Synthetic gene delivery systems employ multiple functions to enable safe and effective transport of DNA to target cells. Here, we describe metabolite-based poly(L-lysine) (PLL) modifiers that improve transfection by imparting both pH buffering and nanoparticle stabilization functions within a single molecular unit. PLL modifiers were based on morpholine (M), morpholine and niacin (MN), or thiomorpholine (TM). PLL modification with (MN) or (TM) imparted buffering function over the pH range of 57 both in solution and live cells and enhanced the stability of PLL DNA nanoparticles, which exhibited higher resistance to polyanion exchange and prolonged blood circulation. These properties translated into increased transfection efficiency in vitro coupled with reduced toxicity compared to unmodified PLL and PLL(M). Furthermore, PEG-PLL(MN) DNA nanoparticles transfected muscle tissue in vivo for >45 days following intramuscular injection. These polymer modifiers demonstrate the successful design of multifunctional units that improve transfection of synthetic gene delivery systems while maintaining biocompatibility.

The design and synthesis of related molecules that are more effective, more selective, and less toxic than aspirin are important objectives of biomedical research. You can also check out more blogs about 98-03-3. Quality Control of Thiophene-2-aldehyde.

In a article, author is Fanigliulo, Ameriga, introduce new discover of the category.

A stability-indicating method for the determination of S-carboxymethyl-L-cysteine and related degradation impurities in Exputex (R) 250 mg/5 mL syrup was developed in anion-exchange liquid chromatography mode. A forced degradation study supported the method development to ensure stability indicating conditions. Aqueous solutions of the active pharmaceutical ingredient and syrup samples at different pH-values were stress-tested in different thermal, light exposure and headspace conditions. One degradation product was detected in thermal stress studies at 60 degrees C and 80 degrees C in the pH range 5.0-7.0 and was identified by mass spectrometry as 5-oxo-thiomorpholine-3-carboxylic acid (lactam of carbocysteine). A second degradation product was only generated in moderately strong oxidizing conditions (0.5% H2O2 aqueous solution) and was identified as S-carboxymethyl-L-cysteine-(R/S)-sulphoxide (carbocysteine sulphoxide). The method was developed on a Zorbax SAX column, in isocratic mode. The mobile phase consisted of 200 mM phosphate solution at pH 4.0 and acetonitrile (50:50 v/v) and UV detection was performed at a wavelength of 205 nm. The method was linear for carbocysteine (R > 0.9982) over a concentration range of 2.5-50 mu g/mL and 0.4-0.6 mg/mL. Linearity for the impurities was shown from the LOQ to 50 mu g/mL. Specificity was verified and accuracy demonstrated for the active ingredient and its degradation products in syrup samples at 3 levels around their respective specification limits. Repeatability, intermediate precision and inter-laboratory reproducibility were assessed on three commercial batches, analyzed in triplicate by two operators at both the transferring and the receiving site and demonstrated a successful method transfer to the manufacturing quality control laboratory.

Binary alpha-Unsaturated Palladium Carboxylates and Their Complexes with Morpholine Derivatives: the Crystal Structure of Palladium Carbamoyl Crotonate (OC4H8NH)(2)Pd[OC4H8N(C=O)](MeCH=CHCO2) center dot H2O, a Product of the First Inner-Sphere Amination Reaction of alpha-Unsaturated Palladium Carbonyl Carboxylates with Morpholine

Binary alpha-unsaturated palladium carboxylates have been synthesized by substitution of alpha-unsaturated acids RCOOH (R is CH2=C(Me), MeCH=CH, PhCH=CH) for the acetate ion in Pd-3(mu-MeCOO)(6). These carboxylates react with amines A (A is morpholine (M), methylmorpholine (MM), or thiomorpholine (MS)) to give trans-Pd(A)(2)(RCOO)(2) similar to trans-A(2)(MeCO2)(2). The structures of the trans-Pd(A)(2)(RCOO)(2) complexes (R is MeCH=CH; A is M, MM, MS) have been determined by X-ray crystallography. The effect of solvent on the crystal structure of the complexes has been demonstrated for trans-(MeCH=CHCO2)(2)Pd(C4H9NO)(2) as an example. The amination reaction of palladium carbonyl crotonate with a secondary amine, morpholine, has been studied for the first time. The reaction involves disproportionation of Pd(I) into Pd(0) and Pd(II) and leads to the first unsaturated palladium(II) carbamoyl carboxylate-palladium carbamoyl crotonate trans-(OC4H8NH)(2)Pd[OC4H8NC(=O)](MeCH=CHCO2) center dot H2O, as well as to trans-M2Pd(MeCH=CHCO2)(2) and (C4H10NO)(+)(MeCH=CHCO2)(-). The structures of these compounds have been proved by X-ray crystallography.

Intramolecular [3+2]-Cycloadditions of Azomethine Ylides Derived from Secondary Amines via Redox-Neutral C-H Functionalization

Azomethine ylides are accessed under mild conditions via benzoic acid catalyzed condensations of 1,2,3,4-tetrahydroisoquinolines or tryptolines with aldehydes bearing a pendent dipolarophile. These intermediates undergo intramolecular [3 + 2]-cycloadditions in a highly diastereoselective fashion to form polycyclic amines with four new stereogenic centers. Challenging substrates such as piperidine, morpholine, and thiomorpholine undergo the corresponding reactions at elevated temperatures.
