Aerobic oxidative alpha-iodination of carbonyl compounds using molecular iodine activated by a nitrate-based catalytic system

The novel reaction system comprising air/NH4NO3(cat.)/I2/H2SO4(cat.)is introduced as a simple, safe, cheap, efficient, and regioselective mediator for direct aerobic oxidative alpha-iodination of aryl, heteroaryl, alkyl, and cycloalkyl methyl ketones. The reaction system enabled the moderate to quantitative regioselective iodination of a large range of different methyl ketone derivatives including those bearing oxidizable heteroatom (S, N) substituents. Several activated aromatic compounds were also efficiently and selectively iodinated. The practical applicability of the presented reaction system was shown on 20 mmol scale under ambient pressure and 100% conversion of substrate was achieved.

Discovery of 6-substituted 4-anilinoquinazolines with dioxygenated rings as novel EGFR tyrosine kinase inhibitors

It had been reported that some dioxygenated rings fusing with the quinazoline scaffold could lead to new EGFR inhibitors. Based on this, several kinds of oxygenated alkane quinazoline derivatives were synthetized and evaluated as EGFR inhibitors. Their antiproliferative activities were tested against four cancer cell lines: A431, MCF-7, A549, and B16-F10. Most derivatives could counteract EGF-induced EGFR phosphorylation, and their potency was comparable to the reference compound Erlotinib. The size of the fused dioxygenated ring was crucial for the biological activity and the heptatomic ring derivative 19 showed potent in vitro inhibitory activity in the enzymatic assay as well as in the cellular assay.

Design, synthesis and biological evaluation of oxygenated chalcones as potent and selective MAO-B inhibitors

The present study documents the synthesis of oxygenated chalcone (O1?O26) derivatives and their abilities to inhibit monoamine oxidases. All 26 derivatives examined showed potent inhibitory activity against MAO-B. Compound O23 showed the greatest inhibitory activity against MAO-B with an IC50 value of 0.0021 muM, followed by compounds O10 and O17 (IC50 = 0.0030 and 0.0034 muM, respectively). In addition, most of the derivatives potently inhibited MAO-A and O6 was the most potent inhibitor with an IC50 value of 0.029 muM, followed by O3, O4, O9, and O2 (IC50 = 0.035, 0.053, 0.072, and 0.082 muM, respectively). O23 had a high selectivity index (SI) value for MAO-B of 138.1, and O20 (IC50 value for MAO-B = 0.010 muM) had an extremely high SI of >4000. In dialysis experiments, inhibitions of MAO-A and MAO-B by O6 and O23, respectively, were recovered to their respective reversible reference levels, demonstrating both are reversible inhibitors. Kinetic studies revealed that O6 and O23 competitively inhibited MAO-A and MAO-B, respectively, with respective Ki values of 0.016 ± 0.0007 and 0.00050 ± 0.00003 muM. Lead compound are also non-toxic at 200 mug/mL in normal rat spleen cells. Molecular docking simulations and subsequent Molecular Mechanics/Generalized Born Surface Area calculations provided a rationale that explained experimental data.

Cytotoxic small molecule dimers and their inhibitory activity against human breast cancer cells

Small molecules based upon natural product dimers that exhibit cytotoxic activity were synthesized and evaluated for their anti-proliferative activity in human breast cancer cell lines. A central isophthalic core structure linking aromatic amines containing 3,5-disubstitutions produced the most active compounds. This series of compounds was found to be more active against the estrogen receptor positive cell line MCF-7 than the estrogen receptor negative cell line, SKBr3.

HIV protease inhibitors possessing a novel, high-affinity, and achiral P1?/P2? ligand with a unique pattern of in vitro resistance. Importance of a conformationally-restricted template in the design of enzyme inhibitors

Achiral pyran-2-one analogs possessing a 3-S-(2-alkylphenyl) group were determined to be high-affinity inhibitors for human immunodeficiency virus (HIV) protease (PR). Crystallographic, modeling, and structure-activity studies led to the 3-S-(2-tert-butylphenyl) moiety as an apparent optimal group to access the S2?/S1? pockets of the enzyme. Further optimization led to an inhibitor, 3-[(2-tert-butylphenyl)sulfanyl]-4-hydroxy-6-(3-methylphenyl)-pyran-2-one (14), possessing a Ki of 3 nM. An X-ray crystallographic structure of an inhibitor, 4-hydroxy-3-[(2-isopropylphenyl)sulfanyl]-6-phenylpyran-2-one (8), bound to HIV PR showed that the 3-S-(2-isopropylphenyl) group occupied the P2? and P1? pockets, while other crucial interactions were common to those found with other pyran-2-one analogs. The high potency observed for this series may be due, in part, to the restrictions on the intramolecular collapsibility of these molecules in aqueous solution, leading to a highly favorable hydrophobic effect on binding. Herein we report a novel P2?/P1? achiral ligand which results in a tight-binding inhibitor that occupies only three pockets in the enzyme and exhibits a unique pattern of in vitro resistance.

Process development of the synthetic route to sulamserod hydrochloride

Sulamserod hydrochloride is a potent S-HT4 receptor antagonist and was a clinical candidate for the treatment of gastrointestinal disorders. Process development of the fairly long synthetic route (12 linear, 14 overall steps) was undertaken. Process improvements were highlighted by aromatic chlorination choices in making dichlorobenzodioxan 2 and acetylaminochloroketone 7, a transfer hydrogenation reducing a nitro group and simultaneous aromatic dechlorination without ketone reduction to give aminoketone 5, and use of the potential mutagenic iodosulfonamide 14 to make quaternary salt 11. The chemistry was scaled-up into pilot plant reactor vessels to produce multikilogram amounts of Sulamserod hydrochloride suitable for drug development.

Quinolinyl-Thienyl Chalcones as Monoamine Oxidase Inhibitors and their in Silico Modeling Studies

Mitochondrial enzymes, monoamine oxidases (MAO) are thought to be emerging and useful therapeutic target for neurodegenerative disorders. Monoamine oxidases have two isoforms, A and B. MAO-A is related to metabolism of amine neurotransmitters in the brain whereas MAO-B is concerned with aging related neurodegenerative disorders. Therefore, the identification, characterization and discovery of new and potent MAO-A and B inhibitors is crucial in advancing neurodegenerative therapeutic research. A series of quinolinyl-thienyl chalcones were tested against MAO-A and B and most of them revealed potent MAO-A and B inhibition. Compound 5i exhibited most potent MAO-A inhibition activity, having IC50 value of 0.047 muM, while 4l showed maximum inhibitory potency against MAO-B having IC50 value of 0.063 muM. Molecular modelling studies were performed against human MAO-A and MAOB to rationalize most probable binding site interactions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C10H10O3, you can also check out more blogs about2879-20-1
