse bioactivities. Its use spans the last decades of medicinal chemistry until today concerning many strategies of drug discovery, not excluding the most advanced ones. Here, more than fifty benzodioxane-related lead compounds, selected from recent literature, are presented showing the different approaches with which they have been developed. Agonists and antagonists at neuronal nicotinic, alpha1 adrenergic and serotoninergic receptor subtypes and antitumor and antibacterial agents form the most representative classes, but a variety of other biological targets are addressed by benzodioxane-containing compounds.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

N,N-bis-heteroaryl methylamines: Potent anti-mitotic and highly cytotoxic agents

The synthesis and evaluation of a series of N,N-bis-heterocyclic-methylamines 1 as isoazaerianin analogues are described. It was demonstrated that the replacement of the 3,4,5-trimethoxyphenyl A-ring present in CA-4, isoCA-4 and isoazaerianin by a quinoline or a quinazoline ring is possible and often beneficiary for a high level of cytotoxicity. We have also showed that a carbazole or an indole nucleus are very effective as B-rings in this series, leading to anti-cancer drugs 1 having a sub-nanomolar level of cytotoxicity (1a: IC50 = 70 pM against HCT116 cells). 1a also display a high level of cytotoxicity against four other human cancer cells and inhibited tubulin assembly at a micromolar level. Moreover, at a concentration of 5 nM, 1a arrested the cellular cycle in G2/M phase of the cellular cycle and induced apoptosis of HCT116 cells. It was also showed that after few hours 1a at a concentration of 10 nM totally disrupted endothelial network formation on Matrigel.

Selective synthesis of substituted benzylic alcohols from aromatic substrates included in beta-cyclodextrin

The regio- and enantioselective reduction of substituted styrenic epoxides and aromatic ketones by borohydride in the presence of beta-cyclodextrin is described. The regioselectivity is related to the hydrophobicity of the substrate, which governs its penetration inside the cavity of the cyclodextrin and is favorable to the beta-opening of the epoxide. The stereoselectivity observed during the reduction is mainly dependent on the non-covalent interactions between the upper rim of the cyclodextrin and the substrate included in it. The chimioselectivity observed during the reduction of ketoester is assumed to be dependent on an alkoxyborohydride intermediate formed in the first step of the reaction. Elsevier.

Synthesis, biological evaluation and quantitative structure-active relationships of 1,3-thiazolidin-4-one derivatives. A promising chemical scaffold endowed with high antifungal potency and low cytotoxicity

With reference to recent studies reporting on the various biological properties of the thiazolidinone scaffold, we synthesized more than a hundred compounds characterized by a 1,3-thiazolidin-4-one nucleus derivatised at the C2 with a hydrazine bridge linked to (cyclo)aliphatic or hetero(aryl) moieties, and their N-benzylated derivatives. These molecules were assayed as potential anti-Candida agents and they were shown to possess comparable, and in some cases higher biological activity than well-established topical and systemic antimycotic drugs (i.e. clotrimazole, fluconazole, ketoconazole, miconazole, tioconazole, amphotericin B). Compounds endowed with the lowest MICs underwent further testing in order to assess their cytotoxic effect (CC50) on Hep2 cells, which demonstrated their relative safety. Finally, QSAR and 3-D QSAR models were used to predict putative chemical modifications of the 1,3-thiazolidin-4-one scaffold in order to design new and potential more active compounds against Candida spp.
