Novel 5-HT3 antagonists. Isoquinolinones and 3-aryl-2-pyridones

Synthesis and pharmacological evaluation of a series of 1,2-dihydro-1-[(5- methyl-1-imidazol-4-yl)methyl]-2-oxopyridine 5-HT3 antagonists are described. The key pharmacophoric elements were defined as a basic nitrogen, a linking group capable of hydrogen bonding interactions, and an aromatic moiety. 1,2-Dihydro-2-oxopyridine moiety could be a good linking group because of its nicely planar structure. The steric limitations of the aromatic moiety were investigated by X-ray analysis and computer analysis and shown to be optimal when the aromatic moiety was constrained within an arched planar system, which could be successfully replaced by 3-(2-thienyl)-2- oxopyridine function or 6-amino-7-chloro-1-isoquinolinone function without any loss of the activity. Among the synthesized compounds, 42 showed the most potent activity in the inhibition of Bezold-Jarisch reflex in rats. Compounds 44a and 64 were orally active in the protection against cisplatin-induced emesis in dogs or ferrets. Structure-activity relationships are discussed.

One-pot alpha-arylation of beta-carboline with indole and naphthol derivatives

4,9-Dihydro-3H-beta-carboline and 6-methoxy-4,9-dihydro-3H-beta-carboline were subjected to catalyst-free one-pot alpha-arylation with 1-or 2-naphthol, 6-hydroxyquinoline or 5-hydroxyisoquinoline as N-containing analogues via direct aza-Friedel-Crafts reactions. The procedure was then extended to other electron-rich aromatic compounds, such as indole or indole-2-carboxylic acid, to yield new indole gamma-amino acid derivatives containing beta-carboline skeleton. All the reactions were performed both under neat conditions and with microwave irradiation. The reaction of 2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole and benzaldehyde with 1-naphthol as nucleophile led to the formation of the N-alkylated compound as a single product, whereas the reaction with 2-naphtol resulted in the two possible alpha-arylated/N-alkylated products, in a ratio depending on the reaction conditions.

Assessment of the cytotoxic effects of aporphine prototypes on head and neck cancer cells

Purpose Among alkaloids, abundant secondary metabolites in plants, aporphines constitute a class of compounds with interesting biological activities, including anticancer effects. The present study evaluated the anticancer activities of 14 substances, including four aporphine derivatives acquired through the biomonitoring of (¡À)-apomorphine hydrochloride total synthesis from 2-phenethylamine and 3,4-dimethoxybenzaldehyde against head and neck squamous cell carcinoma (HNSCC). Methods The cytotoxic effects of compounds against a panel of HNSCC cell lines were determined by PrestoBlue cell viability assay, while the genotoxicity of substances was evaluated by micronucleus test. Cell death was detected by flow cytometry (Annexin V/7AAD) and western blot analysis was used to detect the presence of cleaved Caspase-3 molecules. Results The aporphine and isoquinoline derivatives APO, C1, and A5 significantly reduced HNSCC cell viability and promoted DNA damages in these cells. Further, by activating the Caspase-3 pathway, these substances were able to induce apoptosis. Conclusion Our results revealed that APO, C1, and A5 exhibit cytotoxic effects in HNSCC cells. The mechanisms of action appear to be partly via the generation of DNA damages and apoptosis induction through Caspase-3 pathway activation. This study provides preclinical data that suggest a potential therapeutic role for APO, C1, and A5 against head and neck cancer cells.

Palladium-catalyzed oxidative CH/CH cross-coupling of pyridine N-oxides with five-membered heterocycles

Using Ag2CO3 as an additive, we developed the Pd-catalyzed intermolecular C-H/C-H cross-coupling of pyridine N-oxides with five-membered heterocycles such as 1-benzyl-1,2,3-triazoles, thiophens and furans. This protocol provides an efficient and regioselective approach for the synthesis of unsymmetrical biheteroaryl molecules.

Heterocyclic Monomers via Reissert Chemistry

An AA bisphenolic monomer (13), an AB activated fluoro-phenolic monomer (14), and an AB(2) alcohol-diester monomer precursor (17), all based on the isoquinoline nucleus, were prepared using Reissert compound chemistry. Additionally, model reactions established the efficiency of condensation of isoquinoline Reissert compounds with dihaloalkanes, providing evidence of the potential of this reaction to produce high molecular weight polymers, which was subsequently realized.

Electronic Spectra of Gas-Phase Polycyclic Aromatic Nitrogen Heterocycle Cations: Isoquinoline(+) and Quinoline(+)

Electronic spectra of the gas-phase isoquinoline(+)-Ar and quinoline(+)-Ar complexes are recorded using photodissociation spectroscopy by monitoring the Ar loss channel. The D-3 <- D-0 and D-4 <- D-0 band origins for isoquinoline(+)-Ar are observed at 15245 +/- 15 cm(-1) and 21960 +/- 15 cm(-1), respectively, whereas for quinoline(+)-Ar they appear at 16050 +/- 15 cm(-1) and 21955 +/- 15 cm(-1), respectively. Strong vibronic progressions for the D-3 <- D-0 band systems of both isoquinoline(+)-Ar and quinoline(+)-Ar are modeled and assigned in terms of ring deformation and carbon carbon stretch vibrational modes using time-dependent density functional theory calculations in conjunction with Franck-Condon simulations. The properties of the isoquinoline(+) and quinoline(+) molecules are compared with those of the isoelectronic naphthalene(+) molecule. The existence of strong progressions in the visible spectra of isoquinoline(+)-Ar and quinoline(+)-Ar suggests that the corresponding isoquinoline(+) and quinoline(+) molecular cations are unlikely to be responsible for diffuse interstellar bands.
