Kalogirou, Andreas S. published the artcileSynthesis and Reactivity of 3′,5′-Dichloro-1H-spiro(quinazoline-2,4′-[1,2,6]thiadiazin)-4(3H)-ones, Formula: C7H6N2, the main research area is chloro spiro quinazoline thiadiazine derivative synthesis reactivity.

A three-step synthesis of 3′,5′-dichloro-1H-spiro(quinazoline-2,4′-[1,2,6]thiadiazin)-4(3H)-ones starting from 3,4,4,5-tetra-chloro-4H-1,2,6-thiadiazine (I) is presented. The latter reacts with 2-aminobenzonitriles to give 2-[(3,5-dichloro-4H-1,2,6-thiadiazin-4-ylidene)amino]benzonitriles [e.g., I + 2-aminobenzonitrile → II (86%)] , which affords, after hydration, the resp. benzamides [II → III (84%)]. Upon heating at reflux in EtOH or HFIP, the benzamides intramolecularly cyclize onto the thiadiazine C4 position to give 3′,5′-dichloro-1H-spiro(quinazoline-2,4′-[1,2,6]thiadiazin)-4(3H)-ones [III → IV (95% in EtOH, 97% in HFIP)]. Single crystal X-ray crystallog. supports the structure of two analogs. The chloride displacement of these new spiroquinazolinones was demonstrated by Stille coupling, and by reaction with methoxide to afford both the mono and bis-methoxy derivatives

Lappert’s stannylene (Sn[N(SiMe3)2]2) has been reacted with various nitriles, dinitriles and trinitriles with the formation of heteroleptic amidotin(II) amidinates of the general formulas [RC(NSiMe3)2]SnN(SiMe3)2, R'{[C(NSiMe3)2]SnN(SiMe3)2}2 and R”{[C(NSiMe3)2]SnN(SiMe3)2}3, where R = Ph (1), 2-(CN)-C6H4 (2), 3-(CN)-C6H4 (3); R’ = 1,3-C6H4 (4), 1,4-C6H4 (5) and R” = 1,3,5-C6H3 (6). The reactions of amidotin(II) benzamidinate 1 with an excess of benzonitrile proceed to homoleptic tin(II) bis(benzamidinate) [PhC(NSiMe3)2]2Sn, which reversibly eliminates benzonitrile and 1 when warmed. The premise of reversibility has been supported by a multinuclear time-dependent NMR study and a theor. (DFT) description. On the other hand, magnesium(II) bis(benzamidinate) [PhC(NSiMe3)2]2Mg (8) and lanthanum(II) tris(benzamidinate) [PhC(NSiMe3)2]3La (7) have been synthesized from appropriate metal hexamethyldisilazides and benzonitrile.

These compounds showed satisfactory potencies with much higher anticancer activity than the parent compound DCA, against the studied cancer cell lines. Mol. docking studies were also done to find their binding site and types of their interactions with PDKs isoenzymes. Among the synthesized compounds, compound I can also induce A549 cells apoptosis. Therefore, compound I might have a potential value for further study in drug development. QSAR studies of this class of compounds were also explored using a collection of chemometrics methods.

Baechle, Felix published the artcileGlycoconjugated Phthalocyanines as Photosensitizers for PDT – Overcoming Aggregation in Solution, Synthetic Route of 91-15-6, the main research area is glycoconjugated zinc phthalocyanine complex preparation CD spectra fluorescence; cytotoxicity activity glycoconjugated zinc phthalocyanine complex.

A series of new glycoconjugated zinc(II) phthalocyanines (Pcs) was synthesized and fully characterized. The major focus of the structural design for these new Pcs was upon the reduction of aggregate formation in solution Therefore, the aglycons of the Pc-linked sugars, the number and the position of the carbohydrate substituents on the Pc and the linker between sugar and Pc were varied. Specifically, di- and octasubstituted zinc(II) phthalocyanines with triazole and C-C linkages were synthesized and their aggregation behavior was investigated by UV/visible-, CD- and NMR spectroscopy. The C-glycosidically decorated Pcs described here are the first compound types of this kind. These C-glycosidically substituted Pcs not form any aggregation in solution and hence, are considered to be potential photosensitizers in photodynamic therapy. All Pcs synthesized in this study exhibited excellent photophys. properties for use as photosensitizers (λmax > 675 nm with εmax > 105 M-1 cm-1). Preliminary cytotoxicity studies of the Pcs presented here showed that all Pcs are photodynamically effective.

