A Mild Method for Making MIDA Boronates
Kelly, Aidan M.,Chen, Peng-Jui,Klubnick, Jenna,Blair, Daniel J.,Burke, Martin D.
supporting information, p. 9408 - 9414 (2020/09/15)
We disclose that a predried form of methyliminodiacetic acid (MIDA), MIDA anhydride, acts as both a source of the MIDA ligand and an in situ desiccant to enable a mild and simple MIDA boronate synthesis procedure. This method expands the range of sensitive boronic acids that can be converted into their MIDA boronate counterparts. Further utilizing unique properties of MIDA boronates, we have developed a MIDA Boronate Maker Kit which enables the direct preparation and purification of MIDA boronates from boronic acids using only heating and centrifuge equipment that is widely available in laboratories that do not specialize in organic synthesis.
CROSSLINKERS FOR MASS SPECTROMETRIC IDENTIFICATION AND QUANTITATION OF PEPTIDES
-
Paragraph 0063-0064, (2019/04/08)
Crosslinking molecules that permit efficient identification of specifically associated proteins and the sites of crosslinking in biological or other samples include two cleavable bonds that are cleavable under the same conditions as peptide bonds in mass spectrometric determinations. Sets of the invention crosslinkers may be provided with isobaric labels containing reporter ions of differing molecular weights to permit relative quantitation of crosslinked protein pairs.

Insulin degrading enzyme (IDE) is a zinc metalloprotease that degrades small amyloid peptides such as amyloid-a and insulin. So far the dearth of IDE-specific pharmacological inhibitors impacts the understanding of its role in the physiopathology of Alzheimer's disease, amyloid-a clearance, and its validation as a potential therapeutic target. Hit 1 was previously discovered by high-throughput screening. Here we describe the structure-activity study, that required the synthesis of 48 analogues. We found that while the carboxylic acid, the imidazole and the tertiary amine were critical for activity, the methyl ester was successfully optimized to an amide or a 1,2,4-oxadiazole. Along with improving their activity, compounds were optimized for solubility, lipophilicity and stability in plasma and microsomes. The docking or co-crystallization of some compounds at the exosite or the catalytic site of IDE provided the structural basis for IDE inhibition. The pharmacokinetic properties of best compounds 44 and 46 were measured in vivo. As a result, 44 (BDM43079) and its methyl ester precursor 48 (BDM43124) are useful chemical probes for the exploration of IDE's role.

The present invention relates to a compound represented by the formula (I'): wherein each symbol is as defined in the specification, provided that 2-(2-((4-cyanophenyl)amino)-2-oxoethoxy)-N-(9-ethyl-9H-carbazol-3-yl)acetamide and N-(4-cyanophenyl)-N'-(9-ethyl-9H-carbazol-3-yl)-3-methylpentanediamide are excluded, or a salt thereof.
Methods for Forming Protected Organoboronic Acids
-
Page/Page column 15-16, (2011/09/14)
Described are methods of forming protected boronic acids that provide in a manner that is straightforward, scalable, and cost-effective a wide variety of building blocks, such as building blocks containing complex and/or pharmaceutically important structures, and/or provide simple or complex protected organoboronic acid building blocks. A first method includes reacting an imino-di-carboxylic acid and an organoboronate salt. A second method includes reacting a N-substituted morpholine dione and an organoboronic acid.
Structure-activity relationships of new N-acylanthranilic acid derivatives as plasminogen activator inhibitor-1 inhibitors
Yamaoka, Nagahisa,Kodama, Hidehiko,Izuhara, Yuko,Miyata, Toshio,Meguro, Kanji
experimental part, p. 215 - 224 (2011/04/16)
Novel anthranilic acid derivatives having substituted N-acyl side chains were designed and synthesized for evaluation as plasminogen activator inhibitor-1 (PAI-1) inhibitors. Compounds with a 4-diphenylmethyl-1-piperazinyl moiety on the acyl side chains in general exhibited potent in vitro PAI-1 inhibitory activity and good pharmacokinetic profiles after oral administration in rats. Compound 16f (TM5275) was identified as a promising candidate for further pharmacological evaluation.

A series of 4-oxo-4H-pyrido[1,2-a]pyrimidine derivatives, derivatized at the 2-position with carbon-linked substituents, were synthesized and evaluated for their ability to potentiate the activity of the fluoroquinolone levofloxacin (LVFX) and the anti-pseudomonas β-lactam aztreonam (AZT) in Pseudomonas aeruginosa. Palladium-catalyzed cross-coupling methods were applied for the incorporation of aliphatic and aromatic substituents.
