Chem. modified siRNAs were synthesized to enhance the corresponding silencing activities. The introduced modifications endowed siRNAs with high silencing effect, long RNAi persistence, and better serum resistance. Theor. data allowed us to correlate the observed siRNAs interfering performance with the peculiar interactions with PAZ.

Olmstead, Marilyn M. published the artcileCrystal and molecular structure of chloramine-T trihydrate. Absence of a sodium-nitrogen interaction in the oxidant. N-chloro-N-sodiotoluene-p-sulfonamide, Product Details of C7H13ClNNaO5S, the publication is Inorganic Chemistry (1986), 25(22), 4057-8, database is CAplus.

The title compound is triclinic, space group PT, with a 6.393(1), b 7.510(1)8 c 13.767(2) Å, α 85.33(1), β 83.92(1), and γ 74.11(1)°; Z = 2. Final R = 0.039 for 2366 data. At. coordinates are given. The main feature of the structure involves the lack of the commonly represented interaction between Na and N. Instead, the Na ion is coordinated to one of the sulfonamide oxygens. The rest of the Na coordination sphere involves oxygens (from water of crystallization) and a Cl from a neighboring mol. The structure is the first for an [RSO₂NCl]^– moiety.

Alagiri, Kaliyamoorthy published the artcileCatalyst-Free Regio- and Stereospecific Synthesis of β-Sulfonamido Dithiocarbamates: Efficient Ring-Opening Reactions of N-Tosyl Aziridines by Dialkyldithiocarbamates, COA of Formula: C7H13ClNNaO5S, the publication is Chemistry – A European Journal (2011), 17(25), 6922-6925, S6922/1-S6922/62, database is CAplus and MEDLINE.

We have developed an efficient protocol for the synthesis of β-sulfonamido dithiocarbamates by using a ring-opening strategy of aziridines by thiocarbamates. These methods avoid toxic catalysts and, in most cases, give nearly quant. yields without any byproducts. This strategy provides an elegant method for synthesizing a wide range of β-sulfonamido dithiocarbamates by using inexpensive and readily available starting materials. In addition, a one-pot method has been developed for a facile ring-opening of aziridines by using in situ generated dialkyldithiocarbamate. This methodol. could potentially prove useful for the synthesis of medicinally active and other com. dithiocarbamate derivatives

Ramacharyulu, P. V. R. K. published the artcilePhotocatalytic decontamination of sulfur mustard using titania nanomaterials, Application of 1,2-Bis(2-chloroethyl)disulfane, the publication is Journal of Molecular Catalysis A: Chemical (2012), 132-137, database is CAplus.

Photocatalytic decontamination of sulfur mustard (HD) was studied on titania nanomaterials, and data obtained with irradiation of sunlight and UV-A light were compared with that obtained without irradiation Role of particle size on photocatalytic decontamination of HD was also studied. Decontamination efficiency decreased when particle size was increased from 11 to 1000 nm. TiO₂ nanoparticles of ∼11 nm size of anatase phase exhibited superior decontamination properties relative to larger ones. 100% of HD was decontaminated on their surface within 6 h with irradiation of light. Without irradiation, only 24.7% of HD was removed. GC-MS data indicated decontamination of HD to acetaldehyde, CO₂, sulfur mustard sulfoxide, thiodiglycol, acetic acid, etc. due to photocatalysis. Without irradiation only hydrolysis products of HD like thiodiglycol were observed to be formed.

Nagarajaiah, H. published the artcileSequential One-Pot Synthesis of 2-Aminothiazoles Using Corresponding Ketones: Insights into Their Structural Features, Safety of 1-(4-Chlorophenyl)thiourea, the publication is Polycyclic Aromatic Compounds (2022), 42(4), 1909-1919, database is CAplus.

