18F-Labeled indole-based analogs as highly selective radioligands for imaging sigma-2 receptors in the brain

We have designed and synthesized a series of indole-based sigma2 receptor ligands containing 5,6-dimethoxyisoindoline or 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline as pharmacophore. In vitro competition binding assays showed that all ten ligands possessed low nanomolar affinity (Ki?=?1.79?5.23?nM) for sigma2 receptors and high subtype selectivity (Ki (sigma2)/Ki (sigma1)?=?56?708). Moreover, they showed high selectivity for sigma2 receptor over the vesicular acetylcholine transporter (>1000-fold). The corresponding radiotracers [18F]16 and [18F]21 were prepared by an efficient one-pot, two-step reaction sequence with a home-made automated synthesis module, with 10?15% radiochemical yield and radiochemical purity of >99%. Both radiotracers showed high brain uptake and sigma2 receptor binding specificity in mice.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. SDS of cas: 1745-07-9, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1745-07-9, in my other articles.

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.

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.

Benzylic functionalization of (eta6-alkylarene)chromium tricarbonyl complexes

A general method for the regioselective benzylic metallation of (eta6-alkylarene)chromium tricarbonyl complexes on the action of lithium amides in THF under very mild conditions has been developed. Transmetallation reactions of the lithium derivatives thus obtained produce the corresponding benzylic organotin, zinc and copper chromium tricarbonyl complexes. Methods for the preparative benzylic functionalization of (eta6-alkylarene)chromium tricarbonyl complexes have been developed, including carboxylation, alpha-hydroxyalkylation, gamma-carbonylation, acylation, arylation, vinylation, heteroarylation and alkylation procedures. 5-Acetoxy-3-benzyl-1,4-methano-2,3,4,5-tetrahydro-1H-3-benzazepine has been prepared using the benzylic lithium derivative of the (eta6-alkylarene)chromium tricarbonyl complex at the key step.

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.

Alkaloid constituents from flower buds and leaves of sacred lotus (Nelumbo nucifera, Nymphaeaceae) with melanogenesis inhibitory activity in B16 melanoma cells

Methanolic extracts from the flower buds and leaves of sacred lotus (Nelumbo nucifera, Nymphaeaceae) were found to show inhibitory effects on melanogenesis in theophylline-stimulated murine B16 melanoma 4A5 cells. From the methanolic extracts, a new alkaloid, N-methylasimilobine N-oxide, was isolated together with eleven benzylisoquinoline alkaloids. The absolute stereostructure of the new alkaloid was determined from chemical and physicochemical evidence. Among the constituents isolated, nuciferine, N-methylasimilobine, (-)-lirinidine, and 2-hydroxy-1-methoxy-6a,7-dehydroaporphine showed potent inhibition of melanogenesis. Comparison of the inhibitory activities of synthetic related alkaloids facilitated characterization of the structure-activity relationships of aporphine- and benzylisoquinoline-type alkaloids. In addition, 3-30 muM nuciferine and N-methylasimilobine inhibited the expression of tyrosinase mRNA, 3-30 muM N-methylasimilobine inhibited the expression of TRP-1 mRNA, and 10-30 muM nuciferine inhibited the expression of TRP-2 mRNA.
