Multidrug resistance in cancer is a major cause of failure in cancer chemotherapy. In search of new compounds with strong reversal activity and simple molecular structure, we have synthesized a series of compounds in which different substituents were linked to the 2-position of the 6,7-dimethoxy-1-(3, 4-dimethoxybenzyl)-tetrahydroisoquinoline system. Compounds were analyzed for their cytotoxicity by MTT in K562 cell line in vitro, all of the derivatives exhibited little cytotoxic activity. In the meantime, these compounds were evaluated by MTT in K562/A02 cell line in vitro, 6e, 6h and 7c exhibited similar or more potent activities than verapamil with the IC50 values at 0.66, 0.65 and 0.96muM, and with the ratio factor of 24.13, 24.50 and 16.59, respectively.

DMA new set of cyclooxygenase (COX) inhibitors endowed with an additional functionality was explored. These new compounds also contained either rhodamine 6G or 6,7-dimethoxy- 1,2,3,4-tetrahydroisoquinoline, two moieties typical of efflux pump substrates and inhibitors, respectively. Among all the synthesized compounds, two new COX inhibitors with opposite selectivity were discovered: compound 8 [N-(9-{2-[(4-{2-[3- (5-chlorofuran-2-yl)-4-phenylisoxazol-5-yl]acetamido}butyl)carbamoyl] phenyl-6-(ethylamino)-2,7-dimethyl-3H-xanthen-3-ylidene} ethanaminium chloride] was found to be a selective COX- 1 inhibitor, whereas 17 (2-[3,4-bis(4-methoxyphenyl)isoxazol-5- yl]-1-[6,7-dimethoxy-3,4-dihydroisoquinolin-2-(1H)-yl]ethanone) was found to be a sub-micromolar selective COX-2 inhibitor. However, both were shown to interact with P-glycoprotein. Docking experiments helped to clarify the molecular aspects of the observed COX selectivity.

Healthcare careers for chemists are once again largely based in laboratories, although increasingly there is opportunity to work at the point of care, helping with patient investigation. An article , which mentions Quality Control of (S)-1,2,3,4-Tetrahydroisoquinoline-1-carboxylic acid, molecular formula is C10H11NO2., Quality Control of (S)-1,2,3,4-Tetrahydroisoquinoline-1-carboxylic acid

Conformational and biological analysis of the linear 4-11 fragment analogues, Ac--alpha-MSH4-11-NH2 (II) and Ac--alpha-MSH4-11-NH2 (III) and related analogues have been undertaken.In solution, the peptide backbone is flexible, but in the case of D-Phe7 analogues an interaction of the His6.D-Phe7 and Arg8 amino acid side chain groups may be present based on the shielding patterns observed in the proton NMR and on comparison of NT1 values.The importance of the position 7 to the biological and conformational properties was further examined by substitution of either L- or D-phenylglycine (Pgl) or L- and D-1,2,3,4-tetrahydroisoquinoline carboxylic acid (Tic) for phenylalanine-7.Ac--alpha-MSH4-11-NH2 (IV), Ac--alpha-MSH4-11-NH2 (V), Ac--alpha-MSH4-11-NH2 (VI), and Ac--alpha-MSH4-11-MH2 (VII) were prepared.These substituted analogues were examined for their biological activities and conformational properties with emphasis on the three-dimensional orientation of the aromatic ring in the position 7, and the effects of the aromatic ring on adjacent amino acids and on biological activities.The relative potencies of the analogues in the frog skin assay system were: II (1.00); III (118); IV (82.4); V (0.18); VI (0.18); and VII (0.14); and in the lizard skin bioassay they were: II (1.00); III (10.0); IV (0.14); V (0.005); VI (0.00025); and VII (0.01).On the basis of the NMR studies the L-phenylglycine substitution results in an enhanced ring stacking interaction between the phenyl ring of Pgl7 and the indole ring of Trp9.The 1,2,3,4-tetrahydroisoquinoline carboxylic acid (Tic) substitution leads to significant backbone restriction and an interaction of the alpha proton of His6 with the carbonyl of Glu5.The possible relationships of these effects to biological activity are discussed.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 151004-92-1.

