Isoquinoline Derivatives as Potent, Selective, and Orally Active CRTH2 Antagonists

Synthesis and structure activity relationship of a novel series of isoquinoline CRTH2 antagonists bearing a methylene linker between the isoquinoline and benzamide moieties were described. Optimization focusing on the substituents of the benzamide portion in the right hand part of the molecule led to the identification of TASP0412098 (91), which is a potent, selective CRTH2 antagonist (binding affinity: IC50=2.1 nm, functional activity: IC50=12 nm). Compound 91, which was orally bioavailable in mice and guinea pigs, showed in vivo efficacy after oral administration in a bronchial asthma model of guinea pigs.

Novel calamitic liquid crystals having an electron-deficient isoquino[8,7-h]isoquinoline moiety as a core, 2,8-didecylisoquino[8,7-h]isoquinoline (10-IQIQ-10) and 2,8-didodecylisoquino[8,7-h]isoquinoline (12-IQIQ-12), were prepared, and their phase transition behaviors, HOMO and LUMO levels, and charge carrier transport properties were investigated. 12-IQIQ-12 showed a highly ordered smectic H phase at around 140 to 150 degrees C and a low-lying LUMO level of -3.33 eV. Time-of-flight measurements revealed field-independent ambipolar transport characterized by mobility on the order of 10(-4) cm(2) V-1 s(-1) at the highly ordered smectic phase.

A Simple and Effective Approach to the Synthesis of Isoquinoline Derivatives Under Solvent-Free Conditions

An efficient synthesis of dialkyl pyrrolo[2,1-a]isoquinoline-2,3-dicarboxylates, pyrrolo[1,2-a]quinoline-1,2-dicarboxylates and indolizines is described via one-pot reactions of isoquinoline, quinoline or pyridine and phenacyl bromids with dialkyl acetylenedicarboxylates or diaryloylacetylene under solvent-free conditions at 50 degrees C. The mild reaction conditions and high yields of the products exhibit the good synthetic advantage of these methods. [GRAPHICS] .

Studies on beta-ketoanilides: Synthesis of some new isoquinoline, pyrimido[4,5-c]isoquinoline and phenanthridine derivatives

The beta-ketoanilides 1a,b or 2a,b react with the activated nitriles 3a-c to give the isoquinoline derivatives 4a-e, respectively. The pyrimido (4,5-c) isoquinoline derivatives 5a,b and 6a,b were obtained by the reaction of 4a,b with carbon disulfide and/or formamide/formic acid. The phenanthridine derivatives 10 and 11 were produced by cyclization of 1a or 2a with PPA andlor POCl3 whereas the phenanthridine derivative 13 is obtained by the action of amm. acetate on 12 which is obtained from the reaction of 1a or 2a with m-cresol in the presence of PPA. The structures of the compounds have been confirmed by their IR, H-1 NMR and mass spectral data.

Cholinesterase inhibitory isoquinoline alkaloids from Corydalis mucronifera

Eight previously undescribed isoquinoline alkaloids, mucroniferanines H-M, together with 16 known isoquinoline alkaloids, were isolated from Corydalis mucronifera Maxim.. The structures of the previously undescribed compounds were elucidated by interpretation of 1D and 2D NMR spectroscopic and HAMS data, and their absolute configurations were established by computational electronic circular dichroism (ECD) calculations and X-ray diffraction data. Mucroniferanine L is reported as the first natural amide bond linked isoquinoline alkaloid dimer. The isolated compounds were evaluated for AChE and BuChE inhibitory activities and mucroniferanine H showed significant activities with IC50 values of 2.31 mu M and 36.71 mu M, respectively.
