Bcr-Abl threonine 315 to isoleucine 315 (T315I) gatekeeper mutation induced drug resistance remains an unmet clin. challenge for the treatment of chronic myeloid leukemia (CML). Chem. degradation of Bcr-AblT315I protein has become a potential strategy to overcome drug resistance. Herein, we first described the design, synthesis, and evaluation of a new class of selective Bcr-AblT315I proteolysis-targeting chimeric (PROTAC) degraders based on GZD824 (reported as Bcr-AblT315I inhibitor by our group). One of the degrader 7o with 6-member carbon chain linkage with pomalidomide exhibits the most potent degradation efficacy with DR of 69.89% and 94.23% at 100 and 300 nmol/L, resp., and has an IC50 value of 26.8 ± 9.7 nmol/L against Ba/F3T315I cells. Further, 7o also displays substantial tumor regression against Ba/F3-Bcr-AblT315I xenograft model in vivo.

Ottosen, Erik Rytter published the artcileSynthesis and structure-activity relationship of aminobenzophenones. A novel class of p38 MAP kinase inhibitors with high antiinflammatory activity, HPLC of Formula: 452-63-1, the main research area is aminobenzophenone preparation structure activity MAP kinase inhibitor antiinflammatory; skin inflammation aminobenzophenone preparation structure activity MAP kinase inhibitor; dermatitis aminobenzophenone preparation structure activity MAP kinase inhibitor antiinflammatory; human aminobenzophenone preparation structure activity MAP kinase inhibitor antiinflammatory; kinase phosphorylating MAP inhibitor aminobenzophenone preparation structure activity; tumor necrosis factor kinase MAP inhibitor aminobenzophenone preparation; interleukin tumor necrosis factor kinase MAP inhibitor aminobenzophenone preparation; inflammation inhibitor aminobenzophenone preparation structure activity p38 MAP kinase.

The synthesis and structure-activity relationship (SAR) of a series of 4-aminobenzophenones, as a novel compound class with high antiinflammatory activity, was reported. The initial lead, [4-[(2-aminophenyl)amino]phenyl](phenyl)methanone, was systematically optimized and resulted in compounds that potently inhibited the release of the proinflammatory cytokines IL-1β and TNF-α in human peripheral blood mononuclear cells stimulated by LPS. One of the most potent compounds, among others, was [4-[(2-aminophenyl)amino]-2-chlorophenyl](2-methylphenyl)methanone (I) with IC50 values of 14 and 6 nM for the inhibition of IL-1β and TNF-α, resp. Furthermore, these types of compounds were found to be potent and selective p38 MAP kinase inhibitors, e.g. I had an IC50 value of 10 nM. Mol. modeling was used to rationalize our SAR data and to propose a model for the interaction of I with the p38 MAP kinase. The model involved a favorable hydrogen bond between the carbonyl group of the benzophenone and the NH of Met-109, positioning ring A in the hydrophobic pocket I of the enzyme. Good antiinflammatory effects were demonstrated in two murine models of dermatitis after topical application (oxazolone and TPA model).

Farn, Shiou-Shiow published the artcileAntiinflammation Derived Suzuki-Coupled Fenbufens as COX-2 Inhibitors: Minilibrary Construction and Bioassay, Synthetic Route of 452-63-1, the main research area is antiinflammation Suzuki coupled fenbufen COX inhibitor minilibrary construction bioassay; COVID-19; COX-2 selectivity; biaryl; inflammasome; synergistic.

A small fenbufen library comprising 18 compounds was prepared via Suzuki Miyara coupling. The five-step preparations deliver 9-17% biphenyl compounds in total yield. These fenbufen analogs exert insignificant activity against the IL-1 release as well as inhibiting cyclooxygenase 2 considerably. Both the para-amino and para-hydroxy mono substituents display the most substantial COX-2 inhibition, particularly the latter one showing a comparable activity as celecoxib. The most COX-2 selective and bioactive disubstituted compound encompasses one electron-withdrawing Me and one electron-donating fluoro groups in one arene. COX-2 is selective but not COX-2 to bioactive compounds that contain both two electron-withdrawing groups; disubstituted analogs with both resonance-formable electron-donating dihydroxy groups display high COX-2 activity but inferior COX-2 selectivity. In silico simulation and modeling for three COX-2 active-p-fluoro, p-hydroxy and p-amino-fenbufens show a preferable docking to COX-2 than COX-1. The most stabilization by the p-hydroxy fenbufen with COX-2 predicted by theor. simulation is consistent with its prominent COX-2 inhibition resulting from experiments

Sun, Xicheng published the artcileDiscovery of S-Nitrosoglutathione Reductase Inhibitors: Potential Agents for the Treatment of Asthma and Other Inflammatory Diseases, HPLC of Formula: 1208318-08-4, the main research area is nitrosoglutathione reductase inhibitor preparation asthma inflammation; GSNO; GSNOR; N6022; asthma; nitric oxide; pyrrole.

S-Nitrosoglutathione reductase (GSNOR) regulates S-nitrosothiols (SNOs) and nitric oxide (NO) in vivo through catabolism of S-nitrosoglutathione (GSNO). GSNOR and the anti-inflammatory and smooth muscle relaxant activities of SNOs, GSNO, and NO play significant roles in pulmonary, cardiovascular, and gastrointestinal function. In GSNOR knockout mice, basal airway tone is reduced and the response to challenge with bronchoconstrictors or airway allergens is attenuated. Consequently, GSNOR has emerged as an attractive therapeutic target for several clin. important human diseases. As such, small mol. inhibitors of GSNOR were developed. These GSNOR inhibitors were potent, selective, and efficacious in animal models of inflammatory disease characterized by reduced levels of GSNO and bioavailable NO. N6022, a potent and reversible GSNOR inhibitor, reduced bronchoconstriction and pulmonary inflammation in a mouse model of asthma and demonstrated an acceptable safety profile. N6022 is currently in clin. development as a potential agent for the treatment of acute asthma.

