Аннотация: A series of 4,5-diphenyl-7H-thieno[2′,3′:3,4]pyrido[2,1-b]quinazolin-7-ones was synthesized via the Rh(III)-catalyzed annulation of 2-thienylquinazolin-4(3H)-ones with diphenylacetylene. 2-Phenylquinazolin-4(3H)-one amide alcoholysis and double C–H functionalization proceeded under the same reaction conditions with the formation of 2,3,7,8-tetraphenyl-1H-benzo[d,e][1,8]-naphthyridine derivatives. All compounds possess fluorescence properties in MeCN and toluene solutions as well as in the solid state. The aggregation induced emission (AIE) properties and the ability to detect Fe3+ cations were evaluated.

Аннотация: Novel N,O-bidentate BF2 and BPh2 complexes have been prepared in good to excellent yields through coordination of 8-hydroxy-2-methylquinolines and 2-(2-hydroxyphenyl)-3H-quinazolin-4-ones with boron trifluoride etherate or triphenylborane under mild conditions. All complexes have been characterized by H-1, B-11 and F-19 NMR, mass-spectrometry and X-ray crystallography data. Some complexes have been found to exhibit a significant fluore.scence in acetonitrile solutions. Electronic and site effects of substituents in both heterocyclic and phenol fragments proved to have a profound impact on quantum yields.

Аннотация: 5-Fluoroquinazoline-2,4-diones and their 2-thio analogs were obtained from 6-fluoroanthranilic acid. Two convenient routes to 5-fluoroquinazolin-4-ones involved cyclocondensation of 6-fluoroanthranilamide with acid chlorides (anhydrides) or with aromatic (heterocyclic) aldehydes. A method for the synthesis of 7-fluoroquinazolin-4-one from 2,4-difluorobenzoic acid was proposed

Аннотация: A rapid development of the resistance of drugs and their toxic and adverse reactions suggest that new antituberculous drugs should be designed. Of the greatest importance is isoniazid resistance. Testing new compounds (IIa, b) has established that the minimum inhibitory concentration of the drug (IIa), 0.39 microgram/ml suppresses the growth of Mycobacterium tuberculosis (MBT) in the macrophages up to 50%, that of the drug (IIb), 1.56 micrograms/ml, causes death in 25% of cases, which is indicative of the high activity of compounds (IIa, b) against MBT

CROSS-COUPLING -- DIBENZO[F,H]QUINOXALINE -- DONOR-ACCEPTOR-DONOR CHROMOPHORES -- FLUORESCENCE -- SENSORS
Аннотация: A series of novel V-shaped luminophores containing electron-withdrawing dibenzo[f,h]quinoxaline core and arylthienyl donor fragments at positions 2 and 3 has been synthesized. The absorption spectra (UV/vis) were recorded in several solvents, whereas emission spectra were recorded in solutions and powders. The solvatochromism as well as halochromism of obtained compounds was also explored. Electronic-structure calculations using quantum-chemistry methods were performed to further analyse experimental results. All characteristics were compared with that of 2,3-bis(arylthienyl)quinoxaline counterparts. The halochromic effect studies showed that upon gradual addition of trifluoroacetic acid (TFA) to the toluene solution of diethylaminophenyl-substituted dibenzo[f,h]quinoxaline chromophore, absorption and emission changed. Observed band shifts were more distinct in the case of mentioned quinoxaline than for other derivatives. All of the (dibenzo[f,h])quinoxaline chromophores exhibited good sensitivity toward nitro-containing explosives with high Stern-Volmer constants up to 57800 M−1, these results are remarkable for such heterocyclic systems.

PHOTOPHYSICS -- CHARGE TRANSFE -- FLUORESCENCE
Аннотация: The synthesis of a series of push-pull aryl and arylethynyl 2-(thiophen-2-yl) quinazoline derivatives is presented. The photophysical properties of the newly generated compounds are also described. Functionalization of the (2-thienyl) quinazoline fluorophore at the 5'-position with aryl and arylethynyl moieties was performed using bromination and subsequent palladium-catalyzed cross-coupling reactions. Optical studies revealed that 4-(diethylamino) phenyl and 4-(diphen-ylamino) phenyl derivatives emit green light upon irradiation, whereas their 4-(9H-carbazol-9-yl) phenyl, methoxyphenyl, thienyl and arylethynyl counterparts are characterized by blue light emission capabilities. The effect of protonation has also been studied, and the ability of some of these molecules to function as colorimetric and luminescent pH sensors has been demonstrated with significant color changes and luminescence switching upon the introduction of acid.

ANTIVIRAL ACTIVITY -- 4-ARYLAMINOQUINAZOLINES -- INTRAMOLECULAR CYCLIZATIONS
Аннотация: 2-Methylthio-4-phenylamino-6,7,8-trifluoro-3H-quinazolin-4-one was synthesized by means of intramolecular cyclizations of S-methyl-N-(tetrafluorobenzoyl)isothiourea followed by a reaction with POCl3 and nucleophilic substitution at the 4-position. The reactions of the synthesized compound with amines proceed, depending on their nature, via substitution of either the F(7) atom or the SMe fragment in the 2-position. The antiviral activity of the obtained 6,7,8-trifluoro-2-ethylthioquinazolin-4-ones was investigated using monkeypox virus, smallpox vaccine, and ectromelia virus. It is shown that fluorinated quinazoline derivatives have good prospects in the search for new active substances

Аннотация: Scieces of data on the synthesis and antitumour activity of 4-aminoquinazolines are summarized and analyzed. Key methods for the synthesis of these compounds are considered, primarily cyclocondensation of carboxylic acid derivatives, as well as the oxidation of quinazolines and the cyclization of disubstituted thioureas. Improvements of synthetic schemes for erlotinib, gefitinib and lapatinib, which are the best-known pharmaceuticals based on compounds of the title class, are also considered. Synthetic strategies and biological activities for new 4-aminoquinazoline derivatives that are EGFR-tyrosine kinase inhibitors, multiactive compounds, and labelled compounds for use as positron emission tomography (PET) imaging agents are discussed.

ESIPT -- FLUORESCENCE -- O-LIGAND -- BF2-COMPLEX2-(2-HYDROXYPHENYL)–3H-QUINAZOLIN-4-ONES
Аннотация: 2-(2-Hydroxyphenyl)–3H-quinazolin-4-ones with diverse substituents at phenol ring and their six-membered difluoroboron complexes have been synthesized via few-stage approach. The photophysical properties of target compounds have been investigated in two solvents as well as in the solid state. The nature of substituents and substitution point in the phenol moiety of ligands and resulting BF2-complexes on the photophysical properties of dyes have been explored. The complex bearing two t-Bu groups proved to be the most emissive in solid state, whereas its 5-methoxy and 4-diethylamino counterparts possess strong emission in toluene solution. The dyes exhibited large Stokes shifts which was attributed to excited state intramolecular proton transfer (ESIPT). Additionally, fluorescence of quinazolinones in the mixture of THF/water was studied. All ligands demonstrated emission enhancement with increase of water fraction which was due to aggregation induced emission.
