Flavones Inhibit the Activity of AKR1B10, a Promising Therapeutic Target for Cancer Treatment

AKR1B10 is an NADPH-dependent reductase that plays an important function in several physiological reactions such as the conversion of retinal to retinol, reduction of isoprenyl aldehydes, and biotransformation of procarcinogens and drugs. A growing body of evidence points to the important role of the enzyme in the development of several types of cancer (e.g., breast, hepatocellular), in which it is highly overexpressed. AKR1B10 is regarded as a therapeutic target for the treatment of these diseases, and potent and specific inhibitors may be promising therapeutic agents. Several inhibitors of AKR1B10 have been described, but the area of natural plant products has been investigated sparingly. In the present study almost 40 diverse phenolic compounds and alkaloids were examined for their ability to inhibit the recombinant AKR1B10 enzyme. The most potent inhibitors-apigenin, luteolin, and 7-hydroxyflavone-were further characterized in terms of IC50, selectivity, and mode of action. Molecular docking studies were also conducted, which identified putative binding residues important for the interaction. In addition, cellular studies demonstrated a significant inhibition of the AKR1B10-mediated reduction of daunorubicin in intact cells by these inhibitors without a considerable cytotoxic effect. Although these compounds are moderately potent and selective inhibitors of AKR1B10, they constitute a new structural type of AKR1B10 inhibitor and may serve as a template for the development of better inhibitors.

A novel universal linker for efficient synthesis of phosphorothioate oligonucleotides

A versatile and conformationally preorganized universal linker molecule is reported here for efficient synthesis of phosphorothioate oligonucleotides. With respect to nucleoside loaded support, comparable yield and quality based on ion-pair LC-MS are obtained for both deoxy and 2?-O-methoxyethyl modified phosphorothioate oligonucleotides. No 3?-phosphate or phosphorothioate monoester or any modification of universal molecule still attached to oligonucleotide was observed.

Enantioselective Pd-catalyzed alpha-arylation of N-Boc-pyrrolidine: The key to an efficient and practical synthesis of a glucokinase activator

(Chemical Equation Presented) A short and practical synthesis of glucokinase activator 1 was achieved utilizing a convergent strategy involving SNAr coupling of activated aryl fluoride 11 with hydroxypyridine 9. The key to the success of the synthesis was the development of a novel method for enantioselective formation of alpha-arylpyrrolidines during the course of the project. In this method, (-)-sparteine-mediated enantioselective lithiation of N-Boc-pyrrolidine was followed by in situ transmetalation to zinc and Pd-catalyzed coupling with aryl bromide 3, proceeding in 92% ee. This transformation allowed the preparation of compound 1 in a 31% overall yield over six steps.

Structure-activity relationship studies of lipophilic teicoplanin pseudoaglycon derivatives as new anti-influenza virus agents

Six series of semisynthetic lipophilic glycopeptide antibiotic derivatives were evaluated for in vitro activity against influenza A and B viruses. The new teicoplanin pseudoaglycon-derived lipoglycopeptides were prepared by coupling one or two side chains to the N-terminus of the glycopeptide core, using various conjugation methods. Three series of derivatives bearing two lipophilic groups were synthesized by attaching bis-alkylthio maleimides directly or through linkers of different lengths to the glycopeptide. Access to the fourth and fifth series of compounds was achieved by click chemistry, introducing single alkyl/aryl chains directly or through a tetraethylene glycol linker to the same position. A sixth group of semisynthetic derivatives was obtained by sulfonylation of the N-terminus. Of the 42 lipophilic teicoplanin pseudoaglycon derivatives tested, about half showed broad activity against influenza A and B viruses, with some of them having reasonable or no cytotoxicity. Minor differences in the side chain length as well as lipophilicity appeared to have significant impact on antiviral activity and cytotoxicity. Several lipoglycopeptides were also found to be active against human coronavirus.

Recent developments in cholinesterases inhibitors for Alzheimer’s disease treatment

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder of the central nervous system (CNS) which is the most common cause of dementia in the elderly. It is characterized by the deficits in the cholinergic system and presence of characteristic hallmarks: neurofibrillary tangles and amyloid plaques. Since the cholinergic system plats an important role in the regulation of learning and memory processes it became a target for the design of antialzheimer drugs. Cholinesterase inhibitors enhance cholinergic transmission indirectly, by inhibiting the enzyme which hydrolyses acetylcholine. It has been also demonstrated that acetylcholinesterase (AChE) is involved in the development of amyloid plaques. Therefore, substances which are AChE inhibitors (AChEI) are the only drugs approved for the symptomatic treatment of AD. This review presents the main classes of cholinesterase inhibitors developed recently for the treatment of AD. We hace started with the analogues of the existing drugs: tacrine, donepezil, rivastigmine and galantamine which are still of interest for many research groups. Among them there is a very interesting group – dual binding site inhibitors characterized by increased inhibitory potency against AChE and amyloid plaques formation. There is also a group of compounds with additional properties such as: antioxidant activity, affinity to 5-IIT3 receptors, inhibition of N-methyltransferase that metabolize histamine, which can be beneficial for the treatment of AD. Furthermore there are some interesting compounds which belong to different chemical groups also of natural origin. In this review we sum up current research concerned with development of AChEIs which can be more effective in the future treatment of AD.

Formal intermolecular [2 + 2] cycloaddition reaction of alleneamides with alkenes via gold catalysis

An efficient method was developed to construct the densely functionalized cyclobuane adducts through formal intermolecular cycloaddition of alleneamides with electron-rich olefins via gold catalysis, in which vinyl ethers/amides and electron-rich styrenes worked very well. In addition, a series of alleneamide dimerization products were prepared from the same alleneamide substrates.

P-chirogenic silylphosphine-boranes: Synthesis and phospha-Michael reactions

Chiral and achiral silylphosphine-boranes were prepared in high yields by reaction of phosphide boranes with halogenosilanes. Their reaction at room temperature with Michael acceptors afforded 1,4-addition products as silylenol ether or ketone derivatives in good to excellent yields. In the case of the 2,3-dihalogeno-maleimides, the double addition of silylphosphine-borane led to the corresponding trans-diphosphine-boranes in 86% yield. Noteworthy, the reaction of Pchirogenic silylphosphine-boranes with enones afforded the phospha-Michael adducts without racemization at the P-center. While the silylphosphine-boranes have been scarcely described so far, these compounds demonstrate their great interest for the synthesis of chiral and achiral functionalized organophosphorus compounds.
