Russo Spena, Concetta published the artcileLiposomal delivery of a Pin1 inhibitor complexed with cyclodextrins as new therapy for high-grade serous ovarian cancer, Formula: C9H8Cl2O2, the publication is Journal of Controlled Release (2018), 1-10, database is CAplus and MEDLINE.

Pin1, a prolyl isomerase that sustains tumor progression, is overexpressed in different types of malignancies. Functional inactivation of Pin1 restrains tumor growth and leaves normal cells unaffected making it an ideal pharmaceutical target. Although many studies on Pin1 have focused on malignancies that are influenced by sex hormones, studies in ovarian cancer have lagged behind. Here, we show that Pin1 is an important therapeutic target in high-grade serous epithelial ovarian cancer. Knock down of Pin1 in ovarian cancer cell lines induces apoptosis and restrains tumor growth in a syngeneic mouse model. Since specific and non-covalent Pin1 inhibitors are still limited, the first liposomal formulation of a Pin1 inhibitor was designed. The drug was efficiently encapsulated in modified cyclodextrins and remotely loaded into pegylated liposomes. This liposomal formulation accumulates preferentially in the tumor and has a desirable pharmacokinetic profile. The liposomal inhibitor was able to alter Pin1 cancer driving-pathways trough the induction of proteasome-dependent degradation of Pin1 and was found to be effective in curbing ovarian tumor growth in vivo.

Using a “chiral pool” approach, a number of chiral thiolate and sulfide ligands based on natural terpenes and terpenoids have been synthesized in a few simple steps. Two new Rh-thiolate complexes with the formula [Rh(CO)₂(μ-SR)]₂ were obtained. The influence of these complexes and catalytic systems formed by combining the synthesized ligands with [Rh(CO)₂(μ-Cl)]₂ and [Rh(cod)(μ-Cl)]₂, on the reaction rate, chemoselectivity, stereoselectivity and formation of tetraphenyldisiloxane in Rh-catalyzed asym. hydrosilylation of acetophenone as a model reaction have been studied. Mechanistic aspects of formation of silyl enol ether as a side product in the presence of S-containing ligands are presented.

Grob, Jonathan E. published the artcileOne-Pot C-N/C-C Cross-Coupling of Methyliminodiacetic Acid Boronyl Arenes Enabled by Protective Enolization, Recommanded Product: 4-Chloro-2-ethoxycarbonylphenylboronic acid, the publication is Organic Letters (2012), 14(21), 5578-5581, database is CAplus and MEDLINE.

Iterative cross-coupling is a highly efficient and versatile strategy for modular construction in organic synthesis, though this has historically been demonstrated solely in the context of C-C bond formation. A C-N cross-coupling of haloarene methyliminodiacetic acid (MIDA) boronates with a wide range of aromatic and aliphatic amines is reported. Successful cross-coupling of aliphatic amines was realized only through protective enolization of the MIDA group. This reaction paradigm was subsequently utilized to achieve a one-pot C-N/C-C cross-coupling sequence.

A series of substituted BzOH esters of various alkanolamines has been prepared and tested pharmacologically. Esters of the tertiary amino alcs. were prepared either by the condensation of the corresponding dialkylaminoalkyl chloride with the Na salt of the acid (method A) or by the condensation of the acid chloride with the amino alc. in the presence of excess base (method B). The esters of secondary amines were prepared by refluxing the HCl salt of the secondary amino alc. with the acid chloride (method C). The nitro esters were reduced to the amino esters by treating the HCl salts with Fe powder in H₂O or aqueous EtOH (method D). The topical and intradermal anesthetic activities of the resulting esters were measured on guinea pig wheal and rabbit cornea, resp.; comparisons were made with cocaine or procaine, to each of which the value 1 was assigned; the acute toxicities were determined in albino mice.

