Synthesis and preclinical evaluation of novel PET probes for P-glycoprotein function and expression

P-glycoprotein (P-gp) is an ATP-dependent efflux pump protecting the body against xenobiotics. A P-gp substrate (7) and an inhibitor (6) were labeled with 11C, resulting in potential tracers of P-gp function and expression. Methods: 6 and 7 were labeled using 11CH3I. 11C-verapamil was prepared as published previously, using 11C-methyl triflate. MicroPET scans (with arterial sampling) and biodistribution studies were performed in rats pretreated with saline, cyclosporin A (CsA, 50 mg/kg), or cold 6 (15 mg/kg). Results: The radiochemical yields of 11C-6 and 11C-7 were approximately 30%with a total synthesis time of 45 min. Cerebral distribution volumes (DV) of 11C-6 (2.35 ¡À 0.11) and 11C-7 (1.86 ¡À 0.15) in saline-treated rats were higher than of 11C-verapamil (0.64 ¡À 0.12). DVs of 11C-7 and 11C-verapamil were significantly increased by CsA (to 5.26¡À0.14 and 5.85¡À0.32, respectively). The DV of 11C-6 was reduced by cold 6 (to 1.65¡À0.03). Its uptakewas also reduced (up to 67%) in several peripheral organs that express P-gp. Conclusions: 11C-7 is a novel tracer of P-gp function with higher baseline uptake than 11C-verapamil. Upregulation of P-gp function in response to treatment (which is hard to detect with 11C-verapamil) may be detectable using 11C-7 and PET. Because 11C-6 shows specific binding in target organs, this compound is the first PET tracer allowing measurement of P-gp expression.

Enantioselective oxidative cross-dehydrogenative coupling of tertiary amines to aldehydes

Cooperative catalysts: An enantioselective and direct oxidative coupling of aldehydes to tertiary amines to give beta-amino alcohols is described. Catalyzed by copper(II), the reaction proceeds to give a racemic mixture of products; however, by using a combination of copper(II) and a chiral amine catalyst, the reaction gives the desired products with high enantioselectivity (see scheme).

Activity-lipophilicity relationship studies on P-gp ligands designed as simplified tariquidar bulky fragments

A series of alkyloxyquinoline derivatives has been developed to evaluate the relationship between P-gp potency and lipophilicity. The results show a satisfactory lipophilicity-activity correlation although a series of derivatives showing higher P-gp potency is needed in order to confirm this hypothesis.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1745-07-9 is helpful to your research. Synthetic Route of 1745-07-9

Ring expansion of 1,2,3,4-tetrahydroisoquinolines to dibenzo[c,f]azonines. An unexpected [1,4]-sigmatropic rearrangement of nitrile-stabilized ammonium ylides

When the products of a Strecker reaction of 1,2,3,4-tetrahydroisoquinolines with aromatic aldehydes are quaternized with alkyl triflates and subsequently treated with base, a ring expansion to 6,7,8,13-tetrahydro-5H-dibenzo[c,f] azonine-5-carbonitriles takes place. The nine-membered cyclic products can be obtained in good yields (78-89%) in a process involving the [1,4]-sigmatropic rearrangement of a nitrile-stabilized ammonium ylide. The reaction sequence provides a new, simple, and efficient method for the synthesis of these unusual N-heterocycles.

The formation of the salt and neutral molecule cocrystal from equimolar solution of heliamine and bicyclo[2.2.1]hept-5-ene-endo-2,3-dicarboxylic acid

The possible interaction of 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline (heliamine) with bicyclo[2.2.1]hept-5-ene-endo-2,3-dicarboxylic acid anhydride has been studied. Instead of the reaction with heliamine, the acid anhydride was hydrolyzed into the appropriate dicarboxylic acid. An equimolar mixture of unreacted heliamine and in-situ-generated dicarboxylic acid crystallized in space group P21/c. The comprehensive study of the obtained crystals shows that the peculiarities of the crystallization process lead to the formation of the salt-cocrystal structure where the dianion interacts simultaneously with two cations forming a chain as the primary structural motif. The neutral molecules of dicarboxylic acid link the dianions of the neighbouring chains, forming a layer as the secondary structural motif. As a result, the stronger hydrogen bonds formed by the neutral molecules play a secondary role in the crystal structure formation.

Carbonic anhydrase inhibitors: Design, synthesis and structural characterization of new heteroaryl-N-carbonylbenzenesulfonamides targeting druggable human carbonic anhydrase isoforms

A set of heteroaryl-N-carbonylbenzenesulfonamides has been designed, synthesized, and screened as inhibitors of human carbonic anhydrases (hCAs). The new sulfonamide derivatives were tested against hCA I, hCA II, hCA VII, hCA IX, and hCA XII isoforms using acetazolamide (AAZ, 1) and topiramate (TPM, 2) as reference compounds. Six compounds were low nanomolar inhibitors of tumor-associated hCA IX isoform (Ki values < 10 nM); among them we identified three arylsulfonamides showing unexpected inefficacy over brain distributed hCA VII isoform (hCA IX/hCA VII selectivity ratio > 1500 for compound 5c). Thus, these compounds can offer the opportunity to highlight the interactions preventing the inhibition of hCA VII mainly expressed in central nervous system. Thereby, we used structural and computational techniques to study in depth the interaction with hCAs. In an effort to confirm the inhibitory action we determined crystal structures of five selected heteroaryl-N-carbonylbenzenesulfonamides (4a, 4b, 4e, 5c, and 5e) in complex with hCA II. Moreover, to explore the lack of inhibitory effects of selected compounds (e.g.4b and 5c) we also performed docking studies into hCA VII catalytic site.

A library of spirooxindoles based on a stereoselective three-component coupling reaction

A collection of structurally complex and chemically diverse small molecules is a useful tool to explore cell circuitry. In this article, we report the split-pool synthesis of more than 3000 spirooxindoles on high capacity macrobeads. The key reaction to assemble the spirooxindole core stereoselectively is a Lewis acid variant of the Williams’ three-component coupling. After formation, the skeleton was elaborated using Sonogashira couplings, amide forming reactions, and N-acylations of gamma-lactams. The final library was analyzed by sampling individual macrobeads and by using binomial confidence limits. It was determined that at least 82% of the library compounds should have better than 80% purity. To demonstrate the utility of our discovery process, a high-throughput chemical genetic modifier screen was performed using stock solutions of the resultant products. A number of positives were identified as enhancers of the cellular actions of latrunculin B, an actin polymerization inhibitor. Through resynthesis, we confirmed one of the positives and demonstrated that, in yeast cells, it has an EC50 in the sub-micromolar range.

Novel Benzo[a]quinolizidine Analogs Induce Cancer Cell Death through Paraptosis and Apoptosis

Paraptosis is nonapoptotic cell death characterized by massive endoplasmic reticulum (ER)- or mitochondria-derived vacuoles. Induction of paraptosis offers significant advantages for the treatment of chemotherapy-resistant tumors compared with anticancer drugs that rely on apoptosis. Because some natural alkaloids induce paraptotic cell death, a novel series of benzo[a]quinolizidine derivatives were synthesized, and their antiproliferative activity and ability to induce cytoplasmic vacuolation were analyzed. Structural optimization led to the identification of the potent compound 22b, which inhibited cancer cell proliferation in vitro and in vivo and profoundly facilitated paraptosis-like cell death and induced caspase-dependent apoptosis. Further investigation revealed that 22b-mediated vacuolation originated from persistent ER stress and upregulation of LC3B. Paraptosis induced by benzo[a]quinolizidine derivatives thus represents an alternative strategy for cancer chemotherapy.