2-Aminothiazoles have been synthesized by a one-pot, two-step sequential procedure in solution state which does not involve the isolation of intermediates. It involves α-halogenation of corresponding precursor ketones followed by condensation with substituted thiourea derivatives All the products were analyzed by IR, NMR, mass spectral techniques and four of them were evaluated crystallog. One of them crystallizes in the triclinic crystal system with space group P, while, all the other compounds crystallize in the monoclinic crystal system in two different space groups viz. P2₁/c and P2₁/n. The modified 2-aminothiazole core did not show any change in the intermol. interaction. The N-H… N interaction predominates over other interactions forming centrosym. head to head dimer with the neighboring atoms. This feature is observed in all the mols. except N-(4-(4-bromophenyl)-3-(2,5-dimethylphenyl)thiazol-2(3H)-ylidene)-2,5-dimethylaniline.

Novel spiroaminodihydropyrroles probing for optimized interactions at the P3 pocket of β-secretase 1 (BACE1) were designed with the use of free energy perturbation (FEP) calculations The resulting mols. showed pIC₅₀ potencies in enzymic BACE1 inhibition assays ranging from approx. 5 to 7. Good correlation was observed between the predicted activity from the FEP calculations and exptl. activity. Simulations run with a default 5 ns approach delivered a mean unsigned error (MUE) between prediction and experiment of 0.58 and 0.91 kcal/mol for retrospective and prospective applications, resp. With longer simulations of 10 and 20 ns, the MUE was in both cases 0.57 kcal/mol for the retrospective application, and 0.69 and 0.59 kcal/mol for the prospective application. Other considerations that impact the quality of the calculations are discussed. This work provides an example of the value of FEP as a computational tool for drug discovery.

Golubeva, E. N. published the artcileInfluence of the nuclearity of copper(II) chloride complexes on their activity in catalytic C-Cl bond metathesis, Formula: C19H34ClN, the publication is Kinetics and Catalysis (2008), 49(5), 737-742, database is CAplus.

Catalytic systems containing mainly mononuclear (CuCl₄^2-) or dinuclear (Cu₂Cl₆^2-) tributylbenzylammonium chlorocuprates are prepared by adsorption on silica surfaces of different structures (Aerosil and Silokhrom). Using ESR, XANES, and electronic spectroscopy, the CuCl₄^2- ions are shown to be reduced rapidly under conditions of C-Cl bond metathesis, whereas the dinuclear chlorocuprates are relatively stable. A correlation between the number of copper ions in the chlorocuprate anion and its catalytic activity is established: the mononuclear complexes are several times more active than their dinuclear counterparts.

Chantler, Thomas published the artcileProximity effects in the electron impact mass spectra of 2-substituted benzazoles, SDS of cas: 51656-68-9, the publication is International Journal of Mass Spectrometry (2004), 236(1-3), 65-80, database is CAplus.

The 70 eV electron impact mass spectra of a wide range of 2-substituted benzazoles are reported and discussed. Particular attention is paid to the mechanistic significance and anal. utility of [M-H]⁺ and [M-X]⁺ signals in the spectra of benzazoles in which the 2-substituent contains a terminal aryl group with one or more substituents, X. Loss of H^• or X^• occurs preferentially from an ortho-position from ionized 2-benzylbenzimidazoles, 2-phenethylbenzimidazoles, 2-styrylbenzimidazoles, 2-styrylbenzoxazoles and 2-styrylbenzothiazoles. In the three styrylbenzazole series, the [M-H]⁺ and/or [M-X]⁺ signals dominate the spectra. This unusually facile loss of H^• or X^• may be attributed to a proximity effect, in which cyclization of the ionized mol. is followed by elimination of an ortho-substituent to give an exceptionally stable polycyclic ion. Formation of a new five- or six-membered ring by the proximity effect occurs rapidly; cyclization to a seven-membered ring takes place rather less readily; but formation of a ring with only four atoms or more than seven atoms is not observed to a significant extent. The proximity effect competes effectively with loss of a Me radical by simple cleavage of an Et, iso-Pr and even a t-Bu group in the pendant aromatic ring of ionized 2-(4-alkylstyryl)benzazoles.