Gemcitabine-loaded SVAs containing synthesized PAHy derivatives were characterized from the physicochem. and technol. point of view and the in vitro toxicity and anticancer activity on two different human cancer cell lines, i.e., CaCo-2 (human colon carcinoma) and ARO (human anaplastic thyroid carcinoma) cells, were also evaluated. Moreover, considering that carrier-cell interaction is an important factor to achieve an improvement of anticancer drug activity, confocal laser scanning microscopy and flow cytometric experiments were carried out on the two different cancer cell lines.

Pierson, R. M. published the artcileBis-type modifiers in polymerization. I. Behavior of various disulfides in bulk styrene polymerization, Recommanded Product: 1,2-Bis(2-chloroethyl)disulfane, the publication is Journal of Polymer Science (1955), 221-46, database is CAplus.

Studies were made of the effectiveness in low-conversion bulk styrene polymerizations of the modifiers, bis(2-ethylhexyl) disulfide, dibenzyl disulfide, bis(chlorobenzyl) disulfide, bis[2-(2-pyridyl)ethyl] disulfide, bis(2-chloroethyl)disulfide, bis(2-hydroxyethyl)disulfide, dithiodiacetic acid, esters of bis(2-carboxyethyl)disulfide, bis(2-chloroacetoxyethyl) disulfide, diphenyl disulfide, di-ο-tolyl disulfide, bis(2,6-xylyl) disulfide, bis(2,3,5,6-tetramethylphenyl) disulfide, bis(4-carboxyphenyl) disulfide, bis(4-carbethoxyphenyl) disulfide, bis(4-hydroxymethylphenyl)disulfide, bis(2-chloromethylphenyl) disulfide, bis(2-bromomethylphenyl)disulfide, bis(2-aminophenyl) disulfide, di-2-naphthyl disulfide, di-2-benzothiazolyl disulfide, bis(isopropylxanthogen) disulfide, 4,4′-dithiodimorpholine disulfide, carbonylbis(thioglycolic acid), thiocarbonylbis(thioglycolic acid), and tetraphenylhydrazine. Alkyl disulfides, even when substituted at C’s near the SS bond, had very low transfer constants The transfer constants of aryl disulfides were much higher and could be increased by substitutions, thereby incorporating desired groups into the polymer. They cleave to give one half the mol. to each end of the polymer as was shown by comparing end-group concentrations of styrene polymers containing various types of end groups with polymers modified by thiols containing similar groups.

Guirado, Gonzalo published the artcileElectrochemical Remote Control for Dithienylethene-Ferrocene Switches, Recommanded Product: 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, the publication is Journal of Physical Chemistry C (2007), 111(6), 2770-2776, database is CAplus.

The electrochromic properties of dithienylethene derivatives is a field of great importance and interest. In this manuscript the authors describe a potential mol. remote control system, which can be electrochem. triggered. Diferrocenyl compounds containing a diethylenene photoelectrochromic core with perhydro- and perfluorocyclopentene ring were prepared to induce a change in the chromic properties via an intramol. electron-transfer reaction from the redox group to the photochromic core. The electrochem. behavior of open and closed isomers was thoroughly studied using photochem., electrochem., and spectroelectrochem. techniques. The 1st redox couple was typically assigned to the ferrocene for the open isomer. However, for the closed isomer, an electrocatalytic ring-opening process was observed for the perhydrocyclopentene ring, while a slightly different electrochem. process was observed for the perfluorocyclopentene system. Mechanistic studies revealed that an internal charge transfer is necessary to destabilize the closed bridge. Once opened, the bridge’s cation radical is a strong oxidant, and the charge eventually gets localized on the ferrocene. The charges then migrate throughout the solution by self-exchange reactions. Hence, the redox status of the Fc units triggers the photochrom’s reactivity playing the role of antenna that can temporarily store a charge and facilitate the transformation. This way to perform the transformation, i.e., by electrochem. rather than photochem., presents the great advantage of being much more local and, thus, would permit the ultimate stage of miniaturization at the scale of just one ol.
