Soucy, C.; Favreau, D.; Kayser, M. M. published the artcile< The regioselectivity of metal hydride reductions of 3-substituted phthalic anhydrides>, Category: bromides-buliding-blocks, the main research area is phthalide substituted; phthalic anhydride substituted hydride reduction; regiochem reduction substituted phthalic anhydride.

The reduction of 3-methoxyphthalide by metal hydrides was reinvestigated. Various effects controlling selectivity of reductions in 3-substituted phthalides were studied, and a qual. interpretation of the results was proposed. Methods for obtaining enhanced yields of one or the other lactonic product were developed.

Journal of Organic Chemistry published new progress about LUMO (molecular orbital). 82-73-5 belongs to class bromides-buliding-blocks, and the molecular formula is C8H3BrO3, Category: bromides-buliding-blocks.

Kil, Kun-Eek; Poutiainen, Pekka; Zhang, Zhaoda; Zhu, Aijun; Choi, Ji-Kyung; Jokivarsi, Kimmo; Brownell, Anna-Liisa published the artcile< Radiosynthesis and Evaluation of an 18F-Labeled Positron Emission Tomography (PET) Radioligand for Metabotropic Glutamate Receptor Subtype 4 (mGlu4)>, COA of Formula: C8H3BrO3, the main research area is fluorine labeled PET radioligand metabotropic glutamate receptor subtype 4; chlorophenylpicolinamide phthalimide derivative fluorine labeled PET radioligand mGlu4.

Four 4-phthalimide derivatives of N-(3-chlorophenyl)-2-picolinamide were synthesized as potential ligands for the PET imaging of mGlu4 in the brain. Of these compounds, N-(3-chloro-4-(4-fluoro-1,3-dioxoisoindolin-2-yl)phenyl)-2-picolinamide (3, III, KALB001) exhibited improved binding affinity (IC50 = 5.1 nM) compared with ML128 (1, I) and was subsequently labeled with 18F. When finally formulated in 0.1 M citrate buffer (pH 4) with 10% ethanol, the specific activity of [18F]3 at the end of synthesis (EOS) was 233.5 ± 177.8 GBq/μmol (n = 4). The radiochem. yield of [18F]3 was 16.4 ± 4.8% (n = 4), and the purity was over 98%. In vivo imaging studies in a monkey showed that the radiotracer quickly penetrated the brain with the highest accumulation in the brain areas known to express mGlu4. Despite some unfavorable radiotracer properties like fast washout in rodent studies, [18F]3 is the first 18F-labeled mGlu4 radioligand, which can be further modified to improve pharmacokinetics and brain penetrability for future human studies.

Patel, Harun; Chaudhari, Kavita; Jain, Pritam; Surana, Sanjay published the artcile< Synthesis and in vitro antitubercular activity of pyridine analouges against the resistant Mycobacterium tuberculosis>, Application In Synthesis of 82-73-5, the main research area is pyridinyl hydrazide preparation antitubercular activity SAR; Schiff base pyridinyl preparation antitubercular activity SAR; Cytotoxicity; MDR-MTB; Mycobacterium tuberculosis; Synthesis.

Synthesis and the biol. activity of isoniazid and pyridine derivatives were successfully carried out with elaborated characterization by spectral data. Amongst the synthesized compounds; I and II displayed encouraging antimycobacterial activity with IC50 of 3.2μM and 1.5μM against the H37Rv strain. The MIC of test compounds I and II were also assessed against the 5 drug resistant isolates (FQ-R1, INH-R1, INH-R2, RIF-R1 and RIF-R2) of MTB strains under aerobic conditions and compound I [MIC = 3.2μM for FQ-R1; MIC = 140μM for INH-R1; MIC = 160μM for INH-R2; MIC = 2.4μM towards RIF-R1; MIC = 4.2μM for RIF-R2] and II [MIC = 3.3μM for FQ-R1; MIC = 170μM for INH-R1; MIC = 190μM for INH-R2; MIC = 1.8μM for RIF-R1; MIC = 8.4μM for RIF-R2] have shown significant activity at non-cytotoxic concentration in comparison to the standard drug.
