Liu, Lulu published the artcileDesign, synthesis and biological evaluation of tyrosine derivatives as Mcl-1 inhibitors, Formula: C9H10O3, the main research area is peptidomimetic tyrosine synthesis drug design apoptosis; mol docking Mcl1 inhibitor peptidomimetic; tyrosine methyl ester bromoalkane condensation benzenesulfonamide amidation coupling; Apoptosis; Cancer; Mcl-1 inhibitors; Tyrosine derivatives.

The upregulation of the protein myeloid cell leukemia-1 (Mcl-1) is closely associated with various human cancers, which can result in the evasion of apoptosis and a low survival rate. Therefore, developing Mcl-1 inhibitors has become a promising paradigm for cancer therapy. Herein, we designed and synthesized a novel series of tyrosine derivatives, among which compounds (I) (R1 = 3,5-di-Me-4-Cl-Ph, X = H, R2 = OBut, n = 2; R1 = 3,5-di-Me-4-Cl-Ph, X = H, R2 = Ph, n = 1; R1 = naphthyl, X = Br, R2 = 4-Me-benzyl, n = 1) exhibited very high binding affinity to Mcl-1 with Ki values of 0.18, 0.27 and 0.23μM, resp. Interestingly, compound I (R1 = 3,5-di-Me-4-Cl-Ph, X = H, R2 = Ph, n = 1) showed not only potent activity against Mcl-1 but also considerable selectivity over Bcl-2 and Bcl-xL, which was rationalized by mol. docking and fragment-centric topog. mapping (FCTM). It is worth noting that compounds I (R1 = 3,5-di-Me-4-Cl-Ph, X = H, R2 = OBut, n = 2; R1 = 3,5-di-Me-4-Cl-Ph, X = H, R2 = Ph, n = 1; R1 = naphthyl, X = Br, R2 = 4-Me-benzyl, n = 1) displayed potent antiproliferative activity against several cancer cell lines and could induce apoptosis of KM3 and HepG2 cells in a dose-dependent manner.

A cascade approach to the synthesis of 5-(indol-3-yl)hydantoin framework has been developed by the reaction of indole with glyoxylic acid/pyruvic acid under a deep eutectic solution, (+)-tartaric acid-dimethylurea. N,N’-Dimethylurea from a deep eutectic solution functions as a reactant as well as a solvent mixture Isolation of the intermediate, 5-hydroxyhydantoin, and its reaction with indole provides the mechanistic evidence for this reaction. This method was successfully applied in the first total synthesis of an alkaloid, (±)-oxoaplysinopsin B, with an overall yield of 48%.

Cho, Seoyoung published the artcile1,2-Difunctionalization of Aryl Triflates: A Direct and Modular Access to Diversely Functionalized Anilines, Application In Synthesis of 5961-59-1, the main research area is aryl triflate amine iodine three component aminoiodination reaction; iodoaniline preparation; bomo methylaniline aryl triflate palladium catalyst arylation; methylcarbazole preparation.

Ortho-amino difunctionalization of aryl triflates was achieved via a three-component reaction. The cascade reaction proceeded 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.

Guguloth, Vijaya Charan published the artcileStable, reusable MoO3/ZrO2 solid acid catalyst for the synthesis of diphenylmethane viafriedel-craft alkylation under solvent free condition, Recommanded Product: 1,3-Dimethoxybenzene, the main research area is diphenylmethane molybdenum zirconium oxide solid acid catalyst.

A simple method is described for the synthesis of substituted diphenylmethane derivatives in excellent yields by friedel-craft alkylation reaction under solvent free condition using molybdenum promoted ZrO2 solid acid catalyst at 80°C. The MoO3/ZrO2 catalyst has been prepared from using impregnation method followed by calcination at 923K for 6 h in air atm. This catalyst was characterized by various techniques such as SEM, XRD, FTIR, UV DRS, and BET surface area. Zirconia has both acidic and basic properties which can be altered by incorporating suitable promoter atom like Mo which inturn increase the surface area thereby enhance the surface acidity. Impregnation of Mo ions shows a strong influence on phase modification of zirconia from thermodynamically more stable monoclinic to metastable tetragonal phase. Incorporation of promoter Mo will stabilize tetragonal phase which is active in catalyzing reactions. In friedel-craft alkylation MoO3/ZrO2 catalyst was found to be stable, efficient and environmentally friendly, easily recovered by filtration, higher yield of product and can be reusable efficiently.
