Rapid Cu-Catalyzed [211At]Astatination and [125I]Iodination of Boronic Esters at Room Temperature

Access to 211At- and 125I-radiolabeled compounds in excellent RCCs and RCYs was achieved in just 10 min at room temperature using a Cu catalyst. The reaction conditions are applicable to a broad class of aryl and heteroaryl boronic reagents with varying steric and electronic properties as well as late-stage astatination and iodination of anticancer PARP inhibitors. This protocol eliminates the traditional need for toxic organotin reagents, elevated temperatures, and extended reaction times, providing a more practical and environmentally friendly approach to developing alpha-emitting radiotherapeutics.

N-Chlorination-induced, oxidative ring contraction of 1,4-dimethoxyphthalazines

A rarely explored oxidative ring contraction of electron-rich 1,2-diazine is described. Upon treatment with an electrophilic chlorinating reagent (TCICA), 1,4-dimethoxyphthalazines undergo an N-chlorination-induced ring contraction that is accompanied by the loss of one nitrogen atom. The scope of this unusual reactivity was examined with a range of 1,4-dimethoxyphthalazine derivatives. In addition, a mechanism proceeding via a bicyclic species was proposed on the basis of an isolated reaction intermediate and DFT calculations.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 23928-47-4

Vasorelaxant activity of phthalazinones and related compounds

Several series of dihydrostilbenamide, imidazo[2,1-a]isoindole, pyrimido[2,1-a]isoindole and phthalazinone derivatives were obtained and their vasorelaxant activity was measured on isolated rat aorta rings pre-contracted with phenylephrine (10-5 M). Some phthalazinones attained, practically, the total relaxation of the organ at micromolar concentrations. For the most potent compound 9h (EC50 = 0.43 muM) the affinities for alpha1A, alpha1B and alpha1D adrenergic sub-receptors were determined.

Development of novel proteasome inhibitors based on phthalazinone scaffold

In this study we designed a series of proteasome inhibitors using pyridazinone as initial scaffold, and extended the structure with rational design by computer aided drug design (CADD). Two different synthetic routes were explored and the biological evaluation of the phthalazinone derivatives was investigated. Most importantly, electron positive triphenylphosphine group was first introduced in the structure of proteasome inhibitors and potent inhibition was achieved. As 6c was the most potent inhibitor of proteasome, we examined the structure-activity relationship (SAR) of 6c analogs.

Synthetic Approaches to Contemporary Drugs that Contain the Cyclopropyl Moiety

The U.S. Food and Drug Administration approved 18 new drugs that incorporate the cyclopropyl structural motif in the time frame from 2012 to 2018. This review provides an overview of synthetic approaches to these drugs with emphasis on the construction of the cyclopropyl moiety or its incorporation into the key building blocks for assembly of the highlighted drugs. Based on the structural diversity of these drugs, synthetic approaches for the construction and introduction of the cyclopropyl moiety into their structure are diverse and include: cycloalkylation (double alkylation) of CH-acids, catalytic cyclopropanation of alkenes with diazo compounds, the Simmons-Smith reaction, the Corey-Chaykovsky reaction, the Kulinkovich reaction, the Horner-Wadsworth-Emmons reaction, and cycloaddition. In addition, the cyclopropyl structure was also introduced into the drug substance intermediates via simple cyclopropyl-moiety-containing building blocks, such as cyclopropylamine, cyclopropanesulfonamide, cyclopropanecarbonyl chloride, and cyclopropylmagnesium bromide. 1 Introduction 2 Synthesis of Recently Approved Cyclopropyl-Moiety-Containing Drugs 2.1 Cabozantinib 2.2 Trametinib 2.3 Simeprevir 2.4 Ledipasvir 2.5 Olaparib 2.6 Tasimelteon 2.7 Finafloxacin 2.8 Paritaprevir 2.9 Lenvatinib 2.10 Lumacaftor 2.11 Lesinurad 2.12 Grazoprevir 2.13 Glecaprevir 2.14 Ozenoxacin 2.15 Voxilaprevir 2.16 Naldemedine 2.17 Tezacaftor 2.18 Tecovirimat 3 Conclusion.

An 18F-Labeled Poly(ADP-ribose) Polymerase Positron Emission Tomography Imaging Agent

Poly(ADP-ribose) polymerase (PARP) is involved in repair of DNA breaks and is over-expressed in a wide variety of tumors, making PARP an attractive biomarker for positron emission tomography (PET) and single photon emission computed tomography imaging. Consequently, over the past decade, there has been a drive to develop nuclear imaging agents targeting PARP. Here, we report the discovery of a PET tracer that is based on the potent PARP inhibitor olaparib (1). Our lead PET tracer candidate, [18F]20, was synthesized and evaluated as a potential PARP PET radiotracer in mice bearing subcutaneous glioblastoma xenografts using ex vivo biodistribution and PET-magnetic resonance imaging techniques. Results showed that [18F]20 could be produced in a good radioactivity yield and exhibited specific PARP binding allowing visualization of tumors over-expressing PARP. [18F]20 is therefore a potential candidate radiotracer for in vivo PARP PET imaging.

The discovery of phthalazinone-based human H1 and H3 single-ligand antagonists suitable for intranasal administration for the treatment of allergic rhinitis

A series of potent phthalazinone-based human H1 and H 3 bivalent histamine receptor antagonists, suitable for intranasal administration for the potential treatment of allergic rhinitis, were identified. Blockade of H3 receptors is thought to improve efficacy on nasal congestion, a symptom of allergic rhinitis that is currently not treated by current antihistamines. Two analogues (56a and 56b) had slightly lower H1 potency (pA2 9.1 and 8.9, respectively, vs 9.7 for the clinical gold-standard azelastine, and H3 potency (pK i 9.6 and 9.5, respectively, vs 6.8 for azelastine). Compound 56a had longer duration of action than azelastine, low brain penetration, and low oral bioavailability, which coupled with the predicted low clinical dose, should limit the potential of engaging CNS-related side-effects associated with H 1 or H3 antagonism.
