Three-Component Coupling Involving Arynes, Aromatic Tertiary Amines, and Aldehydes via Aryl-Aryl Amino Group Migration

The transition-metal-free multicomponent coupling of arynes, aromatic tertiary amines, and aldehydes proceeding via the aryl to aryl amino group migration has been demonstrated. This protocol allows rapid access to ortho-functionalized tertiary amines in moderate to good yields. Moreover, activated ketones can also be used as the aldehyde component in the present reaction. The similarity of the aryl-aryl tertiary amino group migration with the Smiles rearrangement is striking.

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.Recommanded Product: 3340-78-1, you can also check out more blogs about3340-78-1

In vitro activity of novel dual action MDR anthranilamide modulators with inhibitory activity at CYP-450

Synthesis and in vitro cytotoxicity assays of new anthranilamide MDR modulators have been performed to assess their inhibition potency of the P-glycoprotein (P-gp) transporter. The aromatic spacer group between nitrogen atoms (N1 and N2) in the known inhibitor XR9576 was replaced with a flexible alkyl chain of 2 to 6 carbon atoms in length. 6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline and their open-chain N-methylhomoveratrylamine counterparts were shown to be potent P-gp inhibitors. The maximal inhibition was obtained when using an ethyl or propyl spacer. Several compounds were more potent than verapamil and intrinsically less cytotoxic than XR9576. In addition, in vitro metabolism studies of 23a with a subset of human CYP-450 isoforms revealed that, unlike XR9576, 23a inhibited CYP3A4, an enzyme that colocalizes with P-gp in the intestine and contributes to tumor cell chemoresistance by enhancing the biodisposition of anticancer drugs such as paclitaxel toward metabolism. In this context, 22a might be a suitable candidate for further drug development.

Photocatalytic deaminative benzylation and alkylation of tetrahydroisoquinolines with N-alkylpyrydinium salts

A ruthenium-catalyzed photoredox coupling of substituted N-aryltetrahydroisoquinolines (THIQs) and different bench-stable pyridinium salts was successfully developed to give fast access to 1-benzyl-THIQs. Furthermore, secondary alkyl and allyl groups were also successfully introduced via the same method. Additionally, the typically applied N-phenyl group in the THIQ substrate could be replaced by the cleavable p-methoxyphenyl (PMP) group and successful N-deprotection was demonstrated.

An LP1 analogue, selective MOR agonist with a peculiar pharmacological profile, used to scrutiny the ligand binding domain

The hypothesis that central analgesia with reduced side effects is obtainable by occupying an ?allosteric? site in the MOR ligand binding domain requires the development of new ligands with peculiar pharmacological profile to be used as tools. New benzomorphan derivatives, analogues of LP1, a multitarget MOR agonist/DOR antagonist, were designed to examine in depth MOR ligand binding domain. Compound 5, bearing a diphenylic N-substituent on the benzomorphan nucleus, showed an affinity (Kimu = 0.5 ± 0.2 nM) comparable to that of LP1 and a better selectivity versus DOR and KOR. It elicits antinociceptive effects in ex vivo (GPI) and in vivo. This new compound engages receptor amino acidic residues not reached by LP1 and by other established MOR ligands. Molecular modeling studies, conducted on 5 and on several reference compounds, allowed us to propose possible residues in the MOR ligand binding domain essential for their interactions with ?orthosteric? and ?allosteric? binding sites.

Construction of 1,3-Oxazolidines through a Three-Component [3+2] Cycloaddition of Tetrahydroisoquinolines, Aldehydes, and Ethyl Ketomalonate

A chemoselective and diastereoselective synthesis of fused oxazolidines was achieved by a three-component cascade reaction of tetrahydroisoquinolines (THIQs), alpha,beta-unsaturated aldehydes, and diethyl 2-oxomalonate. Probably due to the reactivity difference between the aldehyde and the ketone, the reaction proceeded through the condensation of THIQs with alpha,beta-unsaturated aldehydes and 1,3-dipolar cycloaddition of the generated azomethine ylide intermediate with 2-oxomalonate. The key features are easily available starting materials, mild reaction conditions, broad substrate scope, and high chemo- and diastereoselectivity.

Structure?Activity Relationship Studies on (R)-PFI-2 Analogues as Inhibitors of Histone Lysine Methyltransferase SETD7

SETD7 is a histone H3K4 lysine methyltransferase involved in human gene regulation. Aberrant expression of SETD7 has been associated with various diseases, including cancer. Therefore, SETD7 is considered a good target for the development of new epigenetic drugs. To date, few selective small-molecule inhibitors have been reported that target SETD7, the most potent being (R)-PFI-2. Herein we report structure?activity relationship studies on (R)-PFI-2 and its analogues. A library of 29 structural analogues of (R)-PFI-2 was synthesized and evaluated for inhibition of recombinantly expressed human SETD7. The key interactions were found to be a salt bridge and a hydrogen bond formed between (R)-PFI-2?s NH2+ group and SETD7?s Asp256 and His252 residue, respectively.

Search for New Alkaloids in Pachycereus weberi by Tandem Mass Spectrometry

Twenty new alkaloids, of which 13 are new natural products, have been discovered in Pachycereus weberi by tandem mass spectrometry using a mass-analyzed ion kinetic energy spectrometer.These observations have been confirmed by chromatography and, in many cases, by simple synthetic interconversions from known alkaloids.Particularly significant is the discovery of several alkaloids having the same molecular formula.Isomer distinctions such as these, which are difficult to make on pure compounds by mass spectrometry, were made by utilizing daughter spectra recorded succesively during the evaporation of the material from the probe and/or from spectra recorded on different types of plant extracts.This study suggests that many natural materials may contain trace amounts of compounds of potential biomedical or synthetic interest and, in particular, that the number of known alkaloids might be greatly increased by experiments of this type.
