Investigating isoindoline, tetrahydroisoquinoline, and tetrahydrobenzazepine scaffolds for their sigma receptor binding properties

Substituted norbenzomorphans are known to display high affinity and selectivity for the two sigma receptor (sigmaR) subtypes. In order to study the effects of simplifying the structures of these compounds, a scaffold hopping strategy was used to design several novel sets of substituted isoindolines, tetrahydroisoquinolines and tetrahydro-2-benzazepines. The binding affinities of these new compounds for the sigma 1 (sigma1R) and sigma 2 (sigma2R) receptors were determined, and some analogs were identified that exhibit high affinity (Ki ? 25 nM) and significant selectivity (>10-fold) for sigma1R or sigma2R. The preferred binding modes of selected compounds for the sigma1R are predicted by modeling studies, and the nature of substituents on the aromatic ring and the nitrogen atom of the bicyclic skeleton appears to affect the preferred binding orientation of sigma1R-preferring ligands.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 226942-29-6, and how the biochemistry of the body works.Application of 226942-29-6

Metal-Free Dehydrogenation of N-Heterocycles by Ternary h-BCN Nanosheets with Visible Light

An efficient metal-free catalytic system has been developed based on hexagonal boron carbon nitride (h-BCN) nanosheets for the dehydrogenation of N-heterocycles with visible light; hydrogen gas is released in the process, and thus no proton acceptor is needed. This acceptorless dehydrogenation of hydroquinolines, hydroisoquinolines, and indolines to the corresponding aromatic N-heterocycles occurred in excellent yield under visible-light irradiation at ambient temperature. With h-BCN as the photocatalyst and water as the solvent, this environmentally benign protocol shows broad substitution tolerance and high efficiency.

Synthesis Of Biologically Active Bis(Indolyl)Methane Derivatives by Bisindole Alkylation of Tetrahydroisoquinolines with Visible-Light Induced Ring-Opening Fragmentation

A visible-light photoredox catalyzed ring-opening functionalization of tetrahydroisoquinolines with bisindole alkylation has been developed, which expedites a new vista for the synthesis of bis(indolyl)methane derivatives. The transformation comprises a series of cascade reactions, photoredox catalysis, amine oxidation, fragmentation and Friedel?Craft alkylation. Five of the prepared bis(indolyl)methane derivatives containing the para substitution group on the side chain of benzene suppressed cancer cell growth in human breast adenocarcinoma MDA-MB-231 cells, and one candidate demonstrated a significant effect on cell migration.

Photoredox-Controlled Mono- and Di-Multifluoroarylation of C(sp3)?H Bonds with Aryl Fluorides

A controllable mono- and di-multifluoroarylation of acyclic and cyclic N-aryl amines with aryl fluorides by photocatalyzed dual C(sp3)?H/C(sp2)?F functionalization has been developed, providing new access to a wide array of valuable alpha-fluoroarylated amines. In addition, the one-pot consecutive hetero-di-multifluoroarylation of N-aryl pyrrolidines and N,N-dimethylanilines was achieved with high to excellent diastereoselectivity. This new defluorinative C(sp3)?C(sp2) coupling is distinguished by a broad scope, good regioselectivity, and mild conditions as well as gram-scale and late-stage applicability, and thus constitutes a significant advance in the arylation of unactivated C(sp3)?H bonds with aryl fluorides.

Triazolinone Biphenylsulfonamide Derivatives as Orally Active Angiotensin II Antagonists with Potent AT1 Receptor Affinity and Enhanced AT2 Affinity

Several series of 2,4-dihydro-2,4,5-trisubstituted-3H-1,2,4-triazol-3-ones with acidic sulfonamide replacements of tetrazole at the 2′-position of the biphenyl-4-ylmethyl side chain at N4 were prepared and tested as angiotensin II (AII) antagonists.Preferred substituents on the triazolinone ring were n-butyl at C5 and 2-(trifluoromethyl)phenyl at N2.Subnanomolar IC50 values at the AT1 receptor subtype were observed for a variety of acylsulfonamides, including aroyl, heteroaroyl, and cycloalkylcarbonyl derivatives.Certain other acidic sulfonamides, such as sulfonylcarbamates and disulfimides also displayed high affinity for the AT1 receptor.In addition, AT2 binding for some of these compounds was increased by as much as 1000-fold over the corresponding tetrazole (e.g., AT2 IC50 17 nM for the tert-butyl sulfonylcarbamate 92).When evaluated for inhibition of the AII pressor response, the benchmark benzoylsulfonamide 9 (L-159,913) was efficacious in several species and was superior to losartan (1a) in conscious rhesus monkeys.Several subsequent analogues, including the 2-chlorobenzoyl (18), (3-chlorothiophene-2-yl)carbonyl (51), ((S)-2,2-dimethylcyclopropyl)carbonyl (80), and tert-butoxycarbonyl (92) derivatives, were highly effective in rats, surpassing 9 and losartan in duration of action and/or potency.Compound 18 (L-162,223) displayed very prolonged AII antagonism in the rat model (>24 h at 1 mg/kg iv).At 1 mg/kg po in rats, 18 and 92 (L-162,234) produced 85-87percent peak inhibition of the AII pressor response with duration exceeding 6 h.The identification of triazolinone-based sulfonamide derivatives combining high AT1 affinity, considerably enhanced AT2 potency, and favorable in vivo properties provides insights relevant to the design of dual AT1/AT2 receptor antagonists.

Development of highly potent inhibitors of Ras farnesyltransferase possessing cellular and in vivo activity

Analogs of CVFM (a known nonsubstrate farnesyltransferase (FT) inhibitor derived from a CA2A2X sequence where C is cysteine, A is an aliphatic residue, and X is any residue) were prepared where phenylalanine was replaced by (Z)-dehydrophenylalanine, 2-aminoindan-2-carboxylate, 1,2,3,4- tetrahydroisoquinoline-3-carboxylate (Tic), and indoline-2-carboxylate. The greatest improvement in FT inhibitory potency was observed for the Tic derivative (IC50 = 1 nM); however, this compound was ineffective in blocking oncogenic Ras-induced transformation of NIH-3T3 fibroblast cells. A compound was prepared in which both the Cys-Val methyleneamine isostere and the Tic replacement were incorporated. This derivative inhibited FT with an IC50 of 0.6 nM and inhibited anchorage-independent growth of stably transformed NIH-3T3 fibroblast cells by 50% at 5 muM. Replacing the A1 side chain of this derivative with a tert-butyl group and replacing the X position with glutamine led to a derivative with an IC50 of 2.8 nM and an EC50 of 0.19 muM, a 26-fold improvement(S*,R*)-N-[[2-[N-(2-amino-3- mercaptopropyl)-L-valyl]-1,2,3,4-tetrahydro-3-isoquinolinyl]carbonyl]-L- methionine. This derivative, (S*,R*)-N-[[2-[N-(2-amino-3-mercaptopropyl)- L-tert-leucyl]-1,2,3,4-tetrahydro-3-isoquinolinyl]-carbonyl]-L-glutamine, was evaluated in vivo along with (S*,R*)-N-[[2-[N-(2-amino-3-mercaptopropyl)- L-tert-leucyl]-1,2,3,4-tetrahydro-3-isoquinolinyl]carbonyl]-L-methionine methyl ester for antitumor activity in an athymic mouse model implanted ip with H-ras-transformed rat-1 tumor cells. When administered by injection twice a day at 45 mg/kg for 11 consecutive days, both compounds showed prolonged survival time (T/C = 142-145%), thus demonstrating efficacy against ras oncogene-containing tumors in vivo.