Tlusty, M. published the artcileRegioselective formation of the quinazoline moiety on the upper rim of calix[4]arene as a route to inherently chiral systems, Synthetic Route of 100-70-9, the main research area is calixarene quinazoline conformation crystal structure pi interaction inclusion compound.

The meta- and para-substituted aminocalix[4]arenes immobilized in the cone conformation were acylated to yield the corresponding acyl amides. Subsequent cyclization with aryl or alkyl cyanides afforded the expected quinazolines only in the case of the para-substituted series, while only complex reaction mixtures were obtained for the meta-substituted analogs. This finding was used as a strategy for the preparation of novel inherently chiral calixarenes with strong fluorescence. The structure of the products was proved by the combination of NMR and single crystal X-ray analyses. The dynamic NMR study of quinazoline derivatives revealed the existence of two different atropisomers in solution at lower temperatures As evidenced by resolution with a chiral HPLC column and by the fluorescence titration experiments, novel quinazolines represent inherently chiral macrocycles of high potential for the design of chiral calixarene-based receptors.

Sharma, Swagat published the artcileDiscovery, synthesis and characterization of a series of (1-alkyl-3-methyl-1H-pyrazol-5-yl)-2-(5-aryl-2H-tetrazol-2-yl)acetamides as novel GIRK1/2 potassium channel activators, Category: nitriles-buliding-blocks, the main research area is pyrazolyl arylazolyl acetamide preparation GIRK channel activator SAR; Activator; G protein-regulated inwardly-rectifying potassium channel; GIRK; Tetrazole.

The study described the discovery and characterization of a series of 5-aryl-2H-tetrazol-3-yl acetamides as G protein-gated inwardly-rectifying potassium (GIRK) channels activators. Working from an initial hit discovered during a high-throughput screening campaign, a tetrazole scaffold was identified that shifts away from the previously reported urea-based scaffolds while remaining effective GIRK1/2 channel activators. In addition, the compounds were evaluated in Tier 1 DMPK assays and identified a (3-methyl-1H-pyrazol-1-yl)tetrahydrothiophene-1,1-dioxide head group that imparts interesting and unexpected microsomal stability compared to previously-reported pyrazole head groups.

An novel high affinity multi-target directed ligands (MTDLs) against AChE and NMDAR, with reduced hepatotoxicity, performed in-silico structure-based modifications on tacrine, chem. synthesis of the derivatives and in-vitro validation of their activities. Nineteen such derivatives I [R = H, methylcarbamoyl, hydrazinecarbonyl, ethoxycarbonyl; R1 = 2-furanyl, 1-methylpyrazol-4-yl, 2-FC6H4, etc.] showed inhibition with IC50 values in the range of 18.53 ± 2.09 – 184.09 ± 19.23 nM against AChE and 0.27 ± 0.05 – 38.84 ± 9.64μM against NMDAR. Some of the selected compounds protected rat primary cortical neurons from glutamate induced excitotoxicity. Two of the tacrine derived MTDLs, I [R = H, R1 = 1-methylpyrazol-4-yl; R = H, R1 = 2-FC6H4] exhibited in-vivo efficacy in rats by protecting against behavioral impairment induced by administration of the excitotoxic agent, monosodium glutamate. Addnl., several of these synthesized compounds also exhibited promising inhibitory activitiy against butyrylcholinesterase. MTDL-201 I [R = H, R1 = 1-methylpyrazol-4-yl] was also devoid of hepatotoxicity in-vivo. Given the therapeutic potential of MTDLs in disease-modifying therapy, studies revealed several promising MTDLs among which I [R = H, R1 = 1-methylpyrazol-4-yl] appeared to be a potential candidate for immediate preclin. evaluations.
