Tarr, James C. published the artcileTargeting Selective Activation of M₁ for the Treatment of Alzheimer’s Disease: Further Chemical Optimization and Pharmacological Characterization of the M₁ Positive Allosteric Modulator ML169, Computed Properties of 763120-58-7, the publication is ACS Chemical Neuroscience (2012), 3(11), 884-895, database is CAplus and MEDLINE.

The M₁ muscarinic acetylcholine receptor is thought to play an important role in memory and cognition, making it a potential target for the treatment of Alzheimer’s disease (AD) and schizophrenia. Moreover, M₁ interacts with BACE1 and regulates its proteasomal degradation, suggesting selective M₁ activation could afford both palliative cognitive benefit as well as disease modification in AD. A key challenge in targeting the muscarinic acetylcholine receptors is achieving mAChR subtype selectivity. Our lab has previously reported the M₁ selective pos. allosteric modulator ML169. Herein we describe our efforts to further optimize this lead compound by preparing analog libraries and probing novel scaffolds. We were able to identify several analogs that possessed submicromolar potency, with our best example displaying an EC₅₀ of 310 nM. The new compounds maintained complete selectivity for the M₁ receptor over the other subtypes (M₂-M₅), displayed improved DMPK profiles, and potentiated the carbachol (CCh)-induced excitation in striatal MSNs. Selected analogs were able to potentiate CCh-mediated non-amyloidogenic APPα release, further strengthening the concept that M₁ PAMs may afford a disease-modifying role in the treatment of AD.

Lu, Jinzhen published the artcileHeteroligand Molecular “Stirrups” Using Conformationally Flexible Ditopic Pyridyl-Pyrazolyl Ligands, Category: pyrazoles-derivatives, the publication is Inorganic Chemistry (2009), 48(16), 7525-7527, database is CAplus and MEDLINE.

Heteroligand mol. stirrups form by the self-assembly of flexible ditopic ligands in combination with 4,4′-bipyridine and [(dppp)Pd]²⁺ [dppp = 1,3-bis(diphenylphosphino)propane]. Crystallog. anal. shows that the ligands, bis[3-(4-pyridyl)pyrazolyl]-m-xylene (mXy^4py3pz) and bis[4-(4-pyridyl)pyrazolyl]-p-xylene (pXy^4py4pz) form [{(dppp)Pd}₂(4,4′-bipy)(L)](OTf)₄ (1·4OTf and 2·4OTf, resp.) in the solid state, with remarkably similar structures considering the differences in substitution patterns between the two ligands. The self-assembly of both 1⁴⁺ and 2⁴⁺ is assisted by face-to-face π interactions on the exterior of the macrocycle between the Ph rings of the dppp ligands and the pyridyl groups of the ditopic ligands.

Karthik, Murugan published the artcileGraphene Oxide as a Carbocatalyst for Sustainable ipso-Hydroxylation of Arylboronic Acids: A Simple and Straightforward Strategy To Access Phenols, Category: pyrazoles-derivatives, the publication is ACS Sustainable Chemistry & Engineering (2019), 7(9), 9028-9034, database is CAplus.

A metal-free and straightforward protocol for the synthesis of phenols from aryl and heteroaryl boronic acids has been demonstrated using graphene oxide as a carbocatalyst. This sustainable ipso-hydroxylation takes place under mild conditions using aqueous H₂O₂ as an oxidant in a water medium in a short time under organocatalytic and base-free conditions. The control experiments reveal that the presence of carboxyl groups promotes ipso-hydroxylation. The developed methodol. offers GO as a benign solid-acid catalyst with good sustainability which can be reused several times without significant loss in its catalytic activities; this was proven by the Fourier transform IR and powder X-ray diffraction studies of the reused catalyst.

