2-[3-[2-[(25)-2-cyano-1-pyrrolidinyl]-2-oxoethylamino]-3-methyl-1-oxobutyl] -1,2,3,4-tetrahydroisoquinoline: A potent, selective, and orally bioavailable dipeptide-derived inhibitor of dipeptidyl peptidase IV

Dipeptidyl peptidase IV (DPP-IV) inhibitors are expected to become a new type of antidiabetic drugs. Most known DPP-IV inhibitors often resemble the dipeptide cleavage products, with a proline mimic at the P1 site. As off-target inhibitions of DPP8 and/or DPP9 have shown profound toxicities in the in vivo studies, it is important to develop selective DPP-IV inhibitors for clinical usage. To achieve this, a new class of 2-[3-[[2-[(2S)-2-cyano-1-pyrrolidinyl]-2- oxoethyl]amino]-1-oxopropyl]-based DPP-IV inhibitors was synthesized. SAR studies resulted in a number of DPP-IV inhibitors, having IC50 values of <50 nM with excellent selectivity over both DPP8 (IC50 > 100 muM) and DPP-II (IC50 > 30 muM). Compound 21a suppressed the blood glucose elevation after an oral glucose challenge in Wistar rats and also inhibited plasma DPP-IV activity for up to 4 h in BALB/c mice. The results show that compound 21a possesses in vitro and in vivo activities comparable to those of NVP-LAF237 (4), which is in clinical development. 2006 American Chemical Society.

Chemoenzymatic Approach to (S)-1,2,3,4-Tetrahydroisoquinoline Carboxylic Acids Employing D-Amino Acid Oxidase

Optically pure 1,2,3,4-tetrahydroisoquinoline carboxylic acids constitute an important class of building blocks for the synthesis of natural products and synthetic pharmaceuticals. However, redox deracemization of racemic 1,2,3,4-tetrahydroisoquinoline carboxylic acids as an attractive method is still challenging for the lack of suitable oxidoreductases. Herein, a D-amino acid oxidase from Fusarium solani M-0718 (FsDAAO) with broad substrate scope and excellent enantioselectivity was exploited through genome mining, and applied for the kinetic resolution of a number of racemic 1- and 3-carboxyl substituted tetrahydroisoquinolines to yield the corresponding (S)-enantiomers with excellent enantiomeric excess (ee) values (up to >99%). By using FsDAAO in combination with ammonia-borane in one pot, deracemization of these racemic carboxyl-substituted tetrahydroisoquinolines was achieved with conversions up to >98% and >99% ee. Preparative-scale deracemization of racemic 1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid and 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid was also demonstrated with good isolated yields (82% and 73%, respectively) and ee>99%. Our study provides an effective method for the synthesis of enantiomeric pure 1,2,3,4-tetrahydroisoquinoline carboxylic acids. This method is expected to provide access to chiral carboxyl-substituted 1,2,3,4-tetrahydroquinolines and 1,2,3,4-tetrahydro-ss-carbolines. (Figure presented.).

Debenzylation of tertiary amines using phosgene or triphosgene: An efficient and rapid procedure for the preparation of carbamoyl chlorides and unsymmetrical ureas. Application in carbon-11 chemistry

Efficient and rapid preparations of carbamoyl chlorides and unsymmetrical ureas from tertiary amines and phosgene or its safe equivalent triphosgene [bis(trichloromethyl)carbonate, BTC] are described. First, the reaction of stoichiometric amounts of phosgene with secondary amines was revisited, and it was shown that the formation of carbamoyl chlorides in high yields required careful adjustments of experimental conditions and the use of pyridine as an HCl scavenger. A phosgene-mediated dealkylation of triethylamine was observed when this base was used instead of pyridine. Taking advantage of this observation, a strategy of synthesis of carbamoyl chlorides from tertiary amines and phosgene has been developed. N-Alkyl-N-benzyl(substituted)tetrahydroisoquinolines, -piperazines, -piperidines, or -anilines were treated with stoichiometric amounts of phosgene (or BTC) in CH2Cl2. Tertiary amines bearing electron-enriched benzyl group(s) afforded carbamoyl chlorides in excellent yields and without any contamination by symmetrical ureas. Subsequent additions of primary or secondary amines to these carbamoyl chlorides produced unsymmetrical ureas in single-pot and high-yielding operations. This methodology was applied in 11C-chemistry. From [ 11C]phosgene, a common precursor used in the preparation of radiotracers for positron emission tomography, a rapid and efficient synthesis of 11C-carbamoyl chlorides and 11C-unsymmetrical ureas derived from tetrahydroisoquinoline and piperazine is described. The first example of 11C-amide formation from the reaction of a 11C-carbamoyl chloride and an organometallic (cyanocuprate or a Grignard reagent in the presence of a nickel catalyst) is also presented.

From mixed sigma-2 receptor/P-glycoprotein targeting agents to selective P-glycoprotein modulators: Small structural changes address the mechanism of interaction at the efflux pump

Generations of modulators of the efflux pump P-glycoprotein (P-gp) have been produced as tools to counteract the Multidrug Resistance (MDR) phenomenon in tumor therapy, but clinical trials were not successful so far. With the aim of contributing to the development of novel P-gp modulators, we started from recently studied high-affinity sigma-2 (sigma2) receptor ligands that showed also potent interaction with P-gp. For sigma2 receptors high-affinity binding, a basic N-atom is a strict requirement. Therefore, we reduced the basic character of the N-atom present in these ligands, and we obtained potent P-gp modulators with poor or null sigma2 receptor affinity. We also evaluated whether modulation of P-gp by these novel compounds involved consumption of ATP (as P-gp substrates do), as a source of energy to support the efflux. Surprisingly, even small structural changes resulted in opposite behavior, with amide 13 depleting ATP, in contrast to its isomer 18. Two compounds, 15 and 25, emerged for their potent activity at P-gp, and deserve further investigations as tools for P-gp modulation.

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

Luminescent palladium(II) complexes with pi-extended cyclometalated [R-C^N^N-R?] and pentafluorophenylacetylide ligands: Spectroscopic, photophysical, and photochemical properties

A series of cyclometalated PdII complexes that contain pi-extended R-C^N^N-R? (R-C^N^N-R?=3-(6?-aryl-2?- pyridinyl)isoquinoline) and chloride/pentafluorophenylacetylide ligands have been synthesized and their photophysical and photochemical properties examined. The complexes with the chloride ligand are emissive only in the solid state and in glassy solutions at 77 K, whereas the ones with the pentafluorophenylacetylide ligand show phosphorescence in the solid state (lambdamax=584-632 nm) and in solution (lambdamax=533- 602 nm) at room temperature. Some of the complexes with the pentafluorophenylacetylide ligand show emission with lambdamax at 585-602 nm upon an increase in the complex concentration in solutions. These PdII complexes can act as photosensitizers for the light-induced aerobic oxidation of amines. In the presence of 0.1 mol % PdII complex, secondary amines can be oxidized to the corresponding imines with substrate conversions and product yields up to 100 and 99 %, respectively. In the presence of 0.15 mol % PdII complex, the oxidative cyanation of tertiary amines could be performed with product yields up to 91 %. The Pd II complexes have also been used to sensitize photochemical hydrogen production with a three-component system that comprises the PdII complex, [Co(dmgH)2(py)Cl] (dmgH=dimethylglyoxime; py=pyridine), and triethanolamine, and a maximum turnover of hydrogen production of 175 in 4 h was achieved. The excited-state electron-transfer properties of the PdII complexes have been examined. Copyright
