Structure-Activity Relationship Studies of Substituted 2-(Isoxazol-3-yl)-2-oxo-N?-phenyl-acetohydrazonoyl Cyanide Analogues: Identification of Potent Exchange Proteins Directly Activated by cAMP (EPAC) Antagonists

Exchange proteins directly activated by cAMP (EPAC) as guanine nucleotide exchange factors mediate the effects of the pivotal second messenger cAMP, thereby regulating a wide variety of intracellular physiological and pathophysiological processes. A series of novel 2-(isoxazol-3-yl)-2-oxo-N?-phenyl-acetohydrazonoyl cyanide EPAC antagonists was synthesized and evaluated in an effort to optimize properties of the previously identified high-throughput (HTS) hit 1 (ESI-09). Structure-activity relationship (SAR) analysis led to the discovery of several more active EPAC antagonists (e.g., 22 (HJC0726), 35 (NY0123), and 47 (NY0173)) with low micromolar inhibitory activity. These inhibitors may serve as valuable pharmacological probes to facilitate our efforts in elucidating the biological functions of EPAC and developing potential novel therapeutics against human diseases. Our SAR results have also revealed that further modification at the 3-, 4-, and 5-positions of the phenyl ring as well as the 5-position of the isoxazole moiety may allow for the development of more potent EPAC antagonists.

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.SDS of cas: 130371-64-1, you can also check out more blogs about130371-64-1

1,2-Difunctionalization of Aryl Triflates: A Direct and Modular Access to Diversely Functionalized Anilines

ortho-Amino difunctionalization of aryl triflates has been achieved via a three-component reaction. The cascade reaction proceeds through a zincate base-mediated deprotonative formation of a reactive aryne intermediate, in situ nucleophilic addition, and coupling with electrophilic partners. This strategy leverages the advantageous reactivity of organozincate intermediates, enabling the installation of various functionalities such as amine, azide, oxygen, sulfur, halide, alkynyl, aryl, vinyl, and alkyl groups in a modular manner for the synthesis of diverse aniline skeletons.

Palladium(II)-Catalyzed Sp3/Sp2 gamma- and delta-C-H Functionalization of Aryl Amines using 5-Methylisoxazole-3-Carboxamide as Directing Group

A dual objective-based study comprising exploration of 5-methylisoxazole-3-carboxamide (MICA) as a directing group (DG) for the Pd(II)-catalyzed sp3/sp2 gamma- and delta-C?H activation/functionalization of aryl amines and assembling of various MICA motifs are reported. The Pd(II)-catalyzed MICA-aided gamma-C(sp3)-H arylation/acetoxylation of ortho-toluidines gave various 2-aminodiphenylmethanes and 2-aminobenzyl acetates, respectively. The Pd(II)-catalyzed MICA-aided gamma-C(sp2)-H arylation/acetoxylation of benzylamines gave the corresponding arylated/acetoxylated products. Furthermore, the Pd(II)-catalyzed MICA-aided delta-C(sp2)-H amidation/alkenylation of phenethylamines were also explored. Representative control reactions were done to assess the relative effectiveness of MICA for the gamma-C(sp3)-H arylation and MICA is a removable DG. Apart from the usage of MICA as a DG for the sp2/sp3 C?H functionalization of aryl amines, indirectly this process has led to the construction of a library of MICA motifs. This is an added advantage to note as the MICA-based motifs are valuable small molecules in medicinal chemistry.

Synthesis and biological evaluation of novel 2,4-diaminoquinazoline derivatives as SMN2 promoter activators for the potential treatment of spinal muscular atrophy

Proximal spinal muscular atrophy (SMA) is an autosomal recessive disorder characterized by death of motor neurons in the spinal cord that is caused by deletion and/or mutation of the survival motor neuron gene (SMN1). Adjacent to SMN1 are a variable number of copies of the SMN2 gene. The two genes essentially differ by a single nucleotide, which causes the majority of the RNA transcripts from SMN2 to lack exon 7. Although both SMN1 and SMN2 encode the same Smn protein amino acid sequence, the loss of SMN1 and incorrect splicing of SMN2 have the consequence that Smn protein levels are insufficient for the survival of motor neurons. The therapeutic goal of our medicinal chemistry effort was to identify small-molecule activators of the SMN2 promoter that, by up-regulating gene transcription, would produce greater quantities of full-length Smn protein. Our initial medicinal chemistry effort explored a series of C5 substituted benzyl ether based 2,4-diaminoquinazoline derivatives that were found to be potent activators of the SMN2 promoter; however, inhibition of DHFR was shown to be an off-target activity that was linked to ATP depletion. We used a structure-guided approach to overcome DHFR inhibition while retaining SMN2 promoter activation. A lead compound 11a was identified as having high potency (EC50 = 4 nM) and 2.3-fold induction of the SMN2 promoter. Compound 11a possessed desirable pharmaceutical properties, including excellent brain exposure and long brain half-life following oral dosing to mice. The piperidine compound 11a up-regulated expression of the mouse SMN gene in NSC-34 cells, a mouse motor neuron hybrid cell line. In type 1 SMA patient fibroblasts, compound 11a induced Smn in a dose-dependent manner when analyzed by immunoblotting and increased the number of intranuclear particles called gems. The compound restored gems numbers in type I SMA patient fibroblasts to levels near unaffected genetic carriers of SMA.

RORgamma antagonists and inverse agonists: a patent review

Introduction: The transcription factor RORgamma plays a critical role in the expression of pro-inflammatory cytokine interleukin IL-17 and is therefore an attractive target for the treatment of inflammatory diseases. Interest in this molecular target has been heightened by the advancement of orally and topically administered RORgamma modulators into clinical trials. Areas covered: The present review seeks to summarize published patent applications from assignee companies that have disclosed Investigational New Drug (IND) filings for small molecule RORgamma/RORgammat antagonists and inverse agonists. Expert opinion: The field of RORgamma research is extremely competitive, with the majority of companies targeting psoriasis as the primary disease indication. Vitae Pharmaceuticals is currently the most advanced, with a potential first-in-class oral RORgamma-modulator for the treatment of psoriasis. Future efforts will likely expand into potential applications of RORgamma-modulators in the lesser explored immune-related areas of rheumatoid arthritis, type 1 diabetes, lupus, and irritable bowel disorder, as well as cancer immunotherapy and castration-resistant prostate cancer.

Selective and Solvent-Free Synthesis of Isoxazole-Containing Spiro-Thiazolidinones Using TiO2-SO3H as Solid Catalyst

A solvent-free nano-titania-supported sulfonic acid [nano-TiO2-SO3H (n-TSA)] catalyzed approach has been developed for the synthesis of pharmaceutically interesting new hybrids of isoxazolyl-spiro-thiazolidinones. The key feature of present investigated three component reaction of cyclic ketones (isatin, ninhydrin and acenaphthenequinone), 3-amino-5-methyl-isoxazole and alpha-mercaptocarboxylic acids involves the synthesis of a five member ring system instead of the anticipated seven member ring system & also exploits the possibility of other likely isomers, regio and diastereoselectively. The selectivity of synthesized spiro-thiazolidinone systems was established, based on the spectroscopic outcome and single crystal X-ray analyses of representative compounds. Further, the use of a solid catalyst, n-TSA under solvent-free conditions was observed to be the best choice of reaction conditions, as it not only afforded the product in higher yields in less reaction time but in an environmentally friendly manner as well.
