Small-molecule MDM2/X inhibitors and PROTAC degraders for cancer therapy: advances and perspectives

Blocking the MDM2/X-P53 protein-protein interaction has been widely recognized as an attractive therapeutic strategy for the treatment of cancers. Numerous small-molecule MDM2 inhibitors have been reported since the release of the structure of the MDM2-P53 interaction in 1996, SAR405838, NVP-CGM097, MK-8242, RG7112, RG7388, DS-3032b, and AMG232 currently undergo clinical evaluation for cancer therapy. This review is intended to provide a comprehensive and updated overview of MDM2 inhibitors and proteolysis targeting chimera (PROTAC) degraders with a particular focus on how these inhibitors or degraders are identified from starting points, strategies employed, structure-activity relationship (SAR) studies, binding modes or co-crystal structures, biochemical data, mechanistic studies, and preclinical/clinical studies. Moreover, we briefly discuss the challenges of designing MDM2/X inhibitors for cancer therapy such as dual MDM2/X inhibition, acquired resistance and toxicity of P53 activation as well as future directions.

Hydrothermal liquefaction of protein-containing biomass: study of model compounds for Maillard reactions

The potential application of bio-oil production from nitrogen-containing biomass via hydrothermal liquefaction (HTL) may be limited due to high nitrogen content, making this product oil unsuitable for fuel-related uses. The Maillard reaction is expected to play a most significant role in the interaction between proteins and carbohydrates during the hydrothermal treatment. To evaluate the Maillard reaction network in this process, lactose, maltose, and lysine were employed as model substances and tested individually and in binary mixtures. HTL experiments were conducted at temperatures between 250 and 350 A degrees C and at 20 min reaction time. When treated individually, conversion of lysine leads to higher bio-oil yields (5-17 wt.%) than the model carbohydrates (6-10 wt.%) during HTL. In mixtures with carbohydrates, the measured bio-oil yields exceeded those obtained from conversion of the single substances (10-39 wt.%). Both yields and the relative nitrogen content of the bio-oil, increase with rising reaction temperature. The composition of the bio-oils obtained through HTL experiments was investigated in more detail: cyclopentenes and furfurals were obtained from disaccharide decomposition, piperidines and quinolines in the bio-oil originate from lysine, pyrazine and its derivatives are obtained from the mixture of lysine and disaccharides. A reaction scheme based on key chemical compounds accompanied with functional groups identified by FT-IR and NMR was developed to provide a better understanding of the Maillard reaction and its impact during HTL of protein-containing biomass.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 477600-74-1, you can contact me at any time and look forward to more communication. SDS of cas: 477600-74-1.

Synthesis of tetrafluorinated piperidines from nitrones via a visible-light-promoted annelation reaction

A method for the one-step construction of 3,3,4,4-tetrafluorinated piperidines from nitrones and readily accessible tetrafluorinated iodobromobutane is described. The reaction requires an excess amount of ascorbic acid as the terminal reductant and is performed in the presence of an iridium photocatalyst activated by blue light. The annelation is a result of a radical addition at the nitrone, intramolecular nucleophilic substitution, and reduction of the N-O bond.

Asymmetric Organocatalytic Synthesis of Bisindoles – Scope and Derivatizations

Starting from 3-vinylindoles and glyoxolate imines, we created a library of diverse 4,6-bis(1H-indole-3-yl)piperidine 2-carboxylates by using 10 mol-% of a chiral phosphoric acid. Utilising electron-withdrawing groups on the starting material during the reaction led to the formation of Povarov-type structures, which extended the previous library of molecules. Furthermore, we could demonstrate that consecutive reactions like reductions, cross coupling reactions or click reactions on bisindoles are feasible.

Synthesis of Diastereomeric Pyrrolidine Sulfamides via Anchimerically Assisted Nucleophilic Substitution Reactions

The Mitsunobu reaction was employed in a key step during the development of a convenient synthetic route for the enantioselective preparation of pyrrolidine-sulfamide ligands from (R)-or (S)- [(S)-1-benzylpyrrolidin-2-yl](phenyl) methanol, and employing tert-butyl pyrrolidin-1-yl-sulfonylcarbamate as a non-conventional nucleophilic source. Although it is well documented that the exposure of this type of diastereomeric amino alcohols to the above-mentioned nucleophile usually leads to the formation of piperidines via ring expansion, either through classical nucleophilic substitution or the Mitsunobu version, only the pyrrolidine derivatives were generated with retention of configuration on the exocyclic stereocenter, owing to the neighboring group participation (internal backside nucleophilic substitution, S(N)ib). Final removal of the N-Boc protecting group from the sulfamide fragment afforded chiral compounds with significant potential as chiral ligands in asymmetric catalysis.

Modulation of mean arterial pressure and diuresis by renomedullary infusion of a selective inhibitor of fatty acid amide hydrolase

The kidneys contribute to the control of body fluid and electrolytes and the long-term regulation of blood pressure through various systems, including the endocannabinoid system. Previously, we showed that inhibition of the two major endocannabinoid-hydrolyzing enzymes, fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase, in the renal medulla increased the rate of urine excretion (UV) and salt excretion without affecting mean arterial pressure (MAP). The present study evaluated the effects of a selective FAAH inhibitor, N-3pyridinyl-4-[[3-[[5-(trifluoromethyl)-2-pyridinyl] oxy] phenyl] methyl]-1-piperidine carboxamide (PF-3845) on MAP and renal functions. Infusion of PF-3845 into the renal medulla of C57BL/6J mice reduced MAP during the posttreatment phases and increased UV at 15 and 30 nmol/min per gram kidney weight (g kwt), relative to the pretreatment control phase. Intravenous PF-3845 administration reduced MAP at the 7.5, 15, and 30 doses and increased UV at the 15 and 30 nmol.min(-1) g(-1) kwt doses. PF-3845 treatment elevated sodium and potassium urinary excretion and medullary blood flow. Homozygous FAAH knockout mice were refractory to intramedullary PF-3845-induced changes in MAP, but UV was increased. Both MAP and UV responses to intramedullary PF-3845 in C57BL/6J mice were diminished by pretreatment with the cannabinoid type 1 receptor-selective antagonist, rimonabant (3 mg/kg, ip) but not the cyclooxygenase 2-selective inhibitor, celecoxib (15 mg/kg, iv). Liquid chromatography-tandem mass spectrometry analyses showed increased anandamide in kidney tissue and 2-arachidonoyl glycerol in plasma after intramedullary PF-3845. These data suggest that inhibition of FAAH in the renal medulla leads to both a diuretic and blood pressure-lowering response mediated by elevated anandamide in kidney tissue or 2-arachidonoyl glycerol in plasma.