A small library of coumarins, carrying butynyl-amino chains, was synthesized continuing our studies in the field of MDR reverting ageEnts and in order to obtain multipotent agents to combat malignancies. In particular, the reported anticancer and chemopreventive natural product 7-isopentenyloxycoumarin was linked to different terminal amines, selected on the basis of our previously reported results. The anticancer behaviour and the MDR reverting ability of the new compounds were evaluated on human colon cancer cells, particularly prone to develop the MDR phenotype. Some of the new derivatives showed promising effects, directly acting as cytotoxic compounds and/or counteracting MDR phenomenon. Compound 1e emerged as the most interesting of this series, showing a multipotent biological profile and suggesting that conjugation of an appropriate coumarin core with a properly selected butynyl-amino chain allows to obtain novel hybrid molecules endowed with improved in vitro antitumor activity.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 1745-07-9 is helpful to your research. Safety of 6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline

Conjugate addition reactions of sulfur-stabilized nucleophiles to the delta-lactam unit of tetrahydrobenzo[a]benzoquinolizines have been studied. The stereochemical outcome of the conjugate addition reaction depends on the nature of the substituent at the angular position, thus 2,11b-cis or 2,11b-trans diastereomers could be obtained selectively. The tandem conjugate addition-alkylation also takes place in good yields and with high diastereoselectivity. The polyfunctionalized hexahydrobenzo[a]quinolizinone systems obtained could be further elaborated toward emetine-like structures.

A practical protocol has been developed here for the Mn(II)-catalyzed N -acylation of amines with high yields using N, N -dimethylformamide and other amides as the carbonyl source. The protocol is simple, does not require any acid, base, ligand, or other additives, and encompasses a broad substrate scope for primary, secondary, and heterocyclic amines.

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.Application In Synthesis of 7-Nitro-1,2,3,4-tetrahydroisoquinoline, you can also check out more blogs about42923-79-5

P-glycoprotein (P-gp) is an ATP-dependent efflux pump protecting the body against xenobiotics. The in vitro characterized modulator 6,7-dimethoxy-2-(6- methoxy-naphthalen-2-ylmethyl)-1,2,3,4-tetrahydroisoquinoline (MC80) of the P-gp pump was labelled with 11C and evaluated in vivo for its potential to image P-gp function and expression. Radiochemical pure (>98%) [ 11C]MC80 was obtained within 25 min starting from [ 11C]methyl iodide with radiochemical yield of 26%. Biodistribution studies in FVB mice demonstrated a high baseline brain uptake (7.66 ± 1.38%ID/g at 1 min pi). Cerebral uptake was increased in mdr1a knock-out mice as well as after CsA pretreatment. Pre-administration of an excess of non-radioactive MC80 caused a reduced uptake in several target organs including brain, pancreas and intestines. The results indicate that [11C]MC80 kinetics are modulated by P-gp. Reversed phase-HPLC analysis of brain revealed an excellent metabolic profile (>90% intact [11C]MC80).

YEATS domain (YD) containing proteins are an emerging class of epigenetic targets in drug discovery. Dysregulation of these modified lysine-binding proteins has been linked to the onset and progression of cancers. We herein report the discovery and characterisation of the first small-molecule chemical probe, SGC-iMLLT, for the YD of MLLT1 (ENL/YEATS1) and MLLT3 (AF9/YEATS3). SGC-iMLLT is a potent and selective inhibitor of MLLT1/3?histone interactions. Excellent selectivity over other human YD proteins (YEATS2/4) and bromodomains was observed. Furthermore, our probe displays cellular target engagement of MLLT1 and MLLT3. The first small-molecule X-ray co-crystal structures with the MLLT1 YD are also reported. This first-in-class probe molecule can be used to understand MLLT1/3-associated biology and the therapeutic potential of small-molecule YD inhibitors.

The target-guided, in situ click chemistry approach to lead discovery has been successfully employed for discovering acetylcholinesterase (AChE) inhibitors by incubating a selected enzyme/tacrine azide combination with a variety of acetylene reagents that were not previously known to interact with the enzyme’s peripheral binding site. The triazole products, formed by the enzyme, were identified by HPLC-mass spectrometry analysis of the crude reaction mixtures. The target-guided lead discovery search was also successful when performed with reagent mixtures containing up to 10 components. From 23 acetylene reagents, the enzyme selected two phenyltetrahydroisoquinoline (PIQ) building blocks that combined with the tacrine azide within the active center gorge to form multivalent inhibitors that simultaneously associate with the active and peripheral binding sites. These new inhibitors are up to 3 times as potent as our previous phenylphenanthridinium-derived compounds, and with dissociation constants as low as 33 femtomolar, they are the most potent noncovalent AChE inhibitors known. In addition, the new compounds lack a permanent positive charge and aniline groups and possess fewer fused aromatic rings. Remarkably, despite the high binding affinity, the enzyme displayed a surprisingly low preference for one PIQ enantiomer over the other.
