Synthesis and biological evaluation of N-aryl-7-methoxybenzo[b]furo[3,2-d] pyrimidin-4-amines and their N-arylbenzo[b]thieno[3,2-d]pyrimidin-4-amine analogues as dual inhibitors of CLK1 and DYRK1A kinases

Novel N-aryl-7-methoxybenzo[b]furo[3,2-d]pyrimidin-4-amines (1) and their N-arylbenzo[b]thieno[3,2-d]pyrimidin-4-amine analogues (2) were designed and prepared for the first time via microwave-accelerated multi-step synthesis. Various anilines were condensed with N?-(2-cyanaryl)-N,N- dimethylformimidamide intermediates obtained by reaction of 3-amino-6- methoxybenzofuran-2-carbonitrile (3) and 3-amino-6-methoxybenzothiophene-2- carbonitrile (4) precursors with dimethylformamide dimethylacetal. The inhibitory potency of the final products against five protein kinases (CDK5/p25, CK1delta/epsilon, GSK3alpha/beta, DYRK1A and CLK1) was estimated. Compounds (2a-z) turned out to be particularly promising for the development of new pharmacological dual inhibitors of CLK1 and DYRK1A kinases.

Synthesis and phosphodiesterase 5 inhibitory activity of novel phenyl ring modified sildenafil analogues

New sildenafil analogues containing an ether ring fused into the phenyl moiety, 6a-d and 7a-d, were efficiently synthesized from the readily available starting materials, 1a-d and 2, in five steps. Ab initio calculations indicated that introduction of a cyclic ether to the phenyl group might enhance the co-planarity of the molecule. The torsional angles were calculated to be 2-3 for the 5-membered cyclic ether derivatives, 6a, 6c, 7a, and 7c, and 12-16 for the 6-membered ones, 6b, 6d, 7b, and 7d. On the other hand, sildenafil showed the least co-planarity with the torsional angle of 23 compared with the target compounds, 6a-d and 7a-d. in the enzyme assay, however, the in vitro PDE 5 inhibitory activity was found out to be inversely related to the degree of co-planarity. In other words, the least planar sildenafil showed the highest actiivty, and the most planar 5-membered cyclic ether derivatives were least active by 100-200-fold compared with sildenafil. Our study clearly demonstrated that the open chain 2′-alkoxy group of the phenyl ring, although less effective for inducing the co-planarity, seemed to act as a much better lipophilic requirement than the cyclic alkoxy moiety.

Synthesis and biological investigation of 2,4-substituted quinazolines as highly potent inhibitors of breast cancer resistance protein (ABCG2)

Expression of ABCG2, a member of the ABC transporter superfamily, has been correlated to the clinical outcome of multiple cancers and is often associated with the occurrence of multidrug resistance (MDR) in chemotherapy. Inhibition of the transport protein by potent and selective inhibitors might be a way to treat cancer more efficiently and improve the therapy of cancer patients. Recently we reported the synthesis of new inhibitors based on a quinazoline scaffold. In the present study more structural variations were explored. Compounds with 3,4-dimethoxy groups and meta or para nitro substituents were found to be highly potent inhibitors of ABCG2. The most potent compound was more than five-fold more potent than Ko143, one of the best inhibitors of ABCG2. To determine the new compounds selectivity toward ABCG2 their inhibitory effects on ABCB1 and ABCC1 were also investigated identifying selective as well as broadspectrum inhibitors. Furthermore, intrinsic cytotoxicity and efficacy regarding the reversal of multidrug resistance toward SN-38 and mitoxantrone were explored. The most potent compounds were able to reverse the resistance toward the cytostatic agents with EC50 values below 20 nM. Additionally, the type of interaction between inhibitors and the ABCG2 substrate Hoechst 33342 was investigated yielding competitive and non-competitive interactions suggesting different modes of binding. Finally the effect of the derivatives on vanadate-sensitive ATPase activity of ABCG2 was determined. According to the different effects on ATPase activity we conclude the existence of different binding sites. This study provides the structural requirements for high potency inhibition and elucidates the interaction with ABCG2 setting the basis for further studies.

