Phthalazinone pyrazoles as potent, selective, and orally bioavailable inhibitors of Aurora-A kinase

The inhibition of Aurora kinases in order to arrest mitosis and subsequently inhibit tumor growth via apoptosis of proliferating cells has generated significant discussion within the literature. We report a novel class of Aurora kinase inhibitors based upon a phthalazinone pyrazole scaffold. The development of the phthalazinone template resulted in a potent Aurora-A selective series of compounds (typically >1000-fold selectivity over Aurora-B) that display good pharmacological profiles with significantly improved oral bioavailability compared to the well studied Aurora inhibitor VX-680.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 19064-73-4, you can also check out more blogs about19064-73-4

Imidazo[4,5-b]pyridyl quinolone cardiac stimulants

A series of novel heterobicyclic substituted 2-(1H)-quinolone compounds have been prepared, including the 3,4-dihydro derivatives thereof, wherein the heterobicyclic ring moiety is an optionally-substituted indolyl, phthalizinyl, benzimidazolyl, imidazopyridinyl, quinolinyl or isoquinolinyl group attached by an nitrogen or carbon atom of said group to the 6-position of the quinolone ring. The optional substituent is a C1 -C14 alkyl group located on either of the two heterobicyclic rings and/or an oxo group situated on the heterocyclic portion of said heterobicyclic ring system. These particular compounds are useful in therapy as cardiac stimulants and therefore, are of value in the treatment of various cardiac conditions. 6-{1(H)-Imidazo[4,5-b]pyridin-6-yl}-8-methyl-2-(1H)-quinolone represents a typical and preferred member compound.

Synthesis and biological evaluation of 2,4-disubstituted phthalazinones as Aurora kinase inhibitors

A series of 2,4-disubstituted phthalazinones were synthesized and their biological activities, including antiproliferation, inhibition against Aurora kinases and cell cycle effects were evaluated. Among them, N-cyclohexyl-4-((4-(1-methyl-1H-pyrazol-4-yl)-1-oxophthalazin-2(1H)-yl) methyl) benzamide (12c) exhibited the most potent antiproliferation against five carcinoma cell lines (HeLa, A549, HepG2, LoVo and HCT116 cells) with IC50 values in range of 2.2?4.6 muM, while the IC50 value of reference compound VX-680 was 8.5?15.3 muM. Moreover, Aurora kinase assays exhibited that compound 12c was potent inhibitor of AurA and AurB kinase with the IC50 values were 118 ¡À 8.1 and 80 ¡À 4.2 nM, respectively. Molecular docking studies indicated that compound 12c forms better interaction with both AurA and AurB. Furthermore, compound 12c induced G2/M cell cycle arrest in HeLa cells by regulating protein levels of cyclinB1 and cdc2. These results suggested that 12c is a promising pan-Aurora kinase inhibitor for the potential treatment of cancer.

Development of novel proteasome inhibitors based on phthalazinone scaffold

In this study we designed a series of proteasome inhibitors using pyridazinone as initial scaffold, and extended the structure with rational design by computer aided drug design (CADD). Two different synthetic routes were explored and the biological evaluation of the phthalazinone derivatives was investigated. Most importantly, electron positive triphenylphosphine group was first introduced in the structure of proteasome inhibitors and potent inhibition was achieved. As 6c was the most potent inhibitor of proteasome, we examined the structure-activity relationship (SAR) of 6c analogs.

The synthesis of a series of new alkylsulfanyl phthalazinone and phthalazine derivatives is described. The target compounds were efficiently synthesized in a four step sequence, consisting of (1) cyclization of 2-formylbenzoic acid with hydrazine hydrate to form phthalazinone, (2) the direct bromination of phthalazinone core with KBr3, (3) alkylation of the obtained 4-bromolactam (Mitsunobu procedure) to make N- and also O-alkyl derivatives and finally (4) palladium-catalyzed coupling reactions of 2-alkyl-4-bromophthalazinone and 1-alkyloxy-4-bromophthalazine derivatives with aliphatic mercaptanes.

(Chemical Equation Presented). An efficient regioselective synthesis of substituted 4-alkylamino and 4-arylaminophthalazin-1(1H)-ones 5 is described. This new method features the formation of substituted phthalazin-1(1H)-ones 3 by the reaction of 2-formylbenzoic acids 1 or 3-hydroxyisobenzofuran-1(3H)-ones 2 with hydrazine to generate phthalazin-1(2H)-ones 3.

Rational design, green synthesis, and initial evaluation of a series of full-color tunable fluorescent dyes enabled by the copper-catalyzed N-arylation of 6-phenyl pyridazinones and their application in cell imaging

There is widespread interest in the application, optimization, and evolution of the transition-metal-catalyzed arylation of N-heteroarenes to discover full-color tunable fluorescent core frameworks. Inspired by the versatile roles of pyridazinone in organic synthesis and medicinal chemistry, herein, we report a simple and efficient copper-catalyzed cross-coupling reaction for the N-functionalization of pyridazinones in neat water. To achieve the efficient conversion of pyridazinones and organic halides in aqueous phase, a series of copper-salen complexes composed of different Schiff base ligands were investigated by rational design. A final choice of fine-tuned hydrophilicity balanced with lipophilicity among the candidates was confirmed, which affords excellent activity towards the reaction of a wide range of pyridazinones and organic halides. More importantly, the products as N-substituted pyridazinones were synthesized rationally by this methodology as full-color tunable fluorescent agents (426-612 nm). The N2 position of pyridazinones was modified by different aryl group such as benzothiazole, N,N-dimethylaniline, 3-quinoline, 4-isoquinoline and 2-thiophene, resulting in a series of full-color tunable fluorescent reagents. Meanwhile, the effects of electron-donating and electron-withdrawing groups of the 6-substituted phenyl ring have also been investigated to optimize the fluorescent properties. These fluorescent core frameworks were studied in several cell lines as fluorescent dyes. Different colors from blue to red were observed by using fluorescence microscopy and confocal microscopy. Colorful cores: A simple and efficient copper-catalyzed cross-coupling reaction for the N-functionalization of pyridazinones in neat water is reported (see figure). The N2 position of pyridazinones was modified by different aryl groups (R1), such as benzothiazole, N,N-dimethylaniline, 3-quinoline, 4-isoquinoline, and 2-thiophene, resulting in a series of full-color tunable fluorescent reagents.

Rational Design of Fluorescent Phthalazinone Derivatives for One- and Two-Photon Imaging

Phthalazinone derivatives were designed as optical probes for one- and two-photon fluorescence microscopy imaging. The design strategy involves stepwise extension and modification of pyridazinone by 1) expansion of pyridazinone to phthalazinone, a larger conjugated system, as the electron acceptor, 2) coupling of electron-donating aromatic groups such as N,N-diethylaminophenyl, thienyl, naphthyl, and quinolyl to the phthalazinone, and 3) anchoring of an alkyl chain to the phthalazinone with various terminal substituents such as triphenylphosphonio, morpholino, triethylammonio, N-methylimidazolio, pyrrolidino, and piperidino. Theoretical calculations were utilized to verify the initial design. The desired fluorescent probes were synthesized by two different routes in considerable yields. Twenty-two phthalazinone derivatives were synthesized and their photophysical properties were measured. Selected compounds were applied in cell imaging, and valuable information was obtained. Furthermore, the designed compounds showed excellent performance in two-photon microscopic imaging of mouse brain slices.
