Dianati, Vahid published the artcileIncreasing C-Terminal Hydrophobicity Improves the Cell Permeability and Antiproliferative Activity of PACE4 Inhibitors against Prostate Cancer Cell Lines, Application of (E)-4-(2-Nitrovinyl)benzonitrile, the publication is Journal of Medicinal Chemistry (2018), 61(18), 8457-8467, database is CAplus and MEDLINE.

The serine protease, PACE4, is a proprotein convertase that plays a substantial role in malignancy of prostate cancer. Our initial selective PACE4 inhibitor (Ac-LLLLRVKR-NH₂) has evolved to the current lead compound C23 (Ac-DLeu-LLLRVK-Amba), which is active both in vitro and in vivo. By screening natural residues, except Cys, in C-terminal P1′ position, it was established that increasing hydrophobicity was improving cell permeability, which was directly translated into PCa cells antiproliferative activity. This cell antiproliferation enhancement seems independent from effect of P1′ residue on PACE4 affinity. Replacement of P1-Amba of C23 by Acpa ((S)-2-amino-3-(4-carbamimidoylphenyl)propanoic acid) followed by addition of tryptamine in P1′ resulted in compound 32 exhibiting superior PCa cells antiproliferative activity over the reference compound C23 (3-fold). This study sheds light on key factors that improve cell penetrating property and antiproliferative activity of PACE4 inhibitors.

Giri, Ramesh published the artcileSynthetic Applications of Pd(II)-Catalyzed C-H Carboxylation and Mechanistic Insights: Expedient Routes to Anthranilic Acids, Oxazolinones, and Quinazolinones, HPLC of Formula: 68569-14-2, the publication is Journal of the American Chemical Society (2010), 132(2), 686-693, database is CAplus and MEDLINE.

A Pd(II)-catalyzed reaction protocol for the carboxylation of ortho-C-H bonds in anilides to form N-acyl anthranilic acids has been developed. This reaction procedure provides a novel and efficient strategy for the rapid assembly of biol. and pharmaceutically significant mols., such as benzoxazinones and quinazolinones, from simple anilides without installing and removing an external directing group. The reaction conditions are also amenable to the carboxylation of N-phenylpyrrolidinones. A monomeric palladacycle containing p-toluenesulfonate as an anionic ligand has been characterized by X-ray crystallog., and the crucial role of p-toluenesulfonic acid in the activation of C-H bonds in the presence of carbon monoxide is discussed. Identification of two key intermediates, a mixed anhydride and benzoxazinone formed by reductive elimination from organometallic Ar(CO)Pd(II)-OTs species, provides mechanistic evidence for a dual-reaction pathway.

Freeman, Fillmore published the artcileReaction of aminopropanedinitrile 4-methylbenzenesulfonate [aminomalononitrile p-toluenesulfonate (tosylate)] with aromatic aldehydes, SDS of cas: 5098-14-6, the publication is Journal of Organic Chemistry (1991), 56(2), 657-63, database is CAplus.

(NC)₂CHNH₂·HO₃SC₆H₄Me-4 reacts with aromatic aldehydes in NaOAc-MeOH to give diastereoselectively (E,E)-RCH:NC(CN):C(NH₂)OMe (R = C₆H₄R¹-4, R¹ = OMe, OEt, OAc, H, Br, NO₂, CO₂Me; R = 3-pyridyl, 3-thienyl) and trans-3,6-diaryl-2,2,5,5-tetracyanopiperazines I (same R). The product distribution depends on the ratio of reactants and the structures of the substrates. Electron-releasing groups on the 4-position of the Ph ring favor piperazine formation. The formation of piperazines may involve synthetically useful N-protonated aryl- and cyano-stabilized azomethine ylide (prototropic 1,3-dipoles) intermediates which could have resulted from an imine-azomethine ylide tautomerism of prior formed 1-aryl-3,3-dicyano-2-aza-1-propenes. [4+2]-1,3-Dipolar cycloaddition reactions of the highly reactive azomethine ylides with MeO₂CCCCO₂Me give 3,4-dicarbomethoxy-2-cyano-5-aryl-3-pyrrolines, which undergo facile dehydrocyanation to 3,4-dicarbomethoxy-2-cyano-5-arylpyrroles. The possible intermediacy of ketenimines and of aryl- and cyano-stabilized 2-azaallyl anionic intermediates in equilibrium with azomethine ylides is also considered.

Kang, Taeho published the artcileNickel-Catalyzed 1,2-Carboamination of Alkenyl Alcohols, Recommanded Product: 4-(5,5-Dimethyl-1,3,2-dioxaborinan-2-yl)benzonitrile, the publication is Journal of the American Chemical Society (2021), 143(34), 13962-13970, database is CAplus and MEDLINE.

An alc.-directed, nickel-catalyzed three-component umpolung carboamination of unactivated alkenes with aryl/alkenylboronic esters and electrophilic aminating reagents was reported. This transformation was enabled by specifically tailored O-(2,6-dimethoxybenzoyl)hydroxylamine electrophiles that suppressed competitive processes, including undesired β-hydride elimination and transesterification between the alc. substrate and electrophile. The reaction delivered the desired 1,2-carboaminated products with generally high regio- and syn-diastereoselectivity and exhibited a broad scope of coupling partners and alkenes, including complex natural products. Various mechanistic experiments and anal. of the stereochem. outcome with a cyclic alkene substrate, as confirmed by X-ray crystallog. anal., support alc.-directed syn-insertion of an organonickel(I) species.

Lim, Ji Woong published the artcileIdentification of crizotinib derivatives as potent SHIP2 inhibitors for the treatment of Alzheimer’s disease, COA of Formula: C8H6ClN, the publication is European Journal of Medicinal Chemistry (2018), 405-422, database is CAplus and MEDLINE.

SH2 domain-containing inositol 5′-phosphatase 2 (SHIP2) is a lipid phosphatase that produces phosphatidylinositol 3,4-bisphosphate (PI(3,4)P₂) from phosphatidylinositol 3,4,5-triphosphate (PI(3,4,5)P₃), and is involved in many diseases such as neurodegenerative diseases. A recent report demonstrating that SHIP2 inhibition decreased tau hyperphosphorylation induced by amyloid β and rescued memory impairment in a transgenic Alzheimer’s disease mouse model indicates SHIP2 can be a promising therapeutic target for Alzheimer’s disease. In the present study, the authors have developed novel, potent SHIP2 inhibitors by extensive structural elaboration of crizotinib discovered from a high-throughput screening. The authors’ representative compound 43 ((R)-5-(5-(1-(2,6-dichloro-3-fluorophenyl)ethoxy)pyridin-3-yl)pyrimidin-2-amine) potently inhibited SHIP2 activity as well as GSK3β activation in HT22 neuronal cells. It was also shown that 43 has favorable physicochem. properties, especially high brain penetration. Considering SHIP2 is one of key signal mediators for tau hyperphosphorylation, the authors’ potent SHIP2 inhibitor 43 may function as a promising lead compound for the treatment of Alzheimer’s disease.
