We report herein the synthesis of new dioxopiperazine isoquinolines using the Pictet-Spengler cyclisation. Our synthetic strategy for the preparation of two new compounds (5, 6), with a tetrahydro-6H-pyrazino[1,2-b]isoquinoline-1,4-dione moiety was developed in only four steps. To understand better the crucial step of the synthesis reported here, theoretical calculations using semiempirical (PM3), ab initio and DFT computations were carried out on a reduced system model. The structure of chlorohydrate water solvate of tetrahydro (2-piperidinylethyl)-6H-pyrazino [1,2-b]isoquinoline-1,4-dione (6·HCl·2H2O) was determined by X-ray diffraction. Theoretical calculations (RHF/3-21G and RB3LYP/6-31G(d)) were also performed for compound 6 neutralised with a chloride ion.

A series of novel 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid derivatives were designed, synthesized and assayed for their activities against aminopeptidase N (APN/CD13) and MMP-2. The results showed that most compounds exhibited higher inhibitory activities against APN than that of MMP-2. Within this series, compound 12h (IC50 = 6.28 ¡À 0.11 muM) showed similar inhibitory activities compared with Bestatin (IC50 = 5.55 ¡À 0.01 muM), and it could be used as novel lead compound for the future APN inhibitors development as anticancer agents.

Discovery of Tetrahydroisoquinoline-Containing CXCR4 Antagonists with Improved in Vitro ADMET Properties

CXCR4 is a seven-transmembrane receptor expressed by hematopoietic stem cells and progeny, as well as by ?48 different cancers types. CXCL12, the only chemokine ligand of CXCR4, is secreted within the tumor microenvironment, providing sanctuary for CXCR4+ tumor cells from immune surveillance and chemotherapeutic elimination by (1) stimulating prosurvival signaling and (2) recruiting CXCR4+ immunosuppressive leukocytes. Additionally, distant CXCL12-rich niches attract and support CXCR4+ metastatic growths. Accordingly, CXCR4 antagonists can potentially obstruct CXCR4-mediated prosurvival signaling, recondition the CXCR4+ leukocyte infiltrate from immunosuppressive to immunoreactive, and inhibit CXCR4+ cancer cell metastasis. Current small molecule CXCR4 antagonists suffer from poor oral bioavailability and off-target liabilities. Herein, we report a series of novel tetrahydroisoquinoline-containing CXCR4 antagonists designed to improve intestinal absorption and off-target profiles. Structure-activity relationships regarding CXCR4 potency, intestinal permeability, metabolic stability, and cytochrome P450 inhibition are presented.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Synthesis of tetrahydroisoquinoline-diamine ligands and their application in asymmetric transfer hydrogenation

The use of the tetrahydroisoquinoline scaffold is well documented in biologically active compounds. However, reports of the utilisation of tetrahydroisoquinoline compounds in asymmetric catalysis are limited. The synthesis of novel diamine ligands possessing the tetrahydroisoquinoline (tetrahydroisoquinoline) backbone and evaluation of their activity in the asymmetric transfer hydrogenation of acetophenone are presented. The diamine ligands in conjunction with i-PrOH as the hydrogen source and [RhCl2(Cp*)]2 as the metal precursor proved to be the most effective of the tetrahydroisoquinoline derivatives for this catalytic system. Water was found to have a profound influence on the enantioselectivity of the reaction. Optimisation of the amount water, i-PrOH and catalytic loading content rendered the best result of 70% enantioselectivity for the (S)-1-phenylethanol isomer product.

Total syntheses of conformationally constrained didemnin B analogues. Replacements of N2O-dimethyltyrosine with L-1,2,3,4-tetrahydroisoquinoline and L-1,2,3,4-tetrahydro-7-methoxyisoquinoline

The design and synthesis of two conformationally constrained analogues of didemnin B are described. The [N,O-Me2Tyr5]residue of didemnin B was replaced with L-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (Tic) and L-1,2,3,4-tetrahydro-7-methoxyisoquinoline-3-carboxylic acid (MeO-Tic), which mimic the N,O-dimethylated tyrosine while constraining the conformation of the molecule. Preliminary results indicate that the conformation of the [N,O-Me2Tyr5]residue closely matches the conformation imposed by the Tic replacement.

Dynamic combinatorial chemistry with hydrazones: Libraries incorporating heterocyclic and steroidal motifs

We expand the possibilities in hydrazone based dynamic combinatorial chemistry with a series of new building blocks incorporating heterocyclic motifs. The synthetic procedure allows efficient access to building blocks with the general structure (MeO)2CH-Heterocycle-C(O)NHNH2, originating from heterocycles with an amine and an ester functionality. The equilibrium distribution of macrocyclic N-acyl hydrazones formed upon deprotection of the building blocks with TFA in organic solvents is reported. The mixing behaviour of these heterocycle-based building blocks with our cholate-based building blocks is described, particularly the observation of kinetic intermediates that disappear following ‘proof-reading’.

New type of metalloproteinase inhibitor: Design and synthesis of new phosphonamide-based hydroxamic acids

A series of phosphonamide-based hydroxamate derivatives were synthesized, and the inhibitory activities were evaluated against various metalloproteinases in order to clarify its selectivity profile. Among the four diastereomeric isomers resulting from the chirality at the C-3 and P atoms, the compound with a (R,R)-configuration both at the C-3 position and the phosphorus atom was found to be potently active, while the other diastereomeric isomers were almost inactive. A number of (R,R)-compounds synthesized here exhibited broad spectrum activities with nanomolar Ki values against MMP-1, -3, -9, and TACE and also showed nanomolar IC50 values against HB-EGF shedding in a cell-based inhibition assay. The modeling study using X-ray structure of MMP-3 suggested the possible binding mode of the phosphonamide-based inhibitors.

Heterocycles [h]-Fused onto 4-oxoquinoline-3-carboxylic acid, III.1 Facile synthesis and antitumor activity of model heterocycles [a]-fused onto pyrido[2,3-f]quinoxaline-3-carboxylic acids

Direct interaction between 7-chloro-1-cyclopropyl-6-fluoro-8-nitro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid and each of (S)-proline, (2S,4R)-4-hydroxyproline and (S)-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid in hot aqueous ethanolic NaHCO3 yielded the corresponding optically pure N-(4-oxoquinolin-7-yl)-a-amino acids. The latter derivatives underwent reductive lactamization upon treatment with Na2S2O4 in aqueous ethanol to afford moderate yields of the respective pyrido[2,3-f]quinoxaline-3-carboxylic acid [fused]- to tetrahydropyrrolo[1,2-a]-, tetrahydrohydroxylpyrrolo[1,2-a]-and tetrahydroisoquinolino[2,3-a]heterocyclics 10-12, respectively. The antitumor activity against four human tumor cell lines showed that 10-12 displayed high levels of cytotoxicity as compared with Cisplatin. Interestingly, these compounds were more potent against breast carcinoma cell lines (MCF-7 and T-47D) than the lymphoid origin tumor cell lines (Jurkat and BHL-89). In particular, the (S)-proline derivative 10 exhibited preferential cytotoxicity to adherent cells (IC50 = 0.5 muM), indicative of better potential in blocking the growth of solid tumors rather than the disseminated ones.
