Discovery of 4?-(1,4-dihydro-indeno[1,2-c]pyrazol-3-yl)-benzonitriles and 4?-(1,4-dihydro-indeno[1,2-c]pyrazol-3-yl)-pyridine-2?-carbonitriles as potent checkpoint kinase 1 (Chk1) inhibitors

An extensive structure-activity relationship study of the 3-position of a series of tricyclic pyrazole-based Chk1 inhibitors is described. As a result, 4?-(1,4-dihydro-indeno[1,2-c]pyrazol-3-yl)-benzonitriles (4) and 4?-(1,4-dihydro-indeno[1,2-c]pyrazol-3-yl)-pyridine-2?-carbonitriles (29) emerged as new lead series. Compared with the original lead compound 2, these new leads fully retain the biological activity in both enzymatic inhibition and cell-based assays. More importantly, the new leads 4 and 29 exhibit favorable physicochemical properties such as lower molecular weight, lower Clog P, and the absence of a hydroxyl group. Furthermore, structure-activity relationship studies were performed at the 6- and 7-positions of 4, which led to the identification of ideal Chk1 inhibitors 49, 50, 51, and 55. These compounds not only potently inhibit Chk1 in an enzymatic assay but also significantly potentiate the cytotoxicity of DNA-damaging agents in cell-based assays while they show little single agent activity. A cell cycle analysis by FACS confirmed that these Chk1 inhibitors efficiently abrogate the G2/M and S checkpoints induced by DNA-damaging agent. The current work paved the way to the identification of several potent Chk1 inhibitors with good pharmacokinetics that are suitable for in vivo study with oral dosing.

Synthesis of Pyrano[2, 3-d]Pyrimidine-2,4(3H)-Dione Derivatives Based-on Curcumin Using NiCo2O4@OCMC@Zn(BDC) Nanocomposite as a Novel and Efficient Catalyst

Curcumin, a category of phenolic compound derivatives from the base of Curcuma longa (Zingiberaceae), represent a variety of beneficial effects on health and on events that succor in hampering certain diseases. The present research explains an efficient procedure for the synthesis of pyrano[2,3-d] pyrimidine-2,4(3H)-diones in high yields and short response times via a three-ingredient reaction of curcumin, aromatic aldehydes and 1,3-dimethylbarbituric acid in the presence of NiCo2O4@OCMC@Zn(BDC) nanocomposite. The catalyst was determined by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), Fourier transform infrared, (FT-IR) X-ray powder diffraction (XRD) and Brunauer?Emmett?Teller (BET). Moreover, the NiCo2O4@OCMC@Zn(BDC) catalyst can be recovered and reused several times without significant loss of its activity.

Chiral Pool/Henry/Enzymatic routes to acetogenin synthons

Enantio specific and enantioselective approaches to the natural (16 R,19R)- and the unnatural (16S,19S)- THF core of the bioactive acetogenin annonacin are described which utilizes both a chiral pool synthesis and enzymatic transformations. In the antipodal (2S,5S) THF series derived from D-(+)-glucosamine, the semi-protected THF aldehyde synthon allows for two-directional synthetic elaboration through a Henry reaction with a lipid-like nitroalkane. The resulting nitroalcohol having the unnatural (2S,5S)-THF core was oxidized to the corresponding a-nitroketone using a modified Collins oxidation. The intermediate a-nitroketone has potential for the preparation of the C15-C32 core and analogues through subsequent removal of the nitro group and reduction of the carbonyl.

Photo-oxidation of two malonamides, extractant models for minor actinides in nuclear fuel reprocessing

The photo-oxidation of two potential extractants, the N,N?-dimethyl, N, N?-dibutyl, tetradecyl malonamide (DMDBTDMA and the N, N ?-dimethyl, N, N?-dibutyl, dodecylethoxy malonamide (DMDBDDEMA) for minor actinides in nuclear fuel reprocessing was followed. The main photoproducts, identified by coupled techniques (GC/FTIR and GC/MS) are malonamides, monoamides and carbonylate derivatives. An irradiation, for 1 h, with a low mercury pressure lamp can destroy initial diamides diluted at 0.075 moll-1 in n-dodecane. With pure solutions of diamides (2.05 moll-1), destruction needs several hours to be complete. Both diamides only differ by an ether bond, their reactivity under different conditions of photo-oxidation is discussed.

Practical asymmetric synthesis of RO5114436, a CCR5 receptor antagonist

A practical asymmetric synthesis of a 3,7-diazabicyclo[3.3.0]octane derivative (1), a representative of a new class of potent CCR5 receptor antagonists, is described. The benzylamine stereogenic center of 1 was introduced by a ruthenium-catalyzed asymmetric reductive amination using (R)-MeOBIPHEP as ligand. Aldehyde 4, prepared by Parikh-Doering oxidation, was used without workup in the reductive amination reaction, which not only simplified the process but also overcame the instability of 4. The 3,7-diazabicyclo[3.3.0]octane core was obtained by a [3 + 2] cycloaddition.

Design, synthesis, and biological evaluation of substituted benzoate analogues of the selective nicotinic acetylcholine receptor antagonist, methyllycaconitine

The norditerpenoid alkaloid methyllycaconitine (MLA) acts as a competitive antagonist on the nicotinic acetylcholine receptor (nAChR) with a high preference for the neuronal alpha-bungarotoxin (alphaBgt)-sensitive nAChR over the muscle nAChR in mammals. MLA is thus a useful pharmacological tool. Furthermore, its efficient binding to insect nAChR indicates a high insecticidal potency. Within the complex hexacyclic structure of MLA, we envisaged a potential simple pharmacophore. This led to the design and synthesis of acyclic and monocyclic analogues of MLA. The biological activity of these derivatives at both neuronal nicotinic and muscarinic AChR was evaluated. Some of these structurally simple compounds, despite displaying a modest affinity for the nAChR, showed good specificity. We were able to show the importance of the 2-(methylsuccinimido)benzoate ester moiety and the E-ring of MLA. None of the analogues tested displayed any affinity for [3H]nicotine binding sites in brain membranes, indicating that alpha7-selectivity is already inherent in these simple structures. If higher affinities are to be obtained, however, there is a clear need for more structural information in the design of second generation simple analogues of MLA.