Cyclic Iodine Reagents Enable Allylic Alcohols for Alkyl Boronate Addition/Rearrangement by Photoredox Catalysis

All-carbon quaternary centers are prevalent in bioactive small molecules. However, their efficient construction remains a formidable synthetic challenge. Here we report cyclic iodine(III) reagents enable the synthesis of cyclopentanones, cyclohexanones, and dihydrofuranones bearing alpha-quaternary centers by photoredox catalysis. The reaction proceeds by the formation of the novel cyclic iodine(III) reagent-allylic alcohol complex, which enables the first alkyl boronate addition and semi-pinacol rearrangement of allylic alcohols with dual alcohol and olefin activation. The reaction is suitable for gram scale synthesis and is transformable to alcohols, olefins, oximes, and lactones with an alpha-quaternary center in one step.

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.category: benzodioxans, you can also check out more blogs about39270-39-8

PIFA-Promoted, Solvent-Controlled Selective Functionalization of C(sp2)-H or C(sp3)-H: Nitration via C-N Bond Cleavage of CH3NO2, Cyanation, or Oxygenation in Water

A novel nitration (via C(sp3)-N breaking/C(sp2)-N formation with CH3NO2) mediated by [bis(trifluoroacetoxy)iodo]benzene (PIFA) is described. The NO2 transfer from CH3NO2 to the aromatic group of the substrate is possible with careful selection of the solvent, NaX, and oxidant. In addition, the solvent-controlled C(sp2)-H functionalization can shift to an alpha-C(sp3)-H functionalization (cyanation or oxygenation) of the alpha-C(sp3)-H of cyclic amines.

3-Phenylpropanoic acid-based phosphotyrosine (pTyr) mimetics: Hit evolution to a novel orally active protein tyrosine phosphatase 1B (PTP1B) inhibitor

Protein tyrosine phosphatase 1B (PTP1B) is a promising therapeutic target for type 2 diabetes. Herein, we report the evolution of a previously identified 3-phenylpropanoic acid-based PTP1B inhibitor to an orally active lead compound. A series of 3-phenylpropanoic acid-based PTP1B inhibitors were synthesized, and three of them, 3-(4-(9H-carbazol-9-yl)phenyl)-5-(3,5-di-tert-butyl-4- methoxyphenyl)-5-oxopentanoic acid (9), 3-(4-(9H-carbazol-9-yl)phenyl)-5- (4?-bromo-[1,1?-biphenyl]-4-yl)-5-oxopentanoic acid (10) and 3-(4-(9H-carbazol-9-yl)-2-fluorophenyl)-5-(4-cyclohexylphenyl)-5-oxopentanoic acid (16), showed IC50 values at sub-micromolar level. Further in vivo evaluation indicated the sodium salt of 9 not only exhibited significant insulin-sensitizing and hypoglycemia effects, but also decreased the serum levels of triglyceride and total cholesterol in high-fat-diet-induced insulin resistance model mice. Preliminary in vivo pharmacokinetic studies on the sodium salt of 9 revealed its pharmacokinetic profile after oral administration in rats. These results provide proof-of-concept for the dual effects of PTP1B inhibitors on both glucose and lipid metabolisms. A sincere form of flattery: A novel protein tyrosine phosphatase 1B (PTP1B) inhibitor with a 3-phenylpropanoic acid moiety as a phosphotyrosine (pTyr) mimetic was optimized to provide an orally active lead compound with an IC50 value of 0.40 muM against PTP1B and more notably that displayed significant in vivo activity in a murine insulin resistance model.

An Efficient Synthesis of Polysubstituted Pyridines via C sp 3 -H Oxidation and C-S Cleavage of Dimethyl Sulfoxide

An expedient cleavage of the C-S bond of dimethyl sulfoxide (DMSO) has been developed for the preparation of substituted pyridines from ketones. In this transformation, the co-product formic acid was formed from ammonium formate, which acted as an important catalyst for the reaction. Notably, this transformation exhibited a broad substrate scope towards a wide variety of different ketones to give the corresponding substituted pyridines in high yields. Mechanistic studies suggested that dimethyl sulfoxide delivered a methylene fragment, which was subsequently captured in situ to give a pyridine.

Targeted fluorination with the fluoride ion by manganese-catalyzed decarboxylation

We describe the first catalytic decarboxylative fluorination reaction based on the nucleophilic fluoride ion. The reported method allows the facile replacement of various aliphatic carboxylic acid groups with fluorine. Moreover, the potential of this method for PET imaging has been demonstrated by the successful 18F labeling of a variety of carboxylic acids with radiochemical conversions up to 50-%, representing a targeted decarboxylative 18F labeling method with no-carrier-added [18F]fluoride. Mechanistic probes suggest that the reaction proceeds through the interaction of the manganese catalyst with iodine(III) carboxylates formed in situ from iodosylbenzene and the carboxylic acid substrates.