DeVries, Vern G. published the artcileHypolipidemic alkoxybenzoic acids, Application In Synthesis of 56523-59-2, the main research area is hypolipidemic alkoxybenzoic acid derivative; benzoic acid alkoxy derivative hypolipidemic.

A series of ∼90 p-alkoxybenzoic acids (I) with aromatic ring substituents or modified alkyl or unsaturated chains (R1), prepared by alkylation of the appropriate hydroxybenzoate ester followed by saponification, was screened in rats for serum-sterol and triglyceride lowering activity. Alkyl chain substituents such as chloro and oximino enhanced activity, while azido, thiol, and some alkylthio groups resulted in retention of activity. Some alkylthio substituents on the alkyl chain and aryl ring substituents abolished sterol-lowering activity. The effect of alkyl chain branching was variable, while unsaturation had no adverse effect on activity except when located near either end of the chain.

Kelly, Martha J. published the artcileDiscovery of 2-[3,5-Dichloro-4-(5-isopropyl-6-oxo-1,6-dihydropyridazin-3-yloxy)phenyl]-3,5-dioxo-2,3,4,5-tetrahydro[1,2,4]triazine-6-carbonitrile (MGL-3196), a Highly Selective Thyroid Hormone Receptor β Agonist in Clinical Trials for the Treatment of Dyslipidemia, Related Products of bromides-buliding-blocks, the main research area is tetrahydrotriazinecarbonitrile derivative MGL3196 thyroid hormone receptor agonist dyslipidemia treatment.

The beneficial effects of thyroid hormone (TH) on lipid levels are primarily due to its action at the thyroid hormone receptor β (THR-β) in the liver, while adverse effects, including cardiac effects, are mediated by thyroid hormone receptor α (THR-α). A pyridazinone series has been identified that is significantly more THR-β selective than earlier analogs. Optimization of this series by the addition of a cyanoazauracil substituent improved both the potency and selectivity and led to MGL-3196 (53), which is 28-fold selective for THR-β over THR-α in a functional assay. Compound 53 showed outstanding safety in a rat heart model and was efficacious in a preclin. model at doses that showed no impact on the central thyroid axis. In reported studies in healthy volunteers, 53 exhibited an excellent safety profile and decreased LDL cholesterol (LDL-C) and triglycerides (TG) at once daily oral doses of 50 mg or higher given for 2 wk.

Li, Zhiqiang published the artcilePhotoresponsive supramolecular coordination polyelectrolyte as smart anticounterfeiting inks, Synthetic Route of 913836-27-8, the main research area is photoresponsive supramol coordination polyelectrolyte anticounterfeiting ink.

While photoluminescence printing is a widely applied anticounterfeiting technique, there are still challenges in developing new generation anticounterfeiting materials with high security. Here we report the construction of a photoresponsive supramol. coordination polyelectrolyte (SCP) through hierarchical self-assembly of lanthanide ion, bis-ligand and diarylethene unit, driven by metal-ligand coordination and ionic interaction. Owing to the conformation-dependent photochromic fluorescence resonance energy transfer between the lanthanide donor and diarylethene acceptor, the ring-closure/ring-opening isomerization of the diarylethene unit leads to a photoreversible luminescence on/off switch in the SCP. The SCP is then utilized as security ink to print various patterns, through which photoreversible multiple information patterns with visible/invisible transformations are realized by simply alternating the irradiation with UV and visible light. This work demonstrates the possibility of developing a new class of smart anticounterfeiting materials, which could be operated in a noninvasive manner with a higher level of security.

Trost, Barry M. published the artcileSulfones as Synthetic Linchpins: Transition-Metal-Free sp3-sp2 and sp2-sp2 Cross-Couplings Between Geminal Bis(sulfones) and Organolithium Compounds, Application of 2-Bromo-4-methoxybenzoic acid, the main research area is substituted dihydronaphthalene preparation; geminal bis sulfone organolithium compound coupling; cross-coupling; sulfones; synthesis design; transition-metal-free; umpolung.

A valuable umpolung strategy that highlights the ambiphilic nature of the bis(phenylsulfonyl)methyl synthons and demonstrates its utility as a synthetic linchpin is reported. Alkyl- and aryllithiums couple with the central carbon of the bis(phenylsulfonyl)methyl unit to ultimately generate trisubstituted alkenes I [R = H, 6-MeO, 7-F, etc.; R1 = n-Bu, Ph, (CH2)2C6H5, etc.], comprising formal sp3-sp2 and sp2-sp2 cross-couplings between organolithium reagents and bis(sulfones). This process occurs almost instantaneously at -78 °C in the absence of any transition metals. By developing this curious transformation, it has been demonstrated that bis(phenylsulfonyl)methane is a valuable synthetic linchpin, which can undergo two C-C bond-forming processes as an sp3-nucleophile, followed by a third C-C bond-forming reaction as an effective sp2-electrophile. This discovery significantly enhances the utility of this ubiquitous, but underutilized, linker group.