Liu, Zheng published the artcileC-3 benzoic acid derivatives of C-3 deoxybetulinic acid and deoxybetulin as HIV-1 maturation inhibitors, Application In Synthesis of 724710-02-5, the publication is Bioorganic & Medicinal Chemistry (2016), 24(8), 1757-1770, database is CAplus and MEDLINE.

A series of C-3 phenyl- and heterocycle-substituted derivatives of C-3 deoxybetulinic acid and C-3 deoxybetulin was designed and synthesized as HIV-1 maturation inhibitors (MIs) and evaluated for their antiviral activity and cytotoxicity in cell culture. A 4-subsituted benzoic acid moiety was identified as an advantageous replacement for the 3’3′-dimethylsuccinate moiety present in previously disclosed MIs that illuminates new aspects of the topog. of the pharmacophore. The new analogs exhibit excellent in vitro antiviral activity against wild-type (wt) virus and a lower serum shift when compared with the prototypical HIV-1 MI bevirimat (1, BVM), the first MI to be evaluated in clin. studies. Compound 9a exhibits comparable cell culture potency toward wt virus as 1 (WT EC₅₀ = 16 nM for 9a compared to 10 nM for 1). However, the potency of 9a is less affected by the presence of human serum, while the compound displays a similar pharmacokinetic profile in rats to 1. Hence 9a, the 4-benzoic acid derivative of deoxybetulinic acid, represents a new starting point from which to explore the design of a 2nd generation MI.

Katoh, Taisuke published the artcileDiscovery and optimization of 1,7-disubstituted-2,2-dimethyl-2,3-dihydroquinazolin-4(1H)-ones as potent and selective PKCθ inhibitors, Product Details of C3H5BN2O2, the publication is Bioorganic & Medicinal Chemistry (2016), 24(11), 2466-2475, database is CAplus and MEDLINE.

A high-throughput screening campaign helped us to identify an initial lead compound (1) as a protein kinase C-θ (PKCθ) inhibitor. Using the docking model of compound 1 bound to PKCθ as a model, structure-based drug design was employed and two regions were identified that could be explored for further optimization, i.e., (a) a hydrophilic region around Thr442, unique to PKC family, in the inner part of the hinge region, and (b) a lipophilic region at the forefront of the Et moiety. Optimization of the hinge binder led us to find 1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one as a potent and selective hinge binder, which resulted in the discovery of compound 5. Filling the lipophilic region with a suitable lipophilic substituent boosted PKCθ inhibitory activity and led to the identification of compound 10. The co-crystal structure of compound 10 bound to PKCθ confirmed that both the hydrophilic and lipophilic regions were fully utilized. Further optimization of compound 10 led us to compound 14, which demonstrated an improved pharmacokinetic profile and inhibition of IL-2 production in a mouse.

Erra, Montse published the artcileDiscovery of a Novel Inhaled PI3Kδ Inhibitor for the Treatment of Respiratory Diseases, Name: 1H-Pyrazole-4-boronic acid, the publication is Journal of Medicinal Chemistry (2018), 61(21), 9551-9567, database is CAplus and MEDLINE.

Oral PI3Kδ inhibitors such as Idelalisib and Duvelisib have shown efficacy as anticancer agents and Idelalisib has been approved for the treatment of three B-cell cancers. However, Idelalisib has a black box warning on its product label regarding the risks of fatal and serious toxicities including hepatic toxicity, severe diarrhea, colitis, pneumonitis, infections, and intestinal perforation. Some of these side effects are mechanism-related and could hinder the development of Idelalisib for less severe conditions. For respiratory diseases, compounds administered by inhalation are delivered directly to the site of action and may improve the therapeutic index of a drug, minimizing undesired side effects. This work describes the discovery and optimization of inhaled PI3Kδ inhibitors intended for the treatment of severe asthma and COPD. Once the potency was in the desired range, efforts were focused on identifying the particular physicochem. properties that could translate into better lung retention. This medicinal chem. exercise led to the identification of LAS195319 as a candidate for clin. development.
