PEGylated polyplex micelles from triblock catiomers with spatially ordered layering of condensed pDNA and buffering units for enhanced intracellular gene delivery

An A-B-C type triblock copolymer, tandemly aligning two types of polycations with different pKa values in a single polymer strand, was developed for the construction of novel polyplex micelles, satisfying a high DNA condensing ability as well as a proton buffering activity directed to elevating gene transfection. The micelle might feature the distinctive three-layered structure, where an inner polyplex layer of condensed pDNA with poly(l-lysine) (pKa ?9.4) as the C segment is successively wrapped with an intermediate layer of poly[(3-morpholinopropyl)aspartamide] (B segment) with a comparatively low pKa of?6.2, to provide a buffering effect, and an outer PEG layer (A segment) as a biocompatible palisade.

Pd NPs Decorated on POPs as Recyclable Catalysts for the Synthesis of 2-Oxazolidinones from Propargylic Amines via Atmospheric Cyclizative CO2 Incorporation

A novel approach has been taken for the synthesis of a microporous polymeric materials of BBA-1 and BBA-2 (benzene?benzylamine), which is a POP (porous organic polymer) with its excellent surface area determined by BET study, via Friedel-Crafts alkylation of benzene and benzylamine (or 4-methoxybenzylamine) by utilizing a cross-linker (formaldehyde dimethyl acetal) and a promoter (anhydrous FeCl3). Pd NPs were decorated over BBA-1 and modified BBA-2 to generate the desired catalysts (Pd@BBA-1 and Pd@BBA-2 respectively). The characterizations of the synthesized nanomaterials have been conducted by FE-SEM, wide-angle powder XRDmethods, N2 adsorption/desorption studies and high resolution transmission electron microscopy (TEM). Pd NPs decorated porous polymers are described here to facilitate the carboxylative cyclization of several propargylamine derivatives leading to the corresponding desired products (2-oxazolidinone) under the application of ambient conditions (0.1 MPa of CO2, DMSO, 40?80 C, 30?60 mg nanocatalyst). The Pd NPs-loaded POP is competitive with previously reported catalytic systems. These pure polymeric microporous catalytic systems exhibited outstanding catalytic performances for the generation of oxazolidinones from several propargylic amines in the absence of organic and inorganic bases through atmospheric cyclizative CO2 incorporation. The modified nanocatalyst (Pd@BBA-2) displayed exceptional recycling efficiency for the generation of oxazolidinones up to five runs without any noticeable decay in the activity of Pd@BBA-2.

Synthesis and structure-activity relationships of long-acting beta2 adrenergic receptor agonists incorporating metabolic inactivation: An antedrug approach

A series of saligenin beta2 adrenoceptor agonist antedrugs having high clearance were prepared by reacting a protected saligenin oxazolidinone with protected hydroxyethoxyalkoxyalkyl bromides, followed by removal of the hydroxy-protecting group, alkylation, and final deprotection. The compounds were screened for beta2, beta1, and beta3 agonist activity in CHO cells. The onset and duration of action in vitro of selected compounds were assessed on isolated superfused guinea pig trachea. Compound 13f had high potency, selectivity, fast onset, and long duration of action in vitro and was found to have long duration in vivo, low oral bioavailability in the rat, and to be rapidly metabolized. Crystalline salts of 13f (vilanterol) were identified that had suitable properties for inhaled administration. A proposed binding mode for 13f to the beta2-receptor is presented.

Methyl-thiazoles: A novel mode of inhibition with the potential to develop novel inhibitors targeting InhA in mycobacterium tuberculosis

InhA is a well validated Mycobacterium tuberculosis (Mtb) target as evidenced by the clinical success of isoniazid. Translating enzyme inhibition to bacterial cidality by targeting the fatty acid substrate site of InhA remains a daunting challenge. The recent disclosure of a methyl-thiazole series demonstrates that bacterial cidality can be achieved with potent enzyme inhibition and appropriate physicochemical properties. In this study, we report the molecular mode of action of a lead methyl-thiazole, along with analogues with improved CYP inhibition profile. We have identified a novel mechanism of InhA inhibition characterized by a hitherto unreported “Y158-out” inhibitor-bound conformation of the protein that accommodates a neutrally charged “warhead”. An additional novel hydrophilic interaction with protein residue M98 allows the incorporation of favorable physicochemical properties for cellular activity. Notably, the methyl-thiazole prefers the NADH-bound form of the enzyme with a Kd of ?13.7 nM, as against the NAD+-bound form of the enzyme.

Process for the activation of carboxylic acids

A process for the activation of carboxylic acids which is useful for the subsequent conversion of said carboxylic acids into their corresponding amides or esters, based on reacting a 2-oxazolidinone with phosphorus pentachloride and subsequent addition of a salt of the carboxylic acid to be activated.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C3H5NO2, you can also check out more blogs about497-25-6
