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.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. HPLC of Formula: C11H13NO2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 3382-18-1, in my other articles.

Analogues of the potent alpha2-adrenoceptor antagonist (8aR,12aS,13aS)-5,8,8a,9,10,11,12,12a,13,13a-decahydro-3-methoxy-12- (methylsulfonyl)-6H-isoquino[2,1-g][1,6]naphthyridine (1b) were prepared and evaluated for alpha1- and alpha2-adrenoceptor affinity. Affinity for alpha2-adrenoceptors was assessed by displacement of [3H]yohimbine from rat cerebral cortical membranes and although 1b and close structural analogues demonstrated high affinity, none were selective for the alpha(2A) or alpha(2B) subtypes reputedly present in this tissue. All of the high affinity alpha2-adrenoceptor ligands were, however, selective with respect to [3H]prazosin (alpha1) binding. Affinity for [3H]yohimbine-labeled alpha2-adrenoceptors was found to be highly dependent on the stereochemistry of the tetracyclic system. The 8abeta,12aalpha,13aalpha diastereomer of 1 (56) had moderate affinity for alpha2-adrenoceptors while the 8abeta,12abeta,13aalpha diastereomer (55) had very low affinity. The affinity and selectivity of these agents for alpha2-adrenoceptors was found to correspond to that observed for several isomeric yohimbine analogues which have similar relative and absolute stereochemistries. Deviation from the structure of 1 by opening the B ring, changing the position of the sulfonamide nitrogen, or changing the attachment of the D ring led to a dramatic decrease in alpha2-adrenoceptor affinity. High binding affinity was found to correlate with functional antagonism in the guinea pig ileum. The reversal of clonidine-induced mydriasis in the rat was used to assess bioavailability and indicated that 1b was a potent alpha2-adrenoceptor antagonist in vivo.

(R)-(+)-8,9-Dimethoxy-6,10b-dihydro-5H-thiazolo[2,3-a]isoquinolin-3-one 1 has been synthesized from 6,7-dimethoxy-3,4-dihydroisoquinoline and menthyl thioglycolate. Compound 1 was obtained in the enantiomerically pure form (mp 150-153C, [alpha]D +436) by a single crystallization of the crude reaction product (68% e.e.) from 96% ethanol. The absolute 10bR configuration was established by X-ray diffraction. Oxone oxidation of 1 resulted in a configurationally unstable dextrorotatory syn-sulfoxide 2 (mp 173-175C, [alpha]D +62.8).

A modular aerobic oxidation of amines to imines has been achieved using an ortho-naphthoquinone (o-NQ) catalyst. The cooperative catalyst system of o-NQ and Cu(OAc)2 enabled the formation of homocoupled imines from benzylamines, while the presence of TFA helped the formation of cross-coupled imines in excellent yields. The current mild aerobic oxidation protocol could also be applied to the oxidation of secondary amines to imines or ketimines with the help of cocatalyst, Ag2CO3, with excellent yields.

We have developed an efficient synthesis of indole fused aminals with nucleophilic imines and indole-derived alpha,alpha-dicyanoolefins via N -sulfonyl group transfer. The combination of two privileged frameworks, tetrahydroisoquinoline or tetrahydro-beta-carboline and indole, can be realized by this approach to the construction of aminals. The synthetic application of this method was further demonstrated by the straightforward transformations into highly functionalized aminals possessing carbonyl groups through oxidative cleavage of the nitrile moiety.

(Chemical Equation Presented) Detailed mechanistic studies on our recently reported asymmetric addition reactions of malonates to dihydroisoquinolines (DHIQs) catalyzed by chiral Pd(II) complexes were carried out. It was found that an N,O-acetal was generated in situ by the reaction of DHIQ with (Boc) 2O, and cooperative action of the Pd(II) complex as an acid-base catalyst allowed the formation of a chiral Pd enolate and a reactive iminium ion via alpha-fragmentation. The iminium ion was also accessible via oxidation with DDQ as an oxidant, and a catalytic asymmetric oxidative Mannich-type reaction was achieved with tetrahydroisoquinolines (THIQs) as starting materials. This oxidation protocol was applicable to N-acryloyl-protected THIQs, allowing the efficient synthesis of optically active tetrahydrobenzo[a] quinolizidine derivatives via intramolecular Michael reaction.

The addition of the lithium carbanion of methyl phenyl sulfoxide and (R)-(+)-methyl p-tolyl sulfoxide to imines having at least one aryl substituent, under kinetically controlled conditions, gives beta-amino sulfoxides with good to modest diastereoselection.Under equilibrium controlled condition poor product diastereoselection results.The addition of these anions to 3,4-dihydro-6,7-dimethoxyisoquinoline is unique in that the most favorable product diastereoselection (92:8) is observed under equilibrium controlled conditions.Deuteration experiments suggest that equilibration occurs via a beta-amino alpha-lithio sulfinyl carbanion through a retro-Michael addition then Michael addition reaction sequence.This methodology allows for the construction of (R)-(+)-tetrahydropalmatine in four efficient synthetic steps.
